As a biochemistry grad student with a penchant for homebrewing, Chris White never thought his growing collection of yeast strains would amount to anything outside a hobby. But when White graduated with his PhD and was offered a lucrative job in the biotech field, one caveat kept him from accepting the offer — there were no side jobs allowed.
“I never had some big plan to start a company. But I liked all the fermentation stuff I was doing and didn’t want to let go of my yeasts,” says White, CEO and founder of White Labs. “I said no to the job, and from there White Labs kept going and going and getting bigger and bigger.”
Today, White Labs is a powerhouse in the fermentation industry. They provide professional breweries with liquid yeast, nutrient blends, educational classes, analytic testing and private consulting.
White Labs is celebrating a landmark 25th anniversary this year, despite a global pandemic that has shuttered breweries. They have released their own line of beer, created a new nutrient blend for hard seltzer brands, began a YouTube series and launched free how-to education classes for homebrewers. White Labs will host a year in review webcast on Dec. 9.
“We’ve had a lot of success and we’ve made a lot of mistakes, and we’ve tried to learn from those mistakes. But we’re a team. And we really got lucky that we hired people interested in fermentation that helped build this company,” White says. “Everyone really pulled together during COVID and did whatever was needed. It’s been a great experience because we had solutions and we had teamwork. And I think it’s taken 25 years to get to that team, that tribe.”
A yeast guru, White is a co-author of the book “Yeast: The Practical Guide to Beer Fermentation.” Below, check out our Q&A with White.
The Fermentation Association: You studied biochemistry at University of California, Davis, then got your PhD in biochemistry at University of California, San Diego. What made you decide to dive into yeasts?
CW: I was always interested in science since high school chemistry, and then in college was interested in how cells work, how DNA worked. It drove me to where I am today, really. Most people I went to school with at UC Davis, they were studying biochemistry to be a physician. But that’s not what I wanted to do, I was more interested in biotech and grad school.
Meanwhile, I was homebrewing. It was a great combination of things that happened. The science and homebrewing is what led me to put that together and make yeast for homebrewing, then yeast for craft brewing.
TFA: Is that what led you to start White Labs?
CW: It really was. I like beer. I was fascinated with how it could be made. It’s pretty simple to make beer — simple, but not easy. It’s difficult to make a great beer. But it’s fairly simple since it’s only four ingredients if you include the water. That’s what’s great about a lot of fermentation, the raw materials are all around you. They’re simple. Making it taste good is the hard part, that’s the art of it. I liked beer, I really got into homebrewing, then the people I was making homebrewed beer with started a store in San Diego, Home Brew Mart, in 1992. We became friends and that’s who I was homebrewing with every weekend. Then my friend from the store said “Hey, we need yeast,” and I started a little company on the side to make yeast. It wasn’t like I had some big plan to start a company, I thought I’d just make a little each week. And then other people asked and other people asked. By the time I got closer to finishing grade school, I just didn’t want to stop doing the yeast for brewing.
TFA: Now there are over 1,000 strains of yeast in the White Labs yeast bank. Tell me about it.
CW: We have a yeast bank that I spent a lot of time building in the beginning, more for my own brews, but obviously later on, it became more and more. The foundation of our company is our yeast strains and the way we store them. We’re collecting strains all the time. But what I did in the beginning was collect different strains from travel, from different yeast banks. We created our own private yeast bank at White Labs, but there are yeast banks around the world. Especially in Europe where brewing really began in an industrial way and where yeast was discovered and started to get collected. There’s a great yeast bank in Denmark, Germany, the UK. I spent a lot of time acquiring strains from those.
You get to know the yeast in a different way, the strains, what they do. Performance, conditions. But for beer especially, it’s really how they taste, which is so important. We only make those flavors through fermentation. We still continue to acquire strains. People send them to us, we bank private strains for companies, sometimes they buy them in a liquid form we make for them, sometimes we just store it for them. But usually, they’re banking it for us to make something with it.
TFA: Besides yeast, White Labs offer testing services as well.
CW: White Labs Analytical Lab is really separate in the fact that a lot of people that work in that lab don’t really have anything to do with the yeast. It’s just testing samples. They’re usually fermented beverages. Yes, there’s beer there, but that’s just a part of White Labs Analytical Lab. There’s the spirits that come for testing, kombucha, cider, mead, any kind of commercial business making a fermented beverage that needs some kind of testing. Sometimes it’s regulatory for export. Sometimes it’s just for their own data, like actual alcohol by volume instead of calculated, sometimes it’s microbiology or tracking down a problem or contamination. It’s all confidential, like everything at White Labs. But we get to work with a lot of cool companies, a lot of them may not get yeast from us, that’s really not a requirement. The yeast and testing run separate.
TFA: Have you seen kombucha brewing grow?
CW: Oh yeah. Originally, that’s how we got into analytical testing because people were asking for alcohol lab evaluations, which is so important in kombucha. We all know what happened there (Whole Foods pulled all kombucha bottles off shelves in 2010 after several brands tested at higher alcohol beverage levels then what was printed on the bottles). And it happened because it’s a biological process. You put that thing in a bottle and it’s going to keep fermenting. People had to really try to figure out what to do with that. So a lot of alcohol testing, and a lot of that is regulatory in kombucha.
But then we started making SCOBYs because a couple of our staff got really into it. Just like I started making yeast in my own home brewing, they started making SCOBY in White Labs for their own kombucha making. So we said “Let’s sell it.” And now we make a bunch of it.
TFA: That’s forward-thinking, expanding your offerings to all fermented drink products.
CW: Yeah and the different facilities allow us to do different things. We grow all the SCOBYs in North Carolina because it was a new facility at the time and had the space, San Diego is full.
TFA: White Labs released their own canned beer in July. Tell me about it.
CW: A lot of the things that came out of this year really were not new ideas, like canning. Someone gave a presentation at White Labs during one of our internal innovation summits that’s open to anyone in the staff about canning beer. But during this time of COVID, when we’re not focusing on growth, we were able to work on a lot of those projects and really build a better company. Once we gave up the idea that revenue is not going to go up right now, we worked on other things. And it’s been great. A lot of cool things have been coming out of our teamwork this year, and one of those was canning.
So we said let’s do that because we’re not selling beer in our tap room — we’ve got a tap room in San Diego for White Labs Brewing Company and a kitchen and tap in Asheville, it’s more of a full restaurant. We weren’t selling a lot of beer and we have a lot of beer, so why not can it? We have done three different beers now in cans. The IPA, a hazy IPA and the pilsner. And we’re going to do another lager and IPA next month. It’s been fun for the brewers to be able to brew it. I think it’s been a nice boost for everyone in the company, not even money wise, just to have another milestone: we put our beers in cans. It’s a nice billboard for the brewery. And they get to have fun with graphics, and how to tell our story, and really share what we’re doing in the tap rooms.
People are amazed that it’s the same beer, same exact batch but put into smaller fermenters and pitched with two different yeast strains. They say “Wow, you created different flavor beers? They taste different?” Yeah, because that’s fermentation. Fermentation makes these flavors and when people taste that it’s the same exact beer made with two different yeast strains, they get it in 30 seconds. “Oh that’s what a yeast does?” But you have to come to our tap room to experience that. And obviously during these times, you can’t come to the tap room. But canning is a way to share that with people outside the tap rooms.
TFA: Who buys more yeast from White Labs — commercial producers or homebrewers?
CW: Commercial because of volume. But we’re available for everything in homebrew. We try to mirror every test, every yeast strain, and make those available for home brewing because that’s our roots and I think it’s important. There’s been growth in home brewing during COVID. People at home with a hobby are buying yeast. That’s kind of nice, I like to see that.
TFA: Craft brewing has been hit so hard by pandemic. What have you seen your clients doing to survive?
CW: They’re getting creative. People had to figure out the to-go thing, first of all. That maybe involved buying software or creating a new website. Each company I talk to, regardless of what industry, they had to do something technology wise. Very few could close the bar door and were all set up to sell everything through the warehouse.
I think customers were also really good about supporting local businesses, wanting to help them. There’s been a lot of to-go. But it still doesn’t compare to all the beer they could sell, all the stuff that gets sold through bars. Even if one little meadery sells more to go, it doesn’t replicate all the tap room business that just disappears.
TFA: What do you think is the future of the fermented drink industry?
CW: It’s up to them. We pay attention so we can be there to help. But really these things come from creative people. New things have to come out. That keeps the industry growing. And I don’t know what those new things are, but we try and pay attention.
I think transparency and honesty is a hallmark of fermentation industries — whether craft breweries or wineries — and I hope that stays. That’s been a big part of the trust with consumers, and the fact that you can do these things at home too, so you know how it’s done. And with new techniques or things that get introduced, I think the industry needs to keep the transparency part of the business. Because fermentation being such an old, old method — a lot of people would like to replace fermentation with something else. They say “Let’s just mix these things together rather than do that weird fermentation.” But weird fermentation is what makes it so special.
Microbial fermentation is emerging as the “third pillar in the alternative protein industry,” alongside cell-culture and plant-based, according to the Good Food Institute. In 2020, protein alternatives made using microbial fermentation have attracted $435 million in investment capital. The institute released a 72-page report on fermentation in the alt protein industry and noted that its “potential is still largely untapped.” Nature Fynd CEO Thomas Jonas points out it takes years to grow animals, and months or years to grow plants, but microbes can double their biomass in a few hours. Are these novel fermentation techniques to produce animal-free meat and dairy improving our food system or too big of a departure from traditional fermentation?

Creating a HACCP plan — a management system to control food preparation risk — can overwhelm food producers. But Charlie Kalish, food safety consultant and trainer, emphasizes HACCP (Hazard Analysis Critical Control Points) is vital to food safety.
“This is just as important as trying to understand, when I ferment things, why do I ferment? What are the things that get you excited about why you get the flavors that you get or the textures that you get (when you ferment)? The food safety thing, it’s really going to help you in the long run if you approach it with the same excitement because, if you don’t, it’s going to be a lot of work and it will drag you down,” Kalish says during the recent TFA webinar Introduction to HACCP. “I see a lot of people get bitter about (HACCP). ‘It’s such a drain on my resources and what I do!’ But it can help your product get better, it can help you get into new markets. And it is a different language, a different world. Even if you’re not going to get a PhD to understand the basic science underlying the mechanisms, having a strong control of HACCP, food safety, what the expectations are, it’s really going to help you.”
HACCP was originally created for the space program in the ‘60s. NASA needed a high level of assurance that food was going to be safe during missions in space, but traditional food models did not have enough preventive food safety controls. That plan was later adopted by the USDA and FDA to regulate food products.
“HACCP shifted the focus away from recalling food and trying to do damage control with outbreaks to preventing those things from happening in the first place,” Kalish says. “HACCP, in summary, is a systematic approach where we consider all of our ingredients, we consider every process step from when we receive our raw materials or ingredients all the way to the shipping out of our final product, it considers all reasonable and foreseeable hazards.”
Kalish points out HACCP controls for things with a high probability of occuring, like an E. Coli outbreak in lightly fermented food. And a good HACCP plan begins with a solid foundation, basic practices like regular hand washing, sanitizing surfaces and maintaining a comprehensive food safety employee training program.
“Common sense is an excellent guide to get you started for food safety, but I would further suggest to learn as much as you can: the science of the system you’re working with, the microbiology, pH, what it is, how you measure it,” says Fred Breidt, PhD, a microbiologist with the Agriculture Research Division of the USDA. Breidt joined Kalish during the webinar along with moderator Dave Ehreth, president of Sonoma Brinery; both are TFA advisory board members.
Luckily for fermenters, fermentation is a critical control point. In one study on kimchi by Breidt and his USDA colleagues, they found pH level is critical for food safety, a factor controlled by fermentation.
Though the internet can be a wonderful resource to find information on food safety, “you have to be judicious about your sources,” Breidt says. Kalish says to look for guidance from government sources, scientific literature, process authorities, university extension specialists, industry groups and publications or consultants.
Food producers need to budget for HACCP in their financial plan, Kalish advises. Ehreth agrees, and encourages producers still unsure of the process to pay a professional for help “to understand what potential biological hazards could be in that jar of food.”
“The modern food manufacturer is not only a food manufacturer, he is a protector and is entering into a bond of trust with his customers. And that bond of trust says ‘If you buy what I make, you’re not going to die as a result,” Ehreth adds. Though he notes it sounds like extreme advice, it’s a necessity for food producers to keep that creed at the forefront of their production.
There’s a void in scientific knowledge of fermented and pickled vegetables, and scientists are just starting to scratch the surface.
“We have a wealth of chemical compositions that we still don’t fully understand,” says Dr. Ilenyz Pérez-Díaz, PhD, a microbiologist with the USDA-ARS. Perez-Diaz presented on “Development of Pickling Technologies & Products” during a webinar hosted by TFA. “I honestly think there is still a lot to do in regards to the richness of the biological functions that are present in these systems. Every vegetable is different. … It will be fantastic to be able to comprehensively understand what’s really there and how we can use it for the benefit of not only processing but also for the benefit of human health.”
The purpose of the USDA-ARS is to find solutions for agricultural challenges, domestically and globally. In 2019, the 8,000 employees of the USDA-ARS researched 660 agricultural projects, filed 85 new patents, issued 65 new patents, received 51 new licenses and wrote 3,816 peer-reviewed journal articles.
Pérez-Díaz is assigned to the food science and market quality and handling research unit. There the team develops state-of-the-art, science-backed methods that improve the post-harvest processes, food preservation, food quality and safety and, ultimately, introducing nutritious products into the food system.
“What I love about the research that she’s doing is that pickling and fermentation are these ancient, traditional technologies that people have been using for hundreds and hundreds of years, and she’s really thinking about ways that we can advance those technologies using all the amazing sequencing and all the microbiology we have today,” says Ben Wolfe, PhD, associate professor of biology at Tufts University, and the TFA Advisory Board member who moderated the webinar.
Pérez-Díaz shared the USDA’s latest technologies to reduce food waste, lessen environmental impacts, improve water/energy demand and add more health value to preserved vegetables. Here are highlights from the research presented, focused on addressing two key problems:
Eliminate Salt in Cucumber Fermentation
PROBLEM: Sodium chloride is essential to fermentation, but the salt-rich (and sometimes preservative-filled) brine shipped from overseas producers can get into local freshwater supplies. There are no growers of small cucumbers (gherkins) in the U.S., so food projects that require small cucumbers must use overseas produce. But, in order for the cucumbers to be transported, they must be fermented or pickled. High amounts of salt, acid and sometimes preservatives are added, and these potentially can damage the water supply.
SOLUTION: USDA-ARS tested fermenting pickles using three popular spices: dill, cinnamon and mustard seed. But, though salt was reduced or eliminated, “the indigenious microbiota is always there,” Pérez-Díaz explains. “The salt is modulating the activity within this population. It tends to favor the lactic acid bacteria. But what I’ve learned is it is not the main factor modulating that microbiota. The ph and the production of that lactic acid and or acetic acid is really the factor in excluding the non desirable microorganisms and favoring the fermentative microbiota.”
Reduce Food Waste by Creating Foods
PROBLEM: In the U.S., between 30-70% of fresh vegetable produce is wasted. “Those are alarming numbers,” says Pérez-Díaz. “Even though they are estimates, it is necessary to look at ways to resolve the impact of such waste.”
SOLUTION: The USDA developed small-scale fermentation systems for use in restaurants, farmer’s markets and grocery stores. These vessels make fermenting excess food more manageable by allowing easy fermentation of smaller batches.
“We can convert what was waste or surplus or defective vegetables into a value-added product,” Pérez-Díaz says. “It will be a probiotic product, it will be fermented vegetables auxiliaries that can be used as sources of flavor, colors, ingredients in a number of recipes or even dehydrated for different applications.” [This project was near completion before the pandemic and is expected to pick-up soon.]
Fermentation, she emphasized, is needed to sustain a modern food system.
“These fermentations, if applied properly, they are very powerful eliminating the organisms that are not desirable or the organisms that are not of health significance,” Pérez-Díaz says. “I think fermentation will truly be an important component as we move forward to that new era.”
Just because vegetables were fermented does not make them immune to harmful bacteria like E. coli. Though fermentation improves food safety, the quality of the raw vegetable before it’s fermented is extremely important.
“The issue of fermentation safety is one that comes up a lot. People are getting excited about the fermentation world these days, fermentation is increasing in popularity…(but) the wheels can fall off if you’re not careful,” says Fred Breidt, PhD, a USDA microbiologist. Breidt spoke during a recent webinar hosted by The Fermentation Association, “The Science Behind the Safety of Fermented Vegetables.” “The moral of the story: if the vegetables were safe to eat before you ferment them, they’re going to be safe to eat after you ferment them. If they’re not, you’ve got to ferment them for a long time to make sure they’re safe.”
An outbreak of dangerous bacteria in fermented vegetables, “it’s going to be pretty rare that that happens,” Breidt stresses. But, without proper sanitation protocol and vegetable quality control, pathogenic “bad guys” can flourish, like E. coli, salmonella and listeria. E. coli is more common in vegetables because it’s extremely acid resistant, and can survive for long periods of time at low pH levels and cold temperatures.
“Just washing the surface (of the vegetable) isn’t always going to do the trick,” Breidt says. “You don’t have to eat very much to get sick.”
An E. coli outbreak in kimchi made 230 Korean school children sick in 2013. The children, from seven different schools, all ate fermented kimchi made by the same manufacturer.
“If the folks had eaten the cabbage that this kimchi was made out of, they would have gotten sick as well,” Breidt says. “Was the cabbage improved in the sense of maybe it had fewer E. coli on it because of fermentation? Yes. But there was still enough when this was eaten to make a lot of people sick.”
“You can’t rely on salt for safety is the point,” he adds. “It does encourage the lactic acid bacteria and it helps them grow and it will increase overall the safety of your fermentation.”
David Ehreth, president and founder of Alexander Valley Gourmet, parent company of Sonoma Brinery, moderated the webinar. Ehreth first met Breidt when Sonoma Brinery made a few tons of sauerkraut that became infected with yeast. Ehreth says “I called Ghostbusters, and that’s Fred Breidt.” Though yeast is different from a pathogen like E. coli, Ehreth said Sonoma Brinery has managed to control yeast over the years by careful management of production techniques and improved sanitation methods.
California wildfires are destroying an already tough harvest season for wineries in Sonoma County, Napa Valley and the Santa Cruz Mountains. Tony Bugica, director of farming for Atlas Vineyard Management, which farms 3,500 acres on California’s North Coast, says “2020 is like nothing we’ve ever been through.” Even as the fires diminish, wineries are battling power outages and smoke damage. Prior to the fires, the excessive heat, depleted tourism, social distancing restrictions and economic repercussions of the coronavirus pandemic were already making the 2020 grape harvest challenging.

In an effort to help struggling farms during the coronavirus pandemic, Blue Hill at Stone Barns is expanding their fermentation program.
The upscale restaurants (Blue Hill in Manhattan and Blue Hill at Stone Barns in Westchester County) have long been at the forefront of farm-to-table dining. But, like all restaurants in New York, Blue Hill closed in March when the coronavirus pandemic broke out. Though co-owners Dan and David Barber are confident the traditional restaurant model will once again return, the brothers are troubled by the catastrophic impact on farms.
Blue Hill Farm and Stone Barns Center (a non-profit farm and educational center) have partnered to form a new entity resourcED, which surveyed over 500 farmers. A key conclusion — over a third of farms will not survive the pandemic. August sales at farms are expected to be down by 50% due to the COVID-19 pandemic, and over 30% of farmers say they are struggling to cover expenses.
“The excess product is a huge concern. That’s shaped our box program, our fermentation program,” says Andrew Luzmore, Blue Hill’s market forager.
The resourcED survey was the impetus at Blue Hill to launch their picnic dining and box program. Diners can buy a picnic dinner and eat a farm-to-table meal on the farm’s patio or lawn (physically distanced from others), still allowing Blue Hill to purchase food from local farmers. This program allows consumers to pick-up a box full of produce, dairy products, seafood or meat, all sourced from local farms.
Blue Hill’s mainstay fermentation and preservation programs, used for over 15 years to maintain food flavor and nutrients through long Northeastern winters, have also been expanded, to absorb more of excess farm production.
“The focus on preservation program is bred out of necessity, and necessity breeds creativity,” says Cortney Burns, chef, fermentation consultant for Blue Hill and author of “Bar Tartine, Techniques & Recipes” and the forthcoming “Nourish Me Home.” “What we’re doing now with fermentation at Blue Hill rides on the coattails of what has been part of the backbone of Blue Hill for years. Working here has me looking at fermentation through a different lens these days. How can we be completely in service to good agriculture? How can we create a greater economy for farms?”
Adds Luzmore: “The fermentation program has definitely expanded a lot. We’re shifting more to helping farmers with excess product.”
For example, Blue Hill recently purchased napa cabbage that would have been wasted from a Hudson Valley farmer. They are fermenting the cabbage, “making a delicious, nutritious probiotic-rich food for our diners, whilst buying up overabundant harvests,” Burns notes.
It’s conscious cooking, Burns says “We’re not just buying for the sake of preservation. We want to create variety.” Another example is how the Stone Barns Center is trialing preserving different beet varieties.
Fermented grapes and capers, buckwheat vinaigrette, peach umeboshi and whey tonic are among the creations Blue Hill has served picnic-style and in boxes. Some of the fermented food being offered is purchased from local farmers. Local cultured dairy — such as farm fresh cheese and yogurt — makes up a large percentage of their dairy box, for example.
“There are all these different ways we’re harnessing the power of fermentation,” Burns says. “We’ve had to shift our expectation of a restaurant kitchen. We need to make sure that first, the food doesn’t spoil, and second, that we have lots of probiotic rich food loaded with flavor to serve people.”
A picnic meal at Blue Hill is $195 per person and the boxes range from $45 to $170. Blue Hill is also donating boxes to families with food insecurities.
Luzmore hopes other restaurants will innovate ways they can support local farms during the pandemic. “It’s almost impossible to buy exactly the amount a restaurant needs, especially now when there’s a greater need to support farms. Considering the constant and changing flux of product coming into the restaurant for the boxes and donations, fermentation allows for a more holistic approach of using excess product.”
“Chef Dan [Barber] has said many times throughout the launch of resourcED: we’ve kind of gone from being a restaurant to a food processing facility. Blue Hill is a fine dining restaurant. We still maintain that mentality and quality, but it’s at a different level. The scale, we’re now thinking of purchasing pallets instead of pounds.”

The first two months of 2018 marked both my first trip to Mexico and my first bicycle tour. Living on two wheels did not slow my fermentation habit; I toted stainless steel jars of fermented vegetables in my panniers. I credit consuming lacto-bacteria with my lack of stomach troubles that can plague travelers in South America. Regularly introducing healthy bacteria into our digestive tract is a great way of inoculating our body with microbes that are on our team. The amount of attention probiotics have received in recent years is long overdue. Traditional cultures have known about the delicious and health-promoting qualities of fermented foods for hundreds of years, even before it was scientifically proven.
Backslop is Such Beautiful Word
Contamination and inoculation are two sides of the same food processing coin: the impact of a small quantity of the right or wrong material can be drastic. The former is the stuff of nightmares for food companies forced to recall tainted products, and suffering travelers perched atop or hunched over a toilet. The latter is how fermented flavors have been passed down through time, sometimes across generations, from one bottle, crock, or barrel to the next. Inoculation is so ubiquitous to the craft that traditional sausage makers gave it a name: backslop.
Backslop, unsavory as it may sound, simply refers to the practice of saving a bit of the last successful batch and incorporating it into the new one, ensuring a small number of the micro-organisms that populated the previous batch will go forth and multiply. There are several reasons why this technique is valuable to both professionals and home cooks. Foremost, the time required for complete fermentation decreases dramatically. A new jar of sliced cabbage or jug of fresh squeezed fruit juice is teeming with all kinds of bacteria and yeast, some of which will produce the desired results, and some of which will produce something inedible.
By introducing a healthy colony early in the process, desirable microbes get a head start and usually out compete less desirable ones in the race to inhabit a new environment. If those microbes have a particularly unique characteristic (champagne yeast produces more carbon dioxide than other wine yeasts, for instance), that character can be reproduced, sometimes leading to outstanding strains by which certain makers and regions become famous.
A 5-Year Love Affair
In more humble corners of the globe, far from French vineyards, I once had a relationship with a sourdough starter that lasted five years.
A sourdough culture becomes more complex with age, and as time went by she (yes, she—around her first birthday I named her Henrietta) developed her own unique flavor. One morning, I came into my kitchen and saw Henrietta’s container on the floor, licked almost all the way clean. A dog had gotten up on the counter, somehow removed the lid, and all but devoured my precious bread making ally. I scraped the dried crust of starter that remained from the edges of the bowl and rehydrated it with water.
Over the next few days I added a bit more flour and water at regular intervals, and in less than a week my robust friend was back in action. I could have sighed, cursed dogs under my breath, and made a new starter, but I was attached to Henrietta, and thrilled to revive her with such little material.
The beginning fermenter has a few options for ensuring success. Of course, there is always the option of simply hoping for the best. Usually, if the food to be fermented is fresh and healthy and the containers and hands in contact with it are clean, odds are in our favor that the microbes that make things sour and bubbly are going to win. However, a splash of the liquid floating around the top of high-quality yogurt (look for something with “active cultures”) will introduce a bit of the right bacteria and speed the process along. A small slosh of juice from a thoroughly fermented sauerkraut or brined vegetable jar will help get the next one going.
Those interested in experimenting with fermented dough will be delighted to know that a sourdough starter is incredibly easy to make: stir equal parts flour and water every day until it smells sour. Wild yeast lands on top of the mixture and is incorporated with every stirring.
Aid this process by dropping an unwashed and unsprayed berry (grapes work best) into the mixture for a couple of days (retrieve the berry before it starts breaking down). Yeast which covers the skins of all fruits will slough off and populate the latent starter. To keep this culture thriving, the sourdough baker saves a small amount of the starter and adds to it more flour and water. Starters exist that are rumored to be hundreds of years old, passed down in just this way.
Practice Safe Fermenting
Interestingly, foods that are not fermented are more prone to contamination from bacteria that can make us very ill, and in the worst cases, kill us. The culprits in large and small-scale food poisonings are often raw and unfermented vegetables. By fostering beneficial bacteria in a salty and acidic environment, we can safely enjoy raw vegetables with all their fiber and nutrient content without the risk of ingesting pathogens.

Hops used to be the biggest thing in beer to create a powerful flavor — now it’s yeast strains. Brewers are using yeast strains from around the globe for the best flavor.
According to the New York Times: “For some time, it’s been a hopped-up arms race as breweries regularly double or triple the amount of hops to create stronger aromas. With breweries using the same hops, many beers are starting to smell alike. … In search of distinct aromas, brewers are embracing yeast and bacteria strains from across the globe. They’re creating beers that let each type of microbe speak its unique language, and drinkers are listening.”
DeWayne Schaaf, owner of @ebbandflowfermentations Ebb & Flow Fermentations brewery in Missouri, calls himself a “yeast nerd.” He does not use commercial yeasts in his drinks, instead fermenting with yeast strains from Scandinavian farms, bottles of Spanish natural wine and Colorado dandelions. Few hops are required in his drinks as, during fermentation, the yeast converts sugars into alcohol for the flavors.
