Endangered Fermented Foods
Through selective breeding and domestication of plants and livestock, the world’s food system has lost diversity to an alarming degree. Crops are monocultures and animals are single species. Journalist and author Dan Saladino argues it’s vital to the health of humanity and our planet to save these traditional foods.
“There’s an incredible amount of homogenization taking place in the last century, which has resulted in a huge amount of concentration of power in the food system but also a decline in the amount of biodiversity,” says Saladino, author of Eating to Extinction. “That agricultural and biological diversity is disappearing and it’s taken us thousands, millions of years for plant, animal evolution to get to this point.”
Saladino was a keynote speaker at The Fermentation Association’s conference FERMENTATION 2022, his first in-person talk in the United States since his book was released in February. A journalist with the BBC, Saladino was also an active participant in the event, attending multiple days’ worth of educational sessions. He called the conference “mind expanding.”
“I thought I knew about fermentation, when in fact I know very little,” Saladino said to the crowd in his keynote. “We’ve been bemused by the media reports that fermentation is a fad or fashion. What we know is that the modern food system in the last 150 years is the fad. It’s barely a blip in the context of our evolution as species, and it’s the way we’ve survived as a species over thousands of years.”
Eating to Extinction includes 40 stories of endangered foods and beverages, just touching on a fraction of what is happening around the world. To date, over 5,000 endangered items from 130 different countries have been cataloged by the Slow Food Foundation’s project the Ark of Taste.
During FERMENTATION 2022, Saladino centered his remarks around the endangered fermented foods he chronicled in his book – Salers cheese, skerpikjøt, oca, O-Higu soybeans, lambic beer, pu’erh tea, qvevri wine, perry and wild forest coffee. Here are some of the highlights of his presentation.
Salers cheese (Augergne, Central France)
Fermentation was a survival strategy for many early humans, a fact especially evident in the origins of cheesemaking. In areas like Salers in central France, villagers live in inhospitable mountain areas where it’s difficult to access food. In the spring each year, cheesemakers travel up the mountains with their cattle and live like nomads for months.
“It’s extremely laborious, hard work,” Saladino says, noting there’s only a handful of Salers cheese producers left in France. He marvels at “the ingenuity of taking animals up and out to pasture in places where the energy from the sun and from the soil is creating pastures with grasses with wildflowers and herbs and so on.”
Unlike with modern cheese, no starter cultures are used to make Salers cheese. The microbial activity is provided by the environment – the pasture, the animals and even the leftover lactic acid bacteria in the milk barrels. Because of diversity, the taste is rarely consistent, ranging season to season from mild to aggressive.
“The idea of cheesemaking is a way humans expand and explore these new territories assisted by the crucial characters in this: the microbes,” he adds. “It can be argued that cheese is one of most beautiful ways to capture the landscape of food – the microbial activity in grasses, the interaction of breeds of animals that are adapted to the landscape. It’s creating something unique to that place.”
Skerpikjøt (Faroe Islands)
Skerpikjøt “is a powerful illustration to our relationship with animals, with meat eating,” Saladino says. It is fermented mutton and unique to Denmark’s Faroe Islands. Today’s farmers selectively breed their sheep for ideal wool production, then slaughter the lambs for meat. In the Faroes, “the idea of eating lamb was a relatively new concept.” Sheep are considered vital to the farm as long as they’re still producing wool and milk.
Once a sheep dies or is killed, the mutton carcass is air-dried and fermented in a shed for 9-18 months. The resulting product is “said to be anything between Parmesan and death. It certainly has got a challenging, funky fragrance,” Saldino says.
But it contrasts traditional and modern food practices. Skerpikjøt is meant to be consumed in small quantities, delicate slivers of animal proteins used as a garnish. Contemporary meat is served in large portions and meant to be consumed quickly.
Oca (Andes, Bolivia),
In the Andes – “one of the highest, coldest and toughest places on Earth to live” – humans have relied on wild plants like oca, a tuber. After oca is harvested, it’s taken to the Pelechuco River. Holes are dug on the riverbank, then filled with water, hay and muna (Andean mint). Sacks of oca are placed in the holes, weighted down by stones, and left to ferment for a month. This process is vital as it leaches out acid.
“Through processing, this becomes an amazing food,” Saladino says.
But cities are demanding certain types of potatoes, encouraging remote villagers to plant monocultures of potatoes which are prone to diseases. The farmers end up in debt, buying fertilizers and pesticides to grow potatoes.
“For thousands of years, oca and this fermentation technique and the process to make these hockey pucks of carbohydrates and energy kept them alive in that area,” Saladino says. “It’s a diversity that is fast disappearing from the Andes.”
O-Higu soybeans (Okinawa, Japan)
The modern food industry is threatening the O-Higu soybean, too. It was an ideal soybean species – fast-growing, so it can be harvested before the rainy season and the arrival of insects.
“But by the 20th century, the soy culture pretty much disappeared,” Saladino says.
With World War II came one of America’s biggest military bases to Japan. U.S. leaders dictated what food could be planted on the island. Okinawa was self-sufficient in local soy until American soy was introduced.
Lambic Beer (Belgium)
Saldino explained that, after a spring/summer harvest, Belgian farmers became brewers. They used their leftover wheat to create brews unique to the region.
But by the 1950s and 1960s, larger brewers began buying up the smaller ones. Anheuser-Busch InBev now produces one in four beers drunk around the world.
“There [is] story after story of these distinctive, unique, small breweries disappearing as they are bought up or absorbed into this growing, expanding empire of brewing,” Saladino says. “It’s probably one of the most striking cases of corporate consolidation of a drink and food product.”
Saladino stressed not all is lost. He shared stories of scientists, researchers and local people trying to save endangered foods, collecting seeds, restoring crops and combining traditional and modern-day practices to preserve the world’s rare foods.
“There have been so many fascinating stories of science and research discussed over the last few days at this conference, and I think the existence of The Fermentation Association is exciting because it is bringing together tradition, culture, science, culinary skills, all of these things we know food is,” Saladino added. “Food is economics, politics, geography, anthropology, nutrition. What I’m arguing is that these clues or glimpses into the past for these endangered foods, they’re not just some kind of a food museum or an online catalog. They are the solutions that can help us resolve some of the biggest food challenges we have.”

Chicago: A Fermentation Hub
If you still think of hot dogs and deep dish pizza as the icons of Chicago’s culinary scene, you need to think again. The so-called “Capital of the Midwest” is a hub of innovation in the food industry. Chicago has the largest food and beverage production in the U.S., with an annual output of $9.4 billion Startup companies in the region raised $723 million in venture capital last year.
“Chicago is one of the most diverse cities for eating,” says Anna Desai, Chicago-based influencer of ‘Would You Like Something to Eat’ on Instagram. ”Our culinary scene is constantly elevating and evolving. We are always just a neighborhood or tollway away from experiencing a new culture and cuisine. I’m most excited when I find an under-the-radar spot or discover a maker who can pair flavors and ingredients that get you curious and wanting more.”
Desai wanted to celebrate and champion the Asian American and Pacific Islanders (AAPI) community in the Chicago food and beverage scene. She says “food has long served as a cultural crossroad” and Chicago’s multicultural cuisine exemplifies that sentiment.
Chicago is home to some of the most creative minds in fermentation, from celebrity chefs, zero waste ventures, alternative protein corporations, the world’s largest commercial kefir producer and plenty of regional and artisanal producers lacto-fermenting vegetables, brewing kombucha and experimenting with microbes in food and drink.
“Chicago is a great food city in its own right, so naturally there is a ton of talent in the fermentation space,” says Sam Smithson, chef and culinary director of CultureBox, a Chicago fermentation subscription box. “The pandemic’s effect on restaurants has also spawned a new wave of fermenters (ourselves included) that are looking for a path outside the grueling and uncertain restaurant structure to display our creative efforts. This new wave is undoubtedly community-motivated and concerned more with mutual aid than competition. There is a general feeling that we are all working towards the same goal so cooperation and collaboration is soaring and we are seeing incredible food come from that.”
Flavor is King
Flavor development is still the prime motivation for chefs to experiment with fermentation. A good example is at Heritage Restaurant and Caviar Bar in Chicago’s Humboldt Park neighborhood.
“Fermentation has been a cornerstone of the restaurant since its inception,” says Tiffany Meikle, co-owner of Heritage with her husband, Guy. “With the diverse cuisines we pull from, both from Eastern and Central Europe and East Asia, we researched fermentation methodologies and histories, and started to ‘connect the dots’ of each culture’s fermentation and pickling backgrounds.”
Menus have included sourdough dark Russian rye bread, toasted caraway sauerkraut, kimchi made from apples, Korean pears and beets and a kimchi using pickled ramps (wild onions). Heritage has also expanded their fermentation program to the bar, where they’ve created homemade kombucha, roasted pineapple tepache, sweet pickled fruits for cocktail garnishes, and kimchi-infused bloody mary mix.
“It’s fascinating to me that there are so many ingredients you can use in a fermented product,” says Claire Ridge, co-founder of Luna Bay Booch, a Chicago-based alcoholic kombucha producer. “People are really experimenting with interesting ingredients in kombucha…I have seen brewers do some of the wildest recipes and some recipes that are very basic.”
Chicago-based Lifeway Kefir is indicative of the innovation taking place in the city. Last year the company expanded into a new space: oat-based fermentation, launching a dairy-free, cultured oat milk with live and active probiotics.
“We’ve spent so many years laying the groundwork in fermented dairy,” says Julie Smolyansky, CEO. “Now we’re experimenting and expanding to see what’s over the next horizon, though we’ll always have kefir as our first love.”
Chicago is home for two inventive fermented alternative protein startups: Nature’s Fynd and Hyfé Foods. Both companies were born out of the desire to create alt foods without damaging the environmental.
“Conscious consumerism is a trend that’s driving many people to try alternative proteins, and it’s not hard to understand why,” says Debbie Yaver, chief scientific officer at Nature’s Fynd. The company uses fermentation technology to grow Fy, a nutritional fungi protein. “Fungi as a source of protein offer a shortcut through the food chain because they don’t require the acres of land or water needed to support plant growth or animal grazing, making fungi-based protein more efficient to produce than other options.”
Alternative foods outlasting the typical trend cycle is a challenge for companies like Nature’s Fynd. When grown at scale, Fy uses 99% less land, 99% less water and emits 94% fewer greenhouse gasses than raising beef. But, to make an impact, “we need more than just vegans and vegetarians to make changes in their diets,” Yaver adds.
Numerous companies are using fermentation as a means to eliminate waste. Hyfé Foods, another player in the alternative protein space, repurposes sugar water from food production to create a low-carb, protein-rich flour. Fermentation turns a waste product into mycelium flour, mycelium being the root network – or hyphae (hence the company name) — of mushrooms.
“[We’re] diverting input to the landfill and reducing greenhouse gas emissions at scale,” says Michelle Ruiz, founder. “Hyfé operates at the intersection of climate and health, enabling regional production of low cost, alternative protein that reduces carbon emissions and is decoupled from agriculture.”
Symmetry Wood is another Chicago upcycler. They convert SCOBY from kombucha into a material, Pyrus, that resembles exotic wood. Founder Gabe Tavas says Pyrus has been used to produce guitar picks, jewelry and veneers. Symmetry uses the discarded SCOBY from local kombucha brand Kombuchade.
Many area restaurants and culinary brands also use fermentation to preserve food for the long Chicago winters, when local produce isn’t available. Pop-up restaurant Andare, for example, incorporates fermentation into classic Italian dishes.
“Finding ways to utilize what would otherwise be waste products inspired our initial dive into fermentation. The goal is not just to use what’s leftover, but to make it into something delicious and unique,” says Mo Scariano, Andare’s CEO. “One of our first dishes employing koji fermentation was a summer squash stuffed cappellacci served with a butter sauce made from carrot juice fermented with arborio rice koji. Living in a place with a short grow season, preservation through fermentation allowed us access throughout the year to ingredients we only have fresh for a few weeks during the summer.”
Despite growing interest and increasing sales, fermenters face some significant hurdles.
Smithson at CultureBox says he sees that consumers are open to unorthodox, less traditional ferments. Though favorites like kombucha and sauerkraut dominate the market, “their share is being encroached on by increasingly more varied and niche ferments.” But getting these products to market can be a challenge. Small-scale, culinary producers are challenged by the regulatory hoops they need to jump through to legally sell ferments – especially unusual ones a food inspector doesn’t recognize.
“The added layer of city regulations on top of state requirements, sluggish health department responses, and inflexible policy chill the potential of small producers,” Smithson says. But he highlights the recently-passed Home-to-Market Act of Illinois as positive legislation helping startup fermenters.
Consumer awareness and education are also vital. “Many longstanding and harmful misconceptions on the safety and value of fermented products still exist,” Smithson says.
Matt Lancor, founder and CEO of Kombuchade makes consumer education a core part of marketing, to align kombucha as a recovery drink.
“Most mainstream kombuchas are marketed towards the yoga/crystal/candle crowd, and I saw a major opportunity to create and market a product for the mainstream athletic community,” he says. “We’re on a mission to educate athletes and the general public about these newly discovered organs [the gut] – our second brain – and fuel the next generation of American athletes with thirst quenching, probiotic rich beverages.”
Product packaging provides much of a consumer’s education. Jack Joseph, founder and CEO of Komunity Kombucha, says simplicity is key.
“People are more conscious of their health now, more than ever before,” he says. “So now it comes down to the education of the product and creating something that is transparent and easy for the consumer to digest.”
Sebastian Vargo of Chicago-based Vargo Brother Ferments agrees.
“Oftentimes food is considered ‘safe’ due to lack of microbes and how sterile it is,” he says. “Fermentation eschews the traditional sense of what makes food ‘safe’. We need to create a set standardized guide for fermented food to follow, and change our view of living foods in general. One of the brightest spots to me is the fact that fermentation is really hitting its stride and finding its place in the modern world, and I don’t see it going anywhere but up in the near future.”

Brewing Boom in Chicago
Dubbed the craft beer capital of America, Chicago has a brewery scene that is innovative and diverse. Numerous breweries have opened over the last decade, with now about 160 breweries across the city and surrounding suburbs. Ferment Magazine says Chicago’s craft brew industry is “one of the most expressive and most exciting experiences anywhere in the world, let alone in the U.S.”
“We have a very strong culinary scene in Chicago and a lot of consumers that have an open mind. There’s a lot we could throw at the market and people are very accepting of the different brewing styles, both old world and new world,” says Tyler Davis, founder and director of fermentation at Duneyrr Artisan Fermenta Project. “Of all the [different beer styles] we could produce, there are brewers in Chicagoland that specialize in that.”
Duneyrr (pictured) focuses on co-fermentation. Using craft beer as a base, Davis makes fermented drinks with ingredients from wine, cider and mead.
“It all came from me reaching the end of my creativity in a brewery. I got tired of creating the same format,” says Davis, who worked in Chicago as head brewer at Lagunitas and at Revolution Brewing. He began experimenting with co-fermentation and found “how you ferment wine is shockingly similar to beer. There are nuances of both, but I enjoy blurring the lines.”
The Nordic-inspired drinks he produces include his favorite, Freya Franc,(a sour hybrid with passion fruit and Sauvignon Blanc grape must. Duneyrr also has a Moderne Dune line, a sister brand that specializes in modern ingredients and techniques.
Davis studied at the Chicago-based Siebel Institute of Technology, the oldest brewing school in the U.S. and alma mater to many area brewers. One alum is Dave Bleitner, who founded Off Color Brewing with his Siebel classmate, John Laffler. The two focus on funky fermentation.
“Even with our first flagship gose, Troublesome, we have always been fermentation-focused. Even when we are dumping in a bunch of rooibos tea and pumpkin pie spices into a beer, we believe beer needs a proper fermentation to work,” Bleitner says. “Maximizing flavor from yeast is always going to result in a superior beer. But beyond our focus on fermentation, we are not afraid to dump a bunch of rooibos tea and pumpkin pie spices into a beer. So the dual concepts of focusing on the basics of fermentation while teetering on the border of innovative and insane is something no one else should or can replicate.”
When Off Color launched in 2013, Bleitner and Laffler didn’t want to go the mainstream craft beer route. “We had some crazy idea that craft beer consumers wanted variety from their beer,” Bleitner said. They didn’t follow the usual craft beer formula of launching with an IPA. They started with lesser-known styles like gose and kottbusser. He notes “we really hit our stride with Apex Predator Farmhouse Ale.”
At 15 years old, Half Acre Beer is one of Chicago’s pioneers of the craft beer scene. The brewery is the third-largest independent brewer in Illinois and now distributes their beer all over the country. They run a brewery and taproom in Chicago. Their best seller is Daisy Cutter pale ale, but they also sell seasonal and monthly varieties.
“These days we’re kind of the older, bigger brewery among the smaller, newer breweries. We focus on hop-forward and traditional beers,” said Gabriel Magliaro, president of Half Acre. He echoed the sentiment expressed by Duneyyr and Off Color – Chicago brewers are a supportive community. “Today I think we can call Chicago a beer town and, no matter how you choose to define that, we show up well.”
The Next Beer Buzz
Craft beer brewers see increasing competition from the better-for-you, healthier fermented drinks, like kombucha, seltzer and low- or non-alcoholic beverages.
Duneyrr is starting to specialize in lower-alcohol fermented brews. Off Color, too, has added a lower-alcohol beer, a 2.5% ABV Belgian-style they call Beer for Lightweights.
Lagers are making a comeback as well. “A lot of old world brewing styles, there’s become a renaissance,” Davis says. He sees “candy beers” – filled with artificial flavors – going away. Bleitner, too, is not a fan – he calls hard seltzers “fermented pixie sticks”. But he’s found that consumers like flavor in their brews. When sales of Off Color’s Troublesome gose began to decline, adding lime juice revived the drink. They called it Beer for Tacos and “it took off almost immediately.”
In an era fraught with pandemic shutdowns, retail inflation and supply chain issues, brewers foresee challenges ahead.
“Obviously the pandemic has been a factor, one that is still playing out,” Magliaro says. “The on-premise was rocked and I don’t think anyone knows how that will look in five years.”
Climate change is affecting grain crops, “things we knew to be stable are now being highly influenced by the weather patterns,” Davis says. The hot weather is changing the nutrient level of grains, leading to grains higher in protein. “It’s pretty scary,” he says.
But beer will always find a way to thrive.
“We make something embedded in human culture,” Magliaro says. “Beer is a gathering liquid that has place almost anywhere for almost any occasion with so much heritage to its being. The industry, consumer landscape and world can do what it needs, but beer will live on.”

Bubbling Over: Chicago Fermentation Scene
In anticipation for our conference FERMENTATION 2022 in Chicago, TFA asked over a dozen area fermenters about what they love about the city’s fermentation scene. Their answers touched on a number of points: creativity in foods and beverages, diverse offerings, scrappy and determined founders, supportive community and evolving foodscape.
Below are the answers from three local fermentation experts – kefir company founder Julie Smolyansky (Lifeway Kefir), local ferments producer Sebastian Vargo (Vargo Brother Ferments) and chief scientific officer Debbie Yaver, PhD (Nature’s Fynd).
The question: What do you love about the Chicago fermentation scene?
Julie Smolyansky, Lifeway Kefir
Chicago is a true melting pot. We have diversity, talent, and lots of skilled manufacturing talent. It’s one of the premier food cities in the world and I’m so grateful that we’ve been able to build our business and community in Chicago. The natural foods, fermentation, and dining scene all commingle to create opportunities for a special type of risk-taking that’s uniquely Chicago. Lots of it bubbles under the radar – who would have guessed that the kefir capital of the United States is in the Midwest?
Sebastian Vargo, Vargo Brother Ferments
I love the fact that we are seeing more fermentation than ever, from restaurants to store shelves to folks starting projects at home. I love the community behind it, folks are sharing recipes and exchanging tips and tricks. People don’t have time for gatekeeping anymore.
Debbie Yaver, Nature’s Fynd
I love that it flips the script. For so long Chicago was known as the “Hog Butcher to the World,” but now one of the oldest technologies in the books is experiencing a renaissance. There are lots of companies utilizing traditional fermentation, but not as many in the food space. It’s exciting to be one of the newer kids on the block, to see how different companies are putting fermentation to work, and to get to pull from such a stocked talent pool. Chicago is full of bright minds with deep fermentation experience.

Olfactory properties are central to the wine drinking experience. But a chemical reaction known as light strike can ruin the rich aroma. When wine is exposed to ultraviolet or high frequency visible light, its smell can resemble marmalade. Sauerkraut or even wet dog.
This is why wine is stored and aged in dark bottles – the color glass is crucial to producing a great wine.
“Every technician knows about it,” says Fulvio Mattivi, a food chemist at the Edmund Mach Foundation in Italy. “But then the final decision as to what goes on the market is up to the head of marketing.”
Mattivi and collaborators recently published a paper in the Proceedings of the National Academy of Sciences detailing how bottle color affects light strike in wine on grocery store shelves.
Clear bottles made of a refractive material called flint glass are often used to sell white wine and rosé, to show off the fermented beverage’s color. The new research shows that just a week on supermarket shelves in clear bottles can produce smelly compounds. “With exposure, you can have a very bad wine,” Mattivi said. This chemical origin of light strike, including the speed and conditions, has been unknown until Mattivi’s study. In his team’s research, more than 1,000 wine bottles in different grocery store conditions were studied.
Despite consumer preferences for clear bottles, Mattivi gives a hard “no.” He compares it to the folk tale, “The Emperor’s New Clothes.” In the Hans Christian Andersen story, the emperor is conned by swindlers into believing the new clothes they bring him are beautiful – but, in reality, there are no clothes and the emperor is naked.
Mattivi said: “Wine in clear bottles is naked.”

The “Tip of the Iceberg” of Fermented Foods
There’s a huge amount scientists worldwide still need to learn about fermented foods. “We’re really at the tip of the iceberg, as far as I’m concerned,” says Paul Cotter, professor and head of Biosciences at Teagasc Ireland.
“If you think of the vast variety of fermented foods from all across the globe – from East Asia, from Africa, from South America – we really haven’t studied these in any great degree at all, maybe some very basic study, but no microbiome analysis,” Cotter continues. “So really not fully appreciating what’s in there or really harnessing those foods for broader society.”
Cotter, Bruno Pot (science director at Yakult Europe) and Maciej Krol (founder of mac.ferments) discussed fermented foods at a panel at this year’s Probiota conference in Copenhagen. In an interview with NutraIngredients – which wrote “fermented foods took center stage” at the conference – Cotter and Pot discussed the opportunities and challenges of fermented foods.
Expanding the Study of Fermented Foods
Modern technology continues to advance, allowing DNA sequencing and complex analysis of food. It’s of “critical importance” that we further study fermented foods, Cotter adds.
For example, there have been numerous randomized controlled trials with dairy kefir that confirm health benefits. But the results were shown to be dependent on the probiotic strains used – one could help reduce cholesterol, while another would address the gut-brain axis.
“If you don’t happen to have the right one in your kitchen, you’re not benefiting from it,” he says. “By carrying out in-depth investigations of the microbiomes and the metabolites that they produce, you can get a better sense as to what foods have the right microbes for you and to make almost a personalized type of fermented food for each person.”
Cotter stresses studying the foods individually rather than fermentation as a whole. There are specific foods, unique to a country or culture and produced on a small scale, “that we know very little about and might have fantastic health attributes.” He fears that, if these foods aren’t studied, the populations that traditionally make them will die off or move, and their approaches to making these foods will be lost.
Pot points to the fact that non-communicable – “New Age” – diseases emerged and began to increase as food production became more commercialized.
“We need to promote (the) intake of live microorganisms,” Pot says. The public needs to be told “how important it is to maintain healthy conditions in their gut.”
Pot is pushing for a microbes category to be included in dietary recommendations. A late 2020 study published in The Journal of Nutrition officially introduced the idea that a daily intake of microbes could improve health. He compares it to the definition of dietary, which helps educate the public about the kinds of fiber important in a healthy diet.
“The purpose of creating a category is really to allow easier communication with the consumer about the importance of live microorganisms in the diet,” Pot says. “The creation of this category will be a first step.”
Any recommendations, he adds, must be based in science. But it can be challenging to try to educate consumers about often complex scientific topics. It’s important for messaging to be simple, Cotter adds.
“Unless you have a means of explaining to the consumer what are these benefits, then you’re running into great difficulty,” he says.
Today, the public is more conscious today of immune health, and views fermented foods as natural and functional. Cotter believes, if it can be scientifically proven that dietary microbes should be consumed daily, legislators and regulators will add it to dietary guidelines.
Artisanal vs. Large Scale
Cotter sees the future of fermented foods tied to compromise between large- and small-scale producers. Industrialized ferments need to be tweaked to more closely resemble artisanal foods, while artisanal products need to become more readily available to the public at large.
“Fermented foods are quite often very healthy, but the health benefits aren’t fully appreciated because they haven’t been studied in great depth,” he says. “Typically, when those foods have been converted to make them on a large scale by an industry for production to try to make a product that’s available to as many people as possible, the microbiology of the food is very much simplified.”
On the other hand, it’s challenging to “harness the health benefits associated with artisanal foods” when a small brand scales up.
“I think there’s an opportunity for the two to meet in the middle,” Cotter says. “Retain artisanal qualities associated with food but make them available to as many people as possible for mass production.”
Mixed Culture Beer Fermentation
Just because you’ve pitched an exotic fermenting agent into your beer doesn’t mean the hard work is done. Mixed-culture fermentations are becoming increasingly popular choices for brewers looking to add complexity to their beers. But, as an article in Craft Beer & Brewing details, using a mixed array of yeasts and bacteria requires greater attention to the fermentation process.
“Just because it’s a wild beer doesn’t mean that you can be careless,” says Patrick Chavanelle, R&D brewer at Allagash in Portland, Maine. “Be as meticulous when crafting a mixed-fermentation beer as you would when brewing a beautifully crisp lager.”
Mixed fermentation uses multiple microorganisms as fermenting agents. The most common are yeasts Saccharomyces (known as brewer’s yeast) and Brettanomyces, and the bacteria Lactobacillus and Pediococcus.
The article advises brewers to: embrace uncertainty, focus on pitch rate, pay attention to choice of fermentor, research the yeast or bacteria used and consider post-fermentation doctoring.

Mead appealed to David Lane because of the fermentation challenge: it’s hard to make a bad wine, but easy to make a bad mead.
“Honey sometimes needs various chemical nudges,” he said. “It’s a big puzzle figuring out how to get the chemistry just right for each varietal.”
His Oregon-based brand, Wild Nectar Mead, is made with honey from local honeybees. Interacting with their beekeepers made Lane even more passionate about mead. He learned about the dangers of honeybee extinction and the importance of local pollinators. He calls it his “bee-cause.”
Each mead flavor reflects the essence of a variety of honey, such as basswood, clover or wildflower. Lane says he loves these flavor differences.
Lane also has taken a different approach to production. Many purists believe a good mead needs months-long fermentation. Lane has tinkered with a process that takes only a month.
“(Mead) has a long history, but then it fell out of favor with history,” Lane said. “So it feels like a comeback drink to a lot of people.” Read more (auburnpub.com)

Fermented Foods and Running
Fermented foods continue to top nutritionists’ lists as a key healthy and functional component in the ideal human diet. In a new article in Runner’s World, a registered dietician recommends runners eat fermented foods to meet nutrition needs, improve their health and better support their training.
The author lists four reasons to eat fermented foods: improve the gut microbiome, add a nutritional upgrade, aid digestion and improve protein intake.
“Recent research even suggests that the makeup of our microbiome may also play a role in how our muscles adapt and develop in response to exercise. And fertilizing your gut with more desirable bacteria via fermented foods may payoff with better digestive functioning during periods of hard training and throughout long races (read: fewer sprints to the nearest port-a-potty),” the article reads. “To date, the literature suggests that probiotic foods (like fermented foods) are still the preferred method of obtaining probiotics rather than relying on supplements.”
