The Covid-19 lockdown spurred aspiring home chefs around the world to try fermenting for the first time. DIY classes moved virtual and countertops filled with bubbling crocks of kimchi, sauerkraut, kombucha and sourdough. Fermentation was one of the top pandemic hobbies

For professional fermentation educators, this trend brought new, eager faces to classes. But now, as lockdown restrictions have eased, are people still wanting to experiment making their own microbe-rich food?

We asked three experts to share their thoughts on the current state of fermentation education — author and educator Kirsten Shockey (of The Fermentation School and Ferment Works), writer and educator Soirée-Leone (who can be found via her website) and  chef, food scientist and fermentation educator Jori Jayne Emde (of Lady Jayne’s Alchemy and The Fermentation School). [Shockey and Soirée-Leone are both members of TFA’s Advisory Board.]

The question: What is the current state of fermentation education?

Kirsten Shockey, author and educator

Fermentation education is exploding. The time has never been better. The interest in fermentation — both as a topic and in hands-on engagement — keeps gaining momentum. People are both more curious and more confused than I have seen in the past. I think part of that is because with the boom of  interest a lot of people are coming forward as experts sharing content without the prerequisites to inform accurately. For example, we see misinformation about the subtle differences in fermentation vs. culturing vs. pickling that end up leaving people who are just dipping their toes in the process a little less unsure. When these folx do engage with true experts they are enthusiastic students who enjoy soaking up all that they can and we see their anxieties dissipate. I speak from the experience of working with solid experts and their students through The Fermentation School.  It has been beyond gratifying to work with an amazing group of really talented fermentation educators to grow quality online education and a dedicated “help” community through The Fermentation School. In my other educator hat, as an author, it is less clear to me how that media is working for education, but that is a bigger issue in that the publishing world itself is in a lot of flux. 

Soirée-Leone, writer and educator

Folks are connecting with familial, cultural, and traditional roots through fermentation. They are building online communities to share knowledge, taking workshops, participating in residencies, checking books out from libraries, and attending fermentation festivals that are popping up all over the world.

While there is an abundance of information available through books and websites, some folks seek to connect in person through workshops. I find that it’s especially dynamic to teach and learn in collaborative environments to share skills and experiences. There are so many traditions, techniques, and riffs. It is exciting to learn about folks’ travels, study, and experiments — we each have a different fermentation journey and something to teach and learn.

Today is a far cry from when I first started cheesemaking in 1991 with one slim book that sang the praises of junket rennet. Now there are books sharing natural cheesemaking techniques, bloggers happy to answer questions, travelers bringing information home and sharing online, and workshops to attend.

Fermentation is accessible with rudimentary kitchen equipment and improvised incubators and cheese caves. Fermentation is empowering and engaging of all our senses—and learning new things about fermentation is a never-ending journey.

My perspective on this is it’s booming!  There was a huge burst of interest for online learning during the pandemic, and I have not seen that slow down much.  Fermentation is a trendy topic and word with, unfortunately, a tremendous amount of misinformation floating around out there.  It’s an important time as an educator to really remain engaged with students, as well as capturing fermentation aspirants, guiding them towards proper and well informed education taught by experts in the field of fermentation and health.  

David Zilber says the potential for fermented food is endless. “There isn’t any sort of food that doesn’t benefit from some aspect of fermentation,” he said. “There’s really no limitation to its application.”

Zilber, the former head of the Noma fermentation lab, co-authored “The Noma Guide to Fermentation” with Noma founder Rene Redzepi. In the fall of 2020, Zilber surprised the food world when he left his job at Noma to join Chr. Hansen, a global supplier of bioscience ingredients.

He shared his insight on fermentation on The Food Institute Podcast. An Oxford study found over 30% of the world’s food has been touched by microbes. Zilber, a microbe champion, says one of the best parts of fermenting with plant-based ingredients is the microbes don’t need to change.

“We do need to find ways to adapt them to new sources, but there will always be a place within the pie chart of what humans are eating on earth for fermentation,” he says.

Part of Zilber’s work at Chr. Hansen is in the plant-based protein alternative segment, fermenting plant ingredients to “bring this other set of characteristics” to a new food item. He advises fermenters using plant-based ingredients to make their ingredient list concise and pronounceable to consumers. 

“I am a huge proponent for formulating recipes from whole ingredients,” Zilber says. “Keeping the ingredient list short and concise and using natural processes to achieve flavor or textual properties … because it is the healthiest way to eat.”

Across the spectrum of fermentation, he feels fermented beverages is the category where he sees the greatest opportunity.

Expect more changes to fine dining as the restaurant industry grapples with Covid-19 changes, casual eateries adapt more fine dining techniques and the war in Ukraine continues to affect the world economy.

“Everyday restaurants have become so amazing. It’s not like it used to be, you used to go to the best restaurant to get the most tender piece of meat and the perfect ice cream,” says Rene Redzepi. He is the founder of Noma, the Michelin three-star restaurant in Copenhagen lauded as one of the top in the world. “You can find typical luxury ingredients like caviar and wagyu in airports. The quality of cooking now is so high.”

Redzepi spoke at Madrid Fusión, one of the largest and oldest international gastronomy conventions. Andoni Luis Aduriz, chef and owner of the renowned Spanish  restaurant Mugaritz, spoke with Redzepi.

Redzepi says there’s been a “flavor spread” or “quality spread” of gastronomy techniques. He points to espumas, the Spanish term for culinary foaming. – now used on every continent, in every level of restaurant. A gourmet dish may come from the neighborhood brasserie, a tapas bar or even a food truck. It’s “dramatically changed” the restaurant industry, he notes.

“That’s because people don’t understand the influence and the philosophies that [are] now completely naturalized in every corner of gastronomy,” he says.  Techniques once used only in premier establishments have become part of cooking DNA. “I hope fermentation will be that because I genuinely believe in the power of that.”

When Noma opened in November 2003, Redzepi promised Nordic cuisine made with local produce. But it was winter and freezing, making sourcing food a challenge, “so I stepped into the wilderness to find flavors.” 

He also realized Noma needed to conserve summer produce for the long winter. 

“We started to use pickling, fermentation, drying, smoking. Twenty years later, we have this bank of knowledge,” he said. “Before, we used to try 20,000 different fermentation techniques, now we are trying one at a time, with the whole team, like we are doing with lacto-fermentation.”

Fermentation drives an enormous amount of innovation at Noma. Redzepi told the Madrid Fusion audience that the restaurant industry is one of the most difficult to work in, so innovation and experience are what drive profitability.

“That’s what makes it special, putting together a team, while constantly looking for the ‘next big thing,’” he says. “That’s where the challenge is; pushing yourself outside of your comfort zone, until you have no clue what you’re doing, but as a group, you draw on your experiences, you trust each other, and you dare to move onwards.” 

Redzepi praised the current state of Spain’s cuisine, saying “the Spanish influence is a natural part of any fine dining kitchen in the Western world.”When he was starting out in the 90s, French food was the only focus for chefs. “You were going to cook French food in Denmark, that’s what I always thought to myself.” But when he took a job cooking in Spain for a season, “it was like everything that you had been taught before, all your rules that you knew, were sort of thrown away and you could build and dream in a different way. “[Spanish cuisine] has given me the very seed of everything that’s become Noma.”

The United States is becoming more diverse, with 4 of every 10 Americans identifying as non-white. But grocery stores have been a poor reflection of that mix of cultures. Now, a group of BIPOC food entrepreneurs are encouraging buyers and retailers to expand the range of products featured on store shelves.

“It has to start with leadership at the top saying, ‘We have to champion emerging brands because it’s good business,’” says Clara Paye, founder of UNiTE Foods, a maker of protein bars with international flavors. “Let’s face it. Your customers are diverse. They’re looking for diverse products. Create the incentive structures for buyers out there to have those placements and do it confidently.”

Paye was part of a panel at Natural Products Expo West discussing the challenges and opportunities for founders of color. The U.S. food system, the panelists lamented, is far from equitable. For example, though foods like kimchi and miso are staples in Asian countries, shoppers are hard-pressed to find a broad and deep array of multicultural food products at a typical American grocery.

“There wasn’t an avenue if you weren’t born and raised in America,” Paye explains.

Reclaiming Food Culture

The panel stressed that they could never find the traditional foods they ate growing up when they went to American grocery stores. First- and second-generation immigrants have never been the focus of major retail food brands. Underserved in this way, these BIPOC founders say they started their companies to reconnect with the flavors of their cultures.

“We felt it was a travesty that the second largest continent in the world [Africa] didn’t have any reflection in mainstream grocery,” says Perteet Spencer, founder of Ayo Foods, which sells West African frozen dishes and jarred sauces. (Spencer — a former employee of SPINS, a retail sales data provider for natural products — spoke at a TFA webinar in 2021). 

But she notes the food system is changing: “It’s clear that the market has shifted over the last several years and is embracing global flavors.”

Expanding the flavor of Mexican cuisine is the goal of Miguel Leal, co-founder and CEO of Somos, maker of Mexican meal kits.

“There’s stereotypically this (belief) that ethnic food has to be cheap,” he says. “It can be beautiful or clean or premium.”

Vanessa Pham agrees, adding there’s a narrative that authentic ethnic food should only be served in hole-in-the-wall restaurants. Pham is co-founder of Omsom, which makes chef-created Asian dishes. “Authentic” is a complicated term, she says.

“Authenticity sometimes pegs and limits food founders and chefs to a nostalgic idea, ‘How my grandma made it’ or ‘The traditional way,’” she explains. “We believe BIPOC chefs should be able to innovate. Cultural integrity is much more about doing your research, involving the right people and compensating ethically.”

Ethnic Aisle: Integrate or Celebrate? 

The ethnic aisle in groceries is a debated topic among BIPOC food leaders. Some say it’s an easy way for shoppers to find international products; others argue it’s an antiquated and offensive placement.

“I like the ethnic aisle, I just don’t like the way it’s showing us today,” Leal says. “It’s a little bit of a caricature.”

A recent survey by Adobe found 66% of African Americans and 53% of Latinos feel their ethnicity is portrayed stereotypically in food advertisements.

Pham views a future where the hodgepodge of products in the ethnic aisle disappears, and rice noodles are sold next to spaghetti. Paye agrees. “I think it will be a thing of the past, a funny thing where we put candles and beans and matzo balls.”.

Berryland, an award-winning Ukranian cider and mead producer, was destroyed by a bomb in a Russian air raid. The employees escaped and were uninjured.

Owner and oenologist Vitalli Karvyha built his facility six years ago in the Makariv District of Kyiv. Karvyha makes his ciders and meads from local fruits and berries, and raised bees on site for the honey for his mead. His fermented beverages have earned him awards at Vintage Cider World in Germany and the Mazer Cup in Colorado.

Karvyha says he plans to rebuild, updating his status through Berryland Cidery’s Facebook page.

Further catapulting fermentation into the culinary zeitgeist: Sandor Katz was a guest on the Rachael Ray Show, talking about fermentation and sharing a homemade sauerkraut recipe. 

“Everybody eats and drinks products of fermentation everyday,” Katz said on the show’s March 8 episode. “Fermentation, which is the transformation action of microorganisms, is so integral to how we make effective use of whatever food resources are available to us.”

Katz, author of six books on fermentation, stressed “bread is fermented, cheese is fermented, cured meats are fermented, condiments are either directly fermented or they rely on vinegar, which is a direct product of fermentation.” 

Katz demonstrated how to make a sauerkraut for viewers, encouraging them: “Don’t be intimidated by fermentation.”

In a food industry where greenwashing is common, Local Culture Live Ferments doesn’t pad their sales sheets with environmental fluff. Sustainability is core to their business practices.

“I never want to stray away from the connections with our farmers. I never want to stray away from the quality of our ferments,” says Chris Frost-McKee, director of operations for the Northern California-based vegetable fermenter. Sauerkraut is their top seller. “We take a lot of pride from the fact that we don’t ferment in plastic. We are doing our part to be as plastic-free as possible and leave the smallest footprint that we can.”

The company began as a passion project of Chris’ sister, Sarah. She recruited her brother, a home fermenter since his early 20s, and they envisioned creating two Local Culture fermentation hubs on the west coast — one where Sarah lives, in Bend, Ore., and a second in Grass Valley, Calif., Chris’ home. True to their name, they wanted to ferment with local produce. But, with the colder climate in Central Oregon cutting Bend’s growing season short, this proved impossible. 

“In Grass Valley, we’re able to source cabbage eight miles from our facility, eight months out of the year. We’ve created partnerships where every year the farm is planting more and more acreage for us, rotating their cover crops. It’s a beautiful thing, it’s real regenerative farming,” Chris says. And Sarah is now creating a separate project, fermented salad dressings, under the Super Belly Ferments brand.

Local Culture started as a farmers market side hustle, but Chris and his business partners (wife Cristina and friend Elissa Wolf Blank, pictured with Chris) dove into scaling the business in 2020. They’re now in over 100 grocers in the west, including Whole Foods. Though sales boomed during the pandemic, 2022 is shaping to be their biggest year. At the recent Expo West, Local Culture was one of 40 brands selected by food distributor KeHe for the exclusive “Golden Ticket” at their TrendFinder Event This designation fast-tracks small businesses into KeHe’s product portfolio, giving them exposure to over 30,000 retail locations.

Below is a Q&A with Chris Frost-McKee, who spoke with The Fermentation Association on the Expo West show floor.

TFA: Congrats on the KeHe “Golden Ticket” win! What are you going to have to change about scaling?

Chris Frost-McKee: The tricky thing with scaling the way that we do, our fermenters are stainless steel, variable capacity fermenters. We currently have 66 of them. We’ll need to get more as we scale, but they’re only sold once a year during wine making season. They ship them over from Italy. So that presents difficulties for sure. Producing in the same size fermenters, that’s part of the integrity we’re going to keep, that’s very important to me. We ferment for a minimum of 4-6 weeks in a very regulated, temperature-controlled environment. That really helps with the consistency of our product. 

We are also keeping the values the same with our farmers, making sure they can scale while staying sustainable. We’re scaling up our acreage with our main farmer next year. They rotate three successions of a summer variety of cabbage for us and then one succession of winter storage. And with those four successions, we can work about eight months directly with them, never going into cold storage. 

You just returned from a planning meeting with the local farm that supplies your cabbage. Tell me more about the farmers you work with.

CFM: We’re trying to only work farmer direct. One of our closest connections is the farm Super Tuber. They are Nevada City-based. They focus on regenerative farming practices and they focus on staple root crops and cabbage. So from the very beginning, as we first started with these smaller products, we started buying cabbage from them. Twice a year we sit down with them with the planting planning: What do you think it’s going to look like this year? How many plugs on your side can you plant for us? 

Super Tuber is really into this idea and I love it — they harvest in reusable bins in the field, then bring them straight to us in reusable bins. When you work with farms, produce comes in paraffin or wax boxes. Those go straight in the landfill. We are trying to have as little waste as possible. We’d love to never receive anything in wax boxes, and we’re there about 95% of the time. We compost everything that comes out of the kitchen.

Another thing, the cabbage isn’t wrapped in plastic packaging. We peel off the outer cabbage leaves as we prep in the kitchen. Those outer leaves are what I like to layer on top to seal everything. It weighs the ferment batch down and provides a nice layer if there’s ever an impurity — which really doesn’t happen — so if we ever discard anything, it’s those top leaves that would normally get composted. 

What was the biggest turning point for your brand to go from selling at farmer markets to getting in stores?

CFM: Honestly, as corporate as Whole Foods is, they have a wonderful way of supporting small brands. The west coast is filled with small ferment companies trying so hard and not succeeding at getting in. Whole Foods saw potential in us. That was really the turning point for our company. And they’ve continued to be loyal to us. Not all chains are pleasant to work with, but we made big moves through Whole Foods. It opened up this door to the Bay Area independents, like the Good Food Mercantile and the Good Food Awards. The Bay Area independents are so cutting edge in a way that I think a lot of these big chains strive to be as far as the products that they bring in and the diversity they really search for in craft products. At this point, we’re almost everywhere in the greater Bay Area that we’ve set out to be in — and I do think that started with getting in Whole Foods in 2020.

TFA: How were you distributing before that?

CFM: We were driving all over Northern California. We would drive five hours round trip to drop off like 10 cases of kraut. It did not make sense long term. Now we work with Tony’s Fine Foods to distribute to the pacific region. Tony’s has been supportive from the beginning. 

We still self distribute locally, but only whatever we can do in a 20 minutes drive. The local support that we have, that started with our stands at the farmers market and then our storefront, that support has been amazing. Like we honestly sell more in our local co-op then we do in 40 stores in the Pacific Northwest. That kind of local support will always be there.

TFA: That’s great that you have a big local fan base.

CFM: When we decided to get going in Grass Valley, we opened up a store front for a year-and-a-half and had this really great interface with our community. We were really experimental in those years. That was the year I was coming up with a lot of small batches. When we were invited to be in the Whole Foods, we had to move to a distributor and palletize. Things were not so small batch anymore. Right as the pandemic hit, we started being received really well in the west coast. We streamlined the products that people really wanted. We’ve got our favorite line of krauts, our different kimchis. We still do a lot of hot sauces and brine tonics. 

TFA: What is your favorite flavor?

CFM: Turmeric Ginger Jalapeno is my go-to, everyday. My body craves it. Our Beet Fennel though outsells anything we carry. People love it.

TFA: You’ve gone from fermenting in your home kitchen to distributing regionally. What do you think has been your biggest lesson in all of this?

CFM: Not giving up. Listening to the ferments — it sounds really weird, but I literally have studied patterns in the life within the fermenters. For example, we have these variable capacity lids that have an airlock on the top where the brine can spit out. In certain ebbs and flows, I think it’s astrological, all the fermenters will come to life, no matter how old they are. Or in a certain cycle of the moon, all of them will compact and leave an air pocket that I have to reset. It is crazy, witnessing the nature and patterns.

Through all the trial and error and discouragement, it’s the life of the microbiology itself that is really the inspiring thing. I could never get it right, it’s always going to be different no matter what. But I’m getting a lot better at creating that perfect environment for consistency. If you ask me — I’m living and breathing it because I digest this all the time.

TFA: Where do you see the future of fermentation?

CFM: I see it growing. It is beyond all the trends, it’s something that’s been around for ages, for centuries, and there’s a reason why it’s always been incorporated in our diets. There’s this sense of awakening that so many people in the mainstream are feeling — if it’s kombucha, if it’s sauerkraut, if it’s kefir, if it’s yogurt — people are really feeling the benefits. The pandemic has had a huge influence on that, too. I think everyone in grocery would agree fermentation is a big thing right now and it deserves to be a big thing. 

Big food companies are “eager to tap into the magic of fermentation,” says chef David Zilber. They’re hungry to hire culinary  experts who can use fermentation to enhance existing products or mold the flavor profiles of new ones.

“These big companies are all waking up to the trend of fermentation and it is on us, on anyone who understands this craft intimately, to be the ones to engage them and guide them towards better solutions,” Zilber said at KojiCon. Fermenters could go the traditional route and open a local  shop to feed a small number of people. But “there’s also a lot to be said for working within an existing system and fermenting the change you want to eat in the world. The biggest food producers in the world are responsible for nourishing most of mankind.”

The former head of the Noma fermentation lab, Zilber co-authored The Noma Guide to Fermentation with Noma’s founder Rene Redzepi. In the fall of 2020, Zilber surprised the food world when he left his job at Noma to join Chr. Hansen, a global supplier of bioscience ingredients.

Zilber said he understands the push-and-pull between working in traditional fermentation vs. large-scale food production. Though he cherished his time at Noma, he realized fine dining is “a minuscule fraction of the amount of food people eat” and, if he wanted to influence any big change in the food industry, he needed to move away from restaurants. He compared it to being “the punk rocker that rails against the system” when instead “subverting it from the inside is an amazing way to effect change extremely quickly.”

“When you learn to speak bacteria or when you learn to speak fungus, the hardcore food scientists don’t have this intuition,” he continues. “They grow these things in petri dishes and with colony pickers in €20,000  machines. It’s not the same thing, and we are a little bit at a watershed moment where there is enough community knowledge…that we can start to broach these players and try and change it.”

Streaming into KojiCon from his state-of-the-art kitchen at Chr. Hansen’s Copenhagen headquarters, Zilber shared his latest project: a tomato sauce for a client, improved through fermentation. In his kitchen, he works with chefs and food companies to use fermentation to develop healthier and more sustainable products. Holding up a sample of tomato sauce to the KojiCon attendees, Zilber shared how he was able to amplify the flavor profile of the canned tomato sauce using fermentation. He eliminated added white sugar and created a flavor with hints of parmesan cheese. 

“We haven’t added anything but a culture onto it,” he said. “At the end of the day, should this tomato sauce go into production, millions of people overnight will be eating a tastier, probiotic (filled), more nutritious food on their pasta. And I never had to teach them how to lacto-ferment a single thing.”

Chr. Hansen is building one of the largest collections of cultures in the world, currently totalling 40,000 specimens. Zilber describes it as a seed bank, “the Noah’s Ark of Life for microbial diversity.” Chr. Hansen works with companies to select the optimal culture for their food item.

Smaller-scale producers, too, purchase cultures, often to mitigate risk. A fermentation mistake in a one-ton batch of kimchi could destroy thousands of dollars worth of product. Using a guaranteed culture strain will allow them to produce kimchi of consistent quality. But Zilber acknowledges there is no wild fermentation, no son-mat – a common phrase in Korean cooking that literally translates to “the taste of one’s hands.”

“There are aspects of the world of fermentation that are decidedly unwild, there are aspects of the world of fermentation that are nothing but wild,” he says. 

Zilber believes we’re in the era of the democratization of fermentation, where books and educational courses are teaching the public about fermentation. He mentioned the new Sex and the City reboot featured a scene where a character was angry that sourdough challah was “too hipster.”

“It’s funny that it’s permeated public consciousness that much where we can now make jokes about it in multi-million-dollar, prime-time television shows. It means that the idea of fermentation in that respect has reached fixation. The world has woken up to this.”

Noma launched their direct-to-consumer food products line in February with a smoked mushroom garum. Their vegan spin on a traditional fermented fish sauce is the first release from Noma Projects, the famed restaurant’s product line for home cooks. That garum, retailing for $24 per 250cl bottle, sold out in a day.

“At Noma they’ve turned to koji and mushrooms instead of fermented fish to create their umami-rich smoked mushroom garum. It’s not as intensely salty as some other garum-adjacent products, and the aroma and flavor reveal subtle smoke and mushrooms,” writes Florence Fabricant of The New York Times

Noma Projects — which launched last year — will include more pantry projects and community-based initiatives in the future, said René Redzepi, chef and co-owner of the Copenhagen-based restaurant. He hopes Noma Projects will him make more money. Noma has hovered around a slim 3% profit margin ever since opening 18 years ago.

Racist and sexist comments have long been hurled at food companies run by Asian American women. But in the modern tech era, where food brands have a social media presence, these cruel remarks from trolls are being dealt with in a variety of ways. Some fight back with humor, others aim to educate while some ignore it.

Kim Pham, co-founder (with her sister Vanessa) of Omsom (which sells Asian pantry staples), said it was difficult in the brand’s early days for her to read offensive comments. She came to a sad realization: “I think it’s par for the course when you are an outspoken brand run by women of color.” 

“For so long our community has been defined by this model minority myth, of being quiet, or docile, or submissive,” said Pham, “and we really just wanted to give a middle finger to that.”

Omsom’s social media policy is to remove insulting comments, but leave anything that “might generate a fruitful conversation.” 

Jing Gao of Fly By Jing (which sells Asian pantry staples, dumplings and hot pots) (pictured), though, takes a different approach. “We have no problem making fun of those people who are, you know, clearly disturbed,” said Jing Gao, the company’s 34-year-old founder, adding “We definitely troll them. … and our community seems to really love it.”

Meanwhile Sahra Nguyen, founder of Nguyen Coffee Supply, has zero tolerance for trolls. She doesn’t want her employees engaging in toxic behavior, so they don’t respond.
