Real Pickles Partners with UMass Scientists to Study Facility Microbiome

AMHERST, Mass. – University of Massachusetts Amherst food scientists have mapped and characterized microbial populations at Real Pickles’ facility and report that its microbiome was distinct between production and fermentation areas and that the raw vegetables themselves – cabbages destined for sauerkraut – were the main source of fermentation-related microbes in production areas rather than handling or other environmental sources. 

Writing in Applied and Environmental Microbiology, scientists in Dr. David Sela’s lab at UMass Amherst, in collaboration with scientists from two units of the U.S. Food and Drug Administration’s Center for Food Safety and Applied Nutrition, say this study helps to resolve the question of how microbes are transferred within a food fermentation production facility.

Real Pickles is a worker-owned cooperative in Greenfield, Mass. and makes pickles, sauerkraut, and other fermented vegetables the old-fashioned way, by natural fermentation and without starter cultures or inoculants. Nutritional microbiologist Sela notes that very little is known about the microbiomes of these facilities. Fermented foods are increasingly popular internationally, he adds, because of their enhanced nutritional properties, cultural history and flavor, so the new information from this study should be of interest to food scientists, microbiologists and manufacturers around the world.

Company founder Dan Rosenberg says, “It’s fascinating to learn about the influence of fresh vegetables in establishing our facility’s microbiome and suggests that our use of organic vegetables is important to contributing a diverse microbial community to support a vigorous fermentation. It raises interesting questions about how we can further improve our production practices to be producing fermented and probiotic foods of the highest quality.”

The scientists used a state-of-the-art genomics approach to identify microbial species present instead of culturing the microbes. This allowed the team to quickly identify more microbes than conventional methods, to estimate their relative numbers, predict their function and determine the flow of microbes into and within the facility.

Sela adds, “For the first time, we built a map of the facility and how it was transformed over time during fermentation, which has given us a more complete picture of the population in a real vegetable fermentation facility. Both cheese and beer have been done to a certain extent, but we feel that fermented vegetable facilities could be better characterized. And because we are using these new genomic tools, we have a better understanding of what is there and how they got there. Using the traditional approach, we couldn’t possibly culture everything, so we’d have a far more limited picture.”

“There is so much still to learn about fermented foods, nutrition, and the human gut microbiome – we are excited to be a part of the science exploring these important questions,” says Rosenberg.

This work was funded in part by the Center for Produce Safety, and undergraduate fellowships from the American Society for Microbiology, the UMass Amherst Commonwealth Honors College and the UMass Amherst Center for Agriculture, Food, and the Environment.

Thank you to all who attended and worked at our 2025 Strawberry Ice Cream Social Fundraiser. It was a wonderful evening on June 12th at our Easthampton store, celebrating the start of the local summer harvest season and supporting the Center for New Americans. Nearly 800 people attended this patio party throughout the evening, purchasing burgers, grilled corn on the cob, salads, and Strawberry Ice Cream Sundaes. This resulted in raising a total of $10,953 for the Center for New Americans. This is a record high for this fundraising patio party!
