Celebrate all things fermented at the sixth annual Boston Fermentation Festival at the Boston Public Market today from 10 a.m. until 4 p.m. Listen to talks from farmers, authors, and food historians about the science, process, and popularity of fermentation. Sample pickles, kimchi, kombucha, sour beer, and other fermented treats from local and regional artisans at the Makers Marketplace. While you’re at the marketplace, pick up some of your favorite foods and drinks to take home.

If you want to try your hand at making your own fermented food, join the Kraut Mobs in a kraut-making workshop. Prepare by reviewing these steps on how to make your own sauerkraut masterpiece. Workshops are underway all day.

For cooks already into making fermented food and drinks, you can swap cultures with others.

Admission to the festival is free.

The Boston Public Market is located at 100 Hanover Street, directly above the Haymarket Station, which is served by the Orange and Green Lines and several buses. If you’re taking Amtrak or the commuter rail, get off at North Station and walk three blocks to the market. Plan your trip on the T.
