Visit wormfarminstitute.org to learn about Fermentation Fest 2022

Fermentation Fest: Grassland Edition (Sep 25-26, 2021) was a two-day celebration of live culture in all its forms, organized by Wormfarm Institute and researchers at Grassland 2.0 (University of Wisconsin–Madison) to showcase regenerative, grassland-based agriculture. Presented at the historic Witwen Park in Sauk County, WI, the fest included demos, art, performances from dance to “Grassical” music in an open-air Tabernacle to Scandinavian cow calling, local food, fermented beverages & more.


We invite both our rural and urban neighbors to take part in this polycultural rural revival!
