Fermentation Fest is produced by Wormfarm Institute, who are a nationally recognized leader in catalyzing cross sector partnerships, which celebrate the culture in agriculture. While free public events such as the Farm/Art DTour—the signature element of Fermentation Fest—reach thousands, they are not cost-free and rely upon grants, sponsorships and individual donations from folks like you. Please consider a tax-deductible gift today.
