Unified Ferments

Unified Ferments is not a wine producer in the conventional sense, but it belongs firmly in the world of natural, low-intervention fermentation. Founded in Brooklyn in 2019, the project sits at the intersection of two ancient practices: exceptional tea cultivation and the transformative chemistry of fermentation. The result is a category of beverages that is neither kombucha nor tea but something genuinely new, and genuinely delicious.

Tea as the Primary Ingredient

Most people fermenting tea treat it as a medium for flavor modification. Unified Ferments reverses that assumption. Here, the tea is the star, and fermentation is the tool that unlocks its potential. The studio sources high-end and high-impact teas, from Taiwanese Wen Shan Bao Zhong to Japanese Soba and beyond, then uses kombucha fermentation techniques to create effervescent, non-alcoholic libations that translate the complexity of tea into a completely novel format.

Collaborations and Recognition

Unified Ferments has collaborated with Kettl, the Brooklyn-based Japanese tea importer, to produce a series of cuvees that fuse Japanese tea culture with American fermentation craft. The results have appeared on the tables of Eleven Madison Park, Four Horsemen, Atomix, Aska, and Kato, some of the most thoughtful beverage programs in the country. Coverage in Food and Wine, The Wall Street Journal, and Bon Appetit has followed.

Why It Belongs Here

Unified Ferments shares the values of natural wine: minimal intervention, whole ingredients, wild fermentation, an absolute commitment to the quality of the raw material. It is a project for the curious drinker, one who wants to understand what fermentation can do beyond the grape. For tables seeking brilliant non-alcoholic options that hold up alongside natural wine, there is nothing else quite like it.
