Something fresh
is brewing.

GYST is evolving. We're more than just a neighborhood fermentation bar – we're a creative food business. We're exploring new ideas of how food can impact our lives and communities.


GYST: (n) simple; the essence; old english
word for yeast


GYST pairs experience with expertise. Our work is dedicated to  people to living their best and most creative lives through fermented food and drink.  Whether it be in the company of community or one's own personal journey, let us guide you back to all things simple, natural, healthy and happy. We believe the "gyst" of life is to enjoy and delight in each and every day. Join us!

Founding Sisters

Two Sisters. One GYST.

The sisters are intensely passionate about highlighting the love and effort that winemakers, cheese mongers, and farmers all over the world put into their products. GYST, a product of that same love and effort, has become a community hub – sharing knowledge, history, and the ancient art of fermentation through classes, events, and local partnerships as well as simple, healthy food and drink.
