About Us Marin Kombucha: Craft Brewed Kombucha That Transcends The Centuries.

Marin Kombucha is an exciting small local business that began operations in 2015. We happily brew and self-distribute the highest quality Kombucha, an ancient fermented and naturally carbonated tea, through wholesale supply to retail food stores, restaurants, bars and private companies.

CEO and Founder Brian Igersheim, with a Bachelor of Science degree and over 7 years of experience in the food and beverage industry, passionately applies his knowledge of biology and chemistry to create the alchemy of Marin Kombucha. Prior to founding Marin Kombucha, his focus was food safety/security, food industry quality control, and compliance while serving as the Director of Quality Control for the Maui Gold Pineapple Company on the island of Maui.

COO and Tea Master Gerit Williams has over 15 years of experience in the food, fermentation, and tea industry. Prior to beginning his career at Marin Kombucha, Gerit managed pickling operations for Maui Preserved, a small artisan pickle producer on the island of Maui. Sourcing the finest teas for Marin Kombucha, Gerit's guidance of brewing tea at its ideal time and temperature is integral to the unique palatablity of our oak-aged Kombucha tea.

We brew in small batches locally. Our philosophy is to deliver the most flavorful and competitively priced Kombucha available in Marin County and San Francisco. Now proudly serving the Chicago market as well.

Our brewing capacity is limited to 1500 gallons per week in order to maintain small batches throughout our fermentation process. We ensure the highest quality taste based on our streamlined brewing technique, quality control procedures, and unique flavors.
