Our Mission

Koast Kombucha is a premium, handcrafted, probiotic beverage founded in San Francisco in 2015. Our love for the coast has inspired us to create a drink that sets the golden standard for kombucha, and we pride ourselves on quality craftsmanship using time-tested materials and techniques to bring you a unique experience you won't find anywhere else.

The Koast Team, San Francisco 2024

Each flavor is inspired by the beautiful California Coast with a focus on taste and quality. Our products are handcrafted in our kitchen in San Francisco, and each batch is aged in oak barrels, creating a unique flavor profile that's packed with healthy probiotics, beneficial acids, and vitamins promoting a healthy gut. We made it simple so you can focus on the more important things in life.
