    John Griffith - CEO & Partner

    Hailing from Virginia, Griff’s love for the world of microbiology began during his tenure at Colorado State University. Intent on becoming a veterinarian, his pursuits led him through several research labs studying a broad array of areas including infectious diseases, antimicrobials, invasive weeds, and statistics. He ultimately decided to focus his efforts on the far more noble vocation of kombucha brewing. After relocating to Bozeman, his casual search for a starter culture turned into time spent developing the nascent brewery’s lab environment and quality control practices. Griff picked up the mantle of brewery operations and never looked back. His days are now spent helping launch innovative products and guiding brand strategy for Zesty Beverages. Outside of Zesty, he is a passionate musician and dog lover.
