Welcome to Proof of Concept, the official podcast of The Tasting Alliance — the team behind the world’s most prestigious spirits competitions, including the San Francisco World Spirits Competition, New York World Spirits Competition, Asia World Spirits Competition, and Latin America World Spirits Competition. Hosted by Toby Blue, Chairman and Chief Operating Officer of The Tasting Alliance and longtime spirits industry executive and Jason Rabinowitz, Multiple Grammy Award Nominee and Entertainment Industry Veteran, this series explores the journeys behind the world’s most exceptional Double Gold–winning spirits — and the founders bold enough to build them. At its core, Proof of Concept is about entrepreneurship, craftsmanship, innovation and resilience. Each episode dives deep into the stories of founders, distillers, master blenders and visionaries who transformed an idea into an award-winning spirit — validated under the most rigorous blind tasting standards in the world. Proof as potency. Proof as validation. Proof that an idea can work. This podcast is where passion meets purpose, and where brand building, storytelling, sustainability, leadership and legacy intersect in the glass. From Idea to Icon. From Grain to Glass to Gold.
