In this episode of Proof of Concept, hosts Toby Blue and Jason Rabinowitz speak with Judah Kuper, co-founder of Mezcal Vago, about the journey behind one of the world’s most respected artisanal mezcal brands. Built on deep relationships with generational mezcaleros, Mezcal Vago is known for radical transparency — crediting each batch to the maestro who made it and documenting every detail from agave species to fermentation and distillation methods. Judah shares how the brand’s philosophy, “Don’t kill the magic,” guides their approach to growth, sustainability, and sharing mezcal with a global audience while protecting its cultural roots. The conversation explores the delicate balance between tradition and scale, the pride and recognition that international awards have brought to Oaxaca’s palenques, and what it means to build a spirits brand that uplifts the people and communities behind the craft.
