About
Billy Dietz is co-founder of BDH Consultants, where he leads tea and beverage sourcing and product development for brands and co-packers across teabag, loose leaf, powder, and RTD formats. He brings over twenty years in the industry, starting at seventeen when he became the youngest Certified Tea Specialist in North America through the Specialty Tea Institute, later becoming a certified STI instructor. He continued his education with McCormick FONA and the Specialty Coffee Association of Europe. Nine years leading R&D at DAVIDsTEA gave him the technical depth to take clients from concept to shelf-ready product, on budget and matched to format. He's since worked with tea and beverage brands to build supplier networks, develop new product lines, and bring blends to market, work he distills in his 2023 book Spill the Tea: Unveiling the Mysteries of Blended, Flavored, and Herbal Teas, and in his Substack newsletter, Steep Insights.
