Zack and Ray sit down with AJ Kim of Kumquat Coffee to talk about the green side of home roasting. They dig into how Kumquat, Loquat, and Fondry grew into an ecosystem for serious home brewers and roasters, and why AJ started a curated green-coffee shop for small batches. Along the way, AJ shares what he’s learned visiting producers around the world and why understanding farms, pricing, and climate risk should change how we buy and roast coffee at home.

Zack and Ray kick things off breaking down the global matcha shortage and debating whether Tokyo is the best coffee city in the world. Then they sit down with Masa of Weekenders Coffee (Kyoto) to talk about Japan’s evolving café culture, light-roast philosophy, and Weekenders’ new 20th-anniversary collaboration box.

Home roasting is exploding—and it’s no longer just for pros. Ray and Zack dive into the rise of the home-roasting movement with guest Robert Asami, a hobbyist roaster from the Bay Area. They unpack ultra-light roasts, the new tech driving the scene (Roest, Nucleus Link, Kaffelogic), and the growing culture of experimentation, education, and gear obsession.

Lance from Sey Coffee joins us to talk: co-ferments, “rock-star” producers, trends, the real work of sourcing, doing the reps (cupping daily), why clean 87–90pt washed lots are miracles, pricing/value (cost-per-cup), curation and seasonality, and how roasters can truly stand out in 2025.

In the debut Drank it! episode, Ray Murakawa and Zack Stamey debate overpriced, under-extracted pour-overs, by-the-cup relevance in 2025, and why hospitality still wins.
