In this episode, we sit down with Harry (aka Kimoi Coffee Harry) of Moonwake Coffee to dive deep into modern specialty coffee—from hyper-dialed pour-over brewing and grinder burr theory to green buying, roast development, and water chemistry. Harry shares his journey from passionate home enthusiast to shaping Moonwake’s brewing program and green sourcing, including how ultra-high-end gear ended up at a farmers market. The conversation explores what “ultralight” coffee really means today, why water might matter more than your grinder, and how community and calibration drive better coffee more than chasing the next piece of gear.

Fused Visions creator Mehrdad joins Zack Stamey (Roastful) and Ray Murakawa (Melodrip) for a wide-ranging, unscripted conversation about coffee innovation, product design, and why collaboration matters more than hype. They dig into what makers get wrong (and right), the copycat problem, and how tools like slow-feeding and “dose by volume” can make espresso more consistent with less waste. Plus: rapid-fire takes on burr size, V60s, co-ferments, and whether cafés really need Rolls-Royce espresso machines.
