Espresso is Fellow's boldest chapter, built around the Series 1, the machine three years and a team of twenty-five engineers in the making. Around it sits the full workflow: the guided tamper and tamping mat for consistent pressure, the WDT tool and magnetic dosing funnel for clean puck prep, bottomless portafilters for reading your extraction, and the knock box that keeps the bench moving. Everything here is designed to work as one system, from the first dose to the spent puck.
