Fellow spent a decade perfecting kettles, grinders, and brewers before building an espresso machine, and the Series 1 makes clear the wait was worth it. At the heart of it is a patented Boosted Boiler system with three independent heating elements delivering precise temperature stability and a warm-up time of under two minutes. The commercial-style 58mm group head has a brass core and water dispersion block for even extraction, while adaptive pressure profiling adjusts flow automatically to hit your pressure and time targets. Dial in temperature, pressure, and flow, save your profiles, and repeat them shot for shot. The steam wand senses temperature, auto-stops, and self-purges after each use. Three colorways, matching wood-accented accessories, and a companion app round out the package. Everything you'd expect from a Fellow product, now in espresso form.
