The ultimate barista's tool.
Hand-built espresso machines designed around flow rate control, pressure profiling and absolute temperature stability.
Why baristas choose Slayer.
Patented needle valve
Slayer's defining technology. Restricting water flow rate lets you grind finer and shape the extraction — a pre-brew phase that saturates the bed gently before full flow.
Independent tanks per group
Every group has its own brew tank with PID control, plus a dedicated steam tank. Pull and steam simultaneously without pressure drops or temperature loss.
Handcrafted in Seattle
Seattle Espresso Machine Corporation builds each machine by hand in Renton, Washington. Wood, panel colour and metal finishes are configurable to your bar.
Built for the bar
Low profile for customer engagement, shot mirrors, big adjustable drip trays, and modular parts that keep long-term maintenance cost down.
Six ways to build your bar.
- Patented needle valve for restricted flow rate — grind finer, profile flavor
- 3-position brew actuator rated at 1 million cycles
- Programmable pre-brew timer
- Supplemental pre-heat tank for near-infinite temperature-stable water
- Handcrafted and fully customizable wood, panel and metal finishes
Espresso v3
Flow rate control via patented Needle Valve technology lets the barista extract espresso that is unparalleled in flavor and mouthfeel. An independent brew tank per group delivers impeccable temperature stability, while a dedicated steam tank gives unlimited steam capacity.
