Slayer espresso machines for hands-on flow control
Slayer machines are made by Seattle Espresso Machine Corporation in Washington State, and the brand has a clear idea of how espresso should be made: split the extraction into stages and adjust the flow of water to bring out sweetness. The V4 single group puts that thinking into a compact, commercial-style body.
Flow profiling you control
The V4 has a variable flow rate with both manual and semi-automatic modes. Instead of accepting one fixed flow from the pump, you decide how the water reaches the coffee through the shot. That lets you tune a coffee to its roast and origin, and it is a big part of why dialling in on a Slayer is so rewarding. Pair it with a good grinder and small changes in flow show up clearly in the cup.
Built for stable brewing
A double boiler system with PID temperature control keeps the brew temperature adjustable and steady, and a pre-heat coil and saturated brew group help with consistency from one shot to the next. A rotary pump, a lever steam valve and a glass touchscreen sit alongside European ash wood handles and actuators. The 58mm commercial portafilter takes an 18g basket.
Installation notes
The V4 connects directly to mains water, so plan for a plumbed water line and suitable water filtration before it arrives. Measure your bench and leave room above and around the machine for access, and talk to us about power requirements for your site.
