Overview
The Slayer Steam LP is the two-group workhorse of specialty cafes worldwide, combining Slayer's legendary needle valve technology with high-volume steam capability. The LP (Latte Performance) variant emphasizes steam power with a larger 3.8-liter steam boiler optimized for shops where milk drinks dominate the menu. Each group features independent temperature control and Slayer's signature pre-brew flow control that allows baristas to initiate extraction at sub-bar pressures before ramping to full pressure. The visual design is unmistakably Slayer — clean geometric lines, premium powder coat finish, and the distinctive raised group heads that have become iconic in third-wave coffee culture. Built entirely in Seattle with domestically sourced components where possible, each machine undergoes extensive quality testing before shipping. The Steam LP has become a status symbol for serious specialty cafes, signaling a commitment to extraction quality that coffee enthusiasts recognize instantly. At its price point, it competes with La Marzocco Strada and Victoria Arduino Eagle One.
The Slayer Steam LP comes equipped with PID temperature control for precise brewing, pre-infusion for even extraction, flow control for barista-level precision. It features a dual boiler boiler system made of copper with a 400 ml capacity. The rotary pump delivers 9.0 bars of pressure for optimal extraction.
Priced at $16,500, the Slayer Steam LP is designed for passionate enthusiasts and semi-commercial users who accept nothing but the best. As a semi-automatic machine, it gives you control over the brewing process while handling pressure and temperature automatically.
In terms of build quality, the Slayer Steam LP is a substantial machine, weighing in at 68.0 kg, manufactured in USA, drawing 4800W of power. With dimensions of 762 x 559 x 445 mm (W×D×H), make sure you have adequate counter space. This machine requires direct plumbing, which provides unlimited water supply but needs professional installation.
