Synesso S300

Overview

The Synesso S300 is a single-group commercial espresso machine from the Seattle-based manufacturer that has built a devoted following among specialty coffee professionals in North America and beyond. Founded by former La Marzocco technicians who wanted to push espresso technology further, Synesso designs and builds their machines in Seattle with an engineering philosophy that prioritizes thermal stability and extraction consistency above all else. The S300 features Synesso dual boiler system with individually PID-controlled brew and steam boilers, both constructed from surgical-grade stainless steel. The proprietary group head design maintains brew temperature within an extraordinarily tight tolerance — arguably the tightest in the industry — through a combination of active heating and insulated group design. Full pressure profiling capability allows complex extraction curves, and the S300 includes volumetric programming with manual override. The commercial rotary pump is vibration-isolated for quiet operation, and the machine requires plumbed water connection with direct drain. The build quality is exceptional — every component is designed for commercial durability, and the internal layout facilitates service access for maintenance. At 40 kilograms, the S300 is a substantial piece of engineering that demands a dedicated space and proper infrastructure. For the home enthusiast who wants genuine American commercial espresso engineering, or the micro-café owner who values Synesso precision, the S300 delivers uncompromising performance from a company that lives and breathes specialty coffee.

The Synesso S300 comes equipped with PID temperature control for precise brewing, pre-infusion for even extraction, pressure profiling for advanced shot manipulation, flow control for barista-level precision. It features a dual boiler boiler system made of stainless steel with a 600 ml capacity. The rotary pump delivers 9.0 bars of pressure for optimal extraction.

Priced at $7,500, the Synesso S300 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 Synesso S300 is a substantial machine, weighing in at 40.0 kg, manufactured in United States, drawing 2400W of power. With dimensions of 430 x 540 x 460 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.
