Overview
The Petrus PE3606 is the brand's flagship home espresso machine, featuring PID temperature control and a robust 58mm group head that positions it as a serious contender against entry-level European prosumer machines. The large 2-liter reservoir and cup warmer tray suggest a machine designed for household with multiple daily espresso drinkers. PID maintains brew temperature within ±1°C, and the pre-infusion program is adjustable in duration. The commercial steam wand generates strong, dry steam suitable for texturing milk to microfoam quality. The PE3606 demonstrates how far Chinese espresso machine manufacturing has progressed, delivering specifications that would have been premium-tier features just a few years ago at a fraction of the expected cost.
The Petrus PE3606 comes equipped with PID temperature control for precise brewing, pre-infusion for even extraction. It features a thermoblock boiler system made of stainless steel. The vibratory pump delivers 20.0 bars of pressure for optimal extraction.
Priced at $320, the Petrus PE3606 is designed for home baristas looking for quality without breaking the bank. 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 Petrus PE3606 is a substantial machine, weighing in at 7.5 kg, manufactured in China, drawing 1500W of power. With dimensions of 310 x 300 x 360 mm (W×D×H), make sure you have adequate counter space. The built-in water reservoir holds 2000 ml, making it easy to set up anywhere in your kitchen.
