Overview
The Fellow Aiden Espresso Pro builds on the Opus platform with enhanced features for the more demanding home barista. An upgraded thermoblock with dual-path heating provides faster recovery between shots and the ability to switch to steam mode in under 5 seconds. The PID controller offers temperature adjustment in 0.5-degree increments with a clean OLED display. The 58mm group head features an improved shower screen design that promotes more even water distribution across the coffee puck. Programmable pre-infusion allows users to set both pressure and duration. The steam wand is lengthened compared to the Opus, accommodating larger pitchers for latte art practice. Fellow's signature design language continues with premium materials and a visual identity that would look at home on a design studio desk. The machine includes Fellow's app connectivity for recipe storage and firmware updates. The Aiden Pro targets intermediate baristas upgrading from entry-level machines who value both aesthetic design and extraction quality — the same audience that made Fellow's pour-over products bestsellers.
The Fellow Aiden Espresso Pro 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 15.0 bars of pressure for optimal extraction.
Priced at $599, the Fellow Aiden Espresso Pro 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 Fellow Aiden Espresso Pro is a substantial machine, weighing in at 8.0 kg, manufactured in USA, drawing 1500W of power. With dimensions of 280 x 400 x 350 mm (W×D×H), make sure you have adequate counter space. The built-in water reservoir holds 1800 ml, making it easy to set up anywhere in your kitchen.
