Frequently Asked Questions
Common questions about this comparison
Which machine provides the ideal pressure for espresso extraction?
The Gaggia Classic Evo Pro is optimized for a consistent 9-bar extraction pressure, which is generally considered ideal for espresso. The Gemilai Owl features a 15-bar pump, but ideal extraction pressure is 9 bars.

The Gemilai Owl, with its PID temperature control, adjustable brewing parameters (temp, pre-infusion), and dual display, offers more real-time feedback and fine-tuning options. The Gaggia focuses on reliable, straightforward 9-bar extraction.
Do both machines use a standard portafilter size?
