Frequently Asked Questions
Common questions about this comparison
Which machine is better for making multiple milk-based drinks quickly?
The COWSAR is superior for efficiency with its dual boiler, allowing you to brew espresso and steam milk simultaneously. The Gemilai's thermoblock requires cycling between functions, slowing down the process for multiple lattes or cappuccinos.
What's the main difference in pump pressure?
The COWSAR features a 9-bar pump, often considered ideal for optimal espresso extraction. The Gemilai uses a 15-bar ULKA pump, which provides powerful pressure but typically requires a pressure reducer to hit the ideal 9 bars at the puck for brewing.
Is the price difference between the two machines worth it?
The COWSAR is about $40 more, but includes an integrated grinder and a dual boiler system, which are significant upgrades for convenience and simultaneous operation. For an all-in-one setup, the COWSAR offers excellent value for the price difference.
Which machine offers more control over the brewing process?
The Gemilai provides more explicit control with its dual display showing real-time pressure, temperature, and time, plus adjustable brewing parameters and a commercial 58mm portafilter. The COWSAR simplifies the process with its integrated grinder.
