Frequently Asked Questions
Common questions about this comparison
What's the main difference in brewing components?
Both feature 15-bar pumps and thermoblock boilers. Chefman explicitly states a 58mm portafilter, a professional standard for better extraction. COWSAR mentions PID temperature control, which Chefman doesn't explicitly.
Which machine offers more control over grind size?
The Chefman Crema Supreme offers significantly more control with its integrated grinder providing 30 distinct grind settings. The COWSAR also includes a grinder but doesn't specify the number of settings, implying less versatility.
Which machine has a larger water reservoir?
The Chefman Crema Supreme has a larger 101.442 oz (3L) removable water tank. The COWSAR machine features a 75 oz removable water reservoir. Chefman's larger capacity means fewer refills.
Should I consider the COWSAR machine instead?
Yes, if PID temperature control is a high priority for consistent brewing. While both are large, COWSAR's 75oz reservoir might suit slightly smaller spaces or lower volume needs where constant refilling isn't an issue.
