Our Verdict
The Compak K3 Touch from Compak is a solid option in the upper mid-range grinder segment. Conical burrs are a popular choice for home espresso, offering good grind quality with generally lower noise and less heat buildup than flat burrs. The slightly bimodal grind distribution can produce espresso with more body and texture. Remember the golden rule: the grinder is at least as important as the espresso machine.

This grinder should serve you well for years of daily use and is a worthwhile investment in your espresso quality.
Frequently Asked Questions

Yes, the Compak K3 Touch is capable of grinding fine enough for espresso. Its stepless adjustment allows you to dial in precisely for any coffee.
How do the conical burrs in the Compak K3 Touch affect espresso?

Clean out retained grounds after each use with a brush or bellows. Deep clean the burrs every 2-4 weeks by removing them and brushing away oil buildup. For the motor, occasional use of grinder cleaning tablets (like Grindz) helps remove coffee oil buildup. Never wash burrs with water.
