Comparison test - coffee grinders with impact grinder

For many, freshly grinding coffee beans is already part of a regular morning ritual; others, however, still shy away from the work and time involved. Yet true coffee enthusiasts have always relied on grinding their own coffee beans immediately before brewing. While whole coffee beans can retain their aroma for a month or two after roasting, the situation is completely different with ground coffee: After just a few minutes, it loses its aroma due to contact with oxygen. ETM TESTMAGAZIN tested electric coffee grinders for you, including ten grinders with cone grinders, four grinders with disc grinders and four grinders with impact grinders.
