A lot happens in the roasting drum in just a few minutes: moisture escapes, sugar caramelizes, oils come to the surface. How quickly this happens ultimately determines the taste.

Time instead of heat

A long, moderately managed roast gives the bean time to fully develop its sugars. This creates sweetness and fullness without the beans burning on the outside and remaining raw on the inside. Short, very hot roasts, on the other hand, easily become bitter and harsh.

What this means in everyday life

Gently roasted coffee tastes less smoky, but rounder and often a little fruitier. It also forgives minor inaccuracies when brewing: a slowly roasted coffee still tastes good even if the water temperature is not exactly right.

How to tell

Whole beans from a gentle roast shine less intensely and feel drier. When pouring, a calm, fine-pored crema forms – a good sign that it has been roasted with patience.
