The Terroir line is roasted on a Ghibli profile roaster from Coffeetech, which is located in the Rösterei Kaffee und Bar next to the Blasercafé production hall. This allows batches of 15 kilograms to be roasted to profile. The roasting time and the roasting curve (temperature curve) can be defined according to the origin and variation of the beans using electronic control via the laptop. For example, coffees with a low degree of roasting have fruity, sweet and flowery notes, while coffees with a high degree of roasting have toasted, chocolate, caramel or clove flavours. The "terroir" aspects of a coffee are particularly pronounced in light roasts, which are particularly suitable for the preparation of filter coffee.
