More individuality is not possible! More freshness neither! In Kater’s coffee roasting house, the raw coffee is gently roasted by traditional drum roasting procedures. Kater uses two roasting plants at up to 220 deg. C, and gives the coffee approx. 20 min. time to develop its entire spectrum of aroma. On account of the long roasting time, the coffee is very agreeable because the unwanted chlorogenic acids are “roasted away” mostly.
