The big selling point is the silver skin removed. DIY roasting, without then vacuum the apartment or blow on the balcony and in the garden the film to have, is already a relief. Unfortunately, the "Enthäutungsprozess" is (according to the homepage by mechanical abrasion and hot steam) heavily on bean quality: It has many fragments in the package, the natural roast quickly and easily burn. Who roasts in a simple pan, here has problems. An experiment with a (misused) popcorn machine already delivered better results: The roasting was much more evenly, toasting has also lasted a relatively long time (about 20 minutes). Total household good coffee. Another trigger point there for the rather high costs of supply (was more expensive than the coffee) and the giant cardboard for a very small bag. Here you could certainly save a total achieve a better price-performance ratio.
