Decaf Sumatra is just the best decaf I've ever found. It has more body and flavor than any other origin. The Swiss Water method removes 99% of the caffeine.
The beans start cracking a little bit sooner than caffeinated Sumatra, but otherwise, treat it about the same. As a general rule, decaf does better in darker roasts, and Sumatra is naturally a good candidate for dark roasts, so that’s what I do with it — about 30 seconds into the second cracks. You will notice that the body and flavor hold up pretty well. There is a slight strawberry sweetness against a dark chocolate note. The aftertaste is clean. It is very smooth coffee.
