I have little experience with decaf but the café I used to work at carried a couple of Zab’s decaf roast which were very tasty. On their website it seems like they only have the Colombian decaf in stock, which is definitely their more basic offering (still good!) However they’ve done really funky and cool decaf roasts in the past, so it might be worth checking their website occasionally if you’re into the third wave, fruity notes kind of coffee.
