This coffee is wonderful. At the Vienna roast the is very smooth and full flavored with no bitterness. As a newby to roasting, I found these coffees to be to be far superior to anything available at any store. This Tanzanian Peaberry is very nice and was quick to roast. I still have my training wheels on and have not ruined any of my roasts. I am learning by experience the different flavors and degrees of roast.
