Discussion of various types and blends of commercially available pre-roasted beans, their best sources, prices, their respective merits, and the Vivaldi settings required to optimism flavor.
From what I recall, I was able to pull Black Pearl between 94-96 degrees with nice flavors in that range.
Your Mazzer Mini Type B should grind that pretty well at about 5 notches finer than the factory setting.
...with a 30lb tamp.
Maybe it's a little strange but as I read your grind setting on your Mazzer, it would be a not-a-single-drip setting on mine and very near to zero point
