I've been trying lots of recommendations in this and similar threads lately. Absolutely loved both Dolce and Vita from Vivace. But the recommendation that has surprisingly disappointed me was Black Cat Intelligensia. I bought a five pound bag of it recently, expecting great things. But no matter how I dosed and ground it, I could never get a satisfying espresso. It was tangy, but it was one-dimensional and lacked any depth or richness. No chocalate or nuttiness. And it was absolutely boring in a cappuccino. I don't know how the O.P. of this thread can put it in the same league as those two from Vivace. I honestly went through a pound of this stuff trying to figure out what the fuss was, or what I was doing wrong, and couldn't figure out a way to make it really enjoyable. Until today.
I was just about to give up on it, when I realized I had a pound of Redbird Brazil Sweet Blue that I needed to hurry up and use. I hadn't tried this coffee yet, but it seems to have a reputation of having a nice chocolate and nutty flavor, but being somewhat one-dimensional for espresso. So I thought: "what the heck, why not try a blend between these two?" I mixed equal amounts of the beans together and started pulling shots. Oh my God! I found the most wonderful espresso blend I have tried yet. The chocolate and nutty Brazilian mated perfectly with the tangy Intelligensia, producing a complex, rich, and delicious espresso and cappuccino.
So if you have some Black Cat Intelligensia and it doesn't measure up to your expectations, I highly recommend blending it with some Redbird Brazil Sweet Blue. Makes for an amazing espresso. Now I just have to order three more pounds of Sweet Blue to blend with the remaining Intelligensia in my freezer.
