Sparse signal
Confidence1 of 7 signals on file
Score is heavily shrunk toward 50; treat as a placeholder until more sources arrive.
How confidence affects the score
Coverage measures signal availability, not cup quality. This coffee has 5% of the signal universe on file. Missing sources are dropped, remaining weights are renormalized, and the result is shrunk toward a neutral 50 baseline by 88% so one thin signal cannot carry the score on its own.
The math on file: renormalized base 80.0 shrunk to 53.8 = 54.

…ro honey processed Bourbon Aji with passion fruit, blood orange, and rhubarb liqueur notes. Back in the States I picked up a Wilton Benitez Pink Bourbon from Black & White Coffee Roasters which had a similar intensity, but they’re currently out of stock.

I am trying to dial in this new coffee from Black & White and typically, I’m able to find a good balance of sweetness with acidity in their coffee in a couple cups but this new one is tricky! It was so sour at first that I started at a 56 on my DF64 Gen 2 and ended all the way into the middle of the Moka pot settings t

I cracked open a bag of The Future - Mai Tai from Black & White, and even just off the roast date, it's so good. I've brewed it a few times now and it seems to favor a longer brew period than a shorter one. Grinding the coffee at 14 on my Baratza Encore yields a drain time of 3:00-3:30. It starts off with a slight bitt
