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 23% 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 43% so one thin signal cannot carry the score on its own.

The math on file: renormalized base 92.0 shrunk to 74.2 + bonuses = 75.

    I love Perc! I haven't tried that specific coffee, but I've tried four others and they are consistently excellent

  • r/pourover · 45↑ · Shoutout to PERC

    Big big fan of perc for my daily drivers. I must have bought 5 bags of the benti nenka in the past. I’ll order that papua new guinea and the colombia one this week. Their notes are always sooo salient and spot on. Maybe a bit unidimensional, but I love it for milk based drinks.

  • r/pourover · 15↑ · PERC Benti Nanka is outstanding!

    Perc is outstanding in general. Benti Nenka was awesome. The Colombia Young Producers was unlike any cup I’ve had before. The China was excellent. I’m working my way through the Colombia Los Nogales and then I’m on to the El Salvador Gesha. They recently dropped a few more beans as well. If I didn’t have 5 bags of coff
