Cherrybook Index (CBI)

Evidence-of-quality score, not a cup score. Methodology

78

Strong

Preliminary

Confidence3 of 7 signals on file

Score is partially shrunk toward a neutral 50; read directionally until more source families land.

How confidence affects the score

Coverage measures signal availability, not cup quality. This coffee has 33% 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 18% so one thin signal cannot carry the score on its own.

The math on file: renormalized base 84.1 shrunk to 78.2 = 78.

  • r/Coffee · 25↑ · Why is the V60 so good (vs Chemex)?

    ...ntly been having issues with getting a Chemex brew to extract evenly, no matter what I did it just wouldn't extract properly. I was at a brew class on Saturday past at 3FE (www.3fe.com - a wonderful cafe/roastery in Dublin, Ireland), and one of the brew methods we learnt was the V60. I've had a V60 for a year since

Reviewers and interviewers consistently highlight 3fe as a pioneer in Dublin specialty coffee, led by founder Colin Harmon. Outside coverage emphasizes the brand's evolution from a spare-room and apartment setup into an eight-location empire with a global footprint. Reviewers frequently note the vibrant, community-focused atmosphere of their cafes, which attract a diverse local clientele rather than just a niche hipster demographic. Furthermore, observers acknowledge Harmon's influential role in industry education, notably through his book on running coffee shops and discussions on business sustainability.
