Sparse signal
Confidence2 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 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 73.6 shrunk to 63.6 + bonuses = 61.

Two independent Reddit threads give Clifton Coffee a favorable but qualified picture. One drinker found its Yunnan coffee complex, subtly sweet, and surprisingly good but said it would not make their top 10 or top 20; a Bristol commenter named Clifton as their local choice.

...China (well, from Britain, but the coffee comes from China). It comes from Yunnan province, specifically, from the Fuyan Coffee Coop, and my brother got it from Clifton Roasters in Bristol. I’ll say this: not bad at all. Complex, subtly sweet, with a citrusy bitterness in the background. Wouldn’t make my top 10 list
- r/espresso · 9↑ · Have I missed any must have UK roasters from my list!
I’m a big fan of local roasters so for me in Bristol I go for Clifton but there are also Extract and Wogan coffee locally (a lot coffee shops in Bristol use Extract or Clifton)
