Noted

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 83.7 shrunk to 69.3 + bonuses = 66.

Cherrybook summary of the video

Marty Lopes of Roseline Coffee in Portland, Oregon gives a tour of his roasting facility, detailing their small batch approach to roasting single-origin coffees and explaining the equipment choices behind their roasting style.

Inside this video

From Online Barista Training:

“We have a focus on single origin coffees that have unique characteristics to them, because we want to highlight what those coffees have to offer in terms of variety and origin characteristics.”
“I think it's really important to understand the different types of roasters out there, because they all have different results and they all have their own quirks.”
