An interesting argument I hadn't considered. I wonder, though, how genuinely impactful bean quality is for the end product. It's well understood that it's impactful to some degree, but do premium roasters need the top 10%, or is, say, the better half of arabica produced sufficient to yield effectively the same brewed product?

Said another way, is the slope of quality distribution that severe?

Good question, I'd also be interested in the answer.

I'd guess its a long-tailed distribution something like this (https://qph.ec.quoracdn.net/main-qimg-3b21f991d3f0446ce30b9b...) (quality on x axis, volume on y-axis) However, I know little about the complexities of coffee agricultural and manufacturing process, mostly just speaking in abstract armchair economics terms.
