I noticed a few people mentioning the Luz Helena Salazar flowing fast in percolation, I also noticed my Switch draw down times were faster than the Foundry expectation, for a similar extraction.
Maybe something that contributes to this is the hardness/density of the bean. I recently purchased a Shore D type durometer, as this was a) cheap and b) a tool already used by a couple of amateur coffee bods in the cyber-coffee-sphere. I was hoping to use this to learn something about roasted coffee, beyond just how hard it is, but nothing is clear yet.
However, bearing in mind any bag of coffee I have measured so far has a wide spread of readings across a selection of beans, the Luz Helena Salazar has by far the hardest average reading of 61.1 vs 57.7 for the next hardest bean and 51.5 for the least hard bean I have measured.
The extraction yields and subjective taste preference scores for the Luz Helena Salazar were all on point, so I am in no way suggesting that this points towards an issue. Nor that a durometer appears to be particularly useful for establishing anything beyond hard, harder, hardest (there may well be a more suitable tool for measuring coffee beans).
I didn’t make any specific grind adjustments for this bean, for filter with regard to my day-to-day brew methods (just an observation & not suggesting that people shouldn’t do so).
Hmmm, maybe I have ‘not said’, more than I ‘have said’ in this post? :-) Anyhow, it piqued my interest.
