Oh, and I’m not entirely convinced by that vid’s testing methodology. Someone (Stevebee I think) pointed out that the settings seemed to be aimed at a theoretical 20g / 2:1 / 27-30 sec target, which i fine for a starting point but surely, best tasting cup would be better, especially if you then proceed to judge which grinder performed in what way by the taste.
If grinder X is, for instance, overly bright, what hapens if you change your criteria for time, ratio etc? And, of course, it all changes ith a different coffee. And, the whole thing rests one one person’s tasting of a very particular configuration whereas we all both taste differently, and prefer different tastes.
His question was, can hand grinders produce good espresso? Self-evidently, from just seeing comments here, yes. But which is best, or best at a given price point, or vest given that the buyer likes this type of taste, or that? Not so much.
The video seemed to spend about 2/3rds of the time demonstrating dialing in, which is fine if it’s a dialing in test, but a bit beside the point for the question he was trying to answer.
