It’s infuriating when you change brands. Built up a feel for how much a bean weighs and how many are needed to go from 17.9 to 18.0g? Yeah, that other bean requires five beans, and not just one.
there are even more niche products, literally called bean counters which dose whole beans to a certain weight. believe it or not they are well over $100. the deep end of coffee is both insane and expensive
Or at least I thought it did until I considered bean-weight variability...
