Ditched my electric grinder for a hand crank and wow what a difference

I got tired of my $40 blade grinder making my morning coffee taste like dust (you know, that burnt flavor). So last month I grabbed a cheap hand crank burr grinder off Amazon for like $25. Took me 90 seconds of cranking instead of 10 seconds of buzzing. But the first cup I brewed with it? Night and day. Even with the same beans and same brew method, the flavor was way cleaner. No more bitter notes hiding the actual coffee taste. Has anyone else switched from electric to manual and noticed this big of a jump?

The big thing nobody talks about is how electric grinders heat up the beans from the friction. That heat cooks off the volatile oils before they even hit the water (the stuff that makes coffee smell like blueberries or chocolate). My $25 hand grinder keeps the beans cold, so I actually taste the fruitiness in my Ethiopian beans now instead of just ash. Plus the uniform grind size means less tiny dust particles overextracting.

Is it actually the friction heating up the beans, though? I've seen some testing that shows most electric grinders don't really heat the beans enough to cook off flavors unless you're grinding for like 30 seconds straight. The bigger difference is probably just the way more even grind size from the burrs versus the blades smashing everything unevenly.
