I went down an internet rathole on coffee grinders. (I realize you were probably referring to health benefits.)

After many hours of this over many months, I finally looked for a comparison of the actual taste of coffee from cheap grinders versus 10-20x more expensive burr grinders. (As opposed to comparisons of grinder technologies, which are everywhere.)

There are almost no published side-by-side taste comparisons; when I did find one, the cheap grinders had won!

Yes, I was referring to heatlh benefits. Where I live, it's a saying that coffee gives you this and that, but you'll live longer if whatever.

I can imagine, because why would taste matter for a coffee /s ?
