Serious question, I tried a coffee rub on ribs and got a weird bitter crust

I mixed fresh ground coffee with brown sugar and my usual spices for a rack of baby backs last weekend. The bark looked amazing after 5 hours on my offset, but the first bite had a harsh, almost burnt taste. I think the coffee grounds got too dark at 275 degrees. Has anyone found a way to use coffee in rubs without that bitter edge?

Yeah, that "harsh, almost burnt taste" is a common trap with coffee rubs. I've had better luck using instant espresso powder instead of grounds.

Try using a much finer grind next time.

Ever think about blooming the coffee in your rub first? Like, mix the grounds with a tiny bit of hot water or oil before adding the sugar and spices... it sort of pre-brews it and can mellow that raw, bitter punch. I messed up a brisket the same way and started doing this... the flavor gets deeper without the burnt edge. It's a little extra step but makes a huge difference.
