Aye, but my question is really about unused grounds. I've just smashed a load of old/undrinkable beans through the grinder to break the grinder in, but it seems really wasteful to bin them, but I also don't want to shag my plants with a potential contaminant.
I'm probably overthinking it, and will likely just add a load of boiling water to them and pour off the water to be sure.

I’ve been grinding through some shit/random old beans I had in the back of the cupboard to break the new grinder in after my first cup was a bit lack lustre (had a decent layer of sludge on top) and read that it usually takes about a kg of beans to take the really sharp edges off the burrs, and after that the fines should decrease. First cup wasn’t exactly bright.
A slightly related question is, should I rinse the grounds if I want to use them in compost? Caffeine not being great, or am I overthinking it?
