|it's not the solidification that's the problem. there's freezer burn, there's the freezing of the coffee oils that turns the coffee more bitter, etc.
but if you already have ground coffee anyway, i don't think it's that big of a deal...coffee should be ground right before brewing.
Oh I see, I didn't even think of freezer burn or frozen coffee oils
I just thought it would keep fresher for longer. Grinding beans is so noisy that I like to make extra so I don't have to listen to the grinder for a while! I don't like the thought of freezing coffee oils though, so I won't be doing it again.
