Sure. Go ahead.

Coffee grounds are a great food for soil microbes. You can fertilize your soil directly at a rate of 10-20 pounds per 1,000 square feet. Or scatter a handful under the drip line of small plants. Or (waste it) in your compost pile.

Can I use the "never been brewed" coffee grounds?? I have about 20 pounds of mail order coffee that was never used (got it from an estate sale).

Sure. Seems like a waste, though. I love coffee, can't imagine not using it.

Why not try running some through your coffee maker before running to the compost pile? If it's really stale and really bad, compost it. Properly sealed and kept away from moisture, coffee should have a decent shelf life.

Coffee beans, roasted, in a well sealed container can have a very long shelf life, but once ground they go stale quickly. However, even those old, stale, coffee grounds would make a good addition to any compost pile.

Stale Coffee Grounds? Whassat? Never happens around here`!!

:)

Honestly, isnt it one of the seven deadly sins to waste coffee?

Lucky microbes!

Is there any reason why the coffee cant be tried to satisfy a morning hunger.
Seems to me, coffee being as priced as it is....that's an awful expensive addition to a compost pile.

How old is your wine by the way?

Do spread it out though if it does go to the compost or garden. 20lb all in one spot could be overly powerful.

Just as an aside. I know that used coffee grounds are close enough to neutral to be quite safe for most gardening purposes. However, unused coffee grounds may be rather stronger on the acid side as well as the caffeine (which might be a help against snails and slugs?) Anyway, there was a guy who posts on the Vermicomposting forum that ran into an issue with a cold brewed coffee (apparently a process that makes less acidic coffee) where he put the coffee grounds into his worm bin and caused his worms much distress. Apparently those cold brewed coffee grounds were a bit acidic and not very good for the worms.
This probably isn't nearly such an issue for a full sized regular compost pile though.

Got the huge supply from an estate sale for $2 and do not know how old they are but the one bag I opened smells rank. All are ground already. I will boil them and then put them out to get rid of some of the acid. I'm new to compost all I have right now are leaves and these coffee grounds.

I would not concern myself about the amount of "acid" that might potentially be in those coffee grounds. Just like any other source of organic matter it would take tons of that material to even begin to change your soils pH. It is highly unlikely that they would have enough free hydrogen ions to make any change in your soils pH.

While coffee grounds are good material for soil enrichment, perhaps we have been throwing away the best part of the coffee fruit....the berry. This berry is the outer pulp around the coffee bean. It looks like a red cherry and is perhaps the very best anti-oxidant known...by far.
