Between permaculture and aquaponics I don't have any time to learn anything else new. And i'm scared to learn how to make whiskey!

I don't have that many friends! Besides this isn't a one time thing. He said he constantly has kegs that go stale and cases that get old. Think there would be any benefit/downfall just pouring it on top of compost piles or even just the soil?
Most beer is around 5% alcohol, so it shouldn't be concentrated enough to sterilize your compost pile. As it is digested by bacteria in the presence of oxygen, the ethanol will turn into acetic acid, so be aware of your soil/compost pH and adjust accordingly. The biggest problem I see is that if you dump a whole keg of beer on your pile it will make it too wet.
The beasties will love the sugar/alcohol.
According to this study ethanol levels from 0.4% to 3% helps and anything over 5% seems to harm soil microbes.
If we had worms or some other critter to close the loop faster rather than slower it would be a big help.
While the beer has a low ph I am pretty sure, the microbe will eat it, the sun will evaporate it and the rain will leach it way.
Also you need to figure out why this person is making so much bad beer. Is he actually making terrible tasting beer, or is it going stale/sour before he can drink it all?
