I have a bunch of old grains I have left over from an all grain I did last year. They weren't moldy, but they definitely smelled old.
So I brewed em up.
6 cups of Rahr 2 row, a cup of English crystal and a cup of Tom Fawcett chocolate into about 1.5 gallons of water. I usually use LME but lacking that, I threw a tablespoon of table sugar in it.
Boiled for 60 minutes. No hops. Why? Didn't have any.
Made a yeast starter...ok not really. I used the yeast from the brew I just racked into the secondary, and threw a pack of bread yeast in for good measure. Yes. Bread yeast. I should mention I'm doing this in a one gallon carboy too.
Cooled it in a sink full of ice water. Poured the half gallon worth of wort into the carboy at about 90* or so and managed to get a bit of sink water into the bottle in the process (fuck!)
Tossed in more sugar and gave that sumbitch a good shake.
The carboy I'm using has a bung somewhere, but I have no idea where it is. So instead I grabbed a piece of plastic wrap, folded it over a bunch and rubber banded that thing tight, poked a small hole in the top and popped in an airlock.
This was about 3 hours ago, and the yeast seem to be pretty happy about life right now.
Not gonna lie. I have no illusions this is going to turn out badly. But I had old shit laying around and I was bored waiting for my cat to take a piss so I could collect it and get it to the vets. Poor critter may have diabetes .
Edit: Oh yea, nothing was sterilized either
