I was given a Mr Beer that had been sitting around for quite some time. Aside from the keg itself there were some leftover indredients. I know the yeast will be no good and the bags of booster are hard as a rock, so they will need to be thrown out. But I was wondering about the cans. Now they are real old, the date on the bottom is 2006. Do they go bad, or are they like food in cans and last for years. Right now I'm thinking I got the keg, 4 packets of one step, and some reading material. But before I throw away the cans, I thought I'd ask what others think.
