So I've brewed one batch which turned out quite tasty but started looking into making ciders since my girlfriend is partial to them. It looks pretty stupid easy to make a good cider. I was cleaning out the fridge the other day and found about two quarts of apple juice that has been in the fridge like a month. I was getting ready to toss it when I saw a bottle of home brew dregs sitting in a bottle of my home brew that I'd just poured. So it occurred to me to just pour in the year/trub from that bottle into the juice and see what happens. I know I vastly under-pitched the yeast since there was probably only a teaspoon or two in the beer bottle. But I figured I was going to throw this stuff out anyway, why not give it a try? I'm doing zero fermentation temperature control other than the fact that my house is 64ish degrees this time of year. The yeast was US-05. What do you guys think is going to happen? A solid krausen formed about 3 days into the fermentation and it appears to be replicating nicely in there. Have I made garbage, or something drinkable?
