I've recently done up a batch of "turbo cider". I did two gallons with a beer yeast that I had lying around, and another 5 gallons with a cider yeast. I did add grated apple for body and tea for tannin, but not sure how necessary those steps were. I bottled the ale yeast batch a couple of weeks ago, and not bad, more like a wine than a cider, very sharp, but probably would have mellowed given the chance, but nearly gone now. I bottled the cider yeast batch yesterday, so will give that a while before tucking in. Chmapagne yeast for next batch.
