I make cider using wild yeast. It's always worked fine so far. I think this is fairly common with small-scale cider making in the UK. I do add some sulphite to the juice (amount depends on pH) to discourage the undesirable micro-organisms. If you want consistency then it's probably not a good technique, but that's not what I am after.
