My friend and I started off killing off the wild yeast and using english cider yeast for the 1sr 40 gal batch. The next year we decided to ditch the sulfite and use english cider yeast for an 80 gal batch. Tasted a lot better. The fall of 2012 we juiced 180 gallons, with no cider yeast at midwest or northern we said screw it and didn't add any yeast. Fermented in one container. Wild yeast and who knows what kinds of bacteria fermented out to nearly very dry. The wild batch does have a ''smokey'' flavor. We may be doing the same this fall.
