OK, so I'm starting a 3 gallon batch of green apple cider in my 6 gallon fermentation bucket. I've cut up about 3 pounds of apples, added my sugar, added my water. But, too late, I realized I'm out of brewing yeast. I could attempt to do it with the natural yeast on the apples (these literally came straight off the tree and got a quick rinse before being cut up), but I don't know if that's going to be enough. Should I just try to find a brick and mortar spot that can sell me yeast so I don't have to wait too long? Can I use baker's instant yeast Do I need to add more water to my bucket to avoid making vinegar? Help!
