The small green bottle. When I made that, I just filled the carboy with cider and let it do it's thing. Bottled it, stuck in on the shelf. It's been setting there about 1.5 years now. I think it's about 8% by volume. A little carbonated, real good. The bottle on the left. I added one pound of sugar per gallon of cider + one packet of bread yeast. It came out at about 15% by volume. Most liked it, a couple said they could tast the yeast. Watch it, it sneaks up on ya. The bottle on the right. I used apple concentrate, one pound of sugar per gallon, and wine yeast. Just had a small tast of fresh, just before bottling, tast's good. About 17% by volume. The one in the carboy is the same, only with champagne yeast.
