Have 5 gal. of cider in a carboy. Started in Jan with frozen concentrate, 5 pounds of sugar and WLP 775. Didn't get a starting gravity. It was going good god a while, racked and added 48 ounces of craisins. It sat like that till the basement hit 60 degrees then started bubbling again. A couple months later and you can still see the bubbles rising. SG now 1.015. I was gonna let it go until dry but it doesn't seem to be slowing down. Do I need to wait for 1.000? Tastes pretty good now but I need fizz.
