Here is what I just did: I had a gallon I used to top off another batch, and I didn't really measure it first. I couldn't find the apricots this morning, so I used peaches. I strained out the fruit, mashed it in a sanitized zip top bag, and then added both the fruit and the syrup. I added in total: 2 - 15 oz cans of sliced peaches with the syrup, 2 - 12 oz cans of apple juice concentrate, 1 tsp of Pasteur Red wine yeast, 1/4 tsp of DAP, 1/4 tsp of Fermaid K, 1 tsp of pectic enzyme, and have a total of 10 pints of soon to be cider. Be careful; DAP and Fermaid K ,will cause volcanoes in your fermenters. Trust me. That is why I split this batch in two.
Addendum: Today, after fermenting @71 for four days the alcohol % has got to be really high, as it was very noticeable, and fermentation seemed to have been done. I added a 12oz can of apple juice concentrate and 16oz of water to each jug, and within an hour fermentation was obvious again. Before I added the new juice when I tasted it, not only was there alcohol warmth, but the flavor of the peaches was still there. I will probably puree the must, and add gelatin before cold crashing until clear. At that point, I will put the cider in the freezer and wait impatiently before separating the water from the alcohol.
Addendum II: 9 or 10 hours later, the airlocks are busier than a $20.00 hooker on payday. Not like I would know myself...
