Let me ask a dumb question, why would you want your cider with such a high ABV%?
In my experience 12% is apple wine, not apple cider, but I digress...
The most important ingredient in making any kind of cider, or wine, or beer, is patience.
I normally use ale yeast to make my hard cider, but this batch I put together today is made with wine yeast The yeast is said to tolerate 16% alcohol. I am making apple jack with it, and if the ABV does get that high, I will re sweeten it with fajc, and then freeze it. For me personally, if i am going to stash a bottle of a/j for a special occasion, it will need the "extra" sugar up front, so it will become a nectar of the gods (gods' small g). It makes perfect sense to me now, mead has to condition for years to be amazing, and why couldn't apple jack too? My daughter turns 21 in 4 years, and I need to make a special batch with enough alcohol and residual sugar to stand the test of time.
