Apple Pie is a potent beverage made of apples, cinnamon, and Everclear. Tends to be found at Ren-type events, like what the SCA does. And some Fen type events.
The Everclear is used as the base, because after mixing with the other ingredients, the alchohol content drops from 195 proof to about 80 proof.
Gotta be careful to not go overboard with the cinnamon (you'd be surprised how many do go overboard). And if made just right, you can't hardly (if at all) taste the alcohol.
Within the past few years, I've been making double batches and stowing half to age (something not common with Pie. But trust me, aged is better). Meaning, I currently have 4 and 3 year old bottles of Apple Pie (Gonna save the aged stuff for really special occasions).
This sounds similar to German Afpelkorn (Apple schnapps) to me, but what is the ratio of apple juice to alcohol, to drop it's alcohol level from 97.5% to 40%, Mon Captiene...?
The nearest commercially produced version to your "Apple Pie", as far as I know, would be Berentzen's Winter Apfel, which is made only during winter in Germany, & comes in a Red glass bottle...
However, it's alcohol level is 18% (36 proof), as compared to "Apple Pie's" 40% (80 proof), & they do not produce a aged version...
