A year ago September, I put up two bottles of applejack from the same batch. A couple of months ago, I found them and my wife and sampled from one of the bottles, wow, I never thought something that amazing was possible from apple juice. No, I didn't O.G. that batch, but after freezing out most of the water, I would just be guessing anyway. I have since put away various flavored versions made at different times this past year. If gallon sized apple juice goes on sale, I buy 2 or 3 along with 5 or 6 cans of frozen concentrate. I add Pasteur Red Yeast and the concentrate in stages along with nutrient, and in less than two weeks fermentation is done, and the apple flavor is great. I always leave the applejack a little sweet at bottling time, as I believe the aged flavor and mouth feel really benefit from it.
The batch I just bottled was made with peaches and apple juice. The peach flavor was very noticeable at bottling.
