I am still confused as to when to add the apple juice. As far as flavors/extracts go, a tiny bit of apricot flavor will really bring out the apple flavor. I have added just apple flavor, and the apple presence was minimal until I added the apricot and a little sweetener as well. I am only talking about 1-2 oz of apricot as an adjunct. I always add a little apricot to any of my apple creations, and always at bottling.
