I also have the problem of not having much apple taste, I am making my first 1 gal batch (home pressed) I added 1 lb. of table sugar. It has fermented about 10 days and seems to have stopped, tasted it and it seemed bland. I read that you can add concentrate to increase flavor, but I am wondering if I add a concentrate, will it raise the ABV to a level that will kill the yeast? If that happens, will I be able to carbonate when I bottle? I like a high ABV but I also want a good flavor.
