I will start a 5 gallon batch of apple wine. I already sliced apples in small pieces and about 50% is frozen, 50% is in fridge. Should I defrost it before putting to fermentation bucket, or just add hot water? Next question - what SG should I start with? Another question - How long the primary fermentation should last? For a fruit wine I do not leave it longer than 4 day usually but I read that apple wine should be left for a week.
