I am in North Alberta and my two 8yr old Valiant grapes gave me 4gal of secondary wine. I only had 1-14 pH strips that said pH 2 in the fresh crushed/ pressed juice. SG 1.108 after adding 1.5 gal water and 8 lbs sugar. I don't have my brew book with me and just read that I should add nutrient mid way. I am at 1.030 and just pressed again and racked it into a 3gal and a 1gal jugs. Should I rack back into a pail while it is very active, add nutrient and re-airlock? Should I leave it as I'm too far for that now? More details when I have my log.
