I have 2 gallons of welch's I started on the 1st of the month. I used lalvin V1116. I initially had them under the napkin and rubber band for 4 days then put an airlock on. They have been under airlock for around 10 days now and SG is about 0.993. The wine has cleared and there is about 1/8 to 1.4" sediment on the bottom. Should I rack, and should I top up with some grape juice? I have some clover valley grape juice. The ingredients list filtered water, gjc, gj, citric acid, ascorbic acid, and potassium metabisulfite. Thanks in advance, David.
