Tonight marks the end of day 4 of primary fermentation. I added the second half dose of Fermaid K just ahead of the 1/3 sugar break, at the end of day 3. Kit instructions say to allow 6-8 days before proceeding to step 2: secondary fermentation (rack to a carboy with airlock). Step 2 says to rack to carboy when SG reaches 1.020 or lower. The way things are trending, the SG should hit 1.020 by the end of day 5. * the entire timeline on this graph is 7 days I'm thinking the right thing to do is ignore the calendar and listen to the hydrometer. Am I thinking clear thoughts? How low (SG) can I leave it in the primary and not risk oxidizing the wine? Should I leave it in the primary for 6 days, and rack it dry? Or rack it as soon as it hits 1.020 or some other magic number?
