    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?

    Don't get too hung up on the EXACT time to move to secondary. If you can, a good time is 1.020-1.010, but I have had a couple ferment dry in the bucket (.990), and they turned out fine.

    The question I ask myself is: 'Does the wine have a blanket of CO2 covering it?' If the answer is 'maybe', then I'm worried.

    You’re on track, let the hydrometer / SG be your guide at this stage, not time.

    If you have active fermentation, your wine is fine to stay in it’s primary vessel, as it nears completion, we move it to a vessel where we can control air exposure as well as get rid of some of the heavier lees that have begun to settle out. Exactly when is your call, though the closer to “done” you are, the lower the chances of overflows / airlock foaming / volcanoes is. Some folks completely finish AF in primary, others rack at 1020, 1010, 1000, you get to choose.

    What I normally do is keep the lid loose until it gets to around 1.010 or below. Then I snap the lid and put in the air lock to make sure I have a CO2 blanket. I then let it go to dry or almost dry.

    Fermentation was very tame. It would’ve been fine in a 7 gallon pot.
    The only pucker moment came when I added the Fermaid K.
    That’s a great way to degas!

    On day 6, 1.020, and I racked into a 6 gallon carboy.
    It's now day 9, still at 1.010. If the trend continues, this will probably be dry a week from now.
    There currently sits 3/4" of fine lees on the bottom. Should this concern me at all?

    I've read where it's recommended to rack off of the fine lees once they build up to 1/2".
    Are these lees going to funk my wine in the next week?

    My heart says to just wait until it's dry before racking again.
    But I really don't know.

    Does the height of the lees matter for a week or two?

    You should be fine to let it go, infact you may want to stir it daily to stir up the lees. You probably don't have 3/4" anyway. The lees get attached to the glass and there is probably only the appearance of 3/4" around the base.

    I have not done a thing to the wine, no stirring up the lees, no racking.
    Here we are on day 18 since pitch, SG reads 1.001.
    I can still see a steady stream of tiny bubbles working their way up to the surface. Airlock still gluggs a few time a minute.
    But it is almost 3 weeks into fermentation. That 50% longer than everyone else.
    I'm not worried. Should I be?
    Should I consider stirring up the lees? Or just practice patience?

    I usually stir my fermentations twice a day, but I also usually have a "cap" of skins to deal with. That said, your ferment is working its way down to dry; so I would say not to worry.

    I still have not done a thing to the wine, and it's bubbling away. Bubbling has slowed down a fair amount. SG is down to 0.997.
    Tomorrow marks day 28 since pitched.

    Either RC212 is way slower than EC1118, or I racked into the carboy too early.
    At least there was a happy ending.
