Added 450 grams of tartaric acid this morning at around 6:30 while doing a pumpover. Got a bit better at the pumpover process, though we had some trouble because grape skins kept coming out the bottom while we were trying to pump only liquid to the top. Supposedly by tomorrow it will be easier because the skins will have risen completely to the top of the tank.

We'll do pumpovers at around 1:30 this afternoon and 10 this evening. Hopefully we'll get the punchdown contraption, too, and do a couple of those.
