Wines I'm Making: 2012 Cabernet Harvest
The crushed, de-stemmed grapes yielded 11 gallons of must. I lightly sulfited the must to 53ppm (nine Campden tablets in the 11 gallons of must) and will let it sit for a few days before inoculating with yeast to start fermentation. The must tested at 25.0 Brix and a pH of 3.54. pH squared times Brix was 313. The specific gravity measured 1.108 by hydrometer at about 70 degrees F.
Meanwhile, the rosé from our Sangiovese grapes is ready to be racked off the gross lees. Today is the 15th day of fermentation, and the activity has slowed greatly. I will test with the hydrometer. If it looks completely dry, I will very lightly sulfite the new wine. In about two or three weeks it will be ready for another racking and should by then be mostly clear. Usually the rosé is ready by Thanksgiving.
