Wines I'm Making: 2013 Grape Harvest (October 6, 2013)
It's somewhat early for the Cabernet (October 18 in 2012), but a fair number of clusters were already turning to raisins, probably because I watered less than usual this year (only twice, rather than three of four times in most years) and it seemed best not to wait any longer. We harvested 20.5kg (or 45.1 lbs) of Sangiovese grapes, which became just under eight gallons of must after crushing and de-stemming. The must measured 22 degrees Brix with pH at 3.63, just about right for the light rosé these grapes will become.
[Update: This afternoon (October 9) I dissolved 15g of tartaric acid crystals in 2.5l of distilled water (using a formula provided by the kind people at The Beverage People) and added the mixture to the Cabernet must. It was difficult to mix it all in evenly, so, measuring the Brix after the addition, it comes out a bit low (at 23 degrees Brix), but I suspect that's simply because of an imperfect mixture. The sweetest juice is probably stuck at the bottom of the container. The aim was to reduce the sugar to 25.5 Brix. I'll stir it up again tomorrow and test it once more.]
