Wines I'm making: Grapes Coming Along Nicely (September 23, 2012)
The Cabernet grapes tested at 22.0 degrees Brix. PH was 3.04. PH squared times degrees Brix yields 203 (coincidentally, the same as the Sangiovese). Too early to pick. With the Cabernet, I like to pick at about 24 degrees Brix with the pH at about 3.5. That gives a number of 294 using the rule of thumb, which is nominally on the high side, but most of the books I use for reference in winemaking were written for an East Coast audience and a colder climate--a climate where pH rarely gets as high as it routinely does here, so the number doesn't concern me much. Again, it's just a rule of thumb. This year will be our ninth harvest. I've made the wine enough times by now that I have a feel for what's right. The Cabernet seeds, like the Sangiovese seeds, were brown and moderately crunchy, but, again, not entirely mature. I'm guessing we'll be harvesting in the second week of October, which has been fairly typical. So far, zero losses to raccoons or other critters. The fruit looks great.
