Premature Veraison

Veraison. The time has come. No, no, this is not a subsidiary to the cell phone giant, it's a phase of a grape. Why they just don't call it "the grapes are ripening now" is beyond me. It's all part of the secret club. The secret grape growing club. Shhh.

Veraison is a viticulture term meaning the "onset of ripening". It is originally French but has been adopted into English use. The official definition of veraison is "change of color" of the grape berries. Veraison represents the transition from berry growth to berry ripening, and many changes in berry development occur at veraison.

The berry ripening signals that its sugar concentration is increasing. In addition, malic acid degrades and there is an increase of tartaric acid. This acidity will decrease the pH and help in aiding the degradation of chlorophyll.

That said, the only problem is that our grapes seem to be ahead of the curve. Until a couple of days ago, everyone else's red grape were green.
Being a head of the class is not good in this case. It means our grapes will mature too early, and the tartaric acid will not have enough time to degradate from the vine. Meaning the grapes will be very tart.

Sitting back drinking Malbec from a nice open-mouthed Ridel wine glass staring at the vines, I realize there is absolutely nothing we can do. I think we'll just watch them be over achievers and turn that beautiful dark purple color I love so much.

Remember imbibe and enjoy!
