Marquette starting veraison

[wood1954]

From what I’ve read 3.15 is a pretty good pH for Marquette. Hope the harvest goes well. Does it typically drop as the Brix goes up?

The acid should drop as brix goes up I’m hoping for 3.2 which after MLF should be about 3.4

I spent two hours picking any grapes that were starting to rot or shrivel up. By keeping them out that should help keep the wasps away. So far no wasps or birds or stink bugs. I hope to pick in two weeks.

Yes. That’s what I meant. I should have been more specific. Acid drops and pH rises as they ripen.

PH goes up as acid drops. I an shooting for a PH of 3.3
