I am purchasing some Marquette grapes from a local grower this year. The numbers over the last month have been very consistently rising:
Date pH Brix
29-Aug 2.6 20.8
5-Sep 2.71 23
12-Sep 2.81 23.6
19-Sep 2.92 25
Of course they are anxious to pick as soon as possible. I'm telling them to give it at a minimum another week - even better two weeks. I'd like to have the pH closer to 3.2. So far it has been a consistent drop in acid of ~0.1 pH every week. At this rate it will take 3 more weeks.
Those more knowledgable - would you think the acid will drop faster as it gets closer? Any insight on how much more time these need?
Thanks.
