We picked about 390 lbs of Marquette grapes yesterday. Came out to 36 gallons of must. Brix was 21, PH 3.1. Had a lot of rot this year, 2 vines were almost totally rotten. I think it was because I only used mancozeb once and then used tebuconazole and myclobutani. Next year it’s back to mancozeb. I would like to have waited to harvest but the bees and wasps were getting too numerou.
