In waupaca wi I came yesterday after being on vacation for two weeks. While gone it seems the weather was cool and very wet. When I left my Marquette was at 18 brix, when I got back it was only at 20 brix. I harvested anyway as the pressure from wasps, ants and fungus was scaring me. Due to the deer eating most of the flowers in spring I only have 8-10 gallons of must right now about. I took my time and destemmed by hand and removed all berries that had been attacked by bugs etc, should be good tasting wine. The berries tasted ripe just low on sugar maybe due to the 10 inches of rain we got over the last two weeks. The PH was 3.2, I like a higher PH for drinkability so I added 20 grams each of calcium carbonate and potassium bicarbonate and got the PH up to 3.6.. even with that much the flavor is unaffected.. can't wait for next year.
