Wow, that is early. What are your final numbers?
Everything is a week or two early this year. Last year, everything was a week or two late.
Turán has been an incredibly difficult grape for me, and I planted it because it was suppose to be an easy grape to cultivate (the complete opposite of my Pinot Noir which I planted to be a challenge and it grows and ripens without too much trouble at all). That said, my Turán reached about 19 brix two weeks ago and pretty much stayed there, with the pH steady creeping up. Then within two days the pH shot up fast, probably because we had another few days of very hot weather. So fast that I could not call the harvest fast enough. That the final cellar crush numbers were brix 20.0 and the pH 3.6.
Meanwhile, my Welschriesling is the complete opposite, stuck at pH 3.0 for the last week, with a steadily climbing brix from 17.6 a week ago, to 19.8 today. More warm weather coming next week (after tonight's thunder storm -- we have had more than normal number of those as well -- probably also due to the hot weather), so expect that pH to also shoot up fast as well soon.
Has been a great growing season, but the harvest is happening unexpected and too suddenly for many growers here to react. Was talking to another grower yesterday, and he wanted to harvest today, but could not get a crew until next weekend.
