Vinifera in Wisconsin? Yes We Can! almost .....

Karen and Jack picking the Cabernet Franc.

Saturday October 17 we picked the vinifera grapes in the high tunnel. We picked at sugar levels much lower than ideal. We had a very hard freeze the weekend before (20F,) and the high tunnel got to 29 F, so ripening had pretty much stopped.

The vines were hit pretty hard with powdery mildew this year, due to some poor vineyard management by yours truly. The ripening on the cab sauvignon, cab franc and merlot was just creeping along over the last month and a half. Only the chardonnay escaped the full brunt of the powdery mildew. The Cab franc and Cab Sauv were very under ripe. (not quite 16 brix) Merlot made it too almost 19 brix, and chardonnay did best of all, getting to 21.2 brix before the freeze.

I will definitely have to be more aggressive with my spray program next year. I think that in a normal year, with better viticulture practices, I should be able to reach the low 20's in brix.

I stumbled upon your blog a short time ago and was impressed at your Candor. Having managed a 16 vineyard in Surrey, BC for 10 years I have a good idea what you are going through. Uphill battle is an understatement. I did come up with a lot of tricks that accelerate ripening with varying degrees of success including tenting, girdling, and hormone treatments. The best grapes for that area were whites...Marachael Foch being the exception for reds. If I had only Siegerrebe I could make an excellent Gewurztraminer style wine that would ripen before the summer was over! Enjoying your blog! George bcgrapes@gmail.com
