Pre-pruning grapevines

Last year I pre-pruned my vineyard to 6-8 inches once all the leaves fell off. It just makes it easier to do the final pruning end of winter. This year I would like to pre-prune as soon as possible because we need to do some landscape work in the vineyard. Will it hurt anything to pre-prune now (September), we just harvested yesterday?

Cane side shoots

I have been growing Tempranillo wine grapes from cuttings since 2017. I am a novice and learn from reading and the internet. Except for this year, I have let the canes grow from the cordones to the highest wires and almost to the ground before topping the ends to keep them from touching the ground. Once topped I would get side shoots from each leaf and kept the side shoots to a minimum by pinching them off. This year I tried another method, I have seen, and trimmed each cane at the 14th or 15th leaf and for the first time I am getting (almost) no side shoots. Would this be normal for the difference in cane lengths or something else I do not understand. Any response will be helpful. Thanks, Bret Ward @ 909-573-6084 (cell) or

Hello: I'm attempting to track down a non-patent non-gmo non-cloned cutting/stock/bare root/potted Ribier Grape. Seems this varietal is disappearing. I seek it for juice, but also want to try my hand at improve- ment*. Any idea where these may still be hanging on in a home vinyard? I don't need 1,000 (that quantity I could get) just a few to see if they take to this climate. Thanks in advance!


* As I plan to cross pollinate, etc, to develop an improved type, I don't want to step on anyones' patent

re: variety of grapes

hi, I planted my grape vine about 20 years ago. I was busy, and had small children, so i didnt pay attention to the attached tag which said the name of the variety. They are sweet with a slight tartness, small, light green grapes. Is there any way to find out what variety it is, so I can read up more about it? Also, what can I do with the grape leaves? I have heard that tea can be made from just putting the new leaves into hot water, is that true? thanks in advance for your help.

Wine smells like raisins

I am taking a wine class and I need to answer the following question; my red wine smells like raisins and prunes. What can I do in the vineyard next year to prevent this? I cannot find an answer but I suspect it might have to do with sunburned grapes. If anyone can help, that would be great.

What insect/disease leaves peelable, brownish gray, irregular shaped, angular edged, patches on grapevine leafs? I have seen this on the top and underside of the leafs on both my vinifera and frontenac grapevines. In peeling back the patches, I do not see any insect eggs and the patch seems to peel off fairly cleanly.
