Thanks Scott! I did a bit of reading about it, and it seems like the common answer is to do nothing, though one source mentioned that if you see the galls before fruitset (early in the season), that it could make sense to spray for it (not the case here).
Another thing of note is that the main defense is a resistant rootstock. In this case, the birds planted the vine, so it is very possible that it is NOT a resistant rootstock. This could explain why I'm not seeing the issue on my other vines. I'll keep an eye on it next year to see if it is an annual issue on this single vine.
I'm starting to get some UoA grapes as well.
Hope- nice, though small green grape with a decent crispness. 13-14 brix and I'm not sure that they are all the way ripe (a few sour ones).
Faith- I'm having trouble with un-even ripening and YJ/Wasps. Nice flavor on the few which I get and similar brix to Hope (~13)
