Napa and Sonoma vineyards have been doing it for decades: https://www.sfgate.com/business/article/vintners-rush-to-dry... (dated 1997)

It’s pretty rare though. They usually only do it when it rains heavily right before harvest.

parent comment said “every time it rains”… this article and your comment make it sound “pretty rare”.

I could certainly be wrong about the timing. I’m definitely not a grape growing expert by any means, I mostly know about it from being in the UAV world and having had some discussions about replacing the helicopters with drones for getting the water off.
