don't you only see these being used when other preferable infrastructure has already failed, and it's like, an emergency or something?

    That’s exactly why this is done. It’s an emergency operation if there is a sudden freeze that would kill the vines.

    A sudden freeze will not kill the vines. Grapes are extremely tough. It can hurt the flower buds though. A severe enough freeze can cut the yield.

    For wine grapes less fruit in the bunches = lower quality wine.
