Some people can get by without nets for early harvest white grapes. Edelweiss and Brianna are two examples of white grapes that are harvested around 15-18 brix. Some of the vineyards near me don't bother netting them. Red wine grapes and later harvest white grapes need protection. You will probably lose half your crop or more if you don't net. A small vineyard can lose everything.Hi everyone! This is my first year letting my grapes grow (3rd) and they are growing nicely. My question is do you use netting to keep the birds out? I live in the Seattle area.
