More than 1,200 people are expected to show. 40 wineries from Naches Heights to Benton City are formally participating. Wine glasses will be given to guests who visit six participating wineries. Although some visitors from the west side are worried about weather, wineries are optimistic.
"If anything, from what I've heard, there may be some rain on the pass, but it looks like for us it's going to be a sunny weekend," said Kana Winery General Manager Katherine Goodson.
You can buy a premier pass for $35 at select locations over the weekend.
