The winery is to be on 10.5 acres at 6170 Washington St. south of Yountville, in the heart of the Napa Valley near Hoffman Lane. The commission approved it by a 4-0 vote last week.

Consultant George Monteverdi said his client came to him and they talked about what would be appropriate on the site.

“He didn’t come to me with ideas for a 100,000-gallon production and 250,000 people a year coming through,” Monteverdi said. “We sat down and talked about what fits on this property.”

The result is what amounts to a small family winery, he said.

Yountville Washington Street Winery won permission to produce up to 30,000 gallons of wine annually and have up to 25 tasting room visitors daily. In addition, it can have 10 marketing events annually with up to 30 people and one annual wine auction event with up to 100 people.

The project includes building a 3,460-square-foot winery building and 1,324-square-foot hospitality building.

About 1.9 acres of the site’s 9.3 acres of vineyards will be removed for the new winery, a county report said. But Monteverdi said the applicant’s family also owns 65 acres of vineyards at nearby Darms Lane. Sending these grapes to the new winery will reduce trips shipping them elsewhere.
