After being underwater for over a month due to excessive spring rainfall, Hwy. 94 through Defiance and Augusta, Mo. has officially re-opened, meaning the Augusta Wine Trail is accessible again. Visitors heading to Augusta from St. Charles and St. Louis County areas can access the trail by taking I-64/US-40 to MO-94 W and following the road straight through to a number of accessible wineries along the corridor.
Augusta became the first federally recognized American Viticultural Area [AVA] in 1980, making it the first area in the United States to receive said recognition. The boundaries of the wine region encompass 15 square miles around Augusta near the intersection of St. Charles County, Franklin County, and Warren County. Many of notable wineries located off Hwy 94.
Augusta Winery, Balducci Vineyards, Montelle Winery and Noboleis Vineyards are the four main locations that make up the Augusta Wine Trail. All four wineries are located and operate in the Augusta AVA and utilize grapes grown in Augustan soils while also crafting and producing wine onsite.
