Cucamonga Valley Wine Country

Once the largest wine region in California, the Cucamonga Valley AVA keeps the state's deepest wine history alive: century-old own-rooted vines in the sand, Prohibition-era family houses still pouring, and Route 66 running through the middle of it.

Before Prohibition and postwar development, the Cucamonga Valley was the largest wine-producing region in California, with tens of thousands of vine acres spreading across what is now the Inland Empire.

About Cucamonga Valley Wine Country

Every conversation about California wine history runs through the Cucamonga Valley. A century ago this was the largest wine region in the state, tens of thousands of acres of vines rolling across the Inland Empire's sandy alluvial fans, and though freeways and warehouses claimed most of that ground, the survivors are extraordinary: own-rooted vines over a hundred years old still yielding Zinfandel and Mission fruit from soils so sandy phylloxera never took hold.

The living heritage houses carry the story. Galleano Winery has poured from its Mira Loma ranch since 1927, its property recognized as a historic district; Joseph Filippi continues a family line stretching back generations in the valley; and San Antonio Winery's Ontario outpost extends Los Angeles' oldest winery into the region. Tasting here is equal parts wine and time travel, with Route 66 literally running through the appellation.
