Estate Vineyards

We cultivate more than 650 vineyard acres in Russian River, Alexander Valley and Sonoma Coast — three Sonoma County appellations known for outstanding grapes. Winemaker Scot Covington selects fruit from distinct blocks on each property for Trione Wines. Vineyard Operations Manager Kris Hicks works closely with Scot throughout the growing season, hand harvesting the grapes at peak ripeness.

Russian River Valley

The geological center of the Russian River AVA marks our River Road Ranch, where moderating sea breezes and cool, foggy nights are ideal for growing desirable Pinot Noir, Syrah, Chardonnay and Sauvignon Blanc. River Road Ranch sits on rolling hills overlooking the site where the Russian River turns west, running toward the Pacific Ocean. Three creeks in riparian zones run through the property.

River Road Ranch

  • Acreage: 125.28 planted
  • Site: 60-114 feet elevation, east-west exposure
  • Soils: sandy clay loam over sandy loam subsoil
  • Years planted: 1998-2009
  • Source of Chardonnay, Sauvignon Blanc, Pinot Noir and Syrah
Sonoma Coast

In hilly terrain and only 10 miles from the Pacific Ocean, Flatridge Ranch grows heritage Zinfandel vines at 1,100 feet elevation in the Sonoma Coast AVA. The Pacific Ocean is less than 10 miles to the west, influencing the daytime shifts in temperature. The elevation and coastal weather give rise to a longer growing season, allowing full flavor development.
