Exploring Our Vineyards: Sonoma County Terroir


At Trione Winery, our passion for winemaking is deeply intertwined with our reverence for the land. For 17 years, we have dedicated ourselves to cultivating exceptional wines that showcase the unique terroir of Sonoma County. Join us on a captivating journey as we delve into the heart of our vineyards, where the art of winemaking begins and where the Trione family grew roots.

A Legacy of Vineyard Excellence: With three generations farming premium wine grapes across five estate vineyard ranches, Trione Winery is rooted in Sonoma County's rich wine heritage. Brothers Mark and Vic Trione, dedicated farmers for over fifty years, have nurtured close to 600 vineyard acres spread across three prestigious appellations: Russian River Valley, Alexander Valley, and Sonoma Coast. This legacy of vineyard excellence is the cornerstone of our winemaking philosophy.

Russian River Valley: Nestled in the cool climate of the Russian River Valley, our vineyards at River Road Ranch benefit from the region's fog-blanketed mornings and warm, breezy afternoons. This unique microclimate allows fruit to ripen slowly to produce wines that capture the vibrant acidity and complex flavors characteristic of this renowned appellation. From Sauvignon Blanc and Chardonnay to Pinot Noir, our River Road Ranch wines embody the essence of elegance and refinement.

Sonoma Coast: Embracing the rugged beauty of the Sonoma Coast at an elevation of 1,200 feet, Flatridge Ranch is part wilderness preserve and part vineyard site. What was once slated for logging, the ranch is now home to endless game trails, creeks, and mountain peaks spanning 11,000 acres. Only nine of these acres are planted to Zinfandel overlooking the Pacific Ocean just nine miles to the west. This fruit is influenced by the maritime climate, but the warming rays of the sun that breaks through the fog at this higher elevation and the region's well-drained soils. yield exceptionally unique wines.

Alexander Valley: Stretching along the eastern foothills of the Mayacama Mountains, the Alexander Valley appellation offers a diverse range of soils and microclimates.  Here, our vineyards thrive in the warm, sunny days and cool nights, resulting in wines with remarkable depth and structure. The Cloverdale Ranch is home to the three acre Block 21 producing a Cabernet Sauvignon that exemplifies the bold and velvety characteristics that have made this appellation famous. The Geyserville Ranch is comprised of the Bordeaux varietals that make up our popular Henry’s Blend. And the 263 acres at Nervo-Home Ranch grow everything from Chardonnay to Primitivo.
