Alioto‑Tournahu is a family‑run winery in the St. Helena AVA of Napa Valley, producing small‑production Sauvignon Blanc and Cabernet Sauvignon exclusively from the historic Tournahu Vineyard just north of St. Helena—a storied site whose Cabernet has earned multiple high‑90s critical scores. Our vineyard lies on an alluvial fan of gravel, clay, and river rocks with exceptional drainage, a Perkins terroir that recalls top Bordeaux estates while capturing St. Helena’s warm. Each wine is crafted to express this singular site with clarity, finesse, and graceful restraint, preserving the distinct character of Tournahu Vineyard in every vintage.
The collaboration among our special parcel of land, St. Helena's distinctive climate, winemaker Rich Frederick, and Master Sommelier Nunzio Alioto has brought our dream to fruition. Our wines stand as a heartfelt homage to George and Evelyn Tournahu.

Estate Sauvignon Blanc
2025 | Tournahu Vineyard | Estate Grown
The aromatics are inviting and layered — white jasmine blossoms followed by Meyer lemon zest, brûléed lemon, green apple, and pink grapefruit, with a quiet whisper of wet stone in the background.
On the palate, the wine's bold, clean acidity takes center stage, beautifully tempered by a slightly creamy, textured mid-palate. Flavors of key lime, Meyer lemon, red kiwi, green pear, ruby grapefruit, and gooseberry weave together before a long, pleasant mineral finish evoking limestone.
