Merryvale produces wines in St. Helena, the heart of Napa Valley's most prestigious growing region. The winery's portfolio centers on two distinct expressions: a Stanly Ranch Arvine, a rare varietal that brings mineral precision and structure to the cellar, and a Pinot Noir that captures the elegance characteristic of cooler-climate Californian fruit. Profile, a Bordeaux-style blend of Cabernet Franc, Petit Verdot, and Cabernet Sauvignon, rounds out the core range. These wines have been assessed by Decanter, Wine Enthusiast, Wine Advocate, and Wine Spectator, reflecting the winery's commitment to quality across its lineup. St. Helena's volcanic soils and diurnal temperature swings create ideal conditions for both structured reds and aromatic whites—conditions that shape Merryvale's approach to winemaking in one of California's most storied appellations.
