Mario’s Vineyard, St. Helena Named for our pioneering founder Mario Trinchero, this rare jewel of a site surrounds our winery in St. Helena, along a narrow, 13-acre stretch of the valley floor formed by river erosion. A northwest exposure, coupled with a mix of gravel, loam and alluvial soils, translates to impressive structure and velvety tannins in the glass. Haystack Vineyard, Atlas Peak Haystack Vineyard is nestled high in Atlas Peak, Napa Valley’s most elevated appellation, perched 1,500 feet above sea level in the Vaca Mountains. This craggy, extremely rocky site stresses the vines, resulting in small, intensely concentrated berries. Central Park West Vineyard, St. Helena High above the Napa Valley floor in the Mayacamas Mountains, our Cloud’s Nest Vineyard embodies the greatness of the Mt. Veeder appellation. This highaltitude vineyard is incredibly steep with gravelly soil, and like all of our vineyards, must be patiently farmed by hand. Its cool, eastern exposure allows for extended hang time, which imbues the grapes with greater complexity and character.
