Napa Valley. Family Winery and Vineyards, Since 1978. The Hess Collection was founded in the far reaches of the Napa Valley. Allomi Cabernet Sauvignon is sourced from the low rolling hills of the valley where the warm temperatures create a wine with rich, seamless tannins and concentrated fruit flavors. The Hess Collection's vineyards & winery are certified by the California Sustainable Winegrowing Alliance. - Donald Hess, Founder.
