Previously, Lyon was the winemaker for Sebastiani Vineyards for 37 years. The wine portfolio from the estate vineyards includes a Cabernet Sauvignon, Old Vine Cabernet Sauvignon (40+ year old vines), Three Vine Red, (a blend of Merlot, Cabernet Franc, and Petit Verdot), Barrel Fermented Chardonnay, and “Cuvée Acero” Sauvignon Blanc.
