Schramsberg

This enchanted winery has survived miraculously intact since 1862, and it's hit a 50-year winning streak producing California’s most distinctive brut sparkling wines. Explore the historic caves to glimpse the traditional riddling and racking process firsthand, then emerge to the Napa Green–certified wine estate to sample the tête de cuvées (best of the vintage). Go with the giddy all-sparkling experience to concentrate on signature blanc de blancs (bottles $29 to $110).
