Best Winery/Vineyard

Over the 3 months that I lived in central California, I visited 16 vineyards in wine country, which included the regions of Napa Valley, Sonoma Valley, Healdsburg, Paso Robles, and Santa Cruz County. The amount of vineyards in central California is absurd… How did I get down to 16? My research started by looking at blogs and well-known magazines which showcased “top vineyards in the nation,” and by asking patients and friends who have visited the area.
