Trinity Valley Winery
Many of the wine sites in California have a microclimate that distinguish them and favor specific wine grape varietals. For example, some of the best vineyard sites sit in valleys that provide cool, foggy ocean air or moderate temperatures. By and large the North and Central Coastal areas are where the vast majority of quality wine production is to be found. The Sierra foothills enjoy a cooler climate than much of the hot Central Valley, and is another area for premium quality wines.
