Along the modest elevations the climate is generally quite warm, which makes many of its sites well suited to Cabernet Sauvignon and Zinfandel. Vineyard acreage has approached (if not already surpassed) 7,000 acres, with red Paso Robles wine varieties enjoying a slight lead. The primary Paso Robles white wines grown are Sauvignon Blanc, Chardonnay, and Chenin Blanc. Zinfandel and Cabernet lead the reds in both quantity and overall quality.
