Sonoma County with Napa make up the two most important wine regions. Sonoma has its own feeling and energy, has a more laid back approach and makes definitely the finest Pinot Noir and Chardonnay in California. The best can rival the great Burgundy Chardonnays and Pinot Noir with their own personality. They tend to be richer and more fruit driven with tremendous complexity and length. Sonoma also makes tremendous Zinfandel and Zinfandel based blends. It has tremendous old vine vineyards that make these wines with incredible concentration and balance.
