This is highly subjective and depends on wine preferences, but regions frequently cited as among the world's best include Bordeaux and Burgundy in France, Tuscany and Piedmont in Italy, Napa Valley and Sonoma in California, Rioja in Spain, and the Douro Valley in Portugal. Bordeaux and Burgundy often top lists for traditional European wines, while Napa Valley leads for New World wines.
Napa Valley has approximately 475-500 wineries, though the exact number fluctuates as new wineries open and others close or consolidate. Despite being a relatively small wine region geographically, it's one of the most concentrated and prestigious wine-producing areas in the world.
Paso Robles in San Luis Obispo County has over 200 wineries and is often cited as having the most wineries of any California town or region. However, if counting by broader wine region rather than individual town, both Napa Valley and Sonoma County collectively have more wineries than any single town.
