Beringer Vineyards is a large winery in St. Helena, California. Founded in 1875, Beringer Vineyards is 'the oldest continuously operating winery in the Napa Valley', and is thus registered as a California Historical Landmark. It was the first California winery to offer public tours after Prohibition's repeal. In 1939, Beringer invited attendees of the Golden Gate International Exposition to visit the winery using promotional maps printed with the phrase 'All roads lead to Beringer'. The winery also invited Hollywood stars including Clark Gable, Charles Laughton, and Carole Lombard to visit. These early promotions are considered to be the birth of wine-based tourism that is now a large part of Napa Valley's economy today.
