As early as the 1840s, French settlers brought their knowledge of wine to Washington's Walla Walla Valley. The highly fertile soil and abundant water were perfect complements to their Old World winemaking traditions, halted only by Prohibition and the historically unmerciful weather conditions. A century after the first settlers arrived, the area's wine industry reestablished itself when new pioneers like the Italian Pesciallos and Leonettis opened wineries in the early and mid-1900s, a trade that continues to thrive today.
