Top Source was established in 2020 by a native Washingtonian, Meredith Hyslop. Meredith started in the wine business in Walla Walla Valley when there were only 25 existing wineries in the region. After studying Enology and Viticulture at the Walla Walla Institute she moved to France to study in Dijon. Her studies brought her to the Languedoc-Roussillon region of France where she worked for 12 years. Upon her return to her home state, she decided to start her own winery to showcase the premium quality of her home state at a competitive price point.
