J. Bookwalter produces wines from Columbia Valley, Washington's expansive growing region. The winery's portfolio centers on two flagship blends that have attracted attention from major critics. Chapter combines Merlot, Shiraz, and Cabernet Sauvignon into a red blend; 2nd Edition pairs Sauvignon Blanc with Sémillon and Muscadelle for a white. Both wines have earned ratings of 94 points from prestige critics including Wine Advocate, Wine Enthusiast, Wine Spectator, and Decanter. The Protagonist Dionysus Vineyard Cabernet Sauvignon, a single-varietal expression, has also been rated by these same critics. Columbia Valley's warm days and cool nights suit the ripening of Cabernet Sauvignon and Merlot, while the region's elevation and diurnal temperature swing support aromatic white varieties. J. Bookwalter's focus on structured reds and balanced whites reflects the terroir of this established Washington appellation.
