Penner-Ash produces Pinot Noir in Oregon's Willamette Valley, a region defined by cool-climate precision and the grape's silky complexity. The winery's portfolio centers on single-vineyard expressions that capture the nuance of distinct terroirs. Pas de Nom, the flagship, demonstrates the depth achievable in the region's finest sites, while Maresh Vineyard and Hyland Vineyard Pinot Noirs offer complementary perspectives on Willamette Valley's potential. These wines have drawn assessment from major critics including Wine Advocate, Decanter, Wine Enthusiast, Wine Spectator, and Falstaff, reflecting their standing among serious Pinot Noir producers. The winery's focus remains on the varietal that defines Oregon's reputation—elegant, structured, and reflective of place.
