Trisaetum Winery is a family-owned estate located in the Ribbon Ridge AVA of the Willamette Valley, Oregon, near the town of Newberg. Founded by James Frey, the winery takes its name from a blend of his children’s names — Tristan, Shea, and Tatum — reflecting its deeply personal, family-driven roots. Ribbon Ridge is one of the Willamette Valley’s smallest and most distinctive AVAs, known for producing highly focused, terroir-driven wines, particularly Pinot Noir and Riesling.

The estate farms vineyards within Ribbon Ridge as well as nearby sites across the Willamette Valley, where marine sedimentary soils (Willakenzie soils) dominate. These well-drained soils, combined with the region’s cool climate, long growing season, and gentle slopes, create ideal conditions for slow ripening and the development of complex aromatics. Trisaetum focuses primarily on Pinot Noir and Riesling, with vineyards planted at varying elevations to capture different expressions of fruit, acidity, and structure. The combination of site diversity and careful vineyard management allows for layered, site-specific wines.
