The Willamette Valley
The core tenet of Trisaetum’s winemaking, owing to the expressive painting philosophy of artist winemaker James Frey, is to let site drive the energy and complexity in each and every bottle. As such, our estate vineyards and the ecosystems they thrive in are the essence of Trisaetum.
Each of our estate vineyards are situated in the storied Willamette Valley of Oregon, one of the few places where climate, soil, and entrepreneurial spirit combine to produce some very special wines.
