Van Duzer Corridor

The Van Duzer Corridor is the newest American Viticultural Area (AVA) in Oregon, legally established in January 2019. It's entirely within the Willamette Valley AVA in Polk County.

From Wikipedia:

Topography is characterized by low elevations and gently rolling hills. The low elevations allow cool breezes to flow relatively unimpeded from the Pacific Ocean, through the Oregon Coast Range, forming a wind corridor gap known as the Van Duzer corridor. The western end of the Van Duzer Corridor wind gap is narrow and squeezed by high elevations to the north and south, leaving little room for viticulture. However, the eastern end of the Van Duzer Corridor wind gap, where the Van Duzer Corridor AVA is located, features the same low elevations and rolling hills as the western portion, with the distinction of having a wider area suitable for vineyards. Within the Van Duzer Corridor AVA, the elevation does not impede the eastward-flowing marine air, allowing higher wind speeds to flow through. In contrast, the surrounding regions all have higher elevations.

The consistently high winds in the AVA contribute to thicker grape skins, and raise the levels of phenolic compounds in the fruit. In contrast, the wind speeds to the north and south southeast of the AVA are slower. ... The cooler temperatures ripen the fruit slowly, creating a longer hang time... [and thus,] a reduced acidity level.
