This is soon to be the newest sub-AVA within the Willamette. For decades, winemakers and winegrowers have extolled the virtues associated with the influence of the afternoon winds coming inland from the Pacific Ocean, and being funneled through a gap in the Coast Range mountains. This “Van Duzer effect” has a significant impact of style for the wines of this, and some neighboring, regions.
Temperatures are dramatically affected with 20-30 degree drops in the late afternoons. Longer hangtimes throughout the season are a necessity, to incorporate these swings in temperatures; and, more often than not, flavor development is ahead of sugar development. This offers lower potential alcohols. Grape skins tend to become thicker from the winds, resulting in less juice to skin ratio, and often provide wines which have a savoriness and display tightly wound energy at their cores.
