Question 22

What is the Van Duzer Corridor and what AVAs does it affect the most?

Answer 22

• McMinnville sits squarely in the mouth of the Van Duzer Corridor, a gap in the Coastal Mountains through which cool, constant Pacific winds blow.
• Eola-Amity Hills is also affected, sitting directly east. Wines exhibit a more rugged tannic structure, deeper color, and more pronounced acidity than in areas further north

Question 23

What affect does the Van Duzer Corridor on grapes in the McMinnville AVA? On Disease? On final flavor of wine?

Answer 23

cold winds strip vines, reduce berry size and crop load, produces thicker skins, and creates general stress for the vine and grower.

Vineyard sites often occupy east-facing slopes in shelter from the west winds. Creates huge diurnal shift (40-50°) and drier microclimate.

The constant gusts fungal issues and create denser, more tannic Pinot Noir wines, loaded with darker fruit flavors and pigment.

A type of Loess soil, windblown and found on mountainsides. These reddish silt soils predate the last ice age and are often intermixed with basalt-derived soils and marine sediments.

Question 33

What are ‘Woodburn’ soil series?

Answer 33

a type of Missoula Flood Deposit, very fertile and on valley floor.
These flood-borne sediments arrived as recently as 12,000 years ago, as the cyclical Missoula Floods roared through the Wallula Gap and the Columbia Gorge, spilling out into the valley. Today about 10% of the Willamette Valley’s vineyards are on these low-lying, deep, fertile soils; they compose the valley floor and are best purposed for other forms of agriculture.
