| Columbia Valley vineyards are seated east of the Cascade
Mountain range. Up to 14,000 feet high, the mountains
effectively block eastward-moving wet weather systems
from the Pacific Ocean.
Just 6 to 8 inches of rainfall reach the growing region annually.
Vineyards are 100% drip irrigation.
The soils have low fertility and low water-holding capacity,
allowing precise control of vine growth patterns.
Vines are planted north to south on south and southeast
facing slopes.
