What percentage of Oregon's wineries are located in the Willamette Valley?

• A. 40%
• B. 60%
• C. 70%
• D. 80%

Answer: (C)

The Willamette Valley is where most of Oregon’s wine activity is centered, so it holds the largest share of wineries. Its cool-climate conditions are ideal for Pinot Noir and other varietals common in the state, and the region has long been the hub of Oregon wine production and tourism, with many established vineyards and tasting rooms clustered there. Because of this concentration, about seven-tenths of Oregon’s wineries are in the Willamette Valley, while the rest are spread across other regions such as Southern Oregon, Umpqua, Rogue Valley, and Columbia Gorge. This distribution explains why that percentage best represents the reality: a clear majority in the valley, with a smaller number outside. The other figures would either underestimate the valley’s dominance or overstate how many wineries are elsewhere.
