This map shows the current AVAs, soils and even the vineyard blocks. We thank the Willamette Valley Wineries Association for allowing us to use it and pass along their acknowledgements “Map data by everyvine.com, design by John Fisher, geologic cross section by Timothy A. Cross, special thanks to Patrick Reuter.”
The Willamette Valley is 60 miles wide at it’s widest (east to west), but is over 100 miles long (north to south), so you will note that the map is flipped so that as you look at it North is to the left, East is up, South is to the right and West (where you will find the Pacific Ocean over the Coast Range) is down.
The overall valley is the Willamette Valley AVA and within it there are currently 6 sub-appellations.
Willamette Valley AVA
The overall AVA spans the area from the Portland in the North to Eugene Oregon in the South and sits between the Coastal and Cascade Ranges. Plantings began in 1966 and the AVA itself was established in 1983. The base of the valley itself is fertile and great for agriculture, except of course for grapes. Grapes need the struggle to be tasty enough to make wine. As a result, most of the vineyards will be between 200 and 1000 feet in elevation.
Within this large AVA you will find the 6 sub-appellations, one of which is nested inside another. We will work our way from North to South (left to right on the map as you look at it)
