I’ve created a summary table that contains information for each of Washington’s 20 appellations plus The Rocks District of Milton-Freewater, a nested appellation of on the Oregon side of Walla Walla Valley. The table contains the following information:

  • Appellation name
  • Year first modern-day grape vines planted and year appellation established
  • Total acreage, total planted acreage, and percent of Washington’s total plantings
  • Minimum and maximum elevation above sea level
  • Growing Degree Days (a measure of heat accumulation) and average annual precipitation in inches
  • Soil information
  • Main varieties and the percentage of red versus white varieties planted
  • Two things to know about the appellation
  • Articles I have written about the appellation

This information was collated from appellation applications, acreage reports, the Washington State Wine Commission, Washington State University, personal interviews, and other sources. I’ve given an example of what this looks like below. The full table of Washington appellation information can be found here. Note that access to this information is restricted to subscribers (click here to subscribe).

It can also be found under the main menu “Resources” -> “WA Appellation Info.”
