Number of states that a total solar eclipse will cross in 2017. The Willamette Valley in Oregon is the only major U.S. wine region that lies directly in the path of totality on August 21. Already in the planning stages are events on east-facing vineyard blocks with great sky views. Considerable amounts of great pinot noir will undoubtedly be drunk. This will be the first total solar eclipse in the continental U.S. since 1979.
