Although the relatively warm Umpqua Valley south of Portland was the site of the very first winery of the resurgence, early growers concentrated their efforts on the cooler Willamette Valley, to the southwest. The Pinot Noirs of the Willamette Valley have consistently shown well in comparative tastings with the Pinot Noirs of Burgundy; so much so that there is now considerable French investment in the region. Pinot Gris is another successful variety, producing fresh, crisp wines that are excellent with seafood. Chardonnay was disappointing for a time, with climate-related leaness and acidity, but has dramatically improved with the introduction of Dijon clones. Plantings of Gewurztraminer, Riesling and Pinot Blanc produce fine examples of these less commercially popular, but delicious varieties.
