Winemaker Notes
With hundreds of white grape varieties to choose from, winemakers have the freedom to create a virtually endless assortment of blended white wines. In many European regions, strict laws are in place determining the set of varieties that may be used in white wine blends, but in the New World, experimentation is permitted and encouraged. Blending can be utilized to enhance balance or create complexity, lending different layers of flavors and aromas. For example, a variety that creates a soft and full-bodied white wine blend, like Chardonnay, would do well combined with one that is more fragrant and naturally high in acidity. Sometimes small amounts of a particular variety are added to boost color or aromatics. Blending can take place before or after fermentation, with the latter, more popular option giving more control to the winemaker over the final qualities of the wine.
Three substantial mountain ranges intersect to create a region of great diversity, not only in soil and topography but also climate and as a result, grape varieties.
Where the Klamath Mountains, Coast Range and Cascades converge, is the rather small AVA, the Umpqua Valley, which boasts over 150 soils in a total growing area of merely 1,500 acres. The soils range from sedimentary, metamorphic or volcanic where valley floors are deep alluvium and heavy clay and hillsides are typically silt or clay.
In the Umpqua Valley AVA, vineyards in the north are cooler and wetter; cool climate grapes such as Pinot noir, Pinot gris and Riesling do well. In the warmer and dryer south mainly Syrah and Tempranillo thrive. But growers here are not afraid to investigate new grape varieties; the region is home to over forty types.
There are two sub-AVAs within the boundaries of the Umpqua Valley: Red Hill-Douglas Country, established in 2004 and Elkton, established in 2013.
