  • Pinot noir and Chardonnay are two of the major varieties grown in the cool climate region of the Pacific Northwest. In Oregon, Pinot noir comprised approximately 43 percent of the total acreage and approximately 6,800 were harvested in 2000. In previous years, Chardonnay (1,125 acres in 2000) had been the number two producing variety in Oregon, however, this year Pinot gris surpassed Chardonnay in the amount planted. One possible reason for the droping popularity of Chardonnay in Oregon, is the lack of a good clonal fit to our environment. The Chardonnay clones used in the initial plantings in Oregon, often times have not ripened early enough to result in high quality wines. Other factors in selecting the best clones for a site include soil type and fertility, local microclimates, the trellis system that will be used, and type of wine that is going to be made. Consequently, clonal evaluation and finding the best fit for different growing are as is very important to the success of the wine industry. In Oregon alone, there are distinct meso-climates in the popular winegrape growing are as such as the Willamette, Rogue and Umpqua valleys, and also the Columbia basin. Within each of these areas, different varieties and clones will be the most successful.
