Warm Weather Indicates an Early 2013 Harvest

If there is one word to describe the summer of 2013 in Walla Walla, it is hot. It’s been the second warmest summer on record. The blazingly sunny days have only been outmatched by the incredibly warm nights. As the Washington State University Agricultural Weather Network noted, “Warm, warmest, and warmer is the best way to characterize the 2013 summer season.” This weather pattern suggests that we’re likely to see an early 2013 harvest.

Washington state as a whole averaged more than two degrees above standard weather. The heat also started early this year. In Walla Walla, we were hitting high temperatures by the beginning of July. August was equally hot; it was the warmest that it has been since 1991. During this time, Walla Walla stayed characteristically dry, with only 0.15 inches of rainfall in August. This dry weather is ideal for wine growing, since it allows winemakers to completely control the amount of water that grapes are exposed to.

What does the summer heat mean for the Walla Faces 2013 Harvest?

This heat decreases the amount of time that it takes for grapes to ripen. After veraison, the grapes throughout the Walla Walla Valley began to ripen quickly. This quick ripening process means that the berries are smaller than usual, making their flavor more concentrated. This will create an intense, flavorful wine.

The Walla Faces Estate Vineyard is at a higher elevation than the rest of the valley. As a result, we have a more temperate climate. Consequentially, veraison and harvest are usually a little later for us than they are for the rest of the valley. However, the warm weather is definitely bumping up the date of the 2013 harvest.

A few storms and some anticipated cooler temperatures will probably slow down the ripening process in the next few weeks. Still, we expect an early harvest date and some bold, fruit-forward 2013 vintages thanks to the weather!
