If you’ve stopped by the vineyard in the past few days, you may have noticed a beautiful thing: Veraison has finally come to the Walla Faces Estate Vineyard!
Veraison is the process by which grapes turn from green to red. Before verasion, the grapes are simply getting bigger; cells divide and expand, resulting in larger and larger grapes. After veraison, grapes begin to ripen: the acidity of the grapes decreases, sugars become concentrated, and chemicals that give off herbaceous aromas degrade, leaving you with a beautiful, fruity scent. The berries will also get much softer. Prior to verasion, the grapes are very firm. Afterwards, they become much more supple. This is also the point at which a keen observer may be able to discern the characteristics of different grape varieties.
We’ve seen veraison in other vineyards in the Walla Walla Valley for weeks now, but the signs are just now appearing on our grapes. There are a few reasons that we see this difference. The first reason is the grape varieties that we grow: Cabernet Sauvignon, for example, takes a very long time to ripen. Vineyards that grow varieties such as Merlot, which ripens much more quickly, will see veraison earlier in August. Indeed, only our Syrah is showing signs of veraison. The Cabernet Sauvignon is usually two or three weeks behind!
The second reason that veraison occurs later for Walla Faces is because of the location of our vineyard. We are at a higher elevation than much of the Walla Walla Valley. Our vineyard is cooler during the Spring and Summer, but warmer during the end of summer, which helps give our wine a nice balance between sugars and acidity. (Our location also helps in autumn and winter. The warmer temperatures in cooler months help protect our grapes from freezing!)
In addition to being one of the later vineyards to see veraison, we are also one the last to harvest! This means we have many more weeks to admire our ripening grapes.
