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.
A region that has become synonymous with some of the best whites of Chile, the Casablanca Valley is full of dozens of bodegas who either grow fruit here or come from outside to source from local growers for their own white wine programs. The valley runs from east to west, which means that its westernmost vineyards receive the most cooling influence from the reliable afternoon sea breezes. The soils also tend to be heavier in clay in the west, whereas the eastern end of the valley is warmer and its soils are predominantly granitic. Sauvignon blanc thrives here, Chardonnay does well and Pinot noir is not uncommon.
