Winemaker Notes
A warm inland area just north of Napa Valley, Lake County represents a new frontier for California winemaking. While Prohibition halted viticulture here just as it did in so many California regions, winemaking activity remained fairly insignificant for a few decades longer than others. Finally in the 1990s Lake County Sauvignon blanc—uniquely savory and fruity—earned the appellation a renewed reputation.
Lake County is comprised of a handful of unique American Viticultural Areas (AVAs).
Vineyards that settle into the hills on the west side of Clear Lake create the Clear Lake AVA and produce good quality Cabernet Sauvignon, Sauvignon blanc and Zinfandel.
Recently the Red Hills AVA, located within the boundaries of the Clear Lake AVA, has become the focus of some of Napa’s more respected growers. Its notable volcanic and obsidian-based soils could be the source of California’s next best Cabernet Sauvignons. Andy Beckstoffer, a leader in recognizing prime Napa Valley vineyard locales, has already invested heavily in the area.
Guenoc Valley AVA produces fine examples of Petite Sirah, recognized for their voluptuous aromas of clove, cocoa, tobacco and deep red and blue berry flavors.
The High Valley AVA sits northeast of Clear Lake. This warm area boasts multiple soil types allowing growers a lot of flexibility and experimentation with grape varieties. While Sauvignon blanc is a mainstay, this zone excels with Zinfandel, Petite Sirah, as well as other less common varieties like Barbera and Tempranillo.
With hundreds of red grape varieties to choose from, winemakers have the freedom to create a virtually endless assortment of blended wines. In many European regions, strict laws are in place determining the set of varieties that may be used, 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 fruity and full-bodied wine would do well combined with one that is naturally high in acidity and tannins. 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.
