Edmunds St. John Heart of Gold 2013
As home to California’s highest altitude vineyards, El Dorado is also one of its oldest wine growing regions. When gold miners settled here in the late 1800s, many also planted vineyards and made wine to quench its local demand.
By 1870, El Dorado County, as part of the greater Sierra Foothills growing area, was among the largest wine producers in the state, behind only Los Angeles and Sonoma counties. The local wine industry enjoyed great success until just after the turn of the century when fortune-seekers moved elsewhere and its population diminished. With Prohibition, winemaking and grape growing was totally abandoned. But some of these vines still exist today and are the treasure chest of the Sierra Foothills as we know them.
El Dorado has a diverse terrain with elevations ranging from 1,200 to 3,500 feet, creating countless mesoclimates for its vineyards. This diversity allows success with a wide range of grapes including whites like Gewurztraminer and Sauvignon Blanc, as well as for reds, Grenache, Syrah, Tempranillo, Barbera and especially, Zinfandel.
Soils tend to be fine-grained volcanic rock, shale and decomposed granite. Summer days are hot but nights are cool and the area typically gets ample precipitation in the form or rain or snow in the winter.
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, 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 wine 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.
