California's El Dorado AVA: regional profile and wines to try

California's El Dorado AVA may help the state strike gold when it comes to crafting fresh wines from mountainous elevations. Located 180km east of St Helena in Napa Valley , the Sierra Foothills begin to rise out of the Sacramento Valley. Here, towns like Folsom and Placerville might not be associated with wine but are well-known all the same, thanks to singer Johnny Cash and the history of America’s gold rush. But dig a bit deeper and you'll find a wine region flourishing in these foothills, among California 's highest elevations for viticulture.

The migration to California and the hills and riverbeds around Placerville brought throngs of people hoping to strike it rich. They were also thirsty, so a wine industry flourished as early as 1870. At its peak, the vineyard acreage in the area that is now the El Dorado AVA (a sub-region of the vast Sierra Foothills AVA) was what it has returned to today: about 800ha. People eventually left as the riches never really materialised. The vines also withered along with those fantasies of striking gold, finally dying at the hands of America’s Prohibition. Mountain made A key industry in El Dorado is seasonal agriculture. Christmas trees are the big business, as well as pumpkin patches and autumn-harvested fruits like pears and apples. It is also along the highway to Lake Tahoe, so makes a popular country escape for those coming from Sacramento to the ski resorts or for summer recreation. [caption id="attachment_495376" align="alignnone" width="630"] The Boeger Winery still has producing vines that were planted in the Gold Rush era, as here in 1888.[/caption] El Dorado is also a wine region on the rise precisely because of its rugged, mountainous surroundings. In 1973 the Boeger family opened its eponymous winery, as did Madroña Vineyards, the two sparking the region’s rebirth. The region’s volcanic soils and elevation, with some vines planted at over 1,000m, offer the potential to create wines with great acidity and freshness. The foothills are steep, with plenty of slope and aspect variation. Within a few metres, one vineyard block may be north-facing and another facing south. These growing conditions, unique in California, create opportunities and challenges that some of the region's most talented winemakers are embracing. [breakout] El Dorado AVA at a glance Location A sub-appellation of the larger Sierra Foothills AVA, considered the Sierra Foothills Highlands for its high-elevation vineyards. It is one hour's drive east of Sacramento, California's state capital, and one hour's drive west of Lake Tahoe. Elevation 360m to 1,070m Wineries 70 Area under vine 1,214ha Soils Diverse and shallow, mainly volcanic or granitic Grape varieties More than 70, 89% red Key red grapes Zinfandel, Cabernet Sauvignon, Syrah, Barbera Key white grapes Chardonnay, Marsanne, Viognier, Roussanne [/breakout] ‘While every region touts its unique terroir and microclimate, our greatest strength is that we have so many over such a small geographical area,’ says Justin Boeger, who makes the wines at the region’s founding winery. ‘We have diversity in the number of varietals we can grow in a way that, I believe, maximises their potential while also showing tremendous versatility of style and expression across single varietals. Our unique soil types and vineyard-specific climatic influences allow each of us to produce a different expression of the same grape for every varietal we have.’ Great heights Altitudes of 550m and above have a dramatic impact on the growth and maturation on El Dorado's vineyards. Bud break and flowering in the spring can be a month or more behind the vines planted at lower elevations. Ripening continues through the fall at much cooler temperatures, ensuring the grapes retain more acidity and sugar levels are lower. This delay, however, makes the vines more vulnerable to spring and autumn frosts. [caption id="attachment_496283" align="alignnone" width="630"] Edio Vineyards, where all the estate blocks are above 840m.[/caption] While California isn’t known as an alpine wine region, that is how Peter Delfino, winemaker at Edio Vineyards, sees the El Dorado AVA. ‘Most of our wines are grown at 380m or higher. Our estate vineyards are all above 840m. We truly are making mountain wines. ‘These are fresh and bright wines, and they can be quite complex, Delfino adds. 'This is primarily due to our mountainous terrain and elevation. The higher elevations expose the fruit to more intense UV light, which allows us to reach phenolic maturity at a lower potential alcohol while maintaining a higher acidity.’ This combination of high acidity and lower alcohol can be an overlooked stylistic element in El Dorado wines. Because of their location in the Sierra Foothills, they tend to be associated with the richer, riper wines made in nearby AVAs. This conflation can overshadow their unique character. Spice of life Variety is a hallmark of El Dorado. There has been some focus on Rhône styles, but several of the AVA's original producers, like Boeger, have found more success with Italian grapes. This diversity is both a strength for the region and a limiting factor in galvanising a sense of identity for consumers. ‘Back in 1973, as one of the earliest vineyards involved in the sort of "renaissance” of El Dorado, we planted varieties well-known in the market at the time,' says Paul Bush of Madroña Vineyards. 'The focus was on our wine being marketable, perhaps more than our terroir.' [caption id="attachment_496297" align="alignnone" width="630"] Paul Bush of Madroña Vineyards.[/caption] 'This included Chardonnay , Riesling and Gewürztraminer , for which the greater Sierra Foothills AVA were not known. The market was different before the Judgement of Paris . This foray into cooler-climate whites helped expand our understanding of what could be grown in the area.’ He continues: ‘It’s interesting that what I once felt were limitations may in fact be strengths in the future. Because El Dorado hasn’t had an individual variety to hang its hat on, it’s been difficult to market the region. ‘Yes it means that our reputation as a region has grown very slowly but, as late-bloomers, it gives us a chance to learn from the mistakes of other regions.’ As climate change creates challenges, the mountain wines coming from the El Dorado AVA have an opportunity to succeed in unique ways given their elevation and cool spring and autumn weather. As wines with higher acidity and lower phenolic ripeness gain in popularity, the producers focusing on fine wines from this region may just seize an opportunity to be California’s new kings of cool.
