Napa’s Nested AVAs: Stag’s Leap
"There is a thread that connects these wines and it is the Stag's Leap regional personality. All the wines have velvety texture - a lushness that is nicely balanced by a firm acidity. They are big without being clumsy and awkward"
- Anthony Dias Blue, The Tasting Alliance
The history of viticulture in Stags Leap goes back to 1878. Terill L. Grigsby established the area's first winery called Occidental Winery. Then, in 1893, entrepreneur Horace Chase built the first winery in the area to bear the Stags Leap name. By the mid 1890's, Chase's winery was producing over 40,000 gallons of wine per year, but then came Phylloxera and then Prohibition, which caused most of the area farmers to convert their vineyards to orchards. In the early 1960's, a resurgence of winegrowing began when Nathan Fay planted the area's first Cabernet Sauvignon vineyard. Then, in 1976 at a blind tasting held in Paris, Stag's Leap Wine Cellars was awarded first place in a competition against renowned French wine producers. In 1989, the Stags Leap District was officially designated as an American Viticultural Area. Since then, the area has continued to be renowned as one of Napa Valley's finest sub-appellations.
Stags Leap District is an American Viticultural Area located within Napa Valley, about six miles north of the City of Napa. Considered to be a valley within a valley, Stags Leap District is located between the Stags Leap Palisades on the east side and the Napa River on the west. The Stags Leap District covers an area that is three miles long and one mile wide, with over half of its 2700 acres planted to grapevines and almost 70% of those Grapes are Cabernet Sauvignon.
Stags Leap District wines are known for being an “iron fist in a velvet glove.” The wines are like this for several reasons. First of all, this area is low in the valley so has regular access to breezes and fog from the San Pablo Bay which makes for a cooler environment. Secondly, the knolls and the Palisades work to form a wind tunnel. Above a certain mph, wind will actually shut down the vine and thereby slow photosynthesis and ripening. This extends the growing season considerably. The region’s soils are a mix of sandstone, shale, gravelly loam and volcanic material. It is home to one of east Napa Valley’s few alluvial fans and is the only valley floor appellation to not extend the full width of the valley. Cabernet Sauvignon is the dominant grape here and the wines tend to be soft with plush fruit and ripe tannins, but a sometimes strident acidity.
The rocky hillsides of the Stags Leap Palisades reflect heat and cause the vineyards to grow hotter more quickly than other areas in Napa Valley, but in the evening the cooling, marine breeze from San Pablo Bay sweeps through like a funnel. The nighttime cooling breeze from San Pablo Bay and surrounding hills produces lower overnight temperatures which allows grapes to achieve a desirable balance of acid and sugar. These conditions produce a longer growing season of warm days and cooler nights, which is beneficial to the cultivation of late-maturing grape varietals such as Cabernet Sauvignon.
