2023 Quintessa, Illumination, California, USA

Quintessa

Quintessa is a single 75-hectare estate, belonging to the Franciscan Group, which lies in the heart of Rutherford. The estate includes a valley, a lake, a river and 5 hills with 5 distinct soil types. It is unique in the sheer diversity it encompasses. Valerie Huneeus, a scientist and viticulturist, has developed the vineyards from the ground up, utilising the latest vineyard technology.

Quintessa is an American Bordeaux blend or "meritage" comprising Cabernet Sauvignon (60%), Merlot (30%), and Cabernet Franc (10%). It is aged in small French barrels (75% new) for 18 months. The inaugural vintage was 1996 and already Quintessa is being talked of as a Californian classic.

Napa Valley

North Coast's Napa Valley is California's most famous viticultural area (AVA), claiming some of the most expensive agricultural land in the world and producing wines of ‘cult’ status.

Its 16,000 ha of vines lie over a strip (40 miles long-5 miles wide) of diverse soils (clay, gravely, volcanic), with its northernmost end on the side of Mountain Helena and its foot in San Francisco Bay. The valley is framed by two mountains ranges Vaca (to the north) and Mayacamas (to the south), yet the main climatic influence is the cool wind and fog that is sucked in from San Pablo Bay during the afternoon, allowing grapes to ripen slowly and evenly. 

The area enjoys a variety of unique microclimates, as temperatures can vary dramatically as much as 15 degrees, from the north to the south end of the valley. These differences have led to the creation of several sub-AVAs (14 in total) including:

Atlas Peak, Chiles Valley District, Diamond Mountain District, Howell Mountain, Los Carneros, Mt. Veeder, Oakville, Rutherford, St. Helena, Spring Mountain District, Stags Leap District, Yountville, Wild Horse Valley and Oak Knoll District. The Calistoga AVA is still pending approval.

Both the “Napa Valley” designation and the sub-AVA name must appear on the wine label simultaneously, with the exception of wines from the Carneros AVA, which is shared between the Napa Valley and the Sonoma County.

Cabernet Sauvignon is the undisputed king of Napa grapes, occupying over 45% of the vineyard acreage, followed by (predominantly) Chardonnay, Sauvignon Blanc, Chenin Blanc, Riesling, Zinfandel, Merlot, Cab. Franc and to a lesser extent Petite Sirah, Sangiovese, Barbera, Dolcetto.

Sauvignon Blanc & Sémillon

The blend used for White Graves and Sauternes and rarely encountered outside France. In the great dry whites of Graves, Sauvignon Blanc tends to predominate in the blend, although properties such as Smith Haut Lafite use 100% Sauvignon Blanc while others such as Laville Haut Brion have as much as 60% Sémillon in their final blends. Sauvignon Blanc wines can lose their freshness and fruit after a couple of years in bottle - if blended with Sémillon, then the latter bolsters the wine when the initial fruit from the Sauvignon fades. Ultimately Sauvignon Blanc gives the wine its aroma and raciness while Sémillon gives it backbone and longevity.

In Sauternes, Sémillon is dominant, with Sauvignon Blanc playing a supporting role - it is generally harvested about 10 days before Sémillon and the botrytis concentrates its sweetness and dampens Sauvignon Blanc`s naturally pungent aroma. It contributes acidity, zip and freshness to Sauternes and is an important component of the blend.
