About this WINE
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.

A noble black grape variety grown particularly in the Northern Rhône where it produces the great red wines of Hermitage, Cote Rôtie and Cornas, and in Australia where it produces wines of startling depth and intensity. Reasonably low yields are a crucial factor for quality as is picking at optimum ripeness. Its heartland, Hermitage and Côte Rôtie, consists of 270 hectares of steeply terraced vineyards producing wines that brim with pepper, spices, tar and black treacle when young. After 5-10 years they become smooth and velvety with pronounced fruit characteristics of damsons, raspberries, blackcurrants and loganberries.
It is now grown extensively in the Southern Rhône where it is blended with Grenache and Mourvèdre to produce the great red wines of Châteauneuf du Pape and Gigondas amongst others. Its spiritual home in Australia is the Barossa Valley, where there are plantings dating as far back as 1860. Australian Shiraz tends to be sweeter than its Northern Rhône counterpart and the best examples are redolent of new leather, dark chocolate, liquorice, and prunes and display a blackcurrant lusciousness.
South African producers such as Eben Sadie are now producing world- class Shiraz wines that represent astonishing value for money.
