Sauvignon blanc is a green-skinned grape variety that originates from the Bordeaux region of France. The grape most likely gets its name from the French words sauvage ("wild") and blanc ("white") due to its early origins as an indigenous grape in South West France. It is possibly a descendant of Savagnin. Sauvignon blanc is planted in many of the world's wine regions, producing a crisp, dry, and refreshing white varietal wine. The grape is also a component of the famous dessert wines from Sauternes and Barsac. Sauvignon blanc is widely cultivated in France, Chile, Romania, Canada, Australia, New Zealand, South Africa, the states of Washington and California in the US. Some New World Sauvignon blancs, particularly from California, may also be called "Fumé Blanc", a marketing term coined by Robert Mondavi in reference to Pouilly-Fumé.
Depending on the climate, the flavour can range from aggressively grassy to sweetly tropical. In cooler climates, the grape has a tendency to produce wines with noticeable acidity and "green flavours" of grass, green bell peppers and nettles with some tropical fruit (such as passion fruit) and floral (such as elderflower) notes. In warmer climates, it can develop more tropical fruit notes but risk losing a lot of aromatics from over-ripeness, leaving only slight grapefruit and tree fruit (such as peach) notes.
Wine experts have used the phrase "crisp, elegant, and fresh" as a favourable description of Sauvignon blanc from the Loire Valley and New Zealand. Sauvignon blanc, when slightly chilled, pairs well with fish or cheese, particularly chèvre. It is also known as one of the few wines that can pair well with sushi.
Along with Riesling, Sauvignon blanc was one of the first fine wines to be bottled with a screwcap in commercial quantities, especially by New Zealand producers. The wine is usually consumed young, as it does not particularly benefit from aging, as varietal Sauvignon blancs tend to develop vegetal aromas reminiscent of peas and asparagus with extended aging. Dry and sweet white Bordeaux, including oak-aged examples from Pessac-Léognan and Graves, as well as some Loire wines from Pouilly-Fumé and Sancerre are some of the few examples of Sauvignon blancs with aging potential.
