French wine
French wine is produced in several regions throughout France, in quantities between 50 and 60 million hectolitres per year, or 7–8 billion bottles. France has the world's second-largest total vineyard area, behind Spain, and is in the position of being the world's largest wine producer...

History

The area around Sancerre was likely first cultivated by the Romans, perhaps in the 1st century AD, though the exact date is unknown. The chalk hill outcrop was not only a distinctive landmark known in Roman times but it also fit the profile of the type of areas that was usually the first to be cultivated-it was near an important town and had easy access to a navigable river. Most importantly, however, the steep sloping hills could provide the grapes with enough direct sunlight and warmth to fully ripen while allowing cold air to flow off the slope and pool into the valleys below.

The region was historically linked to the Duchy of Burgundy

Climate and geography

Sancerre is part of the "central vineyards" of the Loire Valley, so named not because they are in the center of the Loire but rather because they are nearly in the center of France. Together with neighboring Pouilly-Fumé, the region makes up the eastern most extension of the Loire Valley. The area is more than 300 miles (483 kilometers) from the Atlantic Coast

The most dominating geographical influence of Sancerre is the nearby Loire river which flows northward past the city before it curves westward at Orleans and makes it path to the ocean.

Most vineyards planted on the hills around Sancerre are on south facing slopes at altitudes between 655-1,310 feet (200–400 meters). The soils around the area can be roughly classified into three categories. The far western reaches heading towards Menetou-Salon have "white" soils with clay

Viticulture and winemaking

As a cool continental climate region, one of the main viticultural threats in Sancerre is springtime frost. Throughout most of the growing season the nearby Loire river to the east and forest to the west help moderate temperatures. Vine growers in the area tend to utilize cordon or single Guyot vine training and tailor their canopy management techniques to whichever style of Sauvignon blanc they are looking to produce. Grassy, herbaceous

s, the growers may need to take the additional measures of leaf plucking and de-budding in order to thin out the canopy and produce more fruit concentrated grapes.

The age of vine can also contribute to how much grassy character the resultant wine may have as well as how early the grapes are harvested. Many of the phenolic compounds and aroma compounds, such as pyrazine

, that contribute to strong grassy flavors are found in the grape skins, eventually breaking down as it goes through its ripening process. Grapes that are harvested before they are physiologically ripe may have more overt grassy notes. How the harvest is conducted will depend on where the vineyards are located. As the steep slopes on which many Sancerre vineyards are planted make mechanical harvesting difficult many vineyards are picked by hand. However, in the flatter vineyards located more towards the west of the appellation, mechanical harvesting is starting to become more prevalent.

The focus of Sancerre winemakers is usually to express the pure fruit flavors of Sauvignon blanc and the natural terroir of the region with very little adjustments taking place during winemaking. Most Sancerre is produced without malolactic fermentation
Malolactic fermentation
