Muscadet
Muscadet is a French white wine. It is made at the western end of the Loire Valley, near the city of Nantes in the Pays de la Loire region. It is made from the Melon de Bourgogne grape, often referred to simply as melon. While most appellation d'origine contrôlée wines are named after their growing region, or in Alsace after their variety, the name Muscadet refers to an alleged characteristic of the wine produced by the melon grape variety: vin qui a un goût musqué. However, according to wine expert Tom Stevenson, Muscadet wines do not have much, if any, muskiness or Muscat-like flavors or aromas.
The sole variety used to produce Muscadet, Melon de Bourgogne, was initially planted in the region sometime in or before the 17th century. It became dominant after a hard freeze in 1709 killed most of the region's vines. Dutch traders, who were major actors in the French wine trade, encouraged the planting of this variety; they distilled much of the wine produced into eau de vie for sale in Northern Europe.
The generic Muscadet appellation, officially established in 1937, contains three regional sub-appellations:
- Muscadet-Sèvre et Maine, officially established in 1936, covering 20,305 acres with 21 villages in the Loire-Atlantique department and 2 in the Maine-et-Loire department. This appellation produces 80% of all Muscadets.
- Muscadet-Coteaux de la Loire, officially established in 1936, covering 467 acres with 24 villages spread across the Loire-Atlantique and Maine-et-Loire departments.
- Muscadet-Côtes de Grandlieu, officially established in 1994, benefits from the Grandlieu lake's microclimate. This sub appellation covers 717 hectares with 17 villages in the Loire-Atlantique department and 2 villages in the Vendée department.
History
The exact origins of Muscadet wine, and its association with the Melon de Bourgogne grape, is not clear. One estate near Nantes, Château de la Cassemichère, claims that the first Melon de Bourgogne vines used to make Muscadet were transported from Burgundy and planted in their vineyards in 1740. However, most ampelographers believe that the Melon de Bourgogne grape was introduced to the Pays Nantais region in the 17th century by Dutch trader looking for a sufficient source of neutral, white wines that could be distilled into brandewijn. Following the deep freeze of 1709, most of the red grape varieties were severely damaged and replaced by the hardier Melon de Bourgogne. The French ampelographer Pierre Galet found evidence that following that deep freeze, King Louis XIV ordered the replanting himself with a grape called Muscadent blanc that was most likely the Melon de Bourgogne.
By the 20th century, Muscadet began to fall out of favor in the global wine market and earned a reputation for being homogenous and simple. The late 20th century saw a revival in the Muscadet region as ambitious wine producers experimented with new winemaking techniques aimed at bringing out more flavor and complexity in the wine. The 1980s saw a rise in use of oak barrel fermentation and lees stirring while the 1990s introduced the widespread use of extended skin-contact prior to fermentation. By the 20th century, the use of these techniques created a wide range of styles and quality of Muscadet wine.
Climate and geography
The Muscadet growing region lies at the far western reaches of the Loire Valley and is dominated by maritime influences of the nearby Atlantic Ocean. The ocean's influence makes the climate of the Muscadet region cooler than the rest of the Loire Valley with more precipitation. Wine expert Tom Stevenson notes that the city of Nantes serves as a shield, protecting the region from northwesterly winds. However the closest vineyards to the city in the village of Vertou are located over 9.5 km from the city center and at higher elevation. Winters have the potential to be harsh with deep freezes common and threatening all the way into early spring.Vineyards in the Muscadet region are scattered across a wide range of terroirs ranging from gentle slopes near the rivers to rolling hills to flat fertile land near the mouth of the Loire river. The most ideally situated vineyards are in the rolling hills Muscadet-Sèvre et Maine sub-appellation located south and east of Nantes. The soil in this area is rich in magnesium and potassium, made up of clay, gravel and sand above subsoils of gneiss, schist, granite and volcanic rock. Throughout the Muscadet region the soils drain well, which is a necessity in a region as damp as the Pays Nantais. In the broader, generic Muscadet AOC the soil is predominantly silt and sand while the soils of the Muscadet-Coteaux de la Loire has high concentration of schist and the Muscadet-Côtes de Grandlieu sub-appellation has a mixture of granite and schist based soils.
Appellations
There are four main appellations of the Muscadet region. At the lowest level is the umbrella AOC Muscadet which covers the entire 32,000 acre region. Wine expert Jancis Robinson notes that wines carrying this basic designation are normally the most simple examples of Muscadet. Since the late 1990s, this level has been excluded from using sur lie aging by AOC regulations. Next come the three sub-appellations representing different micro-climates of the region: Muscadet-Sèvre et Maine; Muscadet-Coteaux de la Loire, which includes the northern most expanse of the area; and Muscadet-Côtes de Grandlieu, which is located in the southwestern area around the eponymous lake. As the most northern sub-appellation, the quality of wines from the Muscadet-Coteaux de la Loire can vary greatly depending on the vintage. In cooler years the grapes struggle to ripen and tend not to have the fruit to balance the acidity. In warmer years, this area tends to produce the most balanced wines. Muscadet-Côtes de Grandlieu is the most recent AOC promotion, gaining its status in 1996. Prior to gaining its own sub-appellation, this region was responsible for nearly three-quarters of the wine labeled as basic Muscadet AOC. Well made examples from Muscadet-Côtes de Grandlieu are characterized by floral bouquet and minerality.The Muscadet-Sèvre et Maine sub-appellation is the most productive and notable region of Muscadet, producing more than three-quarters of the region's entire production. In fact, more AOC Muscadet-Sèvre et Maine is produced on a yearly basis than in any other single AOC in the entire Loire Valley. The appellation is located east and south around the city of Nantes and is named after the rivers Sèvre and Maine that flow through it. Vineyard soil composition varies throughout the region and can range from the granite and schist hillsides around the village of Saint-Fiacre-sur-Maine to the predominantly clay based soils of Vallet. The most ideally situated vineyards are located around the villages of La Chapelle-Heulin, St-Fiacre, Vallet and Vertou Around 45% of the wine made Muscadet-Sèvre et Maine is aged sur lie. The wines made in this style tend to be slightly fuller body and can have some of the texture and mouthfeel of a white Bourgogne AOC. Well made examples will have a balance of fruit, acidity and texture.
Viticulture
The most common viticultural hazards in the Muscadet region are seasonal frost and mildew near harvest. The Melon de Bourgogne has adapted well to these condition being very frost resistant and capable of ripening early. Harvest usually takes place in mid to late September but in recent years producers have been experimented with harvesting the grapes several days to a couple weeks later. The traditional method is to harvest early in order to maintain acidity that is a key characteristic of Muscadet wine. The trend to pick later, and risk the threat of rains and mildew rot, is to give the grapes more time to develop sugars and riper phenols that can impart more fruit notes and complexity to the wine. However, these grapes that are picked later will usually experience a dramatic drop in acidity.Winemaking
The grape variety used to produce Muscadet, Melon de Bourgogne, is a relatively neutral grape. Winemaking techniques have evolved in the region to adapt to the grape's limitation and bring out more flavor and complexity. The most well-known of these techniques is sur lie aging, where the wine stays in contact with the dead yeast cells left over after fermentation. The technique was discovered, almost accidentally, in the early 20th century. Traditionally Muscadet producers would set aside a barrel of wine for special occasions, such as a family wedding. This "honeymoon barrel", as it became known, would take on more flavor and texture due to its contact with the lees. Through this process, autolysis occurs which contributes to a creamy mouthfeel that may make the wine seem to have a fuller body. The release of enzymes during this process inhibits oxidation which may also improve the aging potential of the wine. During this process, the wine is usually not racked for several months. While in many wines, the lack of racking could have the undesired consequences of developing off flavors or other wine faults. However, the relative neutrality of the Melon de Bourgogne grape works in the favor of the Muscadet wine and poses minimal risk to developing off flavors.The late 20th century saw a wave of winemaking innovation and the popularization of several winemaking techniques. The mid-1980s saw increased usage of oak barrels for fermentation over stainless steel fermenting tanks. The process of stirring the lees also became more commonplace. By stirring the lees, the dead yeast come into greater contact with the wood-based tannins and pigments that are usually extracted into the wine. The lees act as a sort of buffer between the wines and the oak elements, allowing the wine to maintain its color and not become too harsh and tannic. In the late 1990s, more Muscadet producers started extending the amount of time that the must spends in contact with the grape skins prior to fermentation. This extended maceration allowed the wine to leach more phenolic compounds from the skin which can add complexity to the wine.
Muscadet wines are usually bottled in the spring or autumn following the vintage though they can be made in the vins de primeur style and be released as early as the third Thursday of November. At time of bottling some carbon dioxide may still be present in the wine, giving it a slight effervescence that can come across as a "prickly" sensation to the tongue. This effervescence is rarely seen to the degree of a semi-sparkling wine such as Lambrusco. Under French AOC regulations, the maximum alcohol content of a Muscadet must be no more than 12% -making it the only unfortified French wine to have a maximum alcohol content stipulation.
