Limoux wine is produced around the city of Limoux in Languedoc in southwestern France. Limoux wine is produced under four Appellation d'origine contrôlée (AOC) designations: Blanquette de Limoux, Blanquette méthode ancestrale, Crémant de Limoux and Limoux, the first three of which are sparkling wines and dominate the production around Limoux. The main grape of the region is the Mauzac, locally known as Blanquette, followed by Chardonnay and Chenin blanc. In 2005, the Limoux AOC was created to include red wine production consisting of mostly Merlot. Local wine historians believe that the world's first sparkling wine was produced in this region in 1531, by the monks at the abbey in Saint-Hilaire.
Climate and geography 
The Limoux wine region is located in the eastern foothills of the Pyrénées in southern France, south of the fortified city of Carcassonne. The classified vineyards are all in the Aude département, in the general vicinity of Limoux, west of the Corbières hills. The climate is dominated by the strong winds of the region, the dry, Atlantic vent cers and the warm, Mediterranean vent marin. The Mediterranean climate of the region has more Atlantic influences than other Languedoc wine regions. The soil in the area is rocky with clay, sandstone and limestone, creating distinct terroir throughout the region depending on the degree of Mediterranean or Atlantic influences and clay composition in the soil.
The unique topography of the region and combination of Mediterranean and Atlantic influences has created ideal conditions for the slow, even ripening of the region's white wine grapes. Despite being located at a southerly latitude, the climate is cooler and moister than in most of the wine regions in southern France. Its location in the foothills of the Pyrénées allows the vineyards to be at a higher elevation, and planted in optimal locations on hillsides.
Records show that Livy traded in non-sparkling white wines from Limoux as far back as the Roman occupation of the region.
Blanquette de Limoux is considered to be the first sparkling white wine produced in France, created long before the Champagne region became world renowned for the sparkling wine Champagne. The first textual mention of "blanquette", from the Occitan expression for "the small white", appeared in 1531 in papers written by Benedictine monks at an abbey in Saint-Hilaire. They detail the production and distribution of Saint-Hilaire's blanquette in cork-stoppered flasks. The region's location, north of the Cork Oak forest of Cataluña, gave Limoux producers easy access to the material needed to produce secondary fermentation in the flask, which produces the bubbles necessary for sparkling wine.
Local lore suggests that Dom Pérignon invented sparkling white wine while serving in this Abbey before moving to the Champagne region and popularizing the drink, but this is almost certain to be false since Dom Pérignon was involved with improving Champagne's still wines, and not the sparkling ones.
In 1938, Blanquette de Limoux became the first AOC established in the Languedoc region. While the classification is recent, the wine itself has long been a traditional apéritif or dessert accompaniment in the area.
In recent decades, appellation rules have been relaxed to allow an increased use of international grape varieties, which have partially replaced Mauzac.
The main grape of the Limoux region is the Mauzac grape, which produces a rustic wine with a characteristic apple-peel flavor that can be reminiscent of sweet apple cider. The grape is declining in worldwide plantings, with Southwest France being one of the few places where Mauzac has a lasting presence. The use of Chardonnay and Chenin blanc is growing, due in part to the more internationally recognized flavors of both grapes. The 1980s saw an increase in the plantings and popularity of Chardonnay. Limoux winemakers began developing a unique style of still wines made from Chardonnay and fermented in oak barrels that were sold as Vin de pays. The reputation of these Chardonnay wines grew to where they are regarded as some of the best examples of French Chardonnay outside of Burgundy. Barrel samplings were featured at the yearly Toques et Clochers charity auction that was modeled after the famous Hospices de Beaune. Prices of these Vins de pays soon exceeded what the French authorities thought was appropriate for this low classification and in 1993, the Limoux AOC was revised to include the still wines made from Chardonnay. While made mostly of Chardonnay, these wines are permitted to include Chenin blanc and must include a minimum of 15% Mauzac.
The red wines of the Limoux AOC are composed of at least 50% Merlot with Carignan, Grenache, Malbec (known locally as Côt) and Syrah making up at least 30% of the blend. Carignan itself is limited to a maximum of 10% as a component from the 2010 vintage. Cabernet Sauvignon and Cabernet Franc are also grown in the area and are restricted to a maximum of 20% together in red Limoux AOC wines. They are however also used in the Vin de pays wines sold as Vin de pays de la Haute Vallée de l'Aude.
Blanquette de Limoux 
The name Blanquette de Limoux has been used for a long time for the sparkling wines from Limoux. "Blanquette" actually just means "white" in the local Occitan language. Blanquette de Limoux can contain three grape varieties: Mauzac which must constitute a minimum of 90% of the wine, Chardonnay and Chenin blanc. Prior to the 1990 introduction of the Crémant de Limoux AOC, the use of Mauzac was optional. The change to the mandatory minimum of 90% Mauzac in the AOC regulations of Blanquette de Limoux was seen as a safeguard in maintaining the traditional style of Blanquette de Limoux and preserving the use of the local Mauzac grape which is declining in worldwide plantings. The taste of this Mauzac based wine is unique, with apple flavors and distinctive aromas of fresh cut grass that can be identified in blind tastings. Wine writer Tom Stevenson notes a change in the profile of recent vintage with wines that are "developing finer, more flowery, autolytic aromas."
The grape varieties are vinified separately before being assembled and bottled. Just before bottling, a tirage is added to the blend so that a second fermentation will take place in the bottle. The carbon dioxide produced during this second fermentation is trapped in the bottle and gives the wine its effervescence. After nine months, the bottles are opened and disgorged before a final corking.
Blanquette méthode ancestrale 
The wine that the monks of St-Hilaire invented in 1531 was known as Vin de Blanquette and the méthode rurale wine became a separate AOC known as Blanquette méthode ancestrale. Today this AOC is used for a sweetish sparkling wine made in a more old-fashioned way, without disgorgement. It is produced in the same area as Blanquette de Limoux, and may only contain Mauzac. Due to the absence of disgorgement, these wines are generally very cloudy with particles of the sediment of dead yeast cells, known as lees, still present in the wine. The winemaking method used to make Blanquette méthode ancestrale is also known as the méthode gaillacoise and is used to make the sparkling Mousseux wine of the Gaillac AOC. This method involves traditional hand crafted winemaking, with minimum use of modern technology such as stainless steel fermentation tanks. The resulting wines are typically low in alcohol (often less than 7% by volume), with sweet apple-like flavors and a slight sparkling fizz.
Bottling of this wine traditionally occurred on a day of astrological significance.
Crémant de Limoux 
When the term Crémant was introduced for non-Champagne sparkling wines in France, an AOC for more "modern" or internationally-styled sparkling wines, was created in 1990. The origin of that decision occurred a year earlier, in 1989, when the producers of Limoux had to decide whether or not they wanted to maintain the traditional makings of Blanquette de Limoux based on Mauzac or relax the AOC regulations to allow the introduction of more Chenin blanc and Chardonnay to create internationally recognized flavors. Limoux producers were split on what direction they wanted to go, so the provisional appellation of Crémant de Limoux was introduced to allow the producers to make whichever style of sparkling wine that they preferred and still sell it under an AOC designation. A deadline was set in 1994 for the least used AOC designation to be phased out but the deadline passed without Crémant de Limoux or Blanquette de Limoux making significant progress and both AOC continue to co-exist today. These Crémant de Limoux wines differ primarily from Blanquette de Limoux in their grape composition with Chardonnay and Chenin blanc as the main varieties. Together they are not to exceed 90% of the wines. For Chenin blanc, a minimum of 20% and a maximum of 40% must be used. Mauzac and Pinot noir are accessory grape varieties and may not exceed 20% together with Pinot noir itself not exceeding 10%. Thus, Crémant de Limoux contains 40-70% Chardonnay, 20-40% Chenin blanc, 10-20% Mauzac and 0-10% Pinot noir. AOC regulations dictate that the wine be aged for a least a year on the lees prior to disgorgement. Over 40 villages around the city of Limoux are permitted to make Crémant de Limoux.
Prior to 1993, the only non-sparkling still wine that Limoux producers could make under an AOC designation was Mauzac. The growing popularity and high prices of Vin de pays still wines made from Chardonnays prompted the French authorities to revise the Limoux appellation. Varietal versions of Chardonnay and Chenin blanc were permitted but all white wines were required to contain a minimum 15% of Mauzac. European Union regulations dictate that a varietal wine must contain at least 85% of the variety listed on the wine label so most Limoux AOC white wines are typically two grape blends-85% of the main variety, like Chardonnay, and 15% Mauzac. Producers that wished to make a 100% Chardonnay wine, or one without Mauzac, have to produce their wines as Vin de Pays d'Oc with E & J Gallo Winery's Red Bicyclette being one of the more notable examples being made primarily with Chardonnay grapes from the Limoux region. The Limoux AOC was the first AOC to regulate mandatory barrel fermentation for its white wine.
The appellation was approved for the production of red varietal wines starting with the 2003 vintage. These wines must contain a minimum of 50% Merlot with Grenache, Malbec and Syrah. Carignan is permitted at a maximum of 10% of the blend until 2010 when the variety is expected to be phased out completely of Limoux production. All together there must be at least 3 grape varieties in the blend with no two single varieties exceeding 90% of the total blend. In recent years, the Limoux AOC has seen significant investment by negociants, cooperatives and larger French wine estates, like Baroness Philippine de Rothschild of Château Mouton Rothschild, who see potential in the red wines from this traditionally sparkling white wine region.
Grape composition 
The AOC specifies the following rules for the varietal composition for Limoux AOC wine:
- White wine can be made from Mauzac, Chardonnay and Chenin blanc, with a minimum of 15% Mauzac.
- Red wine can be made from Merlot, Cabernet Franc, Cabernet Sauvignon, Grenache, Malbec (under the name Cot), Syrah and Carignan. The wine must be a blend containing a minimum of three varieties, with no two varieties together exceeding 90% of the blend. Furthermore, Merlot must make up a minimum of 50%, Grenache, Malbec, Syrah and Carignan must together make up a minimum of 30%. However, from the 2010 harvest, Carignan may not exceed 10%.
Wine styles 
The white still wines of the Limoux AOC vary depending on the primary grape. Mauzac adds a zesty acidity and requires time in the bottle before some of the more subtle, floral flavors emerge. Wines that are dominated by Chardonnay are more approachable in their youth and are tend to have a rich, full body with lemon and oak flavors.
