Merlot blanc

Last updated

Merlot blanc is a white French wine grape variety that came from a natural crossing of the Bordeaux wine grape Merlot and the Cognac grape Folle blanche. [1] The grape is distinct from Merlot gris which is a pink-skinned color mutation of the red wine grape Merlot and is sometimes used in vin gris and rosé wines. Plantings of Merlot blanc were first discovered in 1891 but cuttings of the vine have not been widely propagated and the variety is very rare. It is not used to make the sweet White Zinfandel-style wine White Merlot that is made by some California wine producers. Those wines are made from a saignee of red Merlot wine. [2]

When Merlot blanc was first discovered, it was thought that the vine was a white-berried color mutation of Merlot in a similar relation to how Grenache blanc is a color mutation of Grenache and Pinot blanc is a mutation of Pinot noir. However, DNA analysis conducted by the University of California-Davis and noted ampelographers such as Carole Meredith confirmed that Merlot blanc was distinct from Merlot (itself the result of a crossing of the Bordeaux grape Cabernet Franc and the Brittany/Charente grape Magdeleine Noire des Charentes) but rather was an offspring of Merlot. Inheritance analysis of 55 genetic markers spread out over 9 chromosomes, showed that Merlot blanc was the result of a crossing of Merlot with the Cognac/Armagnac grape Folle blanche. [1] [2]

Wine regions

Even though plantings of Merlot blanc are scarce, the grape is still a permitted a variety in the Appellation d'origine contrôlée (AOC) wines of several Bordeaux wine regions including the general AOC Bordeaux (but not for wines labeled Bordeaux Supérieur). Here Merlot blanc can be used in up to 30% of the blend along with Semillon (which must make up at least 70% of the blend itself), Sauvignon blanc, Muscadelle, Colombard, Mauzac, Ondenc and Ugni blanc. Merlot blanc destined for AOC wine production are limited to harvest yields no greater than 55 hl/ha (approximately 3.7 tons/acre with the finished wines needing to attain a minimum alcohol level of at least 11%. [3]

Other Bordeaux AOCs that permit the usage of Merlot blanc in their designated white wines include Bordeaux-Haut-Benauge (maximum harvest yield of 50 hl/ha), Côtes de Bourg (but not the Côtes de Blaye) and Entre-Deux-Mers (which like the Côtes de Bourg limits harvest yield to 60 hl/ha). In all these AOCs Merlot blanc plays a supporting role to Semillon, Sauvignon blanc and Muscadelle. [3]

Synonyms

Over the years Merlot blanc has been known under a variety of synonyms including: Merlau blanc, Merlaut blanc and Merlot bianco. [4]

Merlot wine grape variety

Merlot is a dark blue–colored wine grape variety, that is used as both a blending grape and for varietal wines. The name Merlot is thought to be a diminutive of merle, the French name for the blackbird, probably a reference to the color of the grape. Its softness and "fleshiness", combined with its earlier ripening, makes Merlot a popular grape for blending with the sterner, later-ripening Cabernet Sauvignon, which tends to be higher in tannin.

Carignan Red wine grape variety

Carignan is a red grape variety of Spanish origin that is more commonly found in French wine but is widely planted throughout the western Mediterranean and around the globe. Along with Aramon, it was considered one of the main grapes responsible for France's wine lake and was a substantial producer in jug wine production in California's Central Valley but in recent years, it has been reborn as a flagship wine for many cellars in the south of France as well as in Catalonia.

Folle blanche Variety of grape

Folle blanche, also known as Picpoule, Gros Plant, and Enrageat blanc, is a wine grape variety from southwest France. It was the traditional grape variety in Cognac and Armagnac production until the 20th century. Folle blanche is an offspring of Gouais blanc, with the other parent so far unidentified.

Sémillon Variety of grape

Sémillon is a golden-skinned grape used to make dry and sweet white wines, mostly in France and Australia. Its thin skin and susceptibility to botrytis make it dominate the sweet wine region Sauternes AOC and Barsac AOC.

Bordeaux wine Wine produced in the Bordeaux region of France

Bordeaux wine is any wine produced in the Bordeaux region of southwest France. Bordeaux is centered on the city of Bordeaux, on the Garonne River. To the north of the city the Dordogne River joins the Garonne forming the broad estuary called the Gironde and covering the whole area of the Gironde department, with a total vineyard area of over 120,000 hectares, making it the largest wine growing area in France.

Muscadelle White wine grape variety

Muscadelle is a white wine grape variety. It has a simple aroma of grape juice and raisins like grapes of the Muscat family of grapes, but it is unrelated.

Pineau d'Aunis is a red French wine grape variety that is grown primarily in the Loire Valley around Anjou and Touraine.

Terret noir Variety of grape

Terret noir is a dark-skinned French wine grape variety grown primarily in the Rhône valley region of France. It is a mutation of the old Vitis vinifera vine Terret. It is a permitted blending grape for Châteauneuf-du-Pape. Like the related Terret gris and Terret blanc, the vine tends to bud late and grow vigorously. Terret noir produces a light color wine that is perfumed and tart.

Bordeaux wine regions

The wine regions of Bordeaux are a large number of wine growing areas, differing widely in size and sometimes overlapping, which lie within the overarching wine region of Bordeaux, centred on the city of Bordeaux and covering the whole area of the Gironde department of Aquitaine.

Grenache blanc Variety of grape

Grenache blanc is a variety of white wine grape that is related to the red grape Grenache. It is mostly found in Rhône wine blends and in northeast Spain. Its wines are characterized by high alcohol and low acidity, with citrus and or herbaceous notes. Its vigor can lead to overproduction and flabbiness. However, if yields are controlled, it can contribute flavor and length to blends, particularly with Roussanne. Since the 1980s, it has been the fifth most widely planted white wine grape in France after Ugni blanc, Chardonnay, Semillon and Sauvignon blanc.

Mouton Cadet is the brand name of a popular range of modestly priced, generic Bordeaux wines, considered Bordeaux's most successful brand. Created by Baron Philippe de Rothschild, Mouton Cadet wine is produced through the assembly of a variety of grapes, from several Bordeaux region appellations.

Regional Bordeaux AOCs

In the Bordeaux wine region there are seven regional Appellations d'origine contrôlée (AOCs) that may be used throughout the Gironde department. These are Bordeaux Rouge AOC, Bordeaux Supérieur Rouge, Bordeaux Clairet, Bordeaux Rosé, Bordeaux Blanc, a dry white, Bordeaux Supérieur Blanc, a sweet white, and Crémant de Bordeaux, a sparkling méthode traditionnelle wine. The regional appellations together form the largest world-class wine vineyard, making up more than half of the production of the prestigious Bordeaux wine region, and representing more than 55% of all Bordeaux wines consumed in the world.

Côtes du Marmandais is an Appellation d'origine contrôlée (AOC) for wine located in South West France around the commune of Marmande. With its location just southeast of the Entre-Deux-Mers along the banks of the Garonne river, it is a satellite of Bordeaux, but just outside the borders of that region. The region was elevated from Vin Délimité de Qualité Superieure (VDQS) to AOC status in 1990. From the Middle Ages to the 19th century, the wines of the Côtes du Marmandais were widely exported to the Netherlands. The Phylloxera epidemic wiped out most of the vineyards in this area with many farmers switching to other agricultural crops. It was not until the later half of the 20th century that viticulture in the area reaffirmed itself.

Provence wine

Provence (Provençal) wine comes from the French wine-producing region of Provence in southeast France. The Romans called the area provincia nostra, giving the region its name. Just south of the Alps, it was the first Roman province outside Italy.

South West France (wine region)

South West France, or in French Sud-Ouest, is a wine region in France covering several wine-producing areas situated respectively inland from, and south of, the wine region of Bordeaux. These areas, which have a total of 16,000 hectares of vineyards, consist of several discontinuous wine "islands" throughout the Aquitaine region, and more or less to the west of the Midi-Pyrénées region.

Côtes de Bourg

Côtes de Bourg is an Appellation d'origine contrôlée (AOC) for Bordeaux wine situated around the small town of Bourg-sur-Gironde near Bordeaux, France. The first vineyards in the area were founded by the Romans. In the Middle Ages, Bourg was a major port for wine and the vineyards developed at the same tempo as the estuary traffic. The Côtes de Bourg appellation, in the north of the patchwork of Bordeaux wines, took its first steps on the east bank of the Gironde. At the time, the inhabitants of Bourg were fishermen, sailors or winemakers and the latter benefited from the perfect combination of a commercially minded town and a soil made for the vine.

Cadillac AOC

Cadillac is an Appellation d'Origine Contrôlée (AOC) for sweet white wine from the Bordeaux wine region in France. It is located within the Entre-Deux-Mers subregion of Bordeaux. It takes its name from the town of Cadillac.

Côtes de Duras

Côtes de Duras is an Appellation d'Origine Contrôlée (AOC) for red and white wines in South West France. Côtes de Duras is located in the department of Lot-et-Garonne, and is located immediately adjacent to the Bordeaux wine region, which is restricted to the Gironde department, as an extension of Bordeaux immediately to the east of the departmental border.

Calitor Variety of grape

Calitor or Calitor noir is a red French wine grape variety. It was previously widely cultivated in southern France, in particular in Provence, but is now very rare, almost extinct. Historically used as mainly a blending variety, Calitor gives high yields and produces a light-bodied and lightly colored wine. When grown on hillside sites, it can give a wine of character.

Canari noir is a red French wine grape variety that has been historically grown in the Ariège department in the foothills of the French Pyrénées. However DNA profiling in 2001 showed that plantings of a grape called Gamay Luverdon growing in the Italian wine region of Piedmont were in fact plantings of Canari noir. Across the Pyrénées in Spain, the grape variety known as Batista was also found to be identical to Canari noir. Like Pinot noir and Grenache, Canari noir has color mutations known as Canari blanc and Canari gris.
