Along withCabernet Sauvignon,Cabernet Franc,Malbec, andPetit Verdot, Merlot is one of the primary grapes used inBordeaux wine, and it is the most widely planted grape in theBordeaux wine regions. Merlot is also one of the most popular red winevarietals in many markets.[2] This flexibility has helped to make it one of the world's most planted grape varieties. As of 2004, Merlot was estimated to be the third most grown variety at 260,000 hectares (640,000 acres) globally.[3]The area dedicated to Merlot has continued to increase, with 266,000 hectares (660,000 acres) in 2015.[4]
While Merlot is made across the globe, there tend to be two main styles. The "International style" favored by manyNew World wine regions tends to emphasize lateharvesting to gainphysiological ripeness and produce inky, purple-colored wines that arefull in body with high alcohol and lush, velvetytannins with hints of plum and blackberry. While this international style is practiced by manyBordeaux wine producers, the traditional "Bordeaux-style" of Merlot involves harvesting Merlot earlier. This maintains theacidity and produces more medium-bodied wines with moderate alcohol levels that have fresh, red fruit flavors (raspberries, strawberries) and potentially leafy, vegetal notes.[5]

The earliest recorded mention of Merlot (under the synonym ofMerlau) was in the notes of a localBordeaux official who in 1784 labeled wine made from the grape in theLibournais region as one of the area's best. In 1824, the wordMerlot itself appeared in an article onMédoc wine which mentioned that the grape was named after the localblack bird (calledmerlau in the local variant ofOccitan language,merle in standard French) who liked eating the ripe grapes on the vine. Other descriptions of the grape from the 19th century called the varietylou seme doù flube (meaning "the seedling from the river") with the grape thought to have originated on one of the islands found along theGaronne river.[1]
By the 19th century it was being regularly planted in theMédoc on the "Left Bank" of theGironde.[6] After a series of setbacks that included a severe frost in 1956 and several vintages in the 1960s lost to rot, French authorities in Bordeaux banned new plantings of Merlot vines between 1970 and 1975.[7]
It was first recorded in Italy aroundVenice under the synonymBordò in 1855. The grape was introduced to theSwiss, from Bordeaux, sometime in the 19th century and was recorded in the Swisscanton ofTicino between 1905 and 1910.[6] In the 1990s, Merlot saw an upswing of popularity in theUnited States. Red wine consumption, in general, increased in the US following the airing of the60 Minutes report on theFrench Paradox and the potentialhealth benefits of wine and, possibly, the chemicalresveratrol. The popularity of Merlot stemmed in part from the relative ease in pronouncing the name[clarification needed] of the wine as well as its softer, fruity profile that made it more approachable to some wine drinkers.[8]
Cabernet Franc, one of the parent varieties of Merlot.
In the late 1990s, researchers at theUniversity of California, Davis, showed that Merlot is an offspring ofCabernet Franc and is a half-sibling ofCarménère,Malbec, and Cabernet Sauvignon.[9] The identity of the second parent of Merlot wouldn't be discovered till the late 2000s when an obscure and unnamed variety, first sampled in 1996 from vines growing in an abandoned vineyard inSaint-Suliac inBrittany, was shown by DNA analysis to be the mother of Merlot.[1]
This grape, later discovered in front of houses as a decorative vine in the villages ofFigers,Mainxe,Saint-Savinien, andTanzac in thePoitou-Charentes, was colloquially known asMadeleina orRaisin de La Madeleine due to its propensity to be fully ripe and ready forharvest around the July 22ndfeast day ofMary Magdalene. As the connection to Merlot became known, the grape was formally registered under the nameMagdeleine Noire des Charentes. Through its relationship with Magdeleine Noire des Charentes, Merlot is related to theSouthwest France wine grapeAbouriou, though the exact nature of that relationship (with Abouriou potentially being either a parent of Magdeleine Noire or an offspring) is not yet known.[1]
Merlot grapes are identified by their loose bunches of large berries. The color has less of a blue/black hue than Cabernet Sauvignon grapes and with a thinner skin and fewer tannins per unit volume. It normally ripens up to two weeks earlier than Cabernet Sauvignon. Also compared to Cabernet, Merlot grapes tend to have a highersugar content and lowermalic acid.[7]AmpelographerJ.M. Boursiquot has noted that Merlot has seemed to inherit some of the best characteristics from its parent varieties—its fertility and easy ripening ability from Magdeleine Noire des Charentes and itscolor,tannin and flavorphenolic potential from Cabernet Franc.[1]
Merlot thrives in cold soil, particularlyferrousclay. The vine tends tobud early which gives it some risk to cold frost and its thinner skin increases its susceptibility to theviticultural hazard ofBotrytis bunch rot. If bad weather occurs duringflowering, the Merlot vine is prone to developcoulure.[10] The vine can also be susceptible todowny mildew (though it has better resistance topowdery mildew than other Bordeaux varieties) and to infection byleafhopper insect varieties.[1]
Water stress is important to the vine with it thriving in well-drained soil more so than at base of a slope.Pruning is a major component to the quality of the wine that is produced with some producers believing it is best to prune the vine "short" (cutting back to only a few buds). Wine consultantMichel Rolland is a major proponent of reducing theyields of Merlot grapes to improve quality.[6] The age of the vine is also important, with older vines contributing character to the resulting wine.[7]
A characteristic of the Merlot grape is the propensity to quickly overripen once it hits its initialripeness level, sometimes in a matter of a few days. There are two schools of thought on the right time toharvest Merlot. The wine makers ofChâteau Pétrus favor early picking to best maintain the wine'sacidity and finesse as well as its potential foraging. Others, such as Rolland, favor late picking and the added fruit body that comes with a little bit of over-ripeness.[6]
In places likeIsrael, Merlot is the second most widely planted grape variety after Cabernet Sauvignon with 1,000 hectares (2,500 acres) in cultivation, making very "New World-style" wines. The grape can also be found inTurkey (429 hectares (1,060 acres) in 2010),Malta, andCyprus.[1]
Merlot is the most commonly grown grape variety in France.[1] In 2004, total French plantations stood at 115,000 hectares (280,000 acres).[12] By 2017, that number had dropped slightly to 112,000 hectares (280,000 acres).[13] It is most prominent inSouthwest France in regions likeBordeaux,Bergerac, andCahors, where it is often blended with Malbec. The largest recent increase in Merlot plantations has occurred in the south of France, such asLanguedoc-Roussillon, where it is often made under the designation ofVin de Pays wine.[10] Here, Merlot accounted for 29,914 hectares (73,920 acres), more than doubling the 11,000 hectares (27,000 acres) devoted to Cabernet Sauvignon in the Languedoc.[1]
In the traditional Bordeaux blend, Merlot's role is to add body and softness. Despite accounting for 50-60% of overall plantings inBordeaux, the grape tends to account for an average of 25% of the blends—especially in theBordeaux wine regions ofGraves andMédoc. Of these Left Bank regions, the commune ofSt-Estephe uses the highest percentage of Merlot in the blends.[8] However, Merlot is much more prominent on the Right Bank of theGironde in the regions ofPomerol andSaint-Émilion, where it will commonly comprise the majority of the blend. One of the most famous and rare wines in the world,Château Pétrus, is almost all Merlot. In Pomerol, where Merlot usually accounts for around 80% of the blend, theiron-clay soils of the region give Merlot more of a tannic backbone than what is found in other Bordeaux regions. It was in Pomerol that thegaragistes movement began with small-scale production of highly sought after Merlot-based wines. In thesandy, clay-limestone-based soils ofSaint-Émilion, Merlot accounts for around 60% of the blend and is usually blended with Cabernet Franc. In limestone, Merlot tends to develop more perfume notes while in sandy soils the wines are generally softer than Merlot grown in clay dominant soils.[6] Merlot can also be found in significant quantities inProvence,Loire Valley,Savoie,Ardèche,Charente,Corrèze,Drôme,Isère andVienne.[6]

In Italy, there were 25,614 hectares (63,290 acres) of the grape planted in 2000 with more than two-thirds of Italian Merlot being used inIndicazione geografica tipica (IGT) blends (such as the so-called "Super Tuscans") versus being used in classifiedDenominazione di origine controllata (DOC) orDenominazione di Origine Controllata e Garantita (DOCG) wines.[1] A large portion of Merlot is planted in theFriuli wine region where it is made as a varietal or sometimes blended with Cabernet Sauvignon or Cabernet Franc. In other parts of Italy, such as theMaremma coast inTuscany, it is often blended withSangiovese to give the wine a similar softening effect as the Bordeaux blends.[10]
Italian Merlots are often characterized by their light bodies and herbal notes.[8] Merlot's low acidity serves as a balance for the higher acidity in many Italian wine grapes with the grape often being used in blends in theVeneto,Alto Adige, andUmbria regions.[6]Global warming is potentiallyhaving an influence on Italian Merlot as more cooler-climate regions in northern Italy are being able to ripen the grape successfully while other regions already planted are encountering issues with over-ripeness.[1]
According toMaster of WineJancis Robinson, some of the higher quality Italian Merlots are often from vineyards planted withcuttings sourced from France. Robinson describes the style of Friuli Merlots from regarded estates as having potentially a "Pomerol-quality" to them while Merlots from the warm plains of the Veneto can often be over-ripe with high yields giving them a "sweet and sour" quality. Robinson notes that the Merlots from Trentino-Alto-Adige can fall somewhere between those of Friuli and the Veneto.[1] TheStrada del Merlot is a popular tourist route through Italian Merlot regions along theIsonzo river.[7]
In the hotcontinental climate of many of Spain's major wine regions, Merlot is less valued than it is in the dampmaritime climate of Bordeaux or the warmMediterranean climate of the Tuscan coast.[1] But as the popularity ofinternational varieties continue to grow on the world wine market, Spanish wine producers have been experimenting with the variety with even winemakers inRioja petitioning authorities to allow Merlot to be a permitted grape to be blended withTempranillo in the red wines of the region.[6]
In 2008, there were 13,325 hectares (32,930 acres) of Merlot, a significant increase from the 8,700 hectares (21,000 acres) that were being cultivated in the country only four years earlier.[1] In 2015, this had dropped slightly to 13,044 hectares (32,230 acres), making Merlot the eighth most planted red grape variety in Spain. The largest concentration of the grape is in the Mediterranean climate ofCatalonia and the continental climate ofCastilla–La Mancha, with significant plantings also inNavarra andAragon. InCosters del Segre, the grape is often used in Bordeaux-style blends while inAragon,Navarra, andCastilla-La Mancha it is sometimes blended with Tempranillo and other local Spanish wine grape varieties.
InSwitzerland, Merlot accounts for nearly 85% of the wine production inTicino where it is often made in a pale "white Merlot" style.[6] In 2009, there were 1,028 hectares (2,540 acres) plantings of Swiss Merlot.[1]
Plantings of Merlot have increased in recent years in theAustrian wine region ofBurgenland where vineyards previously growingWelschriesling are being uprooted to make room for more plantings.[6] The grape still lags behind its parent variety, Cabernet Franc, with 112 hectares (280 acres) in cultivation in 2008. Outside of Burgenland, nearly half of all Austrian Merlot plantings are found inLower Austria.[1]
In theEastern European countries ofBulgaria,Moldova,Croatia, andRomania, Merlot is often produced as a full bodied wine that can be very similar to Cabernet Sauvignon.[10] In Bulgaria, plantings of Merlot lag slightly behind Cabernet Sauvignon with 15,202 hectares (37,560 acres) in 2009 while Croatia had 1,105 hectares (2,730 acres). In theCzech Republic, most of the country's 87 hectares (210 acres) were found inMoravia while Moldova had 8,123 hectares (20,070 acres) in 2009.[1]
InSlovenia, Merlot was the most widely planted grape variety of any color in theVipava Valley in theSlovene Littoral and the second most widely planted variety in theGorizia Hills located across the Italian border from Friuli. In the Slovene Littoral, collectively, Merlot accounts for around 15% of total vineyard plantings with 1,019 hectares (2,520 acres) of Merlot in cultivation across Slovenia in 2009.[1]
InHungary, Merlot complementsKékfrankos,Kékoportó, andKadarka as a component inBull's Blood. It is also made into varietal wine known asEgri Médoc Noir which is noted for its balanced acid levels and sweet taste.[7] In 2009, there were 1,791 hectares (4,430 acres) of Merlot planted across Hungary. Most of these hectares can be found in the wine regions ofSzekszárd andVillány on the warmPannonian Basin with significant plantings also found inKunság,Eger, andBalaton.[1]
In Romania, Merlot is the most widely exported red wine grape variety with 10,782 hectares (26,640 acres) in cultivation in 2008. Most of these plantings are found along theBlack Sea inDobruja, further inland in theMuntenia region ofDealu Mare and in the western Romanian wine region ofDrăgășani. Here the grape is often made a varietal but is sometimes blended with other international varieties such as Cabernet Sauvignon and with local grape varieties such asFetească neagră.[1]
In 2009,Ukraine had 2,820 hectares (7,000 acres) of Merlot in cultivation.
InGreece, Merlot is one of the top six grape varieties planted in the eastern wine regions ofMacedonia (86 hectares (210 acres))andWestern Thrace (243 hectares (600 acres)). In central Greece, there were 74 hectares (180 acres) of Merlot in cultivation as of 2012.[1]
Merlot is grown across the United States—as of 2015, it is the fourth most planted wine grape[13]—withCalifornia andWashington growing the most. Other regions producing significant quantities of Merlot includeNew York State with 365 hectares (900 acres) in 2006 with most of it in the maritime climate of theLong Island AVA and multiple regions inOhio. InTexas, Merlot is the second most widely planted red wine grape after Cabernet Sauvignon with 117 hectares (290 acres). In Virginia, the grape was the most widely planted red variety with 136 hectares (340 acres) in 2010, most of it in theMonticello AVA andShenandoah Valley AVA, whileOregon had 206 hectares (510 acres) in 2008 with most planted in theRogue Valley AVA.[1][8]
The style of Merlot in California can vary with the grape being found all across the state in both warmer and cooler climate regions. While regional examples of California Merlot exist from places like Napa Valley and Sonoma, many bottles are labeled simply asCalifornia Merlot.
In the earlyhistory of California wine, Merlot was used primarily as a 100%varietal wine until winemakerWarren Winiarski encouraged taking the grape back to its blending roots with Bordeaux style blends.[14] Others saw its potential as a stand-alone labeled varietal: The first wineries to market Merlot as a varietal in the post WWII period were Louis M. Martini winery, which made a non-vintage dated Merlot, a blend of the 1968 and 1970 vintages, andSterling Vineyards, which issued the first Merlot with a vintage, 1969[15] —Sterling's winemaker,Ric Forman, was an early advocate of Merlot as a varietal bottling.[16] Following the "Merlot wine craze" of the 1990s, sparked by60 MinutesFrench Paradox report, sales of Merlot spiked, with the grape plantings of over 20,640 hectares (51,000 acres) in 2004. A study published inWine and Vines magazine indicated that the 2004 movieSideways, where the lead character is aPinot noir fan who expresses his disdain of Merlot, caused a decline in Merlot sales in the US after its release (and an even larger spike of interest in Pinot noir).[17] By 2010, plantings of California Merlot had dropped slightly to 18,924 hectares (46,760 acres).[1][18][19] Following that dip, Merlot plantings rebounded, totaling approximately 39,000 acres in 2020.[20]
In California, Merlot can range from very fruity simple wines (sometimes referred to by critics as a "redChardonnay") to more serious,barrel aged examples. It can also be used as a primary component inMeritage blends.[10]
In the 1980s, Merlot helped put the Washington wine industry on the world's wine map. Prior to this period there was a general perception that the climate of Washington State was too cold to produce red wine varietals. Merlots fromLeonetti Cellar,Andrew Will,Columbia Crest, andChateau Ste. Michelle demonstrated that areas of theEastern Washington were warm enough for red wine production.[21] Today it is the second most widely grown red wine grape in the state (after Cabernet Sauvignon), following many years of being the most widely planted variety, and accounts for nearly one fifth of the state's entire production. In 2011, there were 3,334 hectares (8,240 acres) of Washington Merlot in cultivation.[1]
Washington Merlots from the Columbia Valley are often noted for their deep color.
InCanada, Merlot can be found across the country from theShort Hills Bench of theNiagara PeninsulaOntario, where there were 498 hectares (1,230 acres) of the grape in 2008, toBritish Columbia, where the grape is the most widely planted wine grape variety of either color at 641 hectares (1,580 acres). Here Merlot accounts for almost a third of all red wine grape plantings and is used for both varietal and Bordeaux-style blends.[1]
InMexico, Merlot is cultivated primarily in theValle de Guadalupe ofBaja California, the country's main wine-producing area. Plantings have increased substantially since the 1980s, and cultivation has spread into the nearby areas ofOjos Negros andSanto Tomás.[10] The grape can also be found in the north eastern Mexican wine region ofCoahuila, across the border from Texas.[1]
InChile, Merlot thrives in theApalta region ofColchagua Province. It is also grown in significant quantities inCuricó,Casablanca, and theMaipo Valley. Until the early 1990s, the Chilean wine industry mistakenly sold a large quantity of wine made from the Carménère grape as Merlot. Following the discovery that many Chilean vineyards thought to be planted withSauvignon blanc were actuallySauvignonasse, the owners of the Chilean wineryDomaine Paul Bruno (who previously worked withChâteau Margaux andChâteau Cos d'Estournel) invitedampelographers to comb through their vineyards to make sure that their wines were properly identified. Genetic studies discovered that much of what had been grown as Merlot was actuallyCarménère, an old French variety that had gone largely extinct in France due to its poor resistance tophylloxera. While the vines, leaves, and grapes look very similar, both grapes produce wines with distinct characteristics—Carménère being more strongly flavored with green pepper notes and Merlot having softer fruit with chocolate notes.[10]
Today, "true" Merlot is the third most widely planted grape variety in Chile after Cabernet Sauvignon andListán Prieto with 13,280 hectares (32,800 acres) in 2009. Most of these planting are in theCentral Valley, with Colchagua leading the way with 3,359 hectares (8,300 acres), followed byMaule Valley with 3,019 hectares (7,460 acres) and Curicó with 2,911 hectares (7,190 acres).[1]
InUruguay, Merlot is often blended withTannat and is the 2nd most widely planted red grape variety, representing around 10% of total vineyard plantings. More widely planted than Cabernet Sauvignon, there were 853 hectares (2,110 acres) of the grape in cultivation in 2009.Brazil is home to 1,089 hectares (2,690 acres) of Merlot (as of 2007) with most of them in theRio Grande do Sul region that is across the border with Uruguay. Other South American wine regions growing Merlot includeBolivia with 30 hectares (74 acres) as of 2012 andPeru.[1]
InArgentina, Merlot plantings have been increasing in theMendoza region with the grape showing an affinity to theTupungato region of theUco Valley. Argentine Merlots grown in the higher elevations of Tunpungato have shown a balance of ripe fruit, tannic structure, and acidity.[10] The grape is not as widely planted here due to the natural fruity and fleshiness of the popularMalbec andDouce noir/Bonarda grapes that often don't need to be "mellowed" by Merlot as Cabernet Sauvignon and Cabernet Franc may benefit from. In 2008, there were 7,142 hectares (17,650 acres) of Merlot growing in Argentina, most of it in the Mendoza region and in theSan Juan Province.[1]
InNew Zealand, plantings of Merlot have increased in theHawke's Bay region, particularly inGimblett Gravels where the grape has shown the ability to produce Bordeaux-style wine.[8] The grape has been growing in favor among New Zealand producers due to its ability to ripen better, with less green flavors, than Cabernet Sauvignon. Other regions with significant plantings includeAuckland,Marlborough, andMartinborough.[6] In 2008, Merlot was the second most widely red grape variety (after Pinot noir) in New Zealand and accounted for nearly 5% of all the country's plantings with 1,363 hectares (3,370 acres) in cultivation.[1]
InAustralia, some vineyards labeled as "Merlot" were discovered to actually be Cabernet Franc. Merlot vines can also be found growing in theBarossa Valley,McLaren Vale, andWrattonbully inSouth Australia.[6] In 2008, it was the third most widely planted red grape variety afterSyrah and Cabernet Sauvignon with 10,537 hectares (26,040 acres). As in California, the global "Merlot craze" spurred an increase of plantings, most of it in the warm,irrigated regions ofMurray Darling,Riverina, andRiverland, where the grape variety could be mass-produced. Recent plantings, such as those in theMargaret River area ofWestern Australia have been focusing on making more Bordeaux-style blends.[1]
InSouth Africa, plantings of Merlot have focused on cooler sites within thePaarl andStellenbosch regions.[6] Here the grape is the third most widely planted red grape variety, accounting for nearly 15% of all red wine grape plantings, with 6,614 hectares (16,340 acres) of Merlot in cultivation in 2008. The majority of these plantings are found in the Stellenbosch region with 2,105 hectares (5,200 acres) and Paarl with 1,289 hectares (3,190 acres). According to wine expert Jancis Robinson, South African Merlot tend to be made as a varietal in a "chocolately, glossy California style".[1]
In Asia, Merlot is planted in emerging wine regions inIndia. It can also be found in Japan with 816 hectares (2,020 acres) in 2009 and in China with 3,204 hectares (7,920 acres).[1]
White Merlot is made the same way asWhite Zinfandel. The grapes are crushed, and after very brief skin contact, the resulting pink juice is run off themust and is then fermented. It normally has a hint of raspberry. White Merlot was reputedly first marketed in the late 1990s. In Switzerland, a type of White Merlot is made in the Ticino region but has been considered more a rosé.[6]
White Merlot should not be confused with the grape varietyMerlot blanc, which is a cross between Merlot andFolle blanche that was discovered in 1891,[1][22] nor should it be confused with the white mutant variety of the Merlot grape.
Infood and wine pairings, the diversity of Merlot can lend itself to a wide array of matching options. Cabernet-like Merlots pair well with many of the same things that Cabernet Sauvignon would pair well with, such as grilled and charred meats. Softer, fruitier Merlots (particularly those with higher acidity from cooler climate regions like Washington State and Northeastern Italy) share many of the same food-pairing affinities withPinot noir and go well with dishes likesalmon, mushroom-based dishes, and greens likechard andradicchio. Light-bodied Merlots can go well withshellfish like prawns or scallops, especially if wrapped in a protein-rich food such asbacon orprosciutto. Merlot tends not to go well with strong andblue-veined cheeses that can overwhelm the fruit flavors of the wine. Thecapsaicins of spicy foods can accentuate the perception of alcohol in Merlot and make it taste more tannic and bitter.[8]
Over the years, Merlot has been known under many synonyms across the globe, including Bégney, Bidal, Bidalhe, Bigney, Bigney rouge, Bini, Bini Ruzh, Bioney, Bordeleza belcha, Crabutet, Crabutet noir, Crabutet noir merlau, Hebigney, Higney, Higney rouge, Langon, Lecchumskij, Médoc noir, Merlau, Merlaut, Merlaut noir, Merle, Merle Petite, Merleau, Merlô, Merlot noir, Merlot black, Merlot blauer, Merlot crni, Merlot nero, Merlott, Merlou, Odzalesi, Odzhaleshi, Odzhaleshi Legkhumskii, Petit Merle, Picard, Pikard, Plan medre, Planet Medok, Plant du Médoc, Plant Médoc, Saint-Macaire, Same de la Canan, Same dou Flaube, Sème de la Canau, Sème Dou Flube, Semilhon rouge, Semilhoum rouge, Semilhoun rouge, Sémillon rouge, Sud des Graves, Vidal, Vini Ticinesi, Vitrai, and Vitraille.[23]
