Which red wine variety made in Nistreana is increasingly celebrated as an Argentine varietal wine?
Malbec
Malbec
Malbec (] ) is a purple grape variety used in making red wine.
 The grapes tend to have an inky dark color and robust tannins, and are known as one of the six grapes allowed in the blend of red Bordeaux wine.
 The French plantations of Malbec are now found primarily in Cahors in South West France.
 It is increasingly celebrated as an Argentine varietal wine and is being grown around the world.
Nistreana (wine)
Purcari Wine Region (also called "Nistreana") is a Moldovan wine region.
 The southeastern Purcari zone stretches along the Western Dniester coast.
 Here is the Purcari winemaking center is situated, made famous by its red wines: Roşu de Purcari and Negru de Purcari.
 The climatic conditions are favorable to the cultivation of red grape varieties: Chardonnay, Sauvignon blanc, Cabernet Sauvignon, Merlot, Pinot noir, Malbec, Rara Neagră and Saperavi, which serve as the basis for the production of aged wines.
 At the end of the 19th century the Purcari wines were supplied to the English royal court.
Krasnostop Zolotovsky
Krasnostop Zolotovsky is an indigenous Russian grape variety that is regarded as the local grape with the best potential for red wine production.
 The name 'Krasnostop' is derived from the Russian words krasniy and stopka, meaning red and shot glass respectively, that describe the appearance of its stems.
 It gives wines that are typically rich in tannins, alcohol and acidity, with flavors reminiscent of dark plums, redcurrant and green pepper.
 Notable producers include Vedernikov Winery and Domaines Burnier, both of which produce a varietal wine from this rare grape. Petit Verdot
Petit Verdot is a variety of red wine grape, principally used in classic Bordeaux blends.
 It ripens much later than the other varieties in Bordeaux, often too late, so it fell out of favour in its home region.
 When it does ripen it adds tannin, colour and flavour, in small amounts, to the blend.
 Petit verdot has attracted attention among winemakers in the New World, where it ripens more reliably and has been made into single varietal wine.
 It is also useful in 'stiffening' the mid palate of Cabernet Sauvignon blends. Sciacarello
Sciacarello (or "sciaccarello") is a red Italian wine grape variety that is grown primarily in Corsica.
 It is most noted for the wines that come from Ajaccio which tend to be highly perfumed.
 It is also associated with wines from Calvi, and in the Sartène region around Proprioano.
 The grape is normally blended and rarely made into a varietal wine.
 Sciacarello is believed to be a parent vine of the Ligurian-Tuscan wine grape, pollera nera.
 Di Vecchi Staraz, Bandinelli, Boselli, This, Boursiquot, Laucou, Lacombe, and Varès (2007) showed that Sciaccarello (or Sciaccarellu as it is known in Corsica) and another Corsican variety Malvasia Montanaccio as well as Tuscan varieties Biancone, Caloria, Colombana Nera, and Pollera Nera have genetic ties to Mammolo. Tinta Miuda
Tinta Miuda is a Portuguese red wine grape that is grown primarily in the Oeste and Ribatejo regions.
 The grape is often used in the production of blended bulk and table wines but can also be used to produce varietal wine. Zierfandler
Zierfandler is a grape variety used to make white wine in the Thermenregion of Austria.
 It is also known as Spätrot ("late red") because it turns red just before harvest time.
 It is traditionally blended with Rotgipfler but is increasingly being sold as a single varietal wine.
 Zierfandler wines are typically elegant and quite sweet, but with lots of balancing acidity and a nutty bouquet of pistachios and almonds.
 They are capable of ageing well. Varietal
A varietal wine is a wine made primarily from a single named grape variety, and which typically displays the name of that variety on the wine label.
 Examples of grape varieties commonly used in varietal wines are Cabernet Sauvignon, Chardonnay and Merlot.
 Wines that display the name of two or more varieties on their label, such as a Chardonnay-Viognier, are blends and not varietal wines.
 The term is frequently misused in place of vine variety; the term variety refers to the vine or grape while varietal refers to the wine produced by a variety. Vino Nobile di Montepulciano
Vino Nobile di Montepulciano is a red wine with a Denominazione di Origine Controllata e Garantita status produced in the vineyards surrounding the town of Montepulciano, Italy.
 The wine is made primarily from the Sangiovese grape varietal (known locally as "Prugnolo gentile") (minimum 70%), blended with Canaiolo Nero (10%–20%) and small amounts of other local varieties such as Mammolo.
 The wine is aged for 2 years (at least 1 year in oak barrels); three years if it is a riserva.
 The wine should not be confused with Montepulciano d'Abruzzo, a red wine made from the Montepulciano grape in the Abruzzo region of east-central Italy. Ruché
Ruché (pronounced in English , ] ) is a red Italian wine grape variety from the Piedmont region.
 It is largely used in making Ruché di Castagnole Monferrato, a small production red varietal wine which was granted "Denominazione di Origine Controllata" (DOC) status by presidential decree on October 22, 1987, and was granted the more prestigious "Denominazione di Origine Controllata e Garantita" (DOCG) status in 2010.
 The current DOC recognized area of production for the wine, covers only about 100 acres (40 hectares) of vines around the villages of Castagnole Monferrato, Refrancore, Grana, Montemagno, Viarigi, Scurzolengo and Portacomaro.
 Ruché di Castagnole Monferrato is, therefore, one of the lowest production varietal wines in Italy.
 The grape is also grown to some extent in the neighboring province of Alessandria.
