Question: Which red wine variety made in Nistreana is increasingly celebrated as an Argentine varietal wine?

full_context: Document 1: 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.
Document 2: Petit Manseng: Petit Manseng (sometimes translated: Small Manseng, rarely "Little Manseng") is a white wine grape variety that is grown primarily in South West France. It produces the highest quality wine of any grape in the Manseng family. The name is derived from its small, thick skin berries. Coupled with the small yields of the grapevine, most Petit Manseng farmers produce around 15 hl of wine per hectare. The grape is often left on the vine till December to produce a late harvest dessert wine. The grape is grown primarily in Gascony, Jurançon and Pacherenc du Vic-Bilh but has recently drawn interest in New World wine regions like California, North Georgia, Virginia, Ohio, and Australia. The reason is that it is expected to follow Viognier's path to popularity among white wine drinkers. It was already present in Uruguay, when Basque settlers brought "Manseng" and Tannat vines with them to their new home. Despite being easily recognizable as a white grape while true Manseng is a black grape, wine that is Petit Manseng is still normally labeled as just "Manseng". The grape is often left on the vine to produce a late harvest wine made from its nearly raisin like grapes.
Document 3: Wachau wine: Wachau is one of Austria's most established and notable wine regions, specializing in dry wines made from Riesling and Grüner Veltliner. Located in Lower Austria along the Danube, west of Vienna and Krems an der Donau, it is one of the westernmost wine producing regions in Austria with only a few scattered plantings in Tyrol being further west. While most of Austria follows a wine classification systems based on ripeness and harvest must weight that parallels the German wine classification system, Wachau wines have a unique classification system. The three classification levels for Wachau wine include "Steinfeder" for wines up to 11.5% alcohol level, "Federspiel" for wines between 11.5–12.5% and "Smaragd" that must have a minimum of 12.5% alcohol level. Despite its renown, the Wachau is a small wine region that usually accounts for only around 3% of Austria's wine production.
Document 4: Hunter Valley wine: The Hunter Valley is one of Australia's best known wine regions. Located in the state of New South Wales, the region has played a pivotal role in the history of Australian wine as one of the first wine regions planted in the early 19th century. Hunter Valley Semillon is widely considered the iconic wine of the region but the Hunter produces wine from a variety of grapes including Shiraz, Chardonnay, Cabernet Sauvignon and Verdelho.
Document 5: 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.
Document 6: New South Wales wine: New South Wales wine is Australian wine produced in New South Wales, Australia. New South Wales is Australia's most populous state and its wine consumption far outpaces the region's wine production. The Hunter Valley, located 130 km north of Sydney, is the most well-known wine region but the majority of the state's production takes place in the Big Rivers zone-Perricoota, Riverina and along the Darling and Murray Rivers. The wines produced from the Big Rivers zone are largely used in box wine and mass-produced wine brands such as Yellow Tail. A large variety of grapes are grown in New South Wales, including Cabernet Sauvignon, Chardonnay, Shiraz and Sémillon.
Document 7: 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.
Document 8: 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.
Document 9: 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.
Document 10: Black Spanish (grape): Black Spanish is now known to be a seedling of an American hybrid grape resulting from a cross of the American "Vitis aestivalis" species of grape with an unknown "Vitis vinifera" pollen donor. This hybridization is not known to have been purposeful, and may have occurred naturally, as was the case with many of the early American grape cultivars. Recently, it was revealed from the microsatellite DNA (a.k.a. Simple Sequence Repeats or SSRs) analyses conducted on various 'Jacquez cultivars' by Dr Jerry Rodrigues that at least two of the European accessions (grapevine collections) which are presently curated in Europe were originally derived from the oldest known Jacquez cultivar (the Madeira Jacquez). The original American hybrid grape parent had found its way to the Madeira Islands early in the 18th century (where it was called Jaquez or Jacquet) and thence to France. Lenoir is another such seedling similar to Black Spanish which was propagated by Herbemont. Many other historical names appeared on the scene throughout the early history of these Jacquez seedlings such as Jack, Blue French, Ohio, and El Paso, among others. For example, Herbemont tells us that he received Lenoir seeds from a man named Lenoir who cultivated it near Stateburg SC, in the vicinity of the Santee River sometime in the 18th Century. Lenoir made its way to Texas early, where it even took on the names El Paso and Black Spanish. From its wild South Carolina parent, Lenoir (and also Black Spanish) carries natural resistance to the Phylloxera pest, as well as to the deadly Pierce's Disease, which is a common threat to "Vitis vinifera" vineyards in warm winter areas of the United States. Lenoir was also one of the American vines which the grape breeder Thomas Volney Munson experimented with in the late 19th Century in Denison, Texas. Prior to its use by Munson, Lenoir was grown and used in wine by Nicholas Herbemont of Columbia, South Carolina in the 1830s, though to a lesser extent than the similar, lighter-skinned variety "Warren" ("Brown French") which become known as Herbemont because of his promotion of that variety. Lenoir was introduced to Europe in the mid-19th Century, where French vintners were intrigued by its similarity to European "Vitis vinifera" winegrapes, and gave it the names Jacquez and Jacquet. It became an important direct producing grape in Europe during the phylloxera crisis, and later was used to some extent as a rootstock to protect the classic vinifera grapes from phylloxera. Ulysses P. Hedrick's famous "Grapes of New York" in 1908 provides the seminal discussion of Lenoir and many of the early North American grapes.
Document 11: Muscat of Alexandria: Muscat of Alexandria is a white wine grape that is a member of the Muscat family of "Vitis vinifera". It is considered an "ancient vine", and wine experts believe it is one of the oldest genetically unmodified vines still in existence. While today it is mostly cultivated as a table grape or for raisin production, it is still an important grape in the Australian and South African wine industry. It is also cultivated very heavily on the islands of Samos, and Lemnos in the North Eastern Aegean region of Greece, and reputedly Cleopatra drank muscat wine from there. It is also thought to rival the French "Beaume de Venise" in its most refined form. In Italy wine is made from the grape on the island of Pantelleria, and in Spain, the grape is used for wine around Málaga, Alicante, Valencia, and the Canary Islands. The grape originated in North Africa, and the name is probably derived from its association with Ancient Egyptians who used the grape for wine making. It is also a table grape used for eating and raisins.
Document 12: Sena wine: Seña wine was established as a collaborative venture in Chile between Viña Errázuriz and Robert Mondavi . Since 2005 Seña is owned 100% by the Chadwick family, proprietors of Errázuriz, and is the personal project of Eduardo Chadwick. Eduardo's ambition is to create a Chilean icon wine, one which fully expresses the terroir (wine identity linked to local soil, aspect and climate) of the Aconcagua Valley north of Santiago. The inaugural vintage of Seña, which is Spanish for distinguishing mark or personal signature, was that of 1995. The wine is made from a blend of six of the classic red grape varietals: Cabernet Sauvignon, Merlot, Carmenère, Cabernet Franc, Petit Verdot and Malbec. The grapes for Seña are sourced from Seña Hillside vineyards within the Aconcagua Valley, in which vines are grown according to bio-dynamic principles. The wine is currently produced at Errázuriz's Don Maximiano Estate winery in the Aconcagua Valley.
Document 13: 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.
Document 14: 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.
Document 15: Vinagro: “Goygol Wine Plant” is an Azerbaijani winery with history of 150 years. Established in 1860, the Plant was built by German refugees – Shwabs, who founded Yelenendorf Settlement by settling down an area in Elizabethpol province, in Goygol Region. In 1862 there was established «Brothers Forrer» Joint-Stock company that was directed by sons Ch. Forrer – Gottlob, Friedrich, Heinrich and Christofor. At the same time there was established «Trade house of Brothers Hummel» joint-stock company that was directed by Ch. Hummel sons – Jacob, Albert, George and Gottlieb. Board of the both families was located in Elenendorf, offices and representation were in Ganja, Tbilisi, Baku, St. Petersburg, Moscow, Kiev, Odessa, Tomsk, Batumi. The Yelenendorf Wines manufactured by the winery distilleries established by Christopher Forer and Christian Gummel were being exported to Germany and Netherland. On August 8, 1922 there was established cooperative «Concordia» in base of wine factory that became the largest producer of wine, cognac and vodka in Transcaucasus. The company was producing "Kagor", "Old Port", "White table wine", "Red table wine", "Xeres wines", "Garangush", "Extra" cognacs, liqueurs and champagnes. For example during 1924-1925 branches of cooperative «Concordia» registered 1350397 buckets of wine.
