Answer the following question: Information:  - Carignan (also known as Mazuelo, Bovale Grande, Cariñena, Samsó, and Carignane) is a red Spanish/French wine grape variety that is widely planted throughout the western Mediterranean and around the globe. Along with Aramon, it was once 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.  - A Bordeaux wine is any wine produced in the Bordeaux region of France, centred on the city of Bordeaux 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. Average vintages produce over 700 million bottles of Bordeaux wine, ranging from large quantities of everyday table wine, to some of the most expensive and prestigious wines in the world. The vast majority of wine produced in Bordeaux is red (called "claret" in Britain), with sweet white wines (most notably Sauternes), dry whites, and (in much smaller quantities) rosé and sparkling wines (Crémant de Bordeaux) collectively making up the remainder. Bordeaux wine is made by more than 8,500 producers or "châteaux". There are 54 appellations of Bordeaux wine.  - French wine is produced all throughout France, in quantities between 50 and 60 million hectolitres per year, or 78 billion bottles. France is one of the largest wine producers in the world. French wine traces its history to the 6th century BC, with many of France's regions dating their wine-making history to Roman times. The wines produced range from expensive high-end wines sold internationally to more modest wines usually only seen within France such as the Margnat wines were during the post war period.  - Vitis (grapevines) is a genus of 79 accepted species of vining plants in the flowering plant family Vitaceae. The genus is made up of species predominantly from the Northern hemisphere. It is economically important as the source of grapes, both for direct consumption of the fruit and for fermentation to produce wine. The study and cultivation of grapevines is called viticulture.  - A grape is a fruit, botanically a berry, of the deciduous woody vines of the flowering plant genus "Vitis".  - In botany, a fruit is the seed-bearing structure in flowering plants (also known as angiosperms) formed from the ovary after flowering.  - Ruby Cabernet is a red Olmo grape variety that is a cross between Cabernet Sauvignon and Carignan , it can produce wines with good colour and a pleasant cherry flavour , but is mostly blended into bulk wines . The purpose for the creation of the crossing of the grape varieties utilized to produce Ruby Cabernet was to obtain the superior quality of a Cabernet wine , and the resistance to heat of the Carignan combined in an inexpensive table wine . Even though the wine made from these grapes does not possess the distinctive flavor and the overall structure of other types of Cabernet wines , it does carry their fruitful essence . The grape for this type of red wine was developed for California 's hot climate , specially for regions such as the San Joaquin and the Napa Valleys . Ruby Cabernet has improved the quality of the bulk wines produced in these areas thanks to its natural , special acidity .  - Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, and the Mediterranean Sea to the south. To the east and southeast, Europe is generally considered as separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways of the Turkish Straits. Yet the non-oceanic borders of Europea concept dating back to classical antiquityare arbitrary. The primarily physiographic term "continent" as applied to Europe also incorporates cultural and political elements whose discontinuities are not always reflected by the continent's current overland boundaries.  - France, officially the French Republic, is a country with territory in western Europe and several overseas regions and territories. The European, or metropolitan, area of France extends from the Mediterranean Sea to the English Channel and the North Sea, and from the Rhine to the Atlantic Ocean. Overseas France include French Guiana on the South American continent and several island territories in the Atlantic, Pacific and Indian oceans. France spans and had a total population of almost 67 million people as of January 2017. It is a unitary semi-presidential republic with the capital in Paris, the country's largest city and main cultural and commercial centre. Other major urban centres include Marseille, Lyon, Lille, Nice, Toulouse and Bordeaux.  - The Beqaa Valley (',  ), also transliterated as Bekaa, Biqâ and Becaa and known in Classical antiquity as Coele-Syria, is a fertile valley in eastern Lebanon. It is Lebanon's most important farming region. Industry also flourishes in Beqaa, especially that related to agriculture.  - A genus ( genera) is a taxonomic rank used in the biological classification of living and fossil organisms in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.  - Deciduous means "falling off at maturity" " or "tending to fall off", and it is typically used in order to refer to trees or shrubs that lose their leaves seasonally (most commonly during autumn) and to the shedding of other plant structures such as petals after flowering or fruit when ripe. In a more general sense, "deciduous" means "the dropping of a part that is no longer needed" or "falling away after its purpose is finished". In plants it is the result of natural processes. "Deciduous" has a similar meaning when referring to animal parts, such as deciduous antlers in deer or deciduous teeth, also known as baby teeth, in some mammals (including humans).  - The wine lake refers to the continuing supply surplus of wine produced in the European Union. A major contributor to that glut is the Languedoc-Roussillon, which produces over one-third of the grapes grown in France. In 2007 it was reported that for the previous several vintages, European countries had been producing 1.7 billion more bottles of wine than they sell. Hundreds of millions of bottles of wine are turned into industrial alcohol every year, a practice that is sometimes described as "emergency distillation".  - Wine (from Latin "vinum") is an alcoholic beverage made from fermented grapes. These grapes are generally "Vitis vinifera," or a hybrid with "Vitis labrusca" or "Vitis rupestris". Grapes are fermented without the addition of sugars, acids, enzymes, water, or other nutrients. Yeast consumes the sugar in the grapes and converts it to ethanol and carbon dioxide. Different varieties of grapes and strains of yeasts produce different styles of wine. These variations result from the complex interactions between the biochemical development of the grape, the reactions involved in fermentation, the terroir, and the production process. Many countries enact legal appellations intended to define styles and qualities of wine. These typically restrict the geographical origin and permitted varieties of grapes, as well as other aspects of wine production.  - Cabernet Sauvignon is one of the world's most widely recognized red wine grape varieties. It is grown in nearly every major wine producing country among a diverse spectrum of climates from Canada's Okanagan Valley to Lebanon's Beqaa Valley. Cabernet Sauvignon became internationally recognized through its prominence in Bordeaux wines where it is often blended with Merlot and Cabernet Franc. From France, the grape spread across Europe and to the New World where it found new homes in places like California's Santa Cruz Mountains, Napa Valley, New Zealand's Hawkes Bay, Australia's Margaret River and Coonawarra regions, and Chile's Maipo Valley and Colchagua. For most of the 20th century, it was the world's most widely planted premium red wine grape until it was surpassed by Merlot in the 1990s.  - The flowering plants (angiosperms), also known as Angiospermae or Magnoliophyta, are the most diverse group of land plants, with 416 families, approx. 13,164 known genera and a total of c. 295,383 known species. Like gymnosperms, angiosperms are seed-producing plants; they are distinguished from gymnosperms by characteristics including flowers, endosperm within the seeds, and the production of fruits that contain the seeds. Etymologically, angiosperm means a plant that produces seeds within an enclosure, in other words, a fruiting plant. The term "angiosperm" comes from the Greek composite word ("angeion", "case" or "casing", and "sperma", "seed") meaning "enclosed seeds", after the enclosed condition of the seeds.  - A vine (Latin "vnea" "grapevine", "vineyard", from "vnum" "wine") in the narrowest sense is the grapevine ("Vitis"), but more generally it can refer to any plant with a growth habit of trailing or (that is, climbing) stems or runners. The word also can refer to such stems or runners themselves, for instance when used in wicker work.  - "Jug wine" is a term in the United States for inexpensive table wine (or "bulk wine") typically bottled in a glass jug.   - 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.  - Cabernet Franc is one of the major black grape varieties worldwide. It is principally grown for blending with Cabernet Sauvignon and Merlot in the Bordeaux style, but can also be vinified alone, as in the Loire's Chinon. In addition to being used in blends and produced as a varietal in Canada and the United States, it is made into ice wine in those regions.    What is the relationship between 'ruby cabernet' and 'varietal'?
