Cabernet Sauvignon in oak will make you a red wine lover today.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 Napa Valley, Australia's Coonawarra region and Chile's Maipo Valley. 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. Despite its prominence in the industry, the grape is a relatively new variety, the product of a chance crossing between Cabernet franc and Sauvignon blanc during the 17th century in southwestern France. Its popularity is often attributed to its ease of cultivation - the grapes have thick skins and the vines are hardy and resistant to rot and frost - and to its consistent presentation of structure and flavors which express the typical character ("typicity") of the variety. Familiarity and ease of pronunciation have helped to sell Cabernet Sauvignon wines to consumers, even when from unfamiliar wine regions. Its widespread popularity has also contributed to criticism of the grape as a "colonizer" that takes over wine regions at the expense of native grape varieties.
For many years, the origin of Cabernet Sauvignon was not clearly understood and many myths and conjectures surrounded it. The word "Sauvignon" is believed to be derived from the French sauvage meaning "wild" and to refer to the grape being a wild Vitis vinifera vine native to France. Until recently the grape was rumoured to have ancient origins, perhaps even being the Biturica grape used to make ancient Roman wine and referenced by Pliny the Elder. This belief was widely held in the 18th century, when the grape was also known as Petite Vidure or Bidure, apparently a corruption of Biturica. There was also belief that Vidure was a reference to the hard wood (French vigne dure) of the vine, with a possible relationship to Carménère which was once known as Grand Vidure. Other theories were that the grapevine originated in the Rioja region of Spain. While the period when the name Cabernet Sauvignon became more prevalent over Petite Vidure is not certain, records indicate that the grape was a popular Bordeaux planting in the 18th century Médoc region. The first estates known to have actively grown the variety (and the likely source of Cabernet vines for other estates) were Château Mouton and Château d'Armailhac in the Pauillac. The grape's true origins were discovered in the late 1990s with the use of DNA typing at the UC Davis Department of Viticulture and Enology, by a team led by Dr. Carole Meredith. The DNA evidence determined that Cabernet Sauvignon was the offspring of Cabernet franc and Sauvignon blanc and was most likely a chance crossing that occurred in the 17th century. Prior to this discovery, this origin had been suspected from the similarity of the grapes' names and the fact that Cabernet Sauvignon shares similar aromas with both grapes—such as the black currant and pencil box aromas of Cabernet franc and the grassiness of Sauvignon blanc.
Tasting Notes There are a couple of noted Cabernet Sauvignon flavors that are intimately tied to viticultural and climate influences. The most widely recognized is the herbaceous or green bell pepper flavor caused by pyrazines, which are more prevalent in under-ripened grapes. Pyrazine compounds are present in all Cabernet Sauvignon grapes and are gradually destroyed by sunlight as the grape continues to ripen. To the human palate this compound is detectable in wines with pyrazine levels as low as 2 nanograms (ng) per liter. At the time of veraison, when the grapes first start to fully ripen, there is the equivalent pyrazine level of 30 ng/l. In cooler climates, it is difficult to get Cabernet Sauvignon grapes to ripen fully to the point where pyrazine is not detected. The green bell pepper flavor is not considered a wine fault but it may not be desirable to all consumers' tastes. The California wine region of Monterey was noted in the late 20th century for its very vegetal Cabernet Sauvignon with pronounced green pepper flavor, earning the nickname of "Monterey veggies". In addition to its cool climate, Monterey is also prone to being very windy, which can have the effect of shutting down the grape vines and further inhibiting ripeness. Two other well known flavors are mint and eucalyptus. Mint flavors are often associated with wine regions that are warm enough to have low pyrazine levels but are still generally cool, such as Australia's Coonawarra region and some areas of Washington State. There is some belief that soil could also be a contributor to the minty notes, since the flavor also appears in some wines from the Pauillac region but not from similar climate of Margaux. Resinous Eucalyptus flavors tend to appear in regions that are habitats for the eucalyptus tree, such as California's Napa and Sonoma valleys and parts of Australia, but there has been no evidence to conclusively prove a direct link between proximity of eucalyptus trees and the presence of that flavor in the wine.
One of the most noted traits of This great red wine is its affinity for oak, either during fermentation or in barrel aging. In addition to having a softening effect on the grape's naturally high tannins, the unique wood flavors of vanilla and spice complement the natural grape flavors of black currant and tobacco. The particular success of Cabernet-based Bordeaux blends in the 225 liter (59 gallon) barrique were a significant influence in making that barrel size one of the most popular worldwide. In winemaking, the decision for the degree of oak influence (as well as which type of oak) will have a strong impact on the resulting wine. American oak, particularly from new barrels, will impart stronger oak flavors that are less subtle than those imparted by French oak. Even within the American oak family, the location of the oak source will also play a role with oak from the state of Oregon having more pronounced influence on Cabernet Sauvignon than oak from Missouri, Pennsylvania and Virginia. Winemakers will often use a variety of oak barrels from different locations and of different ages and blend the wine as if they were blending different grape varieties. Winemakers can also control the influence of oak by using alternatives to the standard barrique barrels. Larger barrels will have a smaller wood-to-wine ratio and therefore less pronounced oak flavors. Winemakers in Italy and Portugal will sometimes use barrels made from other wood types such as chestnut and redwood. Another method that winemakers will consider tea bagging with oak chips or adding oak planks to the wines while fermenting or aging it in stainless steel tanks. While these methods are less costly than oak barrels, they create more pronounced oak flavors, which tend not to mellow or integrate with the rest of the wine's components; nor do they provide the gradual oxidation benefit of barrel aging.
