Cabernet Franc
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 sometimes made into ice wine in those regions.
Cabernet Franc is lighter than Cabernet Sauvignon, making a bright pale red wine that contributes finesse and lends a peppery perfume to blends with more robust grapes. Depending on the growing region and style of wine, additional aromas can include tobacco, raspberry, bell pepper, cassis, and violets.
Records of Cabernet Franc in Bordeaux go back to the end of the 18th century, although it was planted in Loire long before that time. DNA analysis indicates that Cabernet Franc is one of two parents of Cabernet Sauvignon, Merlot, and Carménère.
Cabernet Franc shares many of the same phenolic and aroma compounds as Cabernet Sauvignon but with some noticeable differences. Cabernet Franc tends to be more lightly pigmented and produces wines with the same level of intensity and richness. Cabernet Franc tends to have a more pronounced perfume with notes of raspberries, blackcurrants, violets and graphite. It is often characterised by a green, vegetal strike that can range from leaves to green bell peppers. It has slightly less tannins than Cabernet Sauvignon and tends to produce a wine with a smoother mouthfeel. New World examples of Cabernet Franc tend to emphasise the fruit more and may delay harvesting the grapes to try to minimise the green leafy notes.

Cabernet Sauvignon
Cabernet Sauvignon is one of the world's most widely recognised 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 recognised through its prominence in Bordeaux wines where it is often blended with Merlot and Cabernet Franc. From France and Spain, the grape spread across Europe and to the New World where it found new homes in places like California's Santa Cruz Mountains, Paso Robles, Napa Valley, New Zealand's Hawkes Bay, South Africa's Stellenbosch region, 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 1990. However, by 2015, Cabernet Sauvignon had once again become the most widely planted wine grape.
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 a re hardy and naturally low yielding, budding late to avoid frost and resistant to viticultural hazards such as rot and insects - and to its consistent presentation of structure and flavours 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.
The classic profile of Cabernet Sauvignon tends to be full-bodied wines with high tannins and noticeable acidity that contributes to the wine's aging potential. In cooler climates, Cabernet Sauvignon tends to produce wines with blackcurrant notes that can be accompanied by green bell pepper notes, mint and cedar which will all become more pronounced as the wine ages. In more moderate climates the blackcurrant notes are often seen with black cherry and black olive notes while in very hot climates the currant flavours can veer towards the over-ripe and "jammy" side. In parts of Australia, particularly the Coonawarra wine region of South Australia, Cabernet Sauvignon wines tend to have a characteristic eucalyptus or menthol notes.
The style of Cabernet Sauvignon is strongly influenced by the ripeness of the grapes at harvest. When more on the unripe side, the grapes are high in pyrazines and will exhibit pronounced green bell peppers and vegetal flavours. When harvested overripe the wines can taste jammy and may have aromas of stewed blackcurrants. Some winemakers choose to harvest their grapes at different ripeness levels in order to incorporate these different elements and potentially add some layer of complexity to the wine. When Cabernet Sauvignon is young, the wines typically exhibit strong fruit flavours of black cherries and plum. The aroma of blackcurrants is one of the most distinctive and characteristic element of Cabernet Sauvignon that is present in virtually every style of the wine across the globe. Styles from various regions and producers may also have aromas of eucalyptus, mint and tobacco. As the wines age they can sometimes develop aromas associated with cedar, cigar boxes and pencil shavings. In general New World examples have more pronounced fruity notes while Old World wines can be more austere with heightened earthy notes.

Sangiovese
Sangiovese is a red Italian wine grape variety that derives its name from the Latin sanguis Jovis, "the blood of Jupiter". Though it is the grape of most of central Italy from Romagna down to Tuscany, Campania and Sicily, outside Italy it is most famous as the only component of Brunello di Montalcino and Rosso di Montalcino and the main component of the blends Chianti, Carmignano, Vino Nobile di Montepulciano and Morellino di Scansano, although it can also be used to make varietal wines such as Sangiovese di Romagna and the modern "Super Tuscan" wines like Tignanello.
Sangiovese was already well known by the 16th century. Recent DNA profiling by José Vouillamoz of the Istituto Agrario di San Michele all’Adige suggests that Sangiovese's ancestors are Ciliegiolo and Calabrese Montenuovo. The former is well known as an ancient variety in Tuscany, the latter is an almost-extinct relic from the Calabria, the toe of Italy. At least fourteen Sangiovese clones exist, of which Brunello is one of the best regarded. An attempt to classify the clones into Sangiovese grosso (including Brunello) and Sangiovese piccolo families has gained little evidential support.
Young Sangiovese has fresh fruity flavours of strawberry and a little spiciness, but it readily takes on oaky, even tarry, flavours when aged in barrels. While not as aromatic as other red wine varieties such as Pinot Noir, Cabernet Sauvignon, and Syrah, Sangiovese often has a flavour profile of sour red cherries with earthy aromas and tea leaf notes. Wines made from Sangiovese usually have medium-plus tannins and high acidity.
The high acidity and light body characteristics of the Sangiovese grape can present a problem for winemaking. The grape also lacks some of the colour-creating phenolic compounds known as acylated anthocyanins. Modern winemakers have devised many techniques trying to find ways to add body and texture to Sangiovese - ranging from using grapes that come from extremely low yielding vines, to adjusting the temperature and length of fermentation and employing extensive oak treatment. One historical technique is the blending of other grape varieties with Sangiovese, in order to complement its attractive qualities and fill in the gaps of some of its weaker points. The Sangiovese-based wines of Chianti have a long tradition of liberally employed blending partners—such as Canaiolo, Ciliegiolo, Mammolo, Colorino and even the white wine grapes like Trebbiano and Malvasia. Since the late 20th century, Bordeaux grapes, most notably Cabernet Sauvignon, have been a favoured blending partner though in many Italian DOC/DOCG regions there is often a maximum limit on the amount of other varietals that can be blended with Sangiovese; in Chianti the limit for Cabernet is 15%.
Other techniques used to improve the quality of Sangiovese include extending the maceration period from 7–12 days to 3–4 weeks to give the must more time to leach vital phenols out of the grape skins. Transferring the wine during fermentation into new oak barrels for malolactic fermentation gives greater polymerisation of the tannins and contributes to a softer, rounder mouthfeel. Additionally, Sangiovese has shown itself to be a "sponge" for soaking up sweet vanilla and other oak compounds from the barrel. For aging the wine, some modern producers will utilize new French oak barrels but there is a tradition of using large, used oak botti barrels that hold five to six hectolitres of wine. Some traditional producers still use the old chestnut barrels in their cellars.
