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.

Grenache
Grenache or Garnacha is one of the most widely planted red wine grape varieties in the world. It ripens late, so it needs hot, dry conditions such as those found in Spain, where the grape most likely originated. It is also grown in the Italian isle of Sardinia, the south of France, Australia, and California's Monterey AVA and San Joaquin Valley.
It is generally spicy, berry-flavoured and soft on the palate and produces wine with a relatively high alcohol content, but it needs careful control of yields for best results. Characteristic flavour profiles on Grenache include red fruit flavours (raspberry and strawberry) with a subtle, white pepper spice note. Grenache wines are highly prone to oxidation, with even young examples having the potential to show browning (or "bricking") coloration that can be noticed around the rim when evaluating the wine at an angle in the glass. As Grenache ages the wines tend to take on more leather and tar flavours. Wines made from Grenache tend to lack acid, tannin and colour, and it is often blended with other varieties such as Syrah, Carignan, Tempranillo, and Cinsaut.
In Spain, there are mono-varietal wines made of Garnacha tinta (red Grenache), notably in the southern Aragon wine regions of Calatayud, Carinena and Campo de Borja, but it is also used in blends, as in some Rioja wines with tempranillo. Grenache is the dominant variety in most Southern Rhône wines, especially in Châteauneuf-du-Pape, where it is typically over 80% of the blend. In Australia it is typically blended in "GSM" blends with Syrah (commonly known as Shiraz in that country) and Mourvèdre with old vine examples in McLaren Vale. In Italy, the Sardinian D.O.C. wine Cannonau di Sardegna is by law 90% local Grenache (Cannonau). Grenache is also used to make rosé wines in France and Spain, notably those of the Tavel district in the Côtes du Rhône and those of the Navarra region. And the high sugar levels of Grenache have led to extensive use in fortified wines, including the red vins doux naturels of Roussillon such as Banyuls, and as the basis of most Australian fortified wine.
Grenache is often used as a blending component, adding body and sweet fruitiness to a wine. The grape can be troublesome for the winemaker due to tendency to oxidize easily and lose colour. To compensate for the grape's naturally low tannins and phenolic compounds, some producers will use excessively harsh pressing and hot fermentation with stems to extract the maximal amount of colour and phenols from the skins. This can backfire to produce green, herbaceous flavours and coarse, astringent wine lacking the grape's characteristic vibrant fruitiness. To maintain those character traits, Grenache responds best to a long, slow fermentation at cooler temperatures followed by a maceration period. To curb against oxidation, the wine should be racked as little as possible. The use of new oak barrels can help with retaining colour and preventing oxidation but too much oak influence can cover up the fruitiness of Grenache.
The high levels of sugars and lack of harsh tannins, makes Grenache well adapted to the production of fortified wines, such as the vin doux naturels (VDN) of the Roussillon region and the "port-style" wines of Australia. In these wines, the must ferments for three days before grape spirit is added to the must to halt the fermentation and the conversion of sugar into alcohol. The high alcoholic proof grape spirit brings the finished wine up to 15–16% alcohol. These wines can be made in a rancio style by being left outside in glass demi-johns (or carboys) or wooden barrels where the wine bakes in the sun for several years until it develops a maderized character and flavours of sour raisins, nuts and cheese. These fortified VDNs and port-style wines have longevity and can be drinkable well into their third decade.

Merlot
Merlot is a dark blue-coloured 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 colour 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.
Along with Cabernet Sauvignon, Cabernet Franc, Shiraz Cabernet, Malbec and Petit Verdot, Merlot is one of the primary grapes used in Bordeaux wine, and it is the most widely planted grape in the Bordeaux wine regions. Merlot is also one of the most popular red wine varietals in many markets. This flexibility has helped to make it one of the world's most planted grape varieties. As of 2004, Merlot was estimated to be the third most grown variety at 260,000 hectares (640,000 acres) globally. The area planted to Merlot has continued to increase, with 266,000 hectares (660,000 acres) in 2015.
While Merlot is made across the globe, there tend to be two main styles. The "International style" favoured by many New World wine regions tends to emphasise late harvesting to gain physiological ripeness and produce inky, purple coloured wines that are full in body with high alcohol and lush, velvety tannins with intense, plum and blackberry fruit. While this international style is practiced by many Bordeaux wine producers, the traditional "Bordeaux style" of Merlot involves harvesting Merlot earlier to maintain acidity and producing more medium-bodied wines with moderate alcohol levels that have fresh, red fruit flavours (raspberries, strawberries) and potentially leafy, vegetal notes.
As a varietal wine, Merlot can make soft, velvety wines with plum flavours. While Merlot wines tend to mature faster than Cabernet Sauvignon, some examples can continue to develop in the bottle for decades. There are three main styles of Merlot - a soft, fruity, smooth wine with very little tannins; a fruity wine with more tannic structure; and, finally, a brawny, highly tannic style made in the profile of Cabernet Sauvignon. Some of the fruit notes commonly associated with Merlot include cassis, black and red cherries, blackberry, blueberry, boysenberry, mulberry, olallieberry and plum. Vegetable and earthy notes include black and green olives, cola nut, bell pepper, fennel, humus, leather, mushrooms, rhubarb and tobacco. Floral and herbal notes commonly associated with Merlot include green and black tea, eucalyptus, laurel, mint, oregano, pine, rosemary, sage, sarsaparilla and thyme. When Merlot has spent significant time in oak, the wine may show notes of caramel, chocolate, coconut, coffee bean, dill weed, mocha, molasses, smoke, vanilla and walnut.
