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 Australia and British Columbia, Canada 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 and Spain, the grape spread across Europe and to the New World where it found new homes in places like California's Napa Valley, New Zealand's Hawke's Bay, South Africa's Stellenbosch region, Australia's Margaret River, McLaren Vale 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. However, by 2015, Cabernet Sauvignon had once again become the most widely planted wine grape, with a total of 341,000 hectares (3,410 km2) under vine worldwide.
Sauvignon blanc is a green-skinned grape variety that originates from the city of Bordeaux in France. The grape most likely gets its name from the French words sauvage ("wild") and blanc ("white") due to its early origins as an indigenous grape in South West France. It is possibly a descendant of Savagnin. Sauvignon blanc is planted in many of the world's wine regions, producing a crisp, dry, and refreshing white varietal wine. The grape is also a component of the famous dessert wines from Sauternes and Barsac. Sauvignon blanc is widely cultivated in France, Chile, Romania, Canada, Australia, New Zealand, South Africa, Bulgaria, the states of Oregon, Washington, and California in the US. Some New World Sauvignon blancs, particularly from California, may also be called "Fumé Blanc", a marketing term coined by Robert Mondavi in reference to Pouilly-Fumé.
Beaujolais is a French Appellation d'Origine Contrôlée (AOC) wine generally made of the Gamay grape, which has a thin skin and is low in tannins. Like most AOC wines they are not labeled varietally. Whites from the region, which make up only 1% of its production, are made mostly with Chardonnay grapes though Aligoté is also permitted until 2024. Beaujolais tends to be a very light-bodied red wine, with relatively high amounts of acidity. In some vintages, Beaujolais produces more wine than the Burgundy wine regions of Chablis, Côte d'Or, Côte Chalonnaise and Mâconnais put together.
Barolo is a red Denominazione di Origine Controllata e Garantita (DOCG) wine produced in the northern Italian region of Piedmont. It is made from the nebbiolo grape and is often described as one of Italy's greatest wines.
Winemaking or vinification is the production of wine, starting with the selection of the fruit, its fermentation into alcohol, and the bottling of the finished liquid. The history of wine-making stretches over millennia. The science of wine and winemaking is known as oenology. A winemaker may also be called a vintner. The growing of grapes is viticulture and there are many varieties of grapes.
Roussanne is a white wine grape grown originally in the Rhône wine region in France, where it is often blended with Marsanne. It is the only other white variety, besides Marsanne, allowed in the northern Rhône appellations of Crozes-Hermitage AOC, Hermitage AOC and Saint-Joseph AOC. In the southern Rhône appellation of Châteauneuf-du-Pape AOC it is one of six white grapes allowed, where it may be blended into red wines. Roussanne is also planted in various wine-growing regions of the New World, such as California, Washington, Texas, South Africa and Australia as well as European regions such as Crete, Tuscany and Spain.
Nebbiolo is an Italian red wine grape variety predominantly associated with its native Piedmont region, where it makes the Denominazione di Origine Controllata e Garantita (DOCG) wines of Barolo, Barbaresco, Roero, Gattinara, Carema and Ghemme. Nebbiolo is thought to derive its name from the Italian nebbia or Piedmontese nebia, meaning "fog". During harvest, which generally takes place late in October, a deep, intense fog sets into the Langhe region where many Nebbiolo vineyards are located. Alternative explanations refer to the fog-like glaucous veil that forms over the berries as they reach maturity, or that perhaps the name is derived instead from the Italian word nobile, meaning noble. Nebbiolo produces lightly-colored red wines which can be highly tannic in youth with scents of tar and roses. As they age, the wines take on a characteristic brick-orange hue at the rim of the glass and mature to reveal other aromas and flavours such as violets, tar, wild herbs, cherries, raspberries, truffles, tobacco, and prunes. Nebbiolo wines can require years of ageing to balance the tannins with other characteristics.
Barbera is a red Italian wine grape variety that, as of 2000, was the third most-planted red grape variety in Italy. It produces good yields and is known for deep color, full body, low tannins and high levels of acidity.
Viticulture or winegrowing is the cultivation and harvesting of grapes. It is a branch of the science of horticulture. While the native territory of Vitis vinifera, the common grape vine, ranges from Western Europe to the Persian shores of the Caspian Sea, the vine has demonstrated high levels of adaptability to new environments, hence viticulture can be found on every continent except Antarctica.
Late harvest wine is wine made from grapes left on the vine longer than usual. Late harvest is usually an indication of a sweet dessert wine, such as late harvest Riesling. Late harvest grapes are often more similar to raisins, but have been naturally dehydrated while on the vine.
Viognier is a white wine grape variety. It is the only permitted grape for the French wine Condrieu in the Rhône Valley.
Agiorgitiko is a red Greek wine grape variety that, as of 2012, was the most widely planted red grape variety in Greece, ahead of Xynomavro. The grape has traditionally been grown in the Nemea region of the Peloponnese but can be found throughout the country including Attikí (Attica) and Makedonía (Macedonia).
Piemonte wine is the range of Italian wines made in the region of Piedmont in the northwestern corner of Italy. The best-known wines from the region include Barolo and Barbaresco. They are made from the Nebbiolo grape. These wines are ideal for storage and a well-aged Barolo for instance may leave a feeling of drinking velvet because the tannins are polished and integrated more and more into the wine. As the wine matures the colour becomes more brownish and rust-red.
Friuli-Venezia Giulia wine is wine made in the northeastern Italian region of Friuli-Venezia Giulia. There are 11 Denominazione di origine controllata (DOC) and 3 Denominazione di Origine Controllata e Garantita (DOCG) in the Friuli-Venezia Giulia area. The region has 3 Indicazione Geografica Tipica (IGT) designations Alto Livenza, delle Venezie and Venezia Giulia. Nearly 62% of the wine produced in the region falls under a DOC designation. The area is known predominantly for its white wines which are considered some of the best examples of Italian wine in that style. Along with the Veneto and Trentino-Alto Adige/Südtirol, the Friuli-Venezia Giulia forms the Tre Venezie wine region which ranks with Tuscany and Piedmont as Italy's world class wine regions.
The annual growth cycle of grapevines is the process that takes place in the vineyard each year, beginning with bud break in the spring and culminating in leaf fall in autumn followed by winter dormancy. From a winemaking perspective, each step in the process plays a vital role in the development of grapes with ideal characteristics for making wine. Viticulturalists and vineyard managers monitor the effect of climate, vine disease and pests in facilitating or impeding the vine's progression from bud break, flowering, fruit set, veraison, harvesting, leaf fall and dormancy-reacting if need be with the use of viticultural practices like canopy management, irrigation, vine training and the use of agrochemicals. The stages of the annual growth cycle usually become observable within the first year of a vine's life. The amount of time spent at each stage of the growth cycle depends on a number of factors-most notably the type of climate and the characteristics of the grape variety.
The acids in wine are an important component in both winemaking and the finished product of wine. They are present in both grapes and wine, having direct influences on the color, balance and taste of the wine as well as the growth and vitality of yeast during fermentation and protecting the wine from bacteria. The measure of the amount of acidity in wine is known as the “titratable acidity” or “total acidity”, which refers to the test that yields the total of all acids present, while strength of acidity is measured according to pH, with most wines having a pH between 2.9 and 3.9. Generally, the lower the pH, the higher the acidity in the wine. There is no direct connection between total acidity and pH. In wine tasting, the term “acidity” refers to the fresh, tart and sour attributes of the wine which are evaluated in relation to how well the acidity balances out the sweetness and bitter components of the wine such as tannins. Three primary acids are found in wine grapes: tartaric, malic, and citric acids. During the course of winemaking and in the finished wines, acetic, butyric, lactic, and succinic acids can play significant roles. Most of the acids involved with wine are fixed acids with the notable exception of acetic acid, mostly found in vinegar, which is volatile and can contribute to the wine fault known as volatile acidity. Sometimes, additional acids, such as ascorbic, sorbic and sulfurous acids, are used in winemaking.
This glossary of viticultural terms list some of terms and definitions involved in growing grapes for use in winemaking.
In viticulture, ripeness is the completion of the ripening process of wine grapes on the vine which signals the beginning of harvest. What exactly constitutes ripeness will vary depending on what style of wine is being produced and what the winemaker and viticulturist personally believe constitutes ripeness. Once the grapes are harvested, the physical and chemical components of the grape which will influence a wine's quality are essentially set so determining the optimal moment of ripeness for harvest may be considered the most crucial decision in winemaking.
The Barossa Valley wine region is one of Australia's oldest and most premier wine regions. Located in South Australia, the Barossa Valley is about 56 km northeast of the city of Adelaide. Unlike most of Australia whose wine industry was heavily influenced by the British, the wine industry of the Barossa Valley was founded by German settlers fleeing persecution from the Prussian province of Silesia. The warm continental climate of the region promoted the production of very ripe grapes that was the linchpin of the early Australian fortified wine industry. As the modern Australian wine industry shifted towards red table wines in the mid-20th century, the Barossa Valley fell out of favor due to its reputation for being largely a Syrah from producers whose grapes were destined for blending. During this period the name "Barossa Valley" rarely appeared on wine labels. In the 1980s, the emergence of several boutique families specializing in old vine Shiraz wines began to capture international attention for the distinctive style of Barossa Shiraz, a full bodied red wine with rich chocolate and spice notes. This led to a renaissance in the Barossa Valley which catapulted the region to the forefront of the Australian wine industry.
Winemaking in Bordeaux is the collection of processes used to make Bordeaux wine. Winemaking in Bordeaux differs from winemaking in other places both because of the Bordelais climate and because of the particular Bordeaux style which the wine-maker is aiming for. A large number of processes are involved: pruning, training, spraying,, harvesting, (sorting), (de-stemming), crushing, fermentation, pressing, barrel-ageing, blending, bottling and bottle-ageing.
