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. There is evidence that suggests that the earliest wine production took place in Georgia and Iran around 6000 to 5000 B.C. 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.
Pomace, or marc, is the solid remains of grapes, olives, or other fruit after pressing for juice or oil. It contains the skins, pulp, seeds, and stems of the fruit.
Carbonic maceration is a winemaking technique, often associated with the French wine region of Beaujolais, in which whole grapes are fermented in a carbon dioxide rich environment before crushing. Conventional alcoholic fermentation involves crushing the grapes to free the juice and pulp from the skin with yeast serving to convert sugar into ethanol. Carbonic maceration ferments most of the juice while it is still inside the grape, although grapes at the bottom of the vessel are crushed by gravity and undergo conventional fermentation. The resulting wine is fruity with very low tannins. It is ready to drink quickly but lacks the structure for long-term aging. In extreme cases such as Beaujolais nouveau, the period between picking and bottling can be less than six weeks.
Red wine is a type of wine made from dark-colored grape varieties. The color of the wine can range from intense violet, typical of young wines, through to brick red for mature wines and brown for older red wines. The juice from most purple grapes is greenish-white, the red color coming from anthocyan pigments present in the skin of the grape. Much of the red wine production process involves extraction of color and flavor components from the grape skin.
A rosé is a type of wine that incorporates some of the color from the grape skins, but not enough to qualify it as a red wine. It may be the oldest known type of wine, as it is the most straightforward to make with the skin contact method. The pink color can range from a pale "onionskin" orange to a vivid near-purple, depending on the grape varieties used and winemaking techniques. Usually, the wine is labelled rosé in French, Portuguese, and English-speaking countries, rosado in Spanish, or rosato in Italian.
Maceration is the winemaking process where the phenolic materials of the grape—tannins, coloring agents (anthocyanins) and flavor compounds—are leached from the grape skins, seeds and stems into the must. To macerate is to soften by soaking, and maceration is the process by which the red wine receives its red color, since raw grape juice is clear-grayish in color. In the production of white wines, maceration is either avoided or allowed only in very limited manner in the form of a short amount of skin contact with the juice prior to pressing. This is more common in the production of varietals with less natural flavor and body structure like Sauvignon blanc and Sémillon. For Rosé, red wine grapes are allowed some maceration between the skins and must, but not to the extent of red wine production.
The following outline is provided as an overview of and topical guide to wine:
The process of fermentation in winemaking turns grape juice into an alcoholic beverage. During fermentation, yeasts transform sugars present in the juice into ethanol and carbon dioxide. In winemaking, the temperature and speed of fermentation are important considerations as well as the levels of oxygen present in the must at the start of the fermentation. The risk of stuck fermentation and the development of several wine faults can also occur during this stage, which can last anywhere from 5 to 14 days for primary fermentation and potentially another 5 to 10 days for a secondary fermentation. Fermentation may be done in stainless steel tanks, which is common with many white wines like Riesling, in an open wooden vat, inside a wine barrel and inside the wine bottle itself as in the production of many sparkling wines.
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, the Friuli-Venezia Giulia forms the Tre Venezie wine region, which ranks with Tuscany and Piedmont as Italy's world class wine regions.
Ribolla Gialla is a white wine grape grown most prominently in the Friuli Venezia Giulia region of northeast Italy. The grape is also found in Slovenia, where it is known as Rebula. In Friuli Venezia Giulia, the grape thrives in the region around Corno di Rosazzo and Gorizia. In Slovenia, the grape is grown prominently in the Brda region. The grape is not related to the Friuli red wine grape Schioppettino, which is also known as Ribolla Nera. The obscure, lower quality Ribolla Verde grape is a mutated version that is not widely used.
The Gorizia Hills is a hilly microregion in western Slovenia and northeastern Italy. It lies on the right bank of the Soča (Isonzo) River, north of the Italian town of Gorizia, after which it is named. The region covers around 120 km2 (46 sq mi) and has about 7,000 inhabitants, mostly ethnic Slovenes, with a small number of Friulian speakers in its westernmost part.
The Colli Orientali del Friuli is a Denominazione di origine controllata (DOC) located in the Italian wine region of Friuli Venezia Giulia. The region is located in the province of Udine and is sub-divided into three main sections; Ramandolo in the north, Cialla and Corno di Rosazzo. The climate and soil is very similar to the neighboring DOC of Collio Goriziano and the two region share many winemaking similarities as well. The main distinction between the Colli Orientali del Friuli and Collio Goriziano lie in the increased red and dessert wine production of the Colli Orientali del Friuli. The region also includes within its boundaries the three Denominazione di origine controllata e garantita (DOCG) of the Friuli Venezia Giulia Ramandolo and the two passito wine DOCGs of Colli Orientali del Friuli Picolit and Colli Orientali del Friuli Picolit-Cialla.
This glossary of winemaking terms lists some of terms and definitions involved in making wine, fruit wine, and mead.
In winemaking, pressing is the process where juice is extracted from the grapes with the aid of a wine-press, by hand, or even by the weight of the grape berries and clusters. Historically, intact grape clusters were trodden by feet but in most wineries today the grapes are sent through a crusher/destemmer, which removes the individual grape berries from the stems and breaks the skins, releasing some juice, prior to being pressed. There are exceptions, such as the case of sparkling wine production in regions such as Champagne where grapes are traditionally whole-cluster pressed with stems included to produce a lighter must that is low in phenolics.
The color of wine is one of the most easily recognizable characteristics of wines. Color is also an element in wine tasting since heavy wines generally have a deeper color. The accessory traditionally used to judge the wine color was the tastevin, a shallow cup allowing one to see the color of the liquid in the dim light of a cellar. The color is an element in the classification of wines.
Vino novello, Italian for 'young wine', is a light, fruity, red wine produced throughout Italy. Novello is similar to its French cousin Beaujolais nouveau in taste, body and color, but is produced using several grape varieties with a more liberal fermentation process. While historically released for sale on November 6, Novello is since 2012 available on 30 October.
Kvevri or Qvevri - also known as Ch'uri in Western Georgia - are large earthenware vessels used for the fermentation, storage and ageing of traditional Georgian wine. Resembling large, egg-shaped amphorae without handles, they are either buried below ground or set into the floors of large wine cellars. Kvevris vary in size: volumes range from 20 litres to around 10,000; 800 is typical.
The role of yeast in winemaking is the most important element that distinguishes wine from fruit juice. In the absence of oxygen, yeast converts the sugars of the fruit into alcohol and carbon dioxide through the process of fermentation. The more sugars in the grapes, the higher the potential alcohol level of the wine if the yeast are allowed to carry out fermentation to dryness. Sometimes winemakers will stop fermentation early in order to leave some residual sugars and sweetness in the wine such as with dessert wines. This can be achieved by dropping fermentation temperatures to the point where the yeast are inactive, sterile filtering the wine to remove the yeast or fortification with brandy or neutral spirits to kill off the yeast cells. If fermentation is unintentionally stopped, such as when the yeasts become exhausted of available nutrients and the wine has not yet reached dryness, this is considered a stuck fermentation.
Collio Goriziano is an Italian wine and winemaking region in northeast Italian region of Friuli Venezia Giulia, located in the northernmost part of the Province of Gorizia, in the Italian part of the Gorizia Hills, which extend to neighboring Slovenia. It has been recognized with the official the status of DOC. Colli Goriziano predominantly produces white wines with Friulano, Ribolla Gialla, Malvasia Istriana, Chardonnay, Pinot bianco, Pinot grigio, and Sauvignon blanc being the leading varietals. Red wine is also produced under the Collio Rosso designation and is usually a blend of Merlot, Cabernet Franc, and Cabernet Sauvignon.
