Grape-treading or grape-stomping is part of the method of maceration used in traditional wine-making. [1] [2] [3] Rather than being crushed in a wine press or by another mechanized method, grapes are repeatedly trampled in vats by barefoot participants to release their juices and begin fermentation. Grape-treading was widespread in the history of winemaking, but with the introduction of industrial methods, it now survives mostly as a recreational or competitive activity at cultural festivals.
One of the earliest extant visual representations of the practice appears on a Roman Empire sarcophagus from the 3rd century AD, which depicts an idealized pastoral scene with a group of Erotes harvesting and stomping grapes at Vindemia, a rural festival. [4]
Many contemporary wineries hold grape-stomping contests to attract visitors. The practice is also the subject of many depictions in contemporary media, including the 1974 Mel Tillis song "Stomp Them Grapes", the I Love Lucy episode "Lucy's Italian Movie", and The Littlest Grape Stomper, [5] a children's book by Alan Madison. [6]
The novel The Secret of Santa Vittoria and the film based on it, taking place in a wine-producing Italian town during WWII, include a grape treading scene which has a major role in the battle of wits between the townspeople and their German occupiers.
Harvest experience tours, also known as "harvest internships" or "crush camps," are tours or programs that allow visitors to experience the winemaking process firsthand by participating in the grape harvesting and crushing process. These tours are usually offered during the grape harvesting season, which varies depending on the region and the type of grapes being harvested. Harvest experience tours can be a fun and educational way to learn about the winemaking process and to see behind the scenes at a working winery.
Winemaking, wine-making, 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.
A winery is a building or property that produces wine, or a business involved in the cultivation and production of wine, such as a wine company. Some wine companies own many wineries. Besides wine making equipment, larger wineries may also feature warehouses, bottling lines, laboratories, and large expanses of tanks known as tank farms. Wineries may have existed as long as 8,000 years ago.
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.
A winepress is a device used to extract juice from crushed grapes during winemaking. There are a number of different styles of presses that are used by wine makers but their overall functionality is the same. Each style of press exerts controlled pressure in order to free the juice from the fruit. The pressure must be controlled, especially with grapes, in order to avoid crushing the seeds and releasing a great deal of undesirable tannins into the wine. Wine was being made at least as long ago as 4000 BC; in 2011, a winepress was unearthed in Armenia with red wine dated 6,000 years old.
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.
Émile Peynaud was a French oenologist and researcher who has been credited with revolutionizing winemaking in the latter half of the 20th century, and has been called "the forefather of modern oenology".
The glossary of wine terms lists the definitions of many general terms used within the wine industry. For terms specific to viticulture, winemaking, grape varieties, and wine tasting, see the topic specific list in the "See also" section below.
The following outline is provided as an overview of and topical guide to wine:
Wine tourism is tourism whose purpose is or includes the tasting, consumption or purchase of wine, often at or near the source. Where other types of tourism are often passive in nature, enotourism can consist of visits to wineries, tasting wines, vineyard walks, or even taking an active part in the harvest.
The harvesting of wine grapes (vintage) is one of the most crucial steps in the process of wine-making. The time of harvest is determined primarily by the ripeness of the grape as measured by sugar, acid and tannin levels with winemakers basing their decision to pick based on the style of wine they wish to produce. The weather can also shape the timetable of harvesting with the threat of heat, rain, hail, and frost which can damage the grapes and bring about various vine diseases. In addition to determining the time of the harvest, winemakers and vineyard owners must also determine whether to use hand pickers or mechanical harvesters. The harvest season typically falls between August & October in the Northern Hemisphere and February & April in the Southern Hemisphere. With various climate conditions, grape varieties, and wine styles the harvesting of grapes could happen in every month of the calendar year somewhere in the world. In the New World it is often referred to as the crush.
Lesbos wine is wine made on the Greek island of Lesbos in the Aegean Sea. The island has a long history of winemaking dating back to at least the 7th century BC when it was mentioned in the works of Homer. During this time the area competed with the wines of Chios for the Greek market. An apocryphal account details one of the brothers of the poet Sappho as a merchant trading Lesbos wine with the Greek colony of Naucratis in Egypt. The most noted Lesbos wine was known as Pramnian which draws similarities today to the Hungarian wine Eszencia. The popularity of Lesbos wine continued into Roman times where it was highly valued along with other Aegean wines of Chios, Thasos and Kos.
Wickham Vineyards are a vineyard and wine maker in England, located in Wickham, Hampshire. Established in 1984, the vineyard occupies 18 acres (73,000 m2) of a 40-acre (160,000 m2) estate. One of the white wines, named "Fumé", that the vineyard produces is served as the United Kingdom House of Commons house wine.
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.
Western Australian wine refers to wine produced in Australia's largest state, Western Australia. Although the state extends across the western third of the continent, its wine regions are almost entirely situated in the cooler climate of its south-western tip. Western Australia produces less than 5% of the country's wine output, but in quality terms it is very much near the top, winning 30 percent of the country's medals.
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.
Breaux Vineyards is a Cajun owned and operated winery and vineyard located in Purcellville, Loudoun County, Virginia. Founded by E. Paul Breaux, Jr. in 1997, the 100% estate grown winery was one of three United States wineries to be named in the book "250 Best Wines 2012" by Oz Clarke for their Viognier, which landed at #87 in the publication. Breaux Vineyards is one of Virginia's largest grape growers & suppliers of wine grapes, bulk juice, and bulk wine to other East Coast U.S. wineries. The company logo is a red Crawfish, which pays homage to the Breaux family's Cajun heritage because they are often used in the local Cajun cuisine in Louisiana.
The history of the wine press and of pressing is nearly as old as the history of wine itself with the remains of wine presses providing some of the longest-serving evidence of organised viticulture and winemaking in the ancient world. The earliest wine press was probably the human foot or hand, crushing and squeezing grapes into a bag or container where the contents would ferment.
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.
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.
