A grape is a fruit, botanically a berry, of the deciduous woody vines of the flowering plant genus Vitis. Grapes are a non-climacteric type of fruit, generally occurring in clusters.
Wine is an alcoholic drink made from fermented fruit. Yeast consumes the sugar in the fruit and converts it to ethanol and carbon dioxide, releasing heat in the process. Wine is most often made from grapes, and the term "wine" generally refers to grape wine when used without any qualification. Even so, wine can be made from a variety of fruit crops, including plum, cherry, pomegranate, blueberry, currant, and elderberry.
Malvasia, also known as Malvazia, is a group of wine grape varieties grown historically in the Mediterranean region, Balearic Islands, Canary Islands and the island of Madeira, but now grown in many of the winemaking regions of the world. In the past, the names Malvasia, Malvazia, and Malmsey have been used interchangeably for Malvasia-based wines; however, in modern oenology, "Malmsey" is now used almost exclusively for a sweet variety of Madeira wine made from the Malvasia grape. Grape varieties in this family include Malvasia bianca, Malvasia di Schierano, Malvasia negra, Malvasia nera, Malvasia nera di Brindisi, Malvasia di Candia aromatica, Malvasia odorosissima, and a number of other varieties.
Sparkling wine is a wine with significant levels of carbon dioxide in it, making it fizzy. While it is common to refer to this as champagne, European Union countries legally reserve that word for products exclusively produced in the Champagne region of France. Sparkling wine is usually either white or rosé, but there are examples of red sparkling wines such as the Italian Brachetto, Bonarda and Lambrusco, and the Australian sparkling Shiraz. The sweetness of sparkling wine can range from very dry brut styles to sweeter doux varieties.
Table grapes are grapes intended for consumption while fresh, as opposed to grapes grown for wine production, juice production, or for drying into raisins.
Icewine is a type of dessert wine produced from grapes that have been frozen while still on the vine. The sugars and other dissolved solids do not freeze, but the water does, allowing for a more concentrated grape juice to develop. The grapes' must is then pressed from the frozen grapes, resulting in a smaller amount of more concentrated, very sweet juice. With icewines, the freezing happens before the fermentation, not afterwards. Unlike the grapes from which other dessert wines are made, such as Sauternes, Tokaji, or Trockenbeerenauslese, icewine grapes should not be affected by Botrytis cinerea or noble rot, at least not to any great degree. Only healthy grapes keep in good shape until the opportunity arises for an icewine harvest, which in extreme cases can occur after the New Year, on a northern hemisphere calendar. This gives icewine its characteristic refreshing sweetness balanced by high acidity. When the grapes are free of Botrytis, they are said to come in "clean". This results in a very complex and sweet wine. Much icewine is made from the grapes Riesling, Vidal, Cabernet Franc and Cabernet Sauvignon, but there is also icewine made from Shiraz, Merlot, Sangiovese and others.
Pinot gris, Pinot grigio or Grauburgunder is a white wine grape variety of the species Vitis vinifera. Thought to be a mutant clone of the pinot noir variety, it normally has a pinkish-gray hue, accounting for its name, but the colors can vary from blue-gray to pinkish-brown. The word pinot could have been given to it because the grapes grow in small pinecone-shaped clusters. The wines produced from this grape also vary in color from a deep golden yellow to copper and even a light shade of pink, and it is one of the more popular grapes for skin-contact wine.
A varietal wine is a wine made primarily from a single named grape variety, and which typically displays the name of that variety on the wine label. Examples of grape varieties commonly used in varietal wines are Cabernet Sauvignon, Chardonnay and Merlot. Wines that display the name of two or more varieties on their label, such as a Chardonnay-Viognier, are blends and not varietal wines. The term is frequently misused in place of vine variety; the term variety refers to the vine or grape, while varietal refers to the wine produced by a variety.
Tempranillo is a black grape variety widely grown to make full-bodied red wines in its native Spain. Its name is the diminutive of the Spanish temprano ("early"), a reference to the fact that it ripens several weeks earlier than most Spanish red grapes. Tempranillo has been grown on the Iberian Peninsula since the time of Phoenician settlements. It is the main grape used in Rioja, and is often referred to as Spain's noble grape. The grape has been planted throughout the globe's wine regions.
The Muscat family of grapes includes over 200 grape varieties belonging to the Vitis vinifera species that have been used in wine production and as raisin and table grapes around the globe for many centuries. Their colors range from white, to yellow, to pink to near black. Muscat grapes and wines almost always have a pronounced floral aroma. The breadth and number of varieties of Muscat suggest that it is perhaps the oldest domesticated grape variety, and there are theories that most families within the Vitis vinifera grape variety are descended from the Muscat variety.
Bacchus is a white wine grape created by viticulturalist Peter Morio at the Geilweilerhof Institute for Grape Breeding in the Palatinate in 1933. He crossed a Silvaner x Riesling cross with Müller-Thurgau.
The German wine classification system puts a strong emphasis on standardization and factual completeness, and was first implemented by the German Wine Law of 1971. Nearly all of Germany's vineyards are delineated and registered as one of approximately 2,600 Einzellagen, and the produce from any vineyard can be used to make German wine at any quality level, as long as the must weight of the grapes reaches the designated minimum level. As the current German system does not classify vineyards by quality, the measure of wine ’quality’ is the ripeness of the grapes alone.
Italian wine is produced in every region of Italy. Italy is the country with the widest variety of indigenous grapevine in the world, with an area of 702,000 hectares under vineyard cultivation, as well as the world's second largest wine producer and the largest exporter as of 2023. Contributing 49.8 million hl of wine in 2022, Italy accounted for over 19.3% of global production, ahead of France (17.7%) and Spain (13.8%); the following year, production decreased by 11.5 million hl, and Italy was surpassed by France. Italian wine is also popular domestically among Italians, who consume a yearly average of 46.8 litres per capita, ranking third in world wine consumption.
Greece is one of the oldest wine-producing regions in the world and among the first wine-producing territories in Europe. The earliest evidence of Greek wine has been dated to 6,500 years ago where wine was produced on a household or communal basis. In ancient times, as trade in wine became extensive, it was transported from end to end of the Mediterranean; Greek wine had especially high prestige in Italy under the Roman Empire. In the medieval period, wines exported from Crete, Monemvasia and other Greek ports fetched high prices in northern Europe.
French wine is produced all throughout France, in quantities between 50 and 60 million hectolitres per year, or 7–8 billion bottles. France is one of the largest wine producers in the world, along with Italian, Spanish, and American wine-producing regions. French wine traces its history to the 6th century BCE, with many of France's regions dating their wine-making history to Roman times. The wines produced range from expensive wines sold internationally to modest wines usually only seen within France such as the Margnat wines of the post-war period.
Wine has been produced in the United States since the 1500s, with the first widespread production beginning in New Mexico in 1628. As of 2023, wine production is undertaken in all fifty states, with California producing 80.8% of all US wine. The North American continent is home to several native species of grape, including Vitis labrusca, Vitis riparia, Vitis rotundifolia, and Vitis vulpina, but the wine-making industry is based almost entirely on the cultivation of the European Vitis vinifera, which was introduced by European settlers. With more than 1,100,000 acres (4,500 km2) under vine, the United States is the fourth-largest wine producing country in the world, after Italy, Spain, and France.
Blauer Portugieser is a red Austrian, Slovenian wine, Croatian wine, Moravian and German wine grape found primarily in the Rheinhessen, Pfalz and wine regions of Lower Austria, Slovenia and Croatia. It is also one of the permitted grapes in the Hungarian wine Egri Bikavér. In Germany, the cultivated area covered 4,551 hectares or 4.5% of the total vineyard area in 2007. Wine cellars usually vinify a simple light red wine, which is characterized by a fresh, tart and light body. It is also frequently vinified as a rosé. Blauer Portugieser is also very well suited as table grapes; however, it is not sold as such because the selling of wine grapes as table grapes is not permitted in the European Union. Since 2000, higher quality wines have been vinified from Portugieser grapes. The use of oak provides additional aromas in order to compete with Bordeaux varieties. DNA profiling has shown that Blauer Portugieser is a cross between Grüner Silvaner and Blaue Zimmettraube. Historical ampelographic sources have provided very solid evidence that the geographic area of origin of the variety is Lower Styria.
The classification of wine is based on various criteria including place of origin or appellation, vinification method and style, sweetness and vintage, and the grape variety or varieties used. Practices vary in different countries and regions of origin, and many practices have varied over time. Some classifications enjoy official protection by being part of the wine law in their country of origin, while others have been created by, for example, growers' organizations without such protection.
In viticulture, the yield is a measure of the amount of grapes or wine that is produced per unit surface of vineyard, and is therefore a type of crop yield. Two different types of yield measures are commonly used, mass of grapes per vineyard surface, or volume of wine per vineyard surface.
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.
