Syrah, also known as Shiraz, is a dark-skinned grape variety grown throughout the world and used primarily to produce red wine. In 1999, Syrah was found to be the offspring of two obscure grapes from southeastern France, Dureza and Mondeuse Blanche. Syrah should not be confused with Petite Sirah, a cross of Syrah with Peloursin dating from 1880.
Retsina is a Greek white resinated wine, which has been made for at least 2,000 years. Its unique flavor is said to have originated from the practice of sealing wine vessels, particularly amphorae, with Aleppo pine resin in ancient times. Before the invention of impermeable glass bottles, oxygen caused many wines to spoil within the year. Pine resin helped keep air out, while infusing the wine with resin aroma. The Romans began to use barrels in the 3rd century AD, removing any oenological necessity for resin, but the flavor itself was so popular that the style is still widespread today.
Oak is used in winemaking to vary the color, flavor, tannin profile and texture of wine. It can be introduced in the form of a barrel during the fermentation or aging periods, or as free-floating chips or staves added to wine fermented in a vessel like stainless steel. Oak barrels can impart other qualities to wine through evaporation and low level exposure to oxygen.
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.
Assyrtiko or Asyrtiko is a white Greek wine grape indigenous to the island of Santorini. Assyrtiko is widely planted in the arid volcanic-ash-rich soil of Santorini and other Aegean islands, such as Paros. It is also found on other scattered regions of Greece such as Chalkidiki. Assyrtiko is also being grown by Jim Barry Wines in Clare Valley, South Australia, at the Abbey of New Clairvaux in Northern California since 2011, and at Kefi Winery in Monroe, North Carolina by a first generation Greek family. The original Assyrtiko cuttings were imported in the USA in 1948 by Harold Olmo, grape breeder at the University of California, Davis, where they were stored until the abbey of New Clairvaux took interest in the early 2000s.
Arbois or Arbois Blanc is a white French wine grape variety planted primarily in the Loire regions. Despite being a minor grape, in the late 20th century it was the third most widely planted grape variety in the Loir-et-Cher département which includes the winemaking areas of Cheverny, Cour-Cheverny, Montrichard, Oisly, Saint-Romain-sur-Cher, Valençay as well as vineyards that make wines under the Touraine AOC, Cremant de Loire AOC and Vin de Pays du Loir et Cher. By 2004 acreage had steadily declined to around 750 acres. It is still a permitted grape variety in the Appellation d'origine contrôlée (AOC) regions of Cheverny AOC, Valençay AOC and Vouvray AOC.
Marzemino is a red Italian wine grape variety that is primarily grown around Isera, south of Trentino. The wine is most noted for its mention in the opera Don Giovanni of Wolfgang Amadeus Mozart. The vine ripens late and is susceptible to many grape diseases including oidium. Wine produced from the grape has a characteristic dark tint and light plummy taste.
Petit Manseng is a white wine grape variety that is grown primarily in South West France. It produces the highest quality wine of any grape in the Manseng family. The name is derived from its small, thick skin berries. Coupled with the small yields of the grapevine, most Petit Manseng farmers produce around 15 hl of wine per hectare. The grape is often left on the vine till December to produce a late harvest dessert wine. The grape is grown primarily in Gascony, Jurançon and around Madiran but has recently drawn interest in New World wine regions like California, North Georgia, Virginia, and Ohio. In May 2020, CSIRO scientists discovered through DNA analysis that Australia's plantings of Petit Manseng, first imported in 1979, are in fact Gros Manseng. The reason is that it is expected to follow Viognier's path to popularity among white wine drinkers. It was already present in Uruguay, when Basque settlers brought "Manseng" and Tannat vines with them to their new home. Despite being easily recognizable as a white grape while true Manseng is a black grape, wine that is Petit Manseng is still normally labeled as just "Manseng". The grape is often left on the vine to produce a late harvest wine made from its nearly raisin like grapes.
Pignolo is a red Italian wine grape grown predominantly in the Friuli-Venezia Giulia region of northeast Italy. Believed to have been cultivated in the hills of Rosazzo, the grape is now a prominent variety in the Colli Orientali del Friuli Denominazione di origine controllata (DOC). In Italian the grape's name originates from pigna, because the grapes are dense like pine cones. The first recorded mention of the grape was in Abbot Giobatta Michieli's late 17th century book Bacchus in Friuli in which he described the grape making "excellent black wine". Today the grape is used to make rich, deep colored, full bodied wine that does well with some time in oak. Well made examples of the wine have good balance between the grape's acidity and tannins with flavor notes of plum and blackberry. Most experts believe that it is not related to the Lombardy Pignola grape of the Valtellina region.
Savatiano (or Savvatiano) is a white Greek wine grape used primarily in the wine Retsina. It is one of Greece's most widely planted grape varieties and is known for its resistance to drought condition. It is mostly planted throughout central Greece, particularly in Attica near Athens. In Retsina, the naturally low acidity of the grape is sometimes compensated for by the addition of Assyrtiko and Rhoditis in the blend.
Rhoditis is a pink-skinned Greek wine grape traditionally grown in the Peloponnese region of Greece. The grape was highly valued in the Greek wine industry prior to the phylloxera outbreak due to its ability to ripen late and maintain its acidity in hot climates like those of Peloponnese and Thessaly. However its susceptibility to powdery mildew and phylloxera dramatically reduced it plantings throughout the 20th century. Today it is most commonly blended with Savatiano in making the Greek wine Retsina.
Athiri or Athiri Aspro is a white Greek wine grape used to make Retsina on the island of Rhodes.
Grechetto or Grechetto bianco is a white Italian wine grape variety of Greek origins. The grape is planted throughout central Italy, particularly in the Umbria region where it is used in the Denominazione di origine controllata (DOC) wine Orvieto and Denominazione di origine controllata (DOC) wine Valdichiana Toscana. It is primarily a blending grape, though some varietal wine is also produced. Grechetto is commonly blended with Chardonnay, Malvasia, Trebbiano and Verdello. The grape's thick skin provides good resistance to downy mildew which can attack the grape late in the harvest season. This makes Grechetto a suitable blending grape in the production of Vin Santo.
Ancient Rome played a pivotal role in the history of wine. The earliest influences on the viticulture of the Italian peninsula can be traced to ancient Greeks and the Etruscans. The rise of the Roman Empire saw both technological advances in and burgeoning awareness of winemaking, which spread to all parts of the empire. Rome's influence has had a profound effect on the histories of today's major winemaking regions in France, Germany, Italy, Portugal and Spain.
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.
Baroque is a white French wine grape planted primarily in South West France around the Tursan region. It can make full bodied wines with nutty flavors. Ampelographers suspect that the grape maybe a crossing of Folle Blanche and Sauvignon blanc.
Dimyat is a white Bulgarian wine grape. It is one of Bulgaria's most widely planted white grape varieties, second only to Rkatsiteli. Wines made from this variety are noted for their perfume aromas. While some ampelographers believe that the variety is indigenous to Bulgaria, legends have developed around Dimiat being named after a city in the Nile Delta and was brought back to Europe by Crusaders in the Middle Ages.
Old World wine refers primarily to wine made in Europe but can also include other regions of the Mediterranean basin with long histories of winemaking such as North Africa and the Near East. The phrase is often used in contrast to "New World wine" which refers primarily to wines from New World wine regions such as the United States, Australia, South America and South Africa. The term "Old World wine" does not refer to a homogeneous style with "Old World wine regions" like Austria, France, Georgia, Italy, Portugal, and Spain each making vastly different styles of wine even within their own borders. Rather, the term is used to describe general differences in viticulture and winemaking philosophies between the Old World regions where tradition and the role of terroir lead versus the New World where science and the role of the winemaker are more often emphasized. In recent times, the globalization of wine and advent of flying winemakers have lessened the distinction between the two terms with winemakers in one region being able to produce wines that can display the traits of the other region—i.e. an "Old World style" wine being produced in a New World wine region like California or Chile and vice versa.
In winemaking, clarification and stabilization are the processes by which insoluble matter suspended in the wine is removed before bottling. This matter may include dead yeast cells (lees), bacteria, tartrates, proteins, pectins, various tannins and other phenolic compounds, as well as pieces of grape skin, pulp, stems and gums. Clarification and stabilization may involve fining, filtration, centrifugation, flotation, refrigeration, pasteurization, and/or barrel maturation and racking.
