One of the most important wine rivers, linking a range of vineyards as dissimilar as those of Châteauneuf-du Pape in southern France, sparkling Seyssel, and Fendant du Valais in Switzerland.
Affects vines when air temperatures are high. Very high daytime temperatures, of more than 40°C/104°F, cause the vine to "shut down", or virtually cease photosynthesis, as the enzymes responsible can no longer work. High temperatures also lead to water stress, especially when accompained by bright sunshine, low humidity, and strong, dry winds.
Means literally "late harvest" and in France is restricted to Alsace, where strict regulations cover ist production, even if too many producers are meeting only the bare minima.
Or Le Montrachet, the most famous Grand Cru white burgundy, the apogee of the Chardonnay grape produced from a single vineyard in the Côte de Beaune district of the Côte d'Or.

Is Europe and the rest of the Mediterranean basin such as the Near East and North Africa. The term is used solely in contrast to the New World, the Old World having little sense of homogeneity. Old World techniques in vineyard and cellar have relied more on tradition and less on science than in the New World.
Of a wine is ist total concentration of volatile acids, those naturally occuring organic acids of wines that are separable by distillation. Wine's most common volatile acid by far is acetic acid (more than 96%).
Contrasts with protective and reductive winemaking in that the winemaker deliberately exposes the wine to oxygen at various stages in the winemaking process in order to encourage certain reactions and achieve a particular style of wine. Oloroso Sherry being an extreme example.
French term for racking, or moving clear wine off ist sediment and into a clean container. It can also be used for the wine serving process of decanting.
Downy mildew attacks all green parts of the vine and young leaves are particularly susceptible. When severly affected, leaves will drop off. The loss of leaves reduces photosynthesis and thus causes delays in fruit ripening and, typically, levels of fruit sugars, vine reserves of carbohydrates, and anthocyanins are depressed.
Term much used in the wine world, initially smoewhat patronizingly but with increasing admiration in the last quarter of the 20th century as the New World's share of global exports rose from 3 to 23%, to distinguish the colonies established as a result of the longer voyages in the 15th century.
An expression for that part of the Bordeaux wine region that is on the left bank of the river Garonne. It includes, travelling down river, Graves, Sauternes, Barsac, Pessac-Léognan, Médoc and all the appellations of the Médoc.
Literally "individual site" in the wine regions of Germany. Almost all of Germany's vineyards are officially registered as one of these approximately 2600 Einzellagen, which can vary in size from a fraction of 1 ha to more than 200 ha/494 acres. As in Burgundy, for example, the Einzellagen may be divided among many different owners.
