French term used to describe grapes which have been dried, or partially dried, before fermentation to increase the sugar content. It is used most commonly in Switzerland and occasionally in the Valle d'Aosta.
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.
Before concrete, stainless steel, and other inert materials replaced wood as the most common material for wine fermentation vessels and storage containers in the 1960s, each wine region had ist own legion of barrel types. Even today such terms as feuillette, tonneau, and fudre may be used to measure volumes of wine long after the actual containers themselves have been abandoned.
System of fractional blending used most commonly in Jerez for maintaining the consistency of a style of Sherry which takes ist name from those barrels closest to the suelo, or floor, from which the final blend was customarily drawn.
The final addition to a sparkling wine which may top up a bottle in the case of traditional method wines, and also determines the sweeteness, or residual sugar, of the finished wine. A mixture of wine and sugar syrup.
Extremely popular sparkling wine made in the region of Veneto, located north-east of Italy. The DOC was once an IGT. To ensure that no one outside the region was able to jump on the luctrative Prosecco bandwagon, the grape variety was renamed Glera in 2009, and Prosecco was registered as a protected denomination of origin DOC.
An accumulation of clay and silt particles that have been deposited by the wind. Loess is typically pale-coloured, unstratified, and loosely cemented by calcium carbonate. Favoured for viticulture because it is porous, permeable, readily warmed and easily penetrated by roots.
Is a complex of sensations resulting from the shrinking, drawing, or puckering of the tissues of the mouth. The most important astringent materials are tannins.
Microscopic, single-celled fungi, having round to oval cells which reproduce by forming buds, are vital to the alcoholic fermentation process, which, starved of oxygen, transforms grape juice to wine.
In the dialect of the north west Italian region of Piemonte, indicates the highest part of an elevation in the landscapeor, in particular, a vineyard with a steep gradient at the top of a hill.
Large and prosperous village in the Côte de Beaune district of Burgundy's Côte d'Or producing mostly white wines from the Chardonnay grape. Although Meursault contains no Grand Cru vineyards, the quality of white burgundy from Meursault's best Premier Crus is rarely surpassed.
Very large group of highly reactive chemical compounds of which phenol is the basic building block. These include many natural colour pigments such as the anthocyanins of fruit and dark-skinned grapes, most natural vegetable tannins such as occur in grapes, and many flavour compounds.
Imprecise tasting term used in many languages for a distinctive style of wine, often fortified wine or vin doux naturel, achieved by deliberately maderizing the wine by exposing it to oxygen and/or heat.
Meaning literally "yellow wine" in French, extraordinary style of wine made in France, mainly in the Jura region, using a technique similar to that used for making Sherry but without fortification.
Ultratradaitional method of red wine fermentation in which grape berries are not subjected to destemming. This was the default position before the introduction of the crusher-destemmer. The possible disadvantages are that, unless the stems are vey ripe, i.e. well lignified, and the must is handled very gently, the stems may impart harsh tannins to the wine.
Increasingly fashionable and aims at reducing the exposure of must and wine to oxygen in the winery by minimizing or eliminating practices such as racking, lees stirring, and the use of new oak barrels.
