Coupage in French, is a practice that was once more distrusted than understood. In fact almost all of the world's finest wines are made by blending the contents of different vats and different barrels.
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.
Ancient word for steeping a material in liquid with or without a kneading action to separate the softened parts of the material from the harder ones. This important process in red winemaking involves extracion of the phenolics or anthocyanins, other glycosides, including flavour precursors from the grape skins, seeds, and stem fragments into the juice or new wine.
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.
French word for the process by which passerillé grapes are dried, shrivelled, or raisined on the vine, concentrating the sugar in grapes-an alternative to wines whose sugars have been concentrated by botrytis.
Is the winemaking operation of storing a fermented wine in wooden barrels to create ideal conditions for the components of the wine to evolve and so that the wood imparts some oak flavour.
Or bâtonnage, as it is called in French, is the once fashionable winemaking operation of mixing up the lees in a barrel, cask, tank or vat with the wine resting on them. It is an optional addition to the process of lees contact and is often employed, particularly for whites which have undergone barrel fermentation. Usually done with a stick. Stirring up the lees in the barrel also effects oak flavour.
French term for the intricate traditional method described in detail in sparkling winemaking. From 1994 the term was outlawed by EU authorities in favour of one of the following: méthode traditionelle; méthode classique; méthode traditionelle classique; fermented in this bottle and traditional method.
German term for young wine popularly consumed before botteling-generally cloudy and often still fermenting-and typically referred to in Austria as Sturm or Heuriger.
French term meaning "bled" for a winemaking technique which results in a rosé wine made by running off, or "bleeding", a certain amount of free-run juice from just-crushed dark-skinned grapes after a short, prefermentation maceration.
Increasingly popular and currently fashionable winemaking practice known to the Ancient Romans whereby newly fermented wine is deliberately left in contact with the lees. This period of lees contact may take place in any container, from a bottle to a large tank or vat-although a small oak barrel is the most common location for lees contact.
Direct Anglicization of the German Eiswein, sweet wine made from ripe grapes picked when frozen on the vine and pressed so that water crystals remain in the press and the sugar content of the resulting wine is increased. This sort of true ice wine is a speciality of Canada, where it is written Icewine. The word Icewine has been trademarked by VQA Canada which imposes the world's most stringent standards on the production. In Ontario, grapes for Icewine must have reached alt least 35° Brix. Residual sugar at bottling must be at least 125 g/l.
Widely misused term meaning strictly the climate within a defined and usually very restricted space or position. In viticulture, it might be at specific positions between rows of vines, or distances above the ground.
