The principal milk protein, is used by winemakers as a fining agent particularly useful for removing brown colours from white wines. It is used also in the clarification of young wines.
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.

Important village in the Côte de Nuits district of Burgundy producing red wines from Pinot Noir grapes. Morey suffers, perhaps unfairly, in comparison with ist neighbours Chambolle-Musigny and Gevrey-Chambertin beacuse its wines are usually described as being lighter versions of Gevrey or firmer than Chambolle, according to which side of the village they are located.
Or premier cru classé, is a cru judged of the first rank, usually according to some official classification.

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.
Spanish term used both to describe the process of ageing a wine and also for the youngest officially recognized category of a wood-matured wine. A crianza wine must have spent a minimum of six months in cask.

Sleep, the normal state of vines in winter. This period normally starts with autumn leaf fall, although buds are in a state of so-called organic dormancy from veraison onwards.
A common plant acid, abundant in some fleshy fruits such as lemons, but rare in grapes. The grape is unusual among fruits in that its major acid is tartaric acid, rather than citric acid, whose concentration in the juice of most grape varieties is only about one-twentieth that of tartaric acid.
Unregulated term of approbation referring to German Rieslings. Use of gold capsules to signify superior quality was a response, initially and still primarily in the Mosel, to the 1971 German Wine Law's prohibition on labels of traditional terms such as Cabinet, feine, feinste, or hochfeinste.
