Or insert, planks of wood, usually oak, placed in a stainless steel tank and held in position by a metal framework, are a way of imparting oak flavour to wine more cheaply than by fermenting or ageing in barrels since the staves are easily replaced.
Sometimes simply as botrytis, is the benevolent form of botrytis bunch rot, in which the Botrytis cinerea fungus attacks ripe, undamaged white wine grapes and, given the right weather, can result in extremely sweet grapes.
Chemicals applied to vineyards to control the growth of weeds. They may be either pre-emergent (or residual) or post-emergent (knockdowm). The latter group comprises two types, contact and syntemic herbicides. Residual herbicides act against germinating seedlings of the weeds, while post-emergent herbicides are applied only to the strip of ground directly under the vine, and weeds growing between the rows are controlled by cultivation or mowing.
Appellation abutting Gevrey-Chambertin in the Côte de Nuits district of Burgundy, producing red wines of a similar style to ist neighbour, though currently of lesser fame.
Is by German law a rosé wine at least 95% of which is made by direct pressing of a single red wine grape variety named on the label (Spätburgunder and Portugieser are especially common).
The general term used by winemakers to describe the harmless crystalline deposits that separate from wines during fermentation and ageing. The principal component of this deposit is potassium acid tartrate, the potassium salt of tartaric acid, which has therefore given rise to the name.
Named after the principal town of Nuits-St-Georges, this is the northern half of the escarpment of the Côte d'Or, producing the greatest red wines of Burgundy, from the Pinot Noir grape, and very occasional white wines.
Bouillie bordelaise in French, once much-used mixture of lime, copper sulfate, and water first recorded in 1885 by Alexis Millardet, as an effect control of downy mildew.
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.
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.
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.
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%).
The process of deliberately maturing a wine after bottling, whether for a few weeks as a conscious effort on the part of the bottler to allow the wine to recover from bottle sickness or, in the case of very fine wines, for many years in order to allow the wine to mature.
Widely used in filtration, is a naturally occuring, highly porous, chalky textured sedimentary rock made mainly of silica and consisting of fossilized remains of diatoms, a type of hard-shelled algae.
