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.
Qualitätswein is what POD wines are called in German. This is Germany's largest and lowest wine category and in practice includes all those wines once known as QbA. The grapes must originate in one of Germany's 13 official wine regions and reach minimum must weights.

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.
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.
Translates directly from French as a wine that is naturally sweet. Vins doux naturels are made by mutage, by artificially arresting the conversion of grape sugar to alcohol by adding spirit before fermentation is complete.
Important commercial centre on the River Saône and capital of the Mâconnais dynamic district of Burgundy which produces considerable quantities of white wine and some red.
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%).
Occasionally RS, the total quantity of sugars remaining unfermented in the finished wine. This may include both fermentable sugars, mainly glucose and fructose, which have for some reason remained unconverted to alcohol during fermentation, and small amounts of those few sugars which are not readily fermented by typical wine yeast.
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.
Or premier cru classé, is a cru judged of the first rank, usually according to some official classification.

An element that is extremely important in wine production. The addition of sulfur dioxide during crushing and pressing deactivates enzymes that catalyse oxidation, which leads to juice browning and modification of aromas and flavours, which is why it is often added to freshly picked grapes in the salt form of metabisulfite. (The compound is widely, often more liberally, used in the preparation of other foods and drinks, particularly in fruit juices and dried fruits).
