One of the most important wine rivers, linking a range of vineyards as dissimilar as those of Châteauneuf-du Pape in southern France, sparkling Seyssel, and Fendant du Valais in Switzerland.
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.
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.

Or premier cru classé, is a cru judged of the first rank, usually according to some official classification. The direct translation of the French term premier cru, much used in the context of Bordeaux, is first growth.

Winemaking technique of fermenting grape juice or must in small barrels rather than in a larger fermentation vessel. The technique is used principally for white wines because of the difficulty of extracting through a barrel's small bung-hole the mass of skins and seeds which necessarily remains after red wine fermentation.
Winemaking process with the aim of clarification and stabilization of a wine whereby a fining agent, one of a range of special materials, is added to coagulate or adsorb and precipitate quickly the colloids suspended in it.
