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.
Occasionally madeirization, is the process by which a wine is made to taste like Madeira, involving mild oxidation over a long period and, usually, heat.
Common winemaking practice, named after its French promulgator Jean-Antoine Chaptal, whereby the final alcoholic strength of a wine is increased by addition of sugar to the grape juice or must, before and/or during fermentation, although if it is added before, the higher sugar level will make it harder for the yeast to multiply.
The most famous northern Rhône appellation of all, producing extremely limited quantities of seriously long-lived reds and about a third as much full-bodied dry white wine which some believe is even more distinguished.

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.

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.
Northernmost appellation of the Côte de Nuits district of the Côte d'Or. It is unique in Burgundy for having Appellation Contrôllée status for red, white, and pink wines.
