Slight fizziness caused by the carbon dioxide formed during fermentation. Most noticeable in wines that have been refrigerated during fermentation.
A wine with slight residual gas in it. Usually attractive in light young whites, but in reds it is often a sign of refermentation in bottle
a taste sensation derived from small amounts of residual carbon dioxide in wines. Often a prickly character can be noticed in white wines fermented cold (the lowering of the temperature tends to integrate more carbon dioxide than usual); its appreciation is relative to the individual taster.
