This term has two meanings in viticulture:
Climatic phenomenon (inversion) in which the temperature, which normally decreases with altitude, increases abruptly at a barrier layer. Due to fog formation, it remains cold in the valley, but above the cloud line it is sunny and warmer. See also Climate and Weather.
Term for the conversion (also hydrolysis) of the multiple sugar type sucrose into its two building blocks or single sugar types fructose (fruit sugar) and glucose (grape sugar). See also invertase and invert sugar.
The Wine lexicon helps me to keep up to date and refresh my knowledge. Thank you for this Lexicon that will never end in terms of topicality! That's what makes it so exciting to come back often.
