Rather negative description (also decrepit, superimposed) for a wine in the context of a wine address after it has passed its peak in development and is now constantly degrading and losing quality. The cause is chemical changes with ultimately negative effects on aroma, colour and taste. However, the wine is still enjoyable with restrictions. The clearly negative "final stage" is described as dead (undrinkable). Another meaning is the term Alterston (also Altl). See regarding the ageing process of wines under the keywords ageing and bottle ageing, and regarding the optimal time of consumption under drinking maturity.
The Wine lexicon helps me to stay 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 visit more often.Thorsten Rahn
