Definizione

Breakdown of dead yeast cells in a wine, giving a rich flavor, structure and body to wines like champagne, and those made from chardonnay or sauvignon blanc. 1

Nota

Autolysis may be defined by a loss of dry matter, a decrease in the percentage of protein and nucleic acids in this dry matter, and by an intracellular proteolytic activity. The yeast strain and its preparation influence autolysis in wine [...]. 2 During the bottle ageing process the yeast cells autolyse, releasing increasingly complex flavour compounds. The longer a wine rests on the lees of the second fermentation in bottle, the more chance it has of picking up flavour from the dead yeast cells, a process known as yeast autolysis. [...] 3

Contesto

Hydrogen sulfide produced as a result of autolysis will destroy a wine. 4
