The stressed syllable (marked with 1) is pronounced louder and clearer than others.

Quick Definition

Autolysis is the breakdown of yeast cells after fermentation, contributing creamy textures and bready aromas to sparkling wines aged on lees.

Detailed Definition
In verse, autolysis represents transformation through decay and self-dissolution. The yeast giving up its substance to enrich the wine becomes an image of sacrificial creation. Poets may invoke it to discuss how loss feeds beauty, how death nourishes life, and how patience allows hidden depths to emerge from apparent ruin, mirroring processes of grief, maturity, and artistic refinement.
Example
Example in poetry:
Autolysis whispered in the lees, a slow decomposition the poet likened to bread rising in the dark; He wrote that autolysis gave the sparkling wine its brioche soul, a yeast-death that became flavor-birth; In her elegy for the dead yeast, autolysis was the alchemy of rot into richness, a funeral that feasts; The poet compared autolysis to the digestion of grief—time breaking down sharp edges into creamy acceptance; She imagined the lees as a silent classroom where autolysis taught patience to the young wine
Additional Notes
Autolysis is the biochemical process of yeast cells breaking down after fermentation has ceased, releasing intracellular components such as amino acids, enzymes, and polysaccharides into the wine, which imparts creamy, bready, and toasty notes that are especially prized in high-quality sparkling wines produced by the traditional method; this process occurs during the extended aging period on the lees (sur lie), lasting from several months to many years, and it softens the wine's texture, adds complexity, and contributes to the fine, persistent mousse of Champagne and its equivalents; for poetry students, autolysis offers a metaphor for transformation through dissolution—the death of the yeast giving life to the wine's secondary aromas, much as the poet's previous drafts and discarded lines fertilize the final poem, making it richer and more nuanced, a slow, invisible maturation that cannot be rushed.
