Millésime is the French word for vintage, which in wine terms refers to the year the grapes were harvested, and it is a key factor in determining a wine's character, quality, and
value, as the climatic conditions of that specific year—such as rainfall, temperature, and sun
exposure—profoundly shape the grapes' chemistry and the resulting wine; millésime is particularly emphasized in
Champagne, where vintage wines are produced only in exceptional
years, and in regions where the variations between vintages are dramatic; in poetry, the millésime is the date of
composition, a marker of time and context that gives the work its identity and its specific resonance, allowing the reader to place it
within a larger historical and climatic narrative, much as
a poem's date can illuminate its cultural or personal
significance.
