Fonseca 1992 is a classic Vintage Port. PortDB models its drinking window as opening in 2012, remaining prime through 2056, and declining from 2084. That window starts with the opulent maturation style assigned to Fonseca, then adjusts for the classic vintage tier.
Drinking window
Opens 2012 · prime to 2056 · declining from 2084
For this bottle, the model opens the window 20 years after the vintage and gives it a 44-year prime phase before the mature tail. Decline is modelled 92 years after the harvest.

The vintage tier is an editorial judgement based on critic consensus; the drinking window is PortDB’s model, not a measurement. Storage and bottle variation can move the practical window.
