Fonseca 2017 is a classic Vintage Port. PortDB models its drinking window as opening in 2037, remaining prime through 2081, and declining from 2109. That window starts with the opulent maturation style assigned to Fonseca, then adjusts for the classic vintage tier.

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.
