Dow's 2017 is a classic Vintage Port. PortDB models its drinking window as opening in 2039, remaining prime through 2084, and declining from 2119. That window starts with the structured maturation style assigned to Dow's, then adjusts for the classic vintage tier.
Drinking window
Opens 2039 · prime to 2084 · declining from 2119
For this bottle, the model opens the window 22 years after the vintage and gives it a 45-year prime phase before the mature tail. Decline is modelled 102 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.
