Tasting profile
A semi-sweet, smooth port showing prunes, figs, and a hint of spice on both nose and palate, with good fruit and balanced acidity that keeps it fresh rather than syrupy. Reviewers describe it as delicate, long-lasting on the finish, and well-suited to aging a few more years.

What reviewers say
“Prunes, figs and spices in the nose and on the palate. Delicate and long lasting in the mouth, still enough acidity to keep it fresh.”

Summary
Offley Vintage Port Boa Vista is a fortified wine from Porto, Portugal.
The calibrated figure is built from 261 reviewers whose rating history varies enough to place their own average. A broader pool of 268 reviewers with two or more ratings feeds the raw-average track instead. Its in-cohort standing is measured against 1,421 other fortified wines from Portugal, not against the corpus as a whole.
How the score was built
We compare the reviewers of this bottle against every other wine those same people reviewed. Each review is scored relative to the reviewer's own baseline — four stars from someone who hands out fives means something very different from four stars from someone who rarely goes above three. Every reviewer then counts the same, so the result is a calibrated consensus rather than a star average.
- Global percentile
- Where Offley Vintage Port Boa Vista lands against every wine we rank.
- In-cohort percentile
- The same comparison narrowed to its cohort — wines of the same type from the same country. A Chilean red is judged against Chilean reds, not against Champagne. Ranked against Fortified · Portugal (1,422 wines).
- AI-adjusted percentile
- The same reviewer-normalized score, corrected for how much confidence the sample supports: thin samples are pulled toward the corpus average. Each wine keeps the share n / (n + 53) of its measured distance from the average, where n is its calibrated-reviewer count, and the result is ranked on the same scale as the global percentile.53 is the median sample size across everything we rank. Here n is 261.
