Tasting profile
A rich, sweet 20-year tawny showing raisin, caramel, chocolate and marzipan, with a smoky note from extended barrel aging. Reviewers describe it as deceptively light and balanced, easy to drink despite its layered, concentrated character.

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.

- Where Blackett 20 Anos Port lands against every wine we rank.
- In-cohort percentile

- 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 162.
