What reviewers say
“What's not to like? Extremely smooth, fruity and balanced, wood is subtle but clearly there. Been on the racks for 5.5 years and frankly brilliant”
From a top-rated Vivino review for this bottle.
Summary
From Western Cape in South Africa, Boplaas Cape Vintage Reserve Port is a fortified wine.
Its in-cohort standing is measured against 28 other fortified wines from South Africa, not against the corpus as a whole. 201 Vivino reviewers rate with enough spread for a personal baseline to be measured, and those are the ones the calibrated score reads; a separate, broader pool of 202 reviewers with at least two ratings each feeds the raw-average track.
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 Boplaas Cape Vintage Reserve Port 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 · South Africa (29 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 201.
