What reviewers say

Charmé par cette version revisité du Porto Rubis Reserva que l’on doit a David Guimaraens l’héritier trublion et 6 ème génération de cette vénérable institution qui chamboule la tradition après des études d’oeunologie en Australie et Oregon. Une robe sombre aux reflets châtain.

From a top-rated Vivino review for this bottle.

Summary

Fonseca Bin 27 Reserve Port is a fortified wine from Porto, Portugal. The cheapest 750 ml listing found for it is $19.94, which puts the bottle in the $15–30 band.

2,130 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 2,175 reviewers with at least two ratings each feeds the raw-average track. 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 Fonseca Bin 27 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 · 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 2,130.
