What reviewers say
“Deep garnet colour. 60% Cabernet Sauvignon 40% Merlot blend Third Growth Grand Cru Classe Chateau Blason D’Issan from Margaux situated next to Chateau Palmer. In 2017 there were heavy frosts but Clos D’Issan was protected by the wall that surrounds the estate and was spared.”
From a top-rated Vivino review for this bottle.
Summary
Château d'Issan Blason d'Issan Margaux is a red from Margaux, France. At $32.92 for the lowest 750 ml listing, it belongs to the $30–60 band.
The calibrated figure is built from 3,206 reviewers whose rating history varies enough to place their own average. A broader pool of 3,259 reviewers with two or more ratings feeds the raw-average track instead. Its in-cohort standing is measured against 71 other reds from France, 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 Château d'Issan Blason d'Issan Margaux 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 Red · Francia (72 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 3,206.
