What reviewers say
“Wow - what a difference😀👍… During „PechaKucha“ sessions we figured out that some members of the MGT-Team are wine lovers 😜👌! Back in the hotel i „Found“ this one on the table😎👍: Really nice and smooth nut, toasty and brioche flavors in the nose next to pear and lemon.”
From a top-rated Vivino review for this bottle.
Summary
Gingerbread, almond, hazelnut are balanced by fruit notes of peach and ripe apricots. The freshness on the palate comes from the Chardonnay in the blend and this brings elegance to the finished wine.
Castelnau Réserve Brut Champagne is a sparkling wine from Champagne, France. It blends Pinot Noir, Chardonnay and Pinot Meunier.
1,233 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 1,250 reviewers with at least two ratings each feeds the raw-average track. Its in-cohort standing is measured against 2,765 other sparkling wines 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 Castelnau Réserve Brut Champagne 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 Sparkling · France (2,766 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 1,233.
