“Robe : orangé, trouble, non filtré, quelques particules en suspension, bulles extrêmement fines Nez : fruits blancs, odeur de ferme, légèrement fumé, notes d'agrumes Bouche : très léger, légère acidité, notes d'abricot et de peche, court en bouche avec une fin tout en douceur sur une agrume moins aggressive que celle du pamplemousse et sur des notes tropicales comme celle de l'ananas Vin très léger à boire sans soif, en apéro uniquement, trop léger pour accompagner un plat Bonne surprise”
From a top-rated Vivino review for this bottle.
Summary
Duckman Maria Duck Pet Nat is a Portuguese sparkling wine made from Fernao Pires. It comes from Bairrada, in Portugal.
174 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 174 reviewers with at least two ratings each feeds the raw-average track. Its in-cohort standing is measured against 192 other sparkling 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 Duckman Maria Duck Pet Nat 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 · Portugal (193 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 174.
