What reviewers say
“Beau Chardonnay argentin. Le nez est généreux sur les notes typiques du cépage, mêlant fruits blancs et une très belle touche huileuse. En bouche, l’attaque est vive et acidide, tandis que la texture huileuse apporte du gras et de la rondeur.”
From a top-rated Vivino review for this bottle.
Summary
Séptima Obra Reserva Chardonnay is an Argentine white from Mendoza.
Only 33 of its Vivino reviewers rate with enough spread for a personal baseline to be measured, so the calibrated figure rests on a thin sample; a broader pool of 33 reviewers with at least two ratings feeds the raw-average track. 397 other whites from Argentina form the cohort it is ranked inside.
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 Séptima Obra Reserva Chardonnay 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 White · Argentina (398 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 33.
