What reviewers say
“Well well well, 10 years have done this wine wonders. Dark ruby colour. Initially the nose has that very heavy oak and vanilla aroma that you find with so many Spanish reds but it softens with being left to breathe.”
From a top-rated Vivino review for this bottle.
Summary
From Rioja in Spain, Ontañón Rioja Reserva is a red. It blends Grenache Noir and Tempranillo. The cheapest 750 ml listing found for it is $29.99, which puts the bottle in the $15–30 band.
904 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 926 reviewers with at least two ratings each feeds the raw-average track. Its in-cohort standing is measured against 434 other reds from Spain, 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 Ontañón Rioja Reserva 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 · Spain (435 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 904.
