What reviewers say
“Um tinto DOURO D.O.C. que surpreende pela cor rubi densa, muito escura e opaca, fazendo por momentos parecer que estamos perante um vinho de cor preta, de tão escuro que é. No nariz notamos frutos maduros e suaves notas de madeira.”
From a top-rated Vivino review for this bottle.
Summary
Violet color and rich aroma of red fruit (cherry and plum) combined with mocha notes and smoke from a well-integrated wood. In the mouth confirmed that the aromatic notes and highlights is a lively acidity and firm tannins. Its finish is long and elegant.
From Douro in Portugal, Quinta da Fronteira Tinto is a red. It blends Touriga Nacional, Touriga Franca and Tinta Roriz.
Its in-cohort standing is measured against 350 other reds from Portugal, not against the corpus as a whole. 1,527 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 1,579 reviewers with at least two ratings each feeds the raw-average track.
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 Quinta da Fronteira Tinto 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 · Portugal (351 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 1,527.
