What reviewers say
“Douro tinto português reserva encorpado, presente, alcoólico. Vinho de cor bem escura, lembrando um marsala escuro, com halos acastanhados que remetem aos 12 meses em barricas de carvalho. Lágrimas densas, grossas e lentas, que remetem aos seus 14% de graduação alcoólica.”
From a top-rated Vivino review for this bottle.
Summary
Porca de Murca Reserva Tinto is a red from Douro, Portugal. It is made from Touriga Nacional.
350 other reds from Portugal form the cohort it is ranked inside. 2,740 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 2,864 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 Porca de Murca Reserva 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 2,740.
