What reviewers say
“Found a 2015 at Crafty for $13.99 and couldn't help but take a flyer on a ten year old wine at that price, even though it was dusty and stored upright on a shelf for God knows how long.”
From a top-rated Vivino review for this bottle.
Summary
An expressive and unique wine that brings an interesting mix of spice and fruit. Aromas recall roasted chiles at first, then smoke and granite, all plushly overlaying notes of plum and blackberry jam.
Polkura Syrah is a Chilean red made from Shiraz Syrah. At $21.99 for the lowest 750 ml listing, it belongs to the $15–30 band. It is bottled in Colchagua Valley.
1,569 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 1,607 reviewers with at least two ratings each feeds the raw-average track. The cohort it is ranked inside holds 444 Chilean reds.
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 Polkura Syrah 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 · Chile (444 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 1,569.
