What reviewers say
“I am a big fan of this red Portuguese cuvee! Found at Grocery Outlet for under $10, this is a hit with everyone who tries it.”
From a top-rated Vivino review for this bottle.
Summary
Intense and concentrated color. A complex aroma of chocolate and cocoa with ripe red fruits, well integrated into the new wood that gives notes of spices. In the mouth, it has good structure, with elegant tannins and a good volume, with notes of bitter chocolate and coffee. The ending is long and persistent.
Guarda Rios Tinto is a red from Ribatejo, Portugal, blended from Trincadeira, Aragonez, Alicante Bouschet and Shiraz Syrah. At $10.99 for the lowest 750 ml listing, it belongs to the under $15 band.
The calibrated figure is built from 2,513 reviewers whose rating history varies enough to place their own average. A broader pool of 2,692 reviewers with two or more ratings feeds the raw-average track instead. Its in-cohort standing is measured against 350 other reds from Portugal, 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 Guarda Rios 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 2,513.
