What reviewers say
“Fortified (Port-like) wine of SAR, Very nice to sip instead of original Ruby Port - quite dense, balanced 50/50 Syrah/Pinotage, harvested at optimal maturity and fermented in SS vats. Grape spirit added. Aged for 7 months in oak/inox . Deep dark cherry red, crimson rim.”

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 KWV Classic Collection Cape Ruby 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 Fortified · South Africa (29 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 141.
