What reviewers say
“Winter melon, citrus, and a hint of oak on the nose. Quite shy, but opens up. Palate holds good weight - medium acidity that folds relatively quickly, but showing citrus zest, yellow peach, lemon and nectarine flavours. A really lovely weighted and balanced textural mouthfeel from the zesty acidity, and extended lees contact. The latter adding plenty to this wine. Value.”
From a top-rated Vivino review for this bottle.

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 Stellenzicht Wines Thunderstone Chardonnay 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 White · Zuid-Afrika (94 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 154.
