What reviewers say
“Fave Margaret river chardy no question. Nice full mouth with butter, little bit of oak and a great citrus driven acidity. Real terroir. 98 points”
From a top-rated Vivino review for this bottle.
Summary
Si Vintners Halcyon Vineyard Chardonnay is a white from Margaret River, Australia.
Its in-cohort standing is measured against 1,360 other whites from Australia, not against the corpus as a whole. Only 20 of its Vivino reviewers rate with enough spread for a personal baseline to be measured, so the calibrated figure rests on a thin sample; a broader pool of 20 reviewers with at least two ratings 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 Si Vintners Halcyon Vineyard 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 · Australia (1,361 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 20.
