What reviewers say
“Abundant flavour from the quality base wine, but, as yet, relatively little complexity. Smooth, fruity and nice bubbles. Best sparkling Shiraz with seafood or meat.”
From a top-rated Vivino review for this bottle.
Summary
Sorby Adams Morticia Sparkling Shiraz is a sparkling wine from Eden Valley, Australia.
Only 12 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 12 reviewers with at least two ratings feeds the raw-average track. 377 other sparkling wines from Australia form the cohort it is ranked inside.
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 Sorby Adams Morticia Sparkling Shiraz 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 Sparkling · Australia (378 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 12.
