Tasting profile
A powerful, full-bodied Shiraz layered with jammy plum, dark and dried fruits, vanilla oak, black pepper, chocolate and tobacco, carried by discreet tannins and gentle acidity. Rich, syrupy and well-balanced with a long finish, it drinks youthfully for its age and still has years of cellaring ahead.
Synthesized from 839Vivino reviewers' tasting notes for this bottle.

Summary
Yalumba The Octavius Old Vine Shiraz is a red from Barossa, Australia.
The calibrated figure is built from 839 reviewers whose rating history varies enough to place their own average. A broader pool of 859 reviewers with two or more ratings feeds the raw-average track instead. Its in-cohort standing is measured against 516 other reds from Australia, 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 Yalumba The Octavius Old Vine 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 Red · Australia (517 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 839.
