What reviewers say
“4.7? Is it that good? Yes and no. But at least is really f*cking interesting! Matured in indigenous oak barrels, opened the 2019 at 2026 Boxing Day with chicken and vegetables as recommended by the very knowledgeable and passionate Julia.”
From a top-rated Vivino review for this bottle.
Summary
From Ahr in Germany, Bertram-Baltes Handwerk Spätburgunder is a red.
Its in-cohort standing is measured against 81 other reds from Germany, not against the corpus as a whole. The calibrated figure is built from 513 reviewers whose rating history varies enough to place their own average. A broader pool of 518 reviewers with two or more ratings feeds the raw-average track instead.
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 Bertram-Baltes Handwerk Spätburgunder 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 · Germany (82 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 513.
