What reviewers say

Marto famously said, "If you like this, you're f'cked up in the head" . Manna, a co-ferment of Portugieser and Scheurebe, undergoes whole cluster pressing and is aged for a year in old neutral oak barrels.

From a top-rated Vivino review for this bottle.

Summary

Marto Manna is a German red from Rheinhessen. The blend is Scheurebe and Blauer Portugieser.

13 other reds from Germany form the cohort it is ranked inside. The calibrated figure is built from 215 reviewers whose rating history varies enough to place their own average. A broader pool of 217 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 Marto Manna 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 · Deutschland (14 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 215.
