What reviewers say
“3.9pts. Casa Defra 4 Generazioni Pinot Grigio 2021. More fruity and crisp than expected, its pleasant acidity promotes appetite. The name Casa Defra means “the house of the brothers”, and it reflects the family’s tradition and passion for wine-making. The 4 Generazioni line of wines is a tribute to the four generations of the Cielo family who have dedicated themselves to the art of wine-making. The wines are made with selected grapes and express the typical characteristics of their terroir.”

Summary
Casa Defrà 4 Generazioni Pinot Grigio is an Italian white from delle Venezie.

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 Casa Defrà 4 Generazioni Pinot Grigio 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 · Italien (819 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 266.
