What reviewers say
“Simply put, this is an excellent bottle of wine. Deep red in color, it presents immediately a nose of oak and cherry and sprawling syrupy legs. The palate then is in for a real delight: notes of spiced apple, raspberry, strawberry, bacon, smoke...the list goes on!”
From a top-rated Vivino review for this bottle.
Summary
Ruby red color coats the glass. Slightly floral with a punch of concentrated plum, dark berry fruit and orange peel. Dense and rich, an unforgettable saturation of voluptuous, jammy flavors fold together. Sweet layers of black fruit build depth on the back palate. Finishing with nuances of vanilla and boysenberry jam that encourage another taste.
Rombauer Vineyards Zinfandel Napa Valley is an American red from Napa Valley.
Its in-cohort standing is measured against 1,155 other reds from the United States, not against the corpus as a whole. 867 Vivino reviewers rate with enough spread for a personal baseline to be measured, and those are the ones the calibrated score reads; a separate, broader pool of 917 reviewers with at least two ratings each feeds the raw-average track.
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 Rombauer Vineyards Zinfandel Napa Valley 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 · United States (1,156 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 867.
