What reviewers say
“This amazing Cabernet comes from the Northern Mayacamas region in Red Hills of Lake County & is named for the glassy black volcanic rock covering the steep slopes of the vineyard which produces a bold, well structured wine. Deep purple throughout in color with long legs.”
From a top-rated Vivino review for this bottle.
Summary
Brambly and dark with hints of cocoa powder. Rich and generous in the mouth, this wine features notes of black cherries mixed with blackberries and is soft yet voluminous. The concentration is representative of the third year of drought in California, creating dense, layered flavors that hold on the palate.

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 Obsidian Ridge Estate Grown Cabernet Sauvignon 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 2,453.
