Diatom Chardonnay Santa Barbara County Unoaked 2024 750ml

Diatom Chardonnay — Santa Barbara County 2024

Greg Brewer's Diatom project is built on a single, radical idea: subtraction. No oak barrels. No malolactic fermentation. No extended aging. Just 100% Chardonnay from Santa Barbara County, fermented and aged six months in stainless steel, stripped of everything that typically softens, butters, or blurs the grape. What remains is electric — a wine that tastes like the soil and the sea. The name itself is a clue: diatomaceous earth, the plankton fossil-rich geology beneath Santa Barbara's vineyards, is the terroir this wine is designed to express. Jeb Dunnuck awarded it 94 points and called it "a no-brainer purchase." Wine Spectator followed at 93, James Suckling at 93, Wine Enthusiast at 92, and Wine Advocate at 90. Across the board, the verdict is the same: this is one of California's most precise and honest Chardonnays.

The nose is vivid and pure: exotic citrus, minty herbs, oyster shell, honeydew rind, lime candy, and a whisper of sea spray. On the palate, it is sleek and taut — ripe pear, ginger, pomelo, and brisk lime zest coiled around a mouthwatering thread of acidity. Salinity and minerals run through the finish alongside springtime blossoms and a lingering kick of melon pith. It gains weight and richness with time in the glass without ever losing its electric freshness.
