A full body folds in bright citrus, lemon zest and mineral flavors in this mouth-filling yet balanced and nicely chalky wine. Lemon pith, wet stones and vivid acidity on the palate.

The 2025 Chardonnay is yet another compelling edition of this wine, with generous curves, enticing florality and prickly acidity. Gorgeous aromas of jasmine, orange blossom and white peach press from the glass, soaking into the palate with staining density and a delectable lick of salinity on the finish. This is more of a standalone, singular wine than it is a “Chardonnay,” but that happens to be a huge success. In 2025, the Diatom Chardonnay comes across like an aromatic white, but with Chardonnay’s texture and structure. At this scale of production, how can you go wrong?

Winemaker Notes

Aromas of lemon, citrus blossom, and wet sand with flavors of saline and white peach. The texture is precise and balanced.

About the Winery

Diatom specializes in only one variety—Chardonnay— and is motivated by the pursuit of subtraction and refinement. Fermented at low temperatures in small stainless-steel tanks, coupled with inhibited malolactic fermentation and short hose transportation, diatom intends to capture Chardonnay in its most raw, carnal state. Winemaker Greg Brewer strives to imbue recognition of place with as little disturbance, distraction or interference as possible. The resulting wines have a sense of transparency and a purity of intent and purpose.
