Diatom logo


With Diatom, Winemaker Greg Brewer seeks to capture Chardonnay in its most pure and unadulterated state. Diatom is named for diatomaceous earth, which is a plankton fossil found in the oceanic landscape of Santa Barbara County.



"Diatom is motivated by the pursuit of subtraction and refinement. It is the polishing of a grain of rice until one has reached its ultimate inner core. Our Sta. Rita Hills marine landscape is stark and so are the wines of its provenance. We strive for a 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."
