2023 Diatom Chardonnay Santa Barbara

Published: Jun 14, 2025 by Editor · 3 Comments

2023 Diatom Chardonnay Santa Barbara

This is an exciting find at Costco; a highly rated Chardonnay under $20 that we have yet to try.

The ratings for this wine are beyond impressive and consistent. 94 from Dunnuck who is our favorite. 93 points from Spectator, Decanter and Suckling. And they're not wrong.

The wine hits Costco for $18.99 and looks to be going online for $23-$25.

The wine pours a medium gold in the glass with aromas of citrus and wild flowers. Flavors of white peach, lemon, green apple, pineapple come through beautifully and clean. Plenty of body, with balance and complexity throughout.
