Cloudburst Chardonnay is a small-production, highly regarded white wine from the Margaret River region of Western Australia. Cloudburst is a boutique winery celebrated for crafting some of Australia's most sought-after wines, with its Chardonnay consistently earning scores in the 94–97-point range from leading publications including Wine Advocate and James Suckling. Each bottle holds 750ml and the Costco listing represents a six-bottle case format.

The wine opens with aromas of lemon juice, chalk dust, and lime peel, with faint notes of butterscotch, powdered ginger, and savory complexity. On the palate it delivers wonderful tension and mouth-filling citrus and stony flavors with a silken texture and a long, building finish. Margaret River's warm, humid coastal climate — widely compared to Bordeaux — produces the exceptional Chardonnay fruit that defines Cloudburst's signature style. The wine is vinified with careful attention to terroir, resulting in a structured, age-worthy expression of Australian Chardonnay.
