Producer of Maine Wild Blueberry Sparkling Wine Thoreau called wild blueberries “bluets” and wrote of their innocent ambrosial taste, as if made of the ether itself. Bluet sparkling wine captures summer in Maine with the purity of a single ingredient: native Maine wild blueberries. Fermented and bottled in the Méthode Champenoise tradition, Bluet is naturally bubbly, dry, and can be served as an apéritif or mixed in a cocktail.
