Our Team

Guided by the expert hand of award-winning winemaker Penny Gadd-Coster, the sisters are dedicated to sparkling and still winemaking in the time-honored French method. By employing this méthode champenoise—the traditional second fermentation in the bottle—and using the finest select Pinot Noir, Pinot Meunier, and Chardonnay grapes, Breathless sparkling wines pair beautifully with all of life’s moments, from the everyday to the extraordinary.
