Anadia, the small Bairrada town at the heart of this region, calls itself the 'Sparkling Wine Capital' of Portugal — the area produces roughly two-thirds of the country's espumante using the same traditional method as Champagne.
Espumante da Bairrada is a traditional-method sparkling wine made mainly from the local Bical and Maria Gomes grapes, grown on Bairrada's clay-limestone soils between the Mondego and Vouga rivers. It's crisp, high in acidity, with fine persistent bubbles, ranging from bone-dry to demi-sec.
