This, to me, is the closest to Champagne you'll get outside of that region and price tag. There are many sparkling wines available in Ireland today, some excellent, some just fizzy grape juice. Cava is Spain's equivalent to Champagne, in that it is made in the same way.
It took a while to find the Andreu family, who have been dedicated to growing vines since the 18th century. In 1991, Carles Andreu, continuing the family tradition, established the winery that bears his name. His is a small bodega in the village of Pira, housed in the old-manor house of Cal Celdoni. The fermentation tanks are where the wines used to be fermented many years ago.
