Fermented in the bottle and aged for 12 months on the lees before release, this wine is the best of both worlds. It consistently delivers premium flavors and for the price of a regular bottle of Brut Non-vintage French Champagne you can take home three or four bottles of this gem. Casteller literally translates as ?tower.? The name is a reference to a local Catalonian summer game where different clans compete to create the tallest human tower.
