A fine line separates the worlds of wine and beer. Fil is a seam stitched between these two worlds. A sparkling wine made with a type of yeast typically used for brewing beer. The natural formation of bubbles produced by bottle fermentation manifests itself in a multitude of threads of tiny bubbles that give their name to ‘vi d’agulla,’ literally ‘needle wine’ – subtle and persistent on the tongue and the palate. The name Fil means ‘thread’ in Catalan.
