Sparkling Txakoli! A joint project between Artadi and Zapiain, a Basque Cider producer. With grapes grown in the Getariako zone over looking the Bay of Biscay. The base wine was aged for one year on lees, with a third of it aging in barrel, it then spent 18 months undergoing a traditional sparkling fermention in bottle. Sparkling Txakolina! Not just fizzy, sparkling! It is everything that you imagine it would be! Bring on the oysters! he Getaria project of the Artadi family of wineries, Izar-Leku was originally intended to be a Txakoli winery, but with experimentation and some guidance from their friend Rapha Bereche, the sparkling project was created. A full Champagne-method production, Izar-Leku is incredibly fresh, a beautiful Champenois autolytic character lending a new viewpoint to the famous wines of the region.
