Bott Geyl Cremant Crémant d'Alsace is the appellation for the white and rose sparkling wines of the Alsace wine region of northeastern France. Introduced in August 1976, the appellation now accounts for approximately one quarter of the region's output – about 45 million bottles per year, up from 31 million in 2009. Apart from Champagne (150 miles/240km to the west), it is the dominant French sparkling wine appellation, with more than half the output of all Crémant wines. Co-operatives are the big-volume players, with Wolfberger alone responsible for 6 to 7 million bottles. But many of the regions most prestigious estates make sparkling wines.
