Eisberg Signature Sparkling Blanc is the sparkling white in Eisberg's Signature sub-range, produced by Schloss Wachenheim in Trier, Germany. Schloss Wachenheim has been making alcohol-free wine since the 1980s, establishing a production history in dealcoholised wine that predates the current wave of mainstream AF interest by several decades. The Signature line sits within a wider Eisberg portfolio that includes the Be Free and Selection tiers, covering still and sparkling styles.
