Eisberg Signature Merlot is an alcohol-free red wine in the Eisberg Signature sub-range, made by Schloss Wachenheim in Trier, Germany. The alcohol is removed by vacuum distillation, a process that works at reduced pressure to lower the boiling point and protect the wine's aromatics. Schloss Wachenheim has been making alcohol-free wine since the 1980s, giving the Signature range a foundation built on long-established expertise rather than the newer wave of AF wine producers.
