Zeronimo Fancy Red Wine Tonic is an alcohol-free wine tonic in the Zeronic sub-range, part of an Austrian brand that spans both still dealcoholised wines and sparkling wine tonic formats. The base is a dealcoholised Zweigelt sourced from Heribert Bayer in Burgenland, with carbonation and a bitterness contribution from quassia wood extract rather than the quinine more common in tonic formats. Zeronimo uses vacuum distillation with a patented aroma recovery step, designed to retain volatile compounds that conventional dealcoholisation strips out.
