Eins Zwei Zero Zwei-Zero Sparkling Riesling is the sparkling Riesling in the Eins Zwei Zero range, launched by Leitz winery in 2016 as a dedicated alcohol-free line. The Riesling grapes are sourced from Rüdesheim, a specific provenance within the Rheingau that lends the drink its regional identity within the Zwei-Zero sparkling sub-range.
