Austrian Sparkling Wine Day, also known as Austrian Sekt Day, is observed in Austria every October 22. This holiday was established by Austrian sparkling wine producers to promote their products both nationally and internationally. The celebration highlights the quality and diversity of Austrian sparkling wines, particularly those made using the traditional method, which is distinct from the Charmat method commonly used for German Sekt. The origins of Austrian Sekt date back to the Austro-Hungarian Empire, with Robert Alwin Schlumberger being the first producer in Austria, introducing his sparkling wine in 1846. On this day, wineries across Austria open their doors to visitors, offering tastings, cellar tours, and Sekt and food pairing classes. The most common grape varieties used in Austrian Sekt include Grüner Veltliner and Welschriesling, with Blaufränkisch used for sparkling rosé wines. Celebrants are encouraged to share a bottle of Austrian Sekt with friends and promote the holiday on social media.
