Sektkellerei Karl Infuehr has stood for tradition and excellence in Austrian sparkling wine production for over 100 years and is considered the most award-winning sparkling wine producer in the country. With a deep understanding of quality and craftsmanship, the company produces its exquisite sparkling wines using the renowned Charmat method. This method, named after its inventor Eugene Charmat, enables fermentation in pressure-resistant tanks, giving the sparkling wine a fine bubble and uniform quality.

PetNat, short for Petillant Naturel or Rural Method, is an old and traditional way of producing sparkling wine. In this method, the must is refined into sparkling wine in just one fermentation. During this fermentation, the yeast transforms the existing sugar into carbon dioxide and alcohol. In the controlled Charmat method, the carbon dioxide cannot escape and is elegantly incorporated into the wine.

"PetNat" is characterized by its ability to build up controlled pressure. It is freed from turbidity through filtration and has a clear taste. As a result, there are no unpleasant surprises with this sparkling wine in terms of taste, appearance or explosive opening of the bottle.
