Since making the full transition to 100% organic certification in 2021, the Luftburg has set new standards in the Austrian restaurant industry. What began as a bold vision back then is now an international flagship project for sustainable dining—and we celebrated it in style.

A celebration for partners, friends, and the future

In glorious spring weather, long-time companions, partners, and organic suppliers gathered to toast five extraordinary years together. Among the guests were: District Mayor Alexander Nikolai, CEO of the Austrian National Tourist Office Astrid Steharnig-Staudinger, Sales Director of Brau Union Bernhard Mitteröcker, ÖOC President Horst Nussbaumer, CEO of the Schönbrunn Group Klaus Panholzer, Head of the Tourism Section Ulrike Rauch-Keschmann, and soccer legend Toni Polster.

Guests enjoyed the best that Luftburg’s kitchen has to offer: from the legendary crispy grilled Sur ham hock to innovative vegetarian creations—all guaranteed to be organic.

"Success is a team effort"

In an emotional speech, Bianca and Paul Kolarik thanked everyone who has walked this path with them—their family, their loyal suppliers, and their partners. “The fact that we are standing here today celebrating our 5th anniversary as the world’s largest organic restaurant is thanks to our companions, partners, and suppliers. They are the backbone of our philosophy. For us, ‘organic’ is not just a marketing buzzword, but a deeply rooted conviction for a future worth living.” – Paul Kolarik

The future remains green

For us, this anniversary is not an endpoint, but a milestone. Luftburg will continue to demonstrate that scale, quality, and environmental responsibility can be perfectly combined—as a gathering place for all generations who appreciate mindful enjoyment without compromising on taste.
