The ETTL Festbier originated from the summer festival of the brewery. For this occasion, brewmaster Florian Kosina created a golden shining festival beer for the first time, which was immediately well received by the guests. The enthusiastic response encouraged the brewery to enter this beer into the BeerTasting Community Award - and it was promptly awarded. To this day, the festival beer is not permanently part of the portfolio, but is exclusively brewed during the festival beer season.
