St. Georgen-Bräu is a historic brewery located in Buttenheim, a small village in the Franconia region of southeastern Germany. According to historical sources, the brewery was founded in 1624 by Georg Modschiedler, making it one of the oldest brewing establishments in the region. It operates under the name Gg. Modschiedler OHG and is situated at Marktstraße 12 in Buttenheim. It is noted as the largest of three breweries in the village, a remarkable fact that speaks to Buttenheim's deep-rooted brewing culture. St. Georgen-Bräu is best known for its Kellerbier, a traditional unfiltered, amber-coloured lager that is matured in cellars according to time-honoured Franconian brewing methods. The brewery's identity is closely tied to this style, and its website is fittingly found at kellerbier.de. Beyond Kellerbier, the portfolio includes a Märzen at 5.6% ABV, a finely herbed Pilsner, an alcohol-free option, and seasonal specialities such as a Heller Bock. The range is primarily aimed at the local and regional market, staying true to Franconian brewing traditions. The brewery's Kellerbier has gained recognition beyond German borders and is available through specialist beer importers in the Netherlands and Belgium. Its reputation rests on authenticity and craft, producing beers that reflect centuries of Franconian brewing heritage in an unpretentious village setting.
