Flensburger Brauerei

What Flensburger Brauerei does

Flensburger Brauerei Emil Petersen GmbH & Co. KG is a privately held German family brewery founded on 6 September 1888 and headquartered at Munketoft 12 in Flensburg — the northernmost large brewery in Germany. The company operates under a German Kommanditgesellschaft structure with the Dethleffsen-Petersen family retaining majority on the advisory board and professional managers (Jörn Schumann and Michael Seip) running operations since 2010. Flensburger brews and sells a full portfolio of beers under the FLENS brand following the Reinheitsgebot (German Beer Purity Law), using proprietary technologies including the Merlin wort cooking system, in-house cultivated pure-culture yeast, the Flensburger Gletscherquelle glacier spring water source, and a proprietary coastal barley variety called Küstengerste. The brewery operates the world's largest swing-top (Bügelverschluss) bottling facility, with the iconic 'plop' opening sound functioning as a registered brand symbol since 1888.

The product portfolio spans classic beers (Flensburger Pilsener, Edles Helles, Gold, Dunkel, Strand-Lager, Radler, Kellerbier, seasonal Bock variants), a non-alcoholic line (Flensburger Frei produced via vacuum rectification, Strand-Lager 0.0%, Radler Frei, Malz, Wasser), specialty products including the cult Bölkstoff beer and 2-liter Mega-Plop bottles, spirits (FLENS Bierbrand and FLENS Whisky), and the newly launched Flensburger Küstenlimos soft drinks (2025). Flensburger generates revenue through retail distribution across German supermarkets and convenience stores, on-trade/hospitality via 20L/30L/50L kegs, an international export sales team, and direct-to-consumer e-commerce via the Plop-Shop (shop.flens.de) and bierselect.de. The company also operates brewery tours, the FLENS Festival, the FLENS CUP sporting event, the FLENS StrandGut coastal-cleanup initiative (now in its 10th edition), the 'FLENS verstehen' content hub, and the FLENS Miniserie video series to drive brand engagement. Cumulative investment over the past decade exceeds €50 million, and the brewery surpassed 600,000 hectoliters of domestic production in 2018 — its highest output since the early 1990s.
