Brouwerij Martinus is a family-owned microbrewery located in the heart of Groningen, the Netherlands. The brewery is housed in a historic building in the Binnenstad-Zuid district, where entrepreneur Albert-Jan Swierstra ran a printing company for twenty years before deciding to chart a new course and transform the space into a craft brewery. The name and identity of the brewery are also connected to Marten Visser, whose passion for beer and background in graphic design shaped the visual character of the brand. Brouwerij Martinus brews artisanal beers with a focus on flavour and local identity. Their portfolio includes styles such as an IPA and a Dubbel, reflecting both hop-forward and malt-driven traditions. Rather than competing with the trendy craft beer scene in cities like Amsterdam, the brewery has consciously chosen its own path, staying true to quality and character rooted in Groningen. With a 4.5 rating on Tripadvisor and over a hundred reviews, Brouwerij Martinus is recognised as one of the finest brewery experiences in the Netherlands. Visitors describe it as a cosy and welcoming spot that offers genuine insight into the craft of brewing. The taproom in the city centre makes it a must-visit destination for beer lovers exploring Groningen.
