Brouwerij Kwartje is a Dutch contract brewery that was established in 2015. Based in or around The Hague, the brewery has been part of the local craft beer scene, collaborating with other regional breweries such as Brouwerij de Prael on community-oriented events in the city. As a contract brewery, Brouwerij Kwartje produces its beers using the facilities of established breweries rather than operating its own brewhouse. Beyond brewing, the brand has been associated with local markets where a variety of products, including beer, were sold alongside books, art and food.
