Copenhagen has long been associated with beer. Carlsberg beer has been brewed at the brewery's premises on the border between the Vesterbro and Valby districts since 1847 and has long been almost synonymous with Danish beer production. However, recent years have seen an explosive growth in the number of microbreweries so that Denmark today has more than 100 breweries, many of which are located in Copenhagen. Some like ''Nørrebro Bryghus'' also act as brewpubs where it is also possible to eat on the premises.
