Fort Lapin Summer Sour is a refreshing sour ale from Brouwerij Fort Lapin, the artisanal brewery in Bruges that brews and bottles all its creations on-site. This beer is distinguished by the use of yoghurt bacteria, which converts a portion of the sugars into lactic acid, creating a pleasant sourness.

With a modest alcohol content of 4.7%, this is a thirst-quenching beer perfectly suited to warm weather. The combination of top fermentation and bottle refermentation gives the beer additional character and brightness.
