Stjørdalsøl is a traditional beer style that falls in the broad category of Norwegian farmhouse ales. It hails from Stjørdal, Trøndelag, one of Norwegian regions that has preserved the tradition of brewing these old farmhouse brews.
Stjørdal now has the largest number of traditional breweries and even features several commercially produced examples. This regional style is very versatile. The final brew varies among breweries and brewers, but most are amber-colored and have a distinctive malty character and smoky notes, ranging from delicate to heavily smoked.
