Brewers use juniper branches twice over: as flavouring, and laid in the bottom of the mash tub as a filter bed, a technique shared with Finland's sahti. Gotland is where this farmhouse ale tradition survived best in Sweden.
Gotlandsdricka is an unfiltered, low-carbonation farmhouse ale brewed with smoked malt and flavored heavily with juniper — branches, berries and all. It's smoky, tart and rustic, closely related to Finland's sahti and traditionally served flat, almost like a cask ale.
