Sahti is a traditional beer from Finland.
Sahti is made from a variety of grains, malted and unmalted, including barley, rye, wheat, and oats; sometimes bread made from these grains is fermented instead of malt itself. Traditionally the beer is flavoured with juniper berries in addition to, or instead of, hops; the mash was filtered through juniper twigs through a tun called a kuurna in Finnish.
The end product is a cloudy, mildly alcoholic beer with yeasty and phenolic flavors. Sahti traditionally was a homebrewed beer; in recent years, commercial versions are available.
