Sahti is the only primitive beer to survive in Western Europe. The beer that peasants learned to brew in the 1500s is still made much the same way today, much of it in people's homes. Many sahti brewers of today use woodfire-heated kettles from their cow houses and saunas as mash tuns. Fresh juniper twigs are used in the filter bed on the bottom of the lauter tun and also infused in the hot brewing water. It is a sweet, malty, turbid beer with complex flavor, the bananalike notes and phenolic peaks found in a German Weizen intermingling with juniper. The alcohol content varies from 7 to 11 percent ABV.
