Some years ago, archaeologists discovered the remains of a Scandinavian ale called Sahti inside a barrel in a Viking ship burial. Now modern brewers are trying out the ancient recipe.
Traditionally, Sahti was made by women brewers in Finland, although the recipe has spread throughout the region, with malted barley, malted rye, juniper boughs and hops, kiln-dried or smoked in saunas.
The modern recipe is "an all-grain batch of Pilsner Malt, Rye Malt, Crystal Malt, as well as a small amount of specialty grains previously smoked over pine and juniper boughs." The recipe and techniques for using it are available on the Discovery World website.
