Historical Beer: Sahti

BJCP 27

Overall Impression
A sweet, heavy, strong traditional Finnish beer with a rye, juniper, and juniper berry flavor and a strong banana-clove yeast character.
Comments

The use of rye doesn’t mean that it should taste like caraway (a dominant flavor in rye bread). The use of juniper berries will give a flavor like gin (similarly flavored with juniper berries). The juniper acts a bit like hops in the balance and flavor, providing some counterpoint to the sweet malt.

History
An indigenous traditional style from Finland; a farmhouse tradition for at least 500 years, often brewed for festive occasions like summer weddings, and consumed within a week or two of brewing. A similar tradition exists in Estonia, where the beer is known as koduolu.
Ingredients
Malted barley along with malted and unmalted grains, often rye. Low hops. Juniper boughs used for lautering (traditionally in a hollowed-out log), but often producing a juniper/berry character. Often uses top-fermenting baker’s yeast in a fast, warm fermentation (German Weizen yeast is a good substitute). Not boiled; a long mash steep is used, with a separately added hop tea.
Commercial Examples
Now made year-round by several breweries in Finland.
