An ancient Finnish farmhouse ale flavored with juniper and traditionally fermented with baker’s yeast. Typically 7.0–8.5% ABV, pale to copper, full-bodied and notably sweet, with very low bitterness. The hallmark is a strong fermentation character — banana, clove-like spice, and complex alcohols from the bread yeast — layered over a resinous juniper note from boughs and berries used in brewing.

Origin
Sahti is among the oldest surviving European beer traditions, a Finnish farmhouse ale still made much as it was centuries ago for weddings and other festive occasions. Two ingredients give it its identity: juniper, used both as a flavoring and as a natural filter bed, and bread yeast, which ferments the wort and contributes sahti’s characteristic banana-and-clove fruitiness. The wort is traditionally strained through a trough lined with juniper twigs and straw rather than boiled in the modern fashion, and only a small amount of hops, if any, is used.
For most of its history sahti was a home-brewed beverage made on Finnish farms rather than a commercial product. That changed in 1987, when Lammin Sahti in the village of Lammi became the first modern commercial sahti producer, helping bring the farmhouse style to a wider market while keeping its traditional methods. Sahti has since gained recognition as a distinctive part of Finland’s culinary heritage and holds European Union Traditional Speciality Guaranteed status, registered in 2002.
Notes
Sahti is a relative of other Nordic farmhouse ales, sharing its juniper character and bread-yeast fermentation with Sweden’s gotlandsdricke, though sahti is the stronger and sweeter of the two and lacks the smoked-malt note central to its Swedish cousin. Two things surprise first-time drinkers: how sweet and full it is despite the high alcohol, and how the banana-and-clove profile can resemble a German wheat beer even though the cause — baker’s yeast rather than a specialized weizen strain — is entirely different. Because it is unboiled, unfiltered, and often unpasteurized, traditional sahti is fragile and short-lived, meant to be drunk fresh and rarely traveling far from where it is made.
