Sahti

Sahti is a traditional beer from Finland 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 flavored with juniper berries in addition to, or instead of, hops; the mash is filtered through juniper twigs through a trough-shaped tun called a kuurna in Finnish. Sahti has a distinct banana flavor due to the production of isoamyl acetate by the yeast. Sahti is a top-fermented brew (ale), and while baking yeast has been used traditionally, ale yeast may also be used in fermenting.

The end product is a cloudy beer with yeasty and phenolic flavors and a distinct taste similar to banana. Sahti is traditionally homebrewed but in recent years commercial versions have become available. Commercial Sahti usually has around eight percent ABV. In Finland, due to the higher percentage of alcohol in sahti, it is only sold in commercial sahti breweries, pubs or state-owned Alko stores, not in regular markets or grocery stores. Sahti has to be stored cold until consumption and is therefore not available in all Alko branches.
