Sahti

Sahti is a Finnish type of farmhouse ale made from malted and unmalted grains including barley and rye. Traditionally the beer is flavored with juniper in addition to, or instead of, hops; the mash is filtered through juniper twigs into a trough-shaped tun, called a kuurna in Finnish. Sahti is top-fermented and many have a banana flavor due to isoamyl acetate from the use of baking yeast, although ale yeast may also be used in fermenting. The end product is a cloudy beer with phenolic flavors and a distinct taste similar to banana, balanced by the bitterness from the juniper branches. The carbonation level tends to be very low. Sahti was traditionally brewed as a farmhouse ale, but commercial versions are now available. Commercial sahti is usually 8% 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. Within Finland, sahti has differing characteristics depending on which part of the country it is from. It is often known as Tavastian beer from Häme but it is also made in Finland Proper and some parts of Central Finland. Every year the Finnish sahti brewing championship is held on the first weekend in August.
