Sima is a Finnish fermented low-alcohol drink and soft drink. It is traditionally a form of mead, an alcoholic beverage produced by fermenting a solution of honey and water, although in modern times the honey is generally replaced with different kinds of sugar, mostly syrup, which makes it a sugar wine. The drink also has a very low alcohol content due to limited fermentation. Sima is therefore a sweet sparkling beverage that is mainly seasonal and connected with the Finnish Vappu festival. It is usually spiced by adding both the flesh and rind of a lemon.
Sima is usually accompanied by a (donut), a (a special Vappu funnel cake), or a (rosette).
The Finnish word is an old name for honey, which Elias Lönnrot used to mean a drink in his epic poetry, the Kalevala.
History
Mead was originally brought to Finland in the 1500s from Lübeck and Riga.
