Beverages labelled brännvin or viina are usually unflavored and have an alcohol content between 30% and 38% ABV. European Union regulations reserve the name "vodka" for beverages distilled to at least 95% ABV and bottled at 37.5% or higher. In Finland, the word viina is always used for Finnish-made neutral spirit, including Finnish vodka, and the Russian word (vodka) is used only for vodkas from other countries. In informal speech, viina can also refer to any similarly strong beverage similarly to booze, whether flavored or unflavored.
The term "vodka" was not used for Swedish vodkas before 1958.
