text: Fermented water contains a similar alcoholic content of wines as both beverages are fermented on yeast, however fermented water differs from wine and other fermented beverages in that it contains no fruit juice or residual sugar after manufacture.
  Kilju can be produced by fermenting sugar, yeast, and water, but it was illegal in Finland before March 2018; therefore, grain, potatoes, fruits or berries were used during fermentation to avoid legal problems and to flavor the drink. Oranges and lemons are a popular choice for this purpose.
