Picking for the first Federweißer (a partially-fermented, yeasty grape speciality) had already begun in August, with the main harvest following two weeks later and thus earlier than ever before.

Grape juice can only be called burčák for two to three days, when the sugar and alcohol is approximately balanced.

Is a fermented wine juice in the phase of “furious” fermentation, during which sugar, i.e. glucose, is broken down into alcohol and carbon dioxide.

The importance of this beverage is defined in the Vintner and Winemaking Act, which precisely specifies when burčák may be offered for direct consumption.
