During Rotkäppchen’s dealcoholisation process, the alcohol contained in the wine is gently removed using a method that is unique throughout Europe. But no matter what method is used, the finished product always contains a certain amount of residual alcohol. For a drink to be labelled ‘alcohol-free’, it may not contain more than 0.5% alcohol. In a regular glass of sparkling wine (0.1 l) that is equivalent to half a millilitre of alcohol. In comparison, a normal bottle of beer (0.5 l) contains 25 ml of alcohol on average.
Interestingly, the alcohol level in many fruit juices, particularly grape juice, is similar to the level in alcohol-free sparkling wine. After ripening for ten days, even bananas contain up to 0.6% alcohol.
