Ice cider is more a sweet wine than a cider, with an intense apple flavour and sweetness, and acidity to balance the flavours. It originates from Canada, where specifications includes a pre-fermentation sugar content of not less than 30 °Brix, and a finished product with a residual sugar content of not less than 130 g/l, containing 7-13 % alcohol. This project aims to investigate and document some of the aspects of ice cider production process for Swedish conditions.
