Cryoconcentrating Cider

I decided to try making ice cider this year. Ice cider is a sweet apple wine made from concentrated apple cider that allows more alcohol production than normal cider, along with residual sweetness after fermentation. Normal cider is about 10% sugar, and this has to be concentrated to at least 30% sugar to make ice cider. The defining feature of ice cider is that it is concentrated by partial freezing, causing ice crystals to form, and the sugars are forced into the remaining unfrozen portion.
