More bizarrely, and deeply disappointingly, it appears (at least in the US) to contain neither cider nor condensed milk, the ingredients being "Carbonated water, glucose, sugar, artificial flavor, citric acid" according to http://www.asianfoodgrocer.com/browseproducts/Mitsuya-White-Cider.HTML. I think this is clearly a case to take to Trading Standards (should you find it in the UK). Well maybe taste it first, just in case.
