Taken from wikipedia:-
Wine gums contain no wine. The name comes from the lingering, subtle fruit flavours that make it "similar to the experience of savouring a fine wine". In reference to this, the sweets have the names of alcoholic drinks on them, for example port, sherry, champagne, claret and Burgundy. Also appearing on the gums are "M" and Maynards. For those in the United States of America, they most closely resemble Jujyfruits in colours, texture, and sweetness, though with different flavours. According to Cadbury Schweppes[2], red and black are the most popular colours. Red is traditionally tart cherry-flavoured whereas the black is liquorice (anise).
My favourite is red.
