You can always make your own, some neighbours across the road do it every year, a truck load of grapes arrive at the end of summer and disappear into the garage. A month or two later short swarthy looking gentlemen arrive in ones and twos carrying large brief cases and dressed in dark suits. They must be fairly well off because they all seem to own biggish automobiles and invariably have a driver who opens the door for them.
It must be some sort of party they have every year and the guests get to go home with a bottle of home made wine made from Sicilian grapes.
