When fed a few coins the machine in Kingham fills and then dispenses a glass bottle with a screw top, containing cold, thick, luscious liquid residents say reminds them of what milk used to look and taste like.
The machine belongs to Adam and Caroline Fleming, who run the nearby Nell's Dairy and who fill it up with fresh milk every two days, The Daily Telegraph reported.
"We spotted one on holiday in Italy two years ago," Caroline said. "We were sitting in a village square near Pisa, and there was this milk-vending machine outside a shop.
"People were filling up jugs and bottles even though the shop was shut. We thought it could be a great opportunity to sell our milk directly to the public without selling it through the horrible supermarkets. Oh, I'd better not say that."
The Flemings said the refrigerated vending machines -- they've just installed a second in town -- means they can sell their milk to locals at any time of day or night, long after the local supermarket has closed for the evening.
