Apparently it's taking off in the UK this summer: a number of retailers are stocking 25cl cans of whites or roses for about GBP2.50. The marketing pitch is they are ideal for summer picnics, Wimbledon and the like, easy to transport, keep cold and (crucially!) open.
I'll be in London end of June for a couple of days and may have to investigate.
Never seen that before. I would imagine the cans would have to be lined somehow. Wine stored in metal just doesn’t sound right.
I haven't noticed it in the supermarkets here, but I'm in the provinces so it might not have made it yet...
