(Dailymail) - It's Europe's biggest warehouse and promises a very merry Christmas - if you like wine. Because between now and the big day an astonishing 11.5 million bottles of wine will be leaving this huge warehouse and wine packaging facility bound for supermarkets, off-licences and bars. The complex in Avonmouth, near Bristol, can store 9.5million gallons - enough to fill 15 Olympic-sized swimming pools.
