Think advent calendars filled with candy are too kiddy? Well then, why not try filling them with booze instead? With the Whisky Advent Calendar, you get 24 shot-sized bottles each featuring a different sample of whisky. While the company won't tell precisely what is in the box ahead of time, they do give you one hint:
Behind one of the doors is a sample of 50 year old Scotch whisky, the full-sized bottle of which is worth £350!
They also have a Ginvent calendar for those who aren't too big on Scotch and bourbon.
