Advent calendars with stale pieces of chocolate behind each door are best left to the kiddos. For a hostess gift that adults will drool over (and will result in you being invited back again and again), this over-21-only alcoholic advent tracker is a sure bet. Behind each of the 24 doors lies a bottled dram of a different whisky - one of them is even a 50 year-old Scotch whisky! We�d understand, though, if you wanted to buy this for yourself.
