Beaten to the title of "The spirit of Christmas" I hope nobody is offended if we look at the other sort!
Although they both liked a good wine when friends came round, my mother also used to enjoy Advocaat on high days and holidays and the appearance of a bottle in the cupboard was a sign Christmas was on its way. My dad used to signal the arrival of Winter with a Whisky Mac (whisky +green ginger wine)
For me, Christmas means Baileys, I would never drink it at any other time of year, but also green ginger wine (Crabbie's) when I am writing the cards, and of course mulled wine especially with the mince pies.
What's yours?
