I have a couple of Christmas ales left, I succumbed to the others over the past few weeks:-
8 Degrees' 'A Winter's Ale'
Delerium Tremens Christmas ale
Last night I tried Brewdog's 'There is no Santa' and was pretty amazed - totally not what I expected from a Brewdog offering... Probably the mildest and most desert-like of all the Christmas ales I've tried so far (Goose Island, Anchor etc).
