My christmas brew is a Courage Russian Imperial Stout clone. I have one bottle every christmas eve (the whole batch is at my parents' house so I can't break into them at other times). The recipe was pretty simple pale/amber/black (touch of brown) with some dark candi syrup and cane sugar (OG 1.101), 50 IBUs of Target, fermented with 1028 in primary, then aged on oak cubes with some Brett A.
Not sure if that is exactly what you were looking for, but it says winter time to me.
