Germany loves to drink Glühwein (warm wine) in Winter, where else in the world do they practice that? In Germany it is a tradition to drink warm wine in Winter called Glühwein, especially during the weeks before Christmas.

Are there other countries with comparable warm wine drink traditions for winter?
