When my Swedish friend was still alive, we used to have Christmas at his parent's place every year. Despite the Australian heat, they would serve glögg. It was delicious, but I could not drink more than a glass unless the air cond was on at full blast. They would follow with a few shots of home brewed brännvin (Schnapps) which their relatives in Sweden would send them every year. The brännvin went surprisingly well with Gravlax and knäckebröd which they bought from IKEA.
But since this is Australia, we typically have beer, white wine, or rosé with Christmas. They MUST be chilled to just above freezing. Since I grew up in Western Australia, the wine of choice is a Semillon - Sauvignon Blanc which we call a "Classic Dry White" over here. It is really cheap but surprisingly fruity and dry.
I have tried many Belgian beers, notably Duvel and Chimay - but I think they are really heavy. They are almost like a complete meal in a bottle, it really fills you up.
