A hot toddy is a good winter drink, there are various recipes but the main thrust is whisky, honey, hot water and winter spices. Maybe some lemon and herbs.
Snowballs are popular for some reason, advocaat and sparkling lemonade. Probably no good if you don't like nog.
The white russian is probably a good move if you want something rich but don't like eggnog.
There are all kinds of punch suitable for winter, sloe gin (even if you don't like gin, sloe gin is a different beast) is a good move, other hedgerow fruits, cider and or a sweet, fruity red wine.
Mulled wine is always a good move for large groups.
It's pretty close to being a defining feature of the art. As it goes this example is actually rather restrained, no sashes, no flying ribbons, no scrolls...
