Reading this thread has made me feel a bit common (I am). I've been so unadventurous when it comes to booze there are probably loads of drinks I'd like but have never tried.
Stella Artois is my lager of choice. I'll occasionally dabble with whiskey, though don't drink it often enough to have established a favourite. I've enjoyed some ales and "proper" beers when presented with them, but when left to my own devices I go back to my uninspired ways. Sometimes when I've got home and haven't had my fill I steal my dad's wine (cheap stuff generally). Used to hate red, but after having no alternative on a few occasions it was like a light switch got turned on and suddenly I liked it (that was a really strange experience).
I cannot drink cider as it was the first drink I got wasted on and it makes me ill. Similar case with straight vodka. I played a game in my teens where the objective was to chug as much as you could in one go. Not good!
Pro tip: Absinthe can lead to midnight fights in graveyards and loss of shoes.
