Champagne. It tastes of bitter, sour and fizz and because of its stupidly intense carbonation, drinking it needs to be done in tiny little wincing sips, lest it bubble up through your sinuses and come out of your nose.

I swear people only pretend to like champage because they believe it's the drink for 'classy' celebrations, so disliking champagne is, in their mind, a 'low class' and ungrateful thing to do.
