Alcohol!!!!
now lets start with Whiskey,brandy, mead, cider, spiced rum, absinthe are amongst my favourites but any will do I even have a few combinations I have created myself including the green goblin ( absinthe and blue wicked) hobgoblin ( Absinthe, blue wicked, cider and another spirit) the green velvet (absinthe and guiness) possibly you can see a pattern
for non alcohol it would be drinking chocolate, or tea or good old H2O.
P.S. there is also the classic brew of Brandy, Methylated spirits, Pernod, Paint striper, Mr Sheen, Brake fluid, Drambuie. How am I alive...I might very well not be
