The only modern carbonated drink (or as Americans call them, "Soda") that I'll consider drinking is something similar to Red Bull or BAWLS, and the latter is very hard to get in Australia. Please, no crude jokes, because BAWLS is an actual drink and is favoured for its energy content.
Even so, I prefer the following to any "modern" drink:
Ceylon or Green Tea, and Coffee. Proper tea and coffee, instant coffee makes me retch, and badly or hastily prepared tea tastes either bitter (due to the leaves being "cooked" by overly hot water) or far too weak.
I don't like anything alcoholic, but occasionally I'll have some wine depending on the occasion and how decent the wine is. Other alcoholic drinks just taste horrible to me.
