Pepsi Max is a diet cola marketed at men rather than women.

Pepsi Max, in the UK at any rate, is the cola to beat all others. Okay, cola is basically water, sugar, cola extract and caffeine. Pepsi Max strips this right back to water, caffiene and a bit of brown colouring. In this elegant simplicity it manages to carry more taste and body than any other cola (including bizarrely Diet Pepsi). YMMV, of course, as I'm think recipes are varied from place to place. In Peru, I found it unbearably sweet.
