The mojito's most attractive trait is also the reason why it is so wonderful for hot weather: it is extremely refreshing. The combination of mint, lime, rum and club soda is light, effervescent and mildly citrusy. It is also lower in calories than a margarita, which may not matter to everyone, but for girls who will be drinking it in a bikini, this is a plus. My favorite thing about a mojito is that after you have one (or four) you don't have the unfortunate lingering heartburn or sugar-induced headache. When drinking outdoors, it is important to stay hydrated and in my rationalization, any drink that includes added water helps with this. (I know this is completely ridiculous, but it's my rationalizations that keep me warm at night, so don't take them away from me).
