While in Peru we drank a lot of Inca Kola. Inca Kola is the national soft drink of Peru. It is so good with this almost bubble gum type flavor. An interesting history of Inca Kola can be found here.
I've been searching for where I can purchase Inca Kola here in the US. It is sold on Amazon.com and a few other online stores (I love this one) but I am hesitant to purchase a liquid soda to be shipped. I don't really know why. Maybe I'll give it a try. Maybe.
