AFAIK Guaraná Antártica doesn't have much caffeine at all, that's one of the reasons I like it more (can drink it at night). It might not even have caffeine at all, although I can't find that information anywhere.

I would think that must mean it doesn't contain much Guaraná either, since it has twice as much caffeine as coffee[1]?

That's actually certainly possible, most of it is probably water and sugar lol. Although I haven't managed to actually find the amount of caffeine online, when I get another one I'll see if that information is available in the drink.

Anecdotal [0]: The federal government has attempted in the 40s to require that Guaraná sodas had at least 0.5% of it's contents in Guaraná seeds, however even that was already too much caffeine so it didn't happen!

edit: Found a source for this, Guarana Antarticá has around 1/10 of the caffeine in Coca-Cola [1].

Several sites I found list Guaraná Antarctica as having 30 mg of caffeine vs Coke's 34 mg [0]. It is also similar in sugar content contrary to what I initially found.

That doesn't match with my personal experience comparing the effects of Guaraná Antarctica and other sodas (eg Coke). Also, websites in Portuguese [1] claim that Guaraná contains only 2-4 mg of caffeine per 350ml. I wasn't able to find an official source.
