Carbonated, sweetened drinks are called soft drinks, pop, soda, or Coke* in the US. In Germany, the generic name for sweetened carbonated drinks is Limonade, or lemonade. Sigh. This one is a cola, marked as caffeine containing lemonade.
In my mind, lemonade is made of lemons or is meant to taste like lemons, is not carbonated, and is NOT cola.
*To me, this is the most ridiculous one in the bunch. In some southern states, people call all soft drinks "Coke." They'll say, "do you want a coke?" If the other person says yes, then the first person might say something like, "okay, do you want a Pepsi or a root beer?" Coke is Coke, folks.
