If you haven’t already heard of Beber and Tomar, they are used when talking about drinking in Spanish. The general answer is, they are both correct. However, some parts of the Spanish speaking world will have their own way of using these two verbs.
From my personal experience, beber is used with soft drinks and tomar is used for alcoholic drinks. I have seen this question asked a lot and there really is no correct answer. Some Spanish speaking countries very rarely ever use beber and use tomar; although this may be different in other cultures.
So honestly, it’s a matter of culture and also a matter of preference. This Verb War is nothing to worry about!
