Mimzag - מִמְזָג

Most people, including Israelis, probably don't know there is an official Hebrew word for the term "cocktail".

Well, that's what we're here for, there is a word and it is mimzag. If you sit at a bar and ask for a mimzag, the bartender most likely will have no clue what you're talking about, and that will be your opportunity to teach him/her a new word in Hebrew!
