Is there coffee in a coollata?

A "coollata" is not a standard drink with a known recipe. There's no common beverage with that name that I'm aware of.

It's possible it's a regional name for a drink or a misspelling of something else. Could you provide more context?

* Where did you hear this word?

* What kind of drink were you thinking of?

* Was there a specific ingredient list or description?

With more information, I can help you figure out if coffee is a part of it!
