Well I narrowed down the list of Tooks to those who start with I, but being quite unversed in tipples I have not been able to figure out the actual clue, so guessing the answer by a flip of a coin feels like cheating at this point. I may as well post the entire list for you to pick from. I've tried looking up various such drinks, but most of the names don't appear to be long enough or have the right letters. I'm just probably not looking for the right sort of tipples.
