I would probably choose the Ketel One original vodka, as I feel it would be the most versatile in an environment where I wouldn't have much background on what else I might encounter to serve/mix along with it, and, if in a pinch, it may be the most appropriate for non drinking medicinal applications as well, keeping that whole survival thing in mind.
What are the top trends you are seeing in drinks right now?
Love it or hate it... Aroma and/or flavor bubbles floated onto the tops of cocktails seems to be picking up quite a bit of steam.. Outside of that specifically, anything hyper visual, interactive, or intimately engaging seems to be the mode du jour, with the goal being to infuse a visit to the bar with a unique, memorable experience.
