I mostly enjoy whatever straight up, maybe with an ice cube. I am competent at mixing gin and tonic however. I get frisky at times and add some lime when I'm feeling celebratory. These complex "cocktails" look like some a PhD chemist would contrive in his spare time, to me. I see them as a way to hide the fact someone is using, um, less potable alcohol. Of course, I only recognize two basic kind of distilled alcohol, aged, and white.
I still really do not understand azeotropes, and I've tried.
