Reminds me of "Drink without a name". I'm sure I'll love it. Will use the Élixir Végétal instead of standard green chartreuse, cause it adds something I can't put my finger on.
I usually use a dropper. I squeeze to take in, and then give a good hard squeeze out, instead of a drop. Feels more akin to a dash of Angostura, rather than a Japanese bottle. Perhaps half bar spoon or whatnot. But do as you please :)
