I thought it was Juniper Berries that give gin it’s unique taste; though there are lots of recipes for cocktails that add coriander/cilantro. I don’t know - I’m not a spirit drinker, and don’t know much about them.
You just solved a mystery for me:-). I work as a waitress and occasionally fill in as bartender, funny as I just started having wine with dinner at age 40. Prior to that I didn’t drink. Occasionally people order a beefeater martini-I had no idea what they meant. I envisioned a beef stick instead of olives, I just knew that we didn’t serve them.
Now I know!
