There are so many wonderful cocktails containing Chartreuse, both green and yellow, and I've added this one to my list. I've yet to find one I don't like. This cocktail is excellent but, despite being now near 75 years old, had escaped my scrutiny. I love that Diffords resurrects these excellent classic cocktails and makes them accessible. Cocktail history seems to add to the pleasure of sipping on these old drinks, and I appreciate this addition.
