Green Chartreuse is the kryptonite of many cocktail enthusiasts – it’s certainly mine. If you’re not familiar with Chartreuse, here is the crash course. It’s a French herbal liqueur that’s made by Carthusian monks based on a recipe they purportedly received in 1605. The two types that you’ll see most often are yellow (40% ABV) and green (55% ABV), but there are other iterations that include aged and higher ABV bottlings. Yellow is the more mild version, while green is the bolder.
