Chartreuse (US: /ʃɑːrˈtruːz, -ˈtruːs/ ⓘ, UK: /-ˈtrɜːz/, French: [ʃaʁtʁøz]) is a French herbal liqueur that has been made by Carthusian monks since 1737, reportedly according to instructions set out in a manuscript given to them by François Annibal d’Estrées in 1605.[1] It was named after the monks’ Grande Chartreuse monastery, located in the Chartreuse Mountains north of Grenoble, France. Today the liqueur is produced in their distillery in nearby Aiguenoire. It is composed of distilled alcohol aged with 130 herbs, plants and flowers, and sweetened, though the exact recipe is known only to select monks. The color chartreuse takes its name from the drink.



You’d want to tweak the ratios a bit for that — but yeah, I think it’s a great base for an enhanced gin rickey.
I’d probably aim for something like
with 6-10 oz of club soda, as a very loose starting point.–

I’d have to buy literally everything on the list but my family likes making cocktails when we’re together; this seems like a good one for that!
