Hosts can bring an otherworldly glow to their Halloween festivities with AGWA de Bolivia, literally “Water from Bolivia,” touted as the world’s original coca leaf liqueur.

It’s a truly international blend. Choice coca leaves are plucked high in the Andes and shipped to Amsterdam where Dutch artisans quickly macerate the leaves into tea and blend with Chinese green tea, ginseng, Amazon guarana and African mint for a 60-proof herbal liqueur that is a striking bright green in color.

(MSRP: $31.99 for 750 ml)

When frozen for four hours, AGWA forms ice crystals, which concentrates the color and transforms the liquid into a green glow you would be proud to serve to Martians. Fiendishly clever!

Here’s a recipe for your Halloween sipping pleasure.
