London cafe Bean & Wheat makes a charcoal latte made from grounded coconut shells.

The caffeine-free drink, called Black Heart Latte, is made with only charcoal, milk, and vanilla.

"The reason why we ended up going for the charcoal is simply due to detoxifying and purification," Assistant Manager and Head Barista Darren Cronin told Business Insider.

"Black Heart Latte is designed using organic coconut shells which have been ground and burnt, and then made into a charcoal. We utilize that with some vanilla essence and a good quality milk."

The cafe also makes other caffeine-free lattes, like the Matcha Latte and the Coconut Golden Turmeric Latte.
