Cocoa Shell Tea from Undone Chocolate in the District. (Dixie D. Vereen/For The Washington Post)

SIP IT: Made from the husks of cocoa beans, cocoa shell tea from Undone Chocolate smells like brownies fresh from the oven yet tastes like a delicate chocolate-infused herbal tea. Adam Kavalier, who launched the company with his wife, Kristen, in December 2014, drew inspiration from the Peruvian tradition of making cocoa shell tea and found using the otherwise discarded husks a useful way to avoid waste in their bean-to-bar operation. (The husks, also called shells, are separated from the cacao nibs, which are ground to make chocolate bars.) A tea made from shells is more mild than one made from nibs, says Kavalier, and is rich in antioxidants and theobromine, a mild stimulant similar to caffeine.

We tried the tea brewed with warm water and, in the interest of summer sipping, we also cold-brewed a batch. Kavalier suggests using the cold-brew to make an old-fashioned with bitters. Chocolate bitters, of course.
