Alternative to the Orange Groove?

Alright friends. A few summers ago they had the Orange Groove. I can’t remember the exact recipe, but some kind of mocha with orange and specifically black agave sugar. I LOVED this drink. It tasted like a chocolate orange to me. My local stand would make it for me months after they discontinued it, but they eventually ran out of the black agave sugar. I haven’t had something similar since and I’m not sure how to order something similar! Any suggestions??
