Chocolate drink with hardly any calories - ground cacao brewed like coffee

I know July/August is really no time to think about hot cocoa but I just tried Crio Bru Brewed Cacao. I suspect there may be other brands available but I read about this somewhere -- don't remember where.

It's cocoa beans roasted like coffee and ground. You brew it like coffee in a French press and it makes a tasty chocolate-tasting drink that only has 20 calories. I add a touch of soy milk so it's about 25 calories for a cupful. It's not much more expensive than ground coffee (cheaper than some) and certainly cheaper than a lot of other drinks. I ordered it on Amazon just a week ago and it arrived yesterday via USPS.

It's been lovely sipping cocoa this evening -- getting that chocolate feeling without many calories at all!
