Where do these numbers come from?
From the USDA’s record “Hot chocolate / cocoa, NFS”, in the USDA Food and Nutrient Database for Dietary Studies (FNDDS). Caffeine varies with the beans or leaves, how it’s brewed and the shop, so a coffee-shop drink can have noticeably more or less than this. Check the brand’s own figures when you can.
