Hot Drinks Are Defined as Tea and Coffee

Doctrine and Covenants 89:9 

9 And again, hot drinks are not for the body or belly.

President Brigham Young said:

“I have heard it argued that tea and coffee are not mentioned [in the Word of Wisdom]; that is very true; but what were the people in the habit of taking as hot drinks when that revelation was given? Tea and coffee. We were not in the habit of drinking water very hot, but tea and coffee—the beverages in common use.”
