Coffee

Coffee is a hot drink known to have been consumed on Earth, the personel of both the SGC and Atlantis expedition widely use coffee, particularly Dr. McKay, who is known at some point to drink 11 cups of coffee a day.

Whilst under the influence of Urgo, who was curious about Earth, SG-1 became more attached to coffee, thinking it has been given a hint of cinnamon. At that point Teal'c picked up a pot and drunk half a gallon of "steaming hot" coffee in one go.
