- "Isn't that hot?"
- —Jack O'Neill
Coffee is a hot drink known to have been consumed on Earth. The personnel of both Stargate Command and Atlantis expedition widely use coffee, particularly Dr. Rodney McKay, who is known at some point to drink 11 cups of coffee a day, which shows a possible addiction. (SGA: "Underground")
Whilst under the influence of Urgo, who was curious about Earth, SG-1 became more inclined to drink coffee, thinking it has been given a hint of cinnamon. At that point Teal'c picked up a pot and drank half a gallon of steaming hot coffee. (SG1: "Urgo")
Unfortunately, during the evacuation of Icarus Base to Destiny, coffee was not part of the supplies brought through the Stargate. As a result, some members of the Destiny expedition began experiencing symptoms of caffeine withdrawal. (SGU: "Darkness")
