Beer

"I find it a refreshing substitute for... food."

- Jack O'Neill

Beer is an alcoholic drink widely used on Earth. Members of SG-1 and the Atlantis Expedition drink beer mainly for celebratory reasons. Teal'c on the otherhand, doesn't drink beer or any other forms of alcohol, as it could have adverse effects for his symbiote.

Col. Jack O'Neill used beer as a "secret ingredient" for his barbeques, as he pours beer onto the grill with his steaks and other forms of meat. He also, at one point switched brands. In 2000, he was drinking Budweiser, and later switched to Guinness in 2004.
