How to Store Brewed Coffee

The only way to store brewed coffee is in an air pot (vacuum thermos with a pump). The air pot should be "primed", that is, preheated with boiling water, or pre-cooled with ice or in a freezer. If you are pre-cooling an air pot in a freezer, make certain to leave the top open. As soon as the coffee has been brewed, it should be immediately put into the air pot. Never allow coffee to sit in an open container on a warming plate. Brewed coffee is losing volatiles to the atmosphere at a tremendous rate, and will begin to significantly lose flavor within minutes.
