A box of joe, which typically contains coffee, can stay warm for about 1 to 2 hours if kept in a thermal carafe or insulated container. If it's in a standard cardboard box without insulation, the coffee may start to cool down significantly within 30 minutes to an hour. To maintain warmth longer, it's best to use preheated containers and keep the lid closed.
