Abstract: A beverage brewing system is adapted to have a brewing configuration, in which, a brewing chamber has a brewing substance therein, a bottle initially has a fluid therein, a lid is located over a cup, the bottle is removably attached to the lid and located over the lid, the brewing chamber is located between the bottle and the cup, and a blow-out valve is located between the bottle and the brewing chamber so that the blow-out valve initially hinders a flow of the fluid from the bottle to the brewing chamber. The blow-out valve is adapted to be breached at a predetermined pressure when the fluid is heated to allow the fluid to pass through the brewing chamber into the cup to form a brewed fluid. The entire system is preferably disposable and microwavable. Preferably, the system has a compact storage configuration and a portable drinking configuration as well.
