Embodiments of the present disclosure relate generally to espresso makers that brew beverages without power. The machines are designed to work under manual power, delivering hot water to the brew portion of the machine from an integrated hot water source. The machines may be mounted on aircraft trolleys for seat-side coffee and/or espresso service.

A hollow cylinder (102) contains hot water for making a hot beverage, for example, coffee. The cylinder (102) has an inner wall (102a) extending along an axis (104) from an open upper end (102b) to an open lower end (102c) of the cylinder. A perforated closure (106) is releasably securable to the cylinder (102) to hold the coffee at the lower end (102c). A cap (110) carries a plunger (112) configured and arranged for sealing engagement with the inner wall (102a) of the cylinder (102). In use, the cap (110) is rotatable on the cylinder (102) about the axis (104) and is connected to the cylinder (102) by a helical formation. Rotation of the cap (110) on the cylinder (102) drives the plunger (112) towards the lower end (102c) of the cylinder (102) to press the hot water through the perforated closure (106) and the coffee held thereon and then into the vessel (118).

An extraction apparatus and methods for making and using the same are disclosed. The apparatus includes a cylindrical container with lid and pour spout, a container insert, and a plunger including a piston, a rod, a handle, and a filter or filtration chamber. The container insert is designed to catch infusible material which may be easily removed from the container when the container is empty or when the extract fluid remains in the container. The plunger may temporarily couple with the insert to allow the insert to be pulled up through the container with the grounds of other infusible material captured between the insert and the plunger allowing for quick and easy cleanup. The extraction apparatus is adapted for a use in a variety of sizes and may be adapted for manufactured at low cost. A variety of embodiments and alternatives are also included in the disclosure.
