Portable Brewing Device and Method of Making and Operating

A portable brewing device, comprising:

• a compressed gas container;
• a pressure regulator coupled to the compressed gas container and configured to control the pressure of gas released from the compressed gas container;
• a release switch communicating with pressure regulator and configured to release pressure controlled gas when actuated by a user;
• a water vessel configured to receive the pressure controlled gas when the switch is actuated by a user;
• a mixing vessel having a brew substance communicating with the water vessel and configured to receive water from the water vessel to pass through the brew substance when pressure is released from the gas container through the pressure regulator;
• and
• an outlet configured to release a brewed product produced from water flowing through the brew substance contained in the mixing vessel when brewing.

A portable espresso brewing device, comprising:

• a compressed gas container;
• a pressure regulator coupled to the compressed gas container and configured to control the pressure of gas released from the compressed gas container;
• a valve communicating with the pressure regulator that controls the flow of compressed gas into the water vessel.
• a secondary port in the valve that also serves as a vent for the water vessel when filled with boiling water to release the steam generated by the boiling water rather than pushing the water into the grounds vessel. This vent releases the excess pressure at the end of the brewing process to allow for a safe opening of the lid on top of the water vessel.
• a safety one way valve that prevents accidental release of compressed gas from the regulator towards the water vessel. The valve allows compressed gas flow only when the lid is completely pressed down.
• a water vessel communicating with the pressure regulator;
• a grounds vessel communicating with the water vessel and configured to receive water from the water vessel to brew espresso when pressure is released from the gas container through the pressure regulator;
• and
• an outlet configured to release espresso produced form water flowing through grounds contained in the grounds vessel when brewing.

• a secondary port in the valve that also serves as a vent for the water vessel when filled with boiling water to release the steam generated by the boiling water rather than pushing the water into the grounds vessel, where the secondary port releases the excess pressure at the end of the brewing process to allow for a safe opening of the lid on top of the water vessel;
• a safety one way valve that prevents accidental release of compressed gas from the regulator towards the water vessel, where the valve allows compressed gas flow only when the lid is completely pressed down;
• a water vessel configured to hold water and communicating with the pressure regulator;
• a grounds vessel configured to hold espresso grounds, communicating with the water vessel and configured to receive water from the water vessel to brew espresso when pressure is released from the gas container through the pressure regulator, transferring water from the water vessel and through the grounds;
• and
• an outlet configured to release espresso produced from water flowing through grounds contained in the grounds vessel when brewing.
