Abstract
A beverage making machine may include a cartridge holder to hold a cartridge used to form a beverage. The cartridge holder may include a lower portion arranged to receive and hold the cartridge and a movable upper portion arranged to clamp the cartridge in place. The cartridge holder may be arranged to hold upper and lower compartments of the cartridge in spaces having a different pressure, e.g., an upper compartment of the cartridge may be held under relatively high pressure, and a lower compartment may be held in a space at ambient pressure. The cartridge holder may pierce upper and/or lower compartments of the cartridge to introduce activating fluid and/or receive carbonating gas from the upper compartment, and/or to introduced pressurized air into the lower compartment to force beverage medium to exit.
