The brewing system disclosed herein includes a spinning or rotating inlet nozzle for use in intermixing hot water and coffee in a coffee cartridge. The inlet nozzle may include one or more flow ports that inject hot water into an inner chamber of the coffee cartridge at select angles, locations and pressures to create the desired fluidized mixture of hot water and beverage medium. Such an inlet nozzle may be adapted for use in commercial coffee brewers and the amount of coffee brewed may be user regulated with an external indicator dial coupled to a controller regulated rheostat that governs fluid flow to the brewer head by taking readings from a pump, flow meter or strain gauge.
