Abstract: A single serve brewing system includes a water reservoir assembly, a pod retaining assembly and a strength adjustment assembly. The water reservoir assembly includes a concave member defining a predetermined volume, a first piercing member disposed on the concave member, a brew port formed on the concave member, and a water bypass opening formed on the concave member. The pod retaining assembly is pivotally coupled to the water reservoir assembly, and includes a housing defining an interior space, a pod support member, a second piercing member, a brewed beverage opening; and a dilution opening. The strength adjustment assembly includes a hollow tube disposed in the housing and having a first end adapted to extend through the water bypass opening and a second end coupled to the dilution opening to bypass the interior space. The strength adjustment assembly also includes a knob coupled to the hollow tube adapted to displace the hollow tube.
