a pitcher having an interior volume;
a brew basket for receiving brewing ingredients, the brew basket comprising a mesh structure and being positioned in the interior volume of the pitcher; and,
an agitator positioned within and rotatable relative to the brew basket, the agitator operatively coupled to a plurality of agitator magnets;
wherein the plurality of agitator magnets are coupled to the plurality of base magnets, such that rotation of the plurality of base magnets by the motor operates to rotate the plurality of agitator magnets and the agitator.
9 . The liquid brewing device of claim 8 , further comprising a cap removably connected to a lower end of the brew basket.
10 . The liquid brewing device of claim 9 , wherein when the brew basket is inserted in the interior volume of the pitcher, the cap is in contact with a lower surface of the pitcher.
11 . The liquid brewing device of claim 8 , wherein the base comprises an upper surface configured to receive a lower surface of the pitcher.
12 . The liquid brewing device of claim 8 , wherein the pitcher comprises an outlet for pouring liquid from the interior volume, the outlet being positioned outside the brew basket, such that brewing ingredients remain in the brew basket when liquid is poured from the interior volume through the outlet.
13 . The liquid brewing device of claim 8 , wherein the plurality of base magnets comprise at least one base magnet having a first polarity orientation and at least one base magnet having a second polarity orientation opposite the first polarity orientation, and wherein the plurality of agitator magnets comprise at least one agitator magnet having the first polarity orientation and at least one agitator magnet having the second polarity orientation.
14 . The liquid brewing device of claim 8 , wherein the agitator and the plurality of agitator magnets are positioned entirely within the brew basket.
15 . A method for liquid brewing comprising:
inserting brewing ingredients into a brew basket having an agitator located in a lower portion of the brew basket, the agitator operatively connected to at least one agitator magnet positioned in the brew basket;
inserting the brew basket into a pitcher;
adding a liquid to the pitcher;
placing the pitcher on a surface of a powered base having a motor and at least on base magnet rotatable by the motor relative to the base; and,
supplying a predetermined first level of power to the motor for a predetermined first period of time to rotate the at least one base magnet in the powered base, and the at least one agitator magnet and the agitator in the brew basket.
16 . The method of claim 15 , further comprising subsequently supplying a predetermined second level of power to the motor for a predetermined second period of time, wherein the predetermined second level of power is less than the predetermined first level of power, and wherein the predetermined second period of time is greater than the predetermined first amount of time.
17 . The method of claim 16 , further comprising subsequently supplying a predetermined third level of power to the motor for a predetermined third period of time, wherein the predetermined third level of power is less than the predetermined first level of power and greater than the predetermined second level of power, and wherein the predetermined third period of time is less than the predetermined second period of time.
18 . The method of claim 17 , further comprising subsequently supplying a predetermined fourth level of power to the motor for a predetermined fourth period of time, wherein the predetermined fourth level of power is less than the predetermined third level of power, and wherein the predetermined fourth period of time is greater than the predetermined first period of time.
19 . The method of claim 18 , further comprising subsequently supplying a predetermined fifth level of power to the motor for a predetermined fifth period of time, wherein the predetermined fifth level of power is less than the predetermined third level of power, and wherein the predetermined fifth period of time is greater than the predetermined first predetermined of time.
