A cold brew coffee device may include a water reservoir containing water, a plurality of tubes for transporting water in the water reservoir to a different location, a drip mechanism for receiving water from the water reservoir, a coffee grounds container for receiving water from the drip mechanism, a pump for pumping water from the water reservoir to the drip mechanism, a container for collecting coffee-infused water from the coffee grounds container, a user interface for displaying information and providing alerts, a controller for controlling the pump and user interface, and a battery for providing power to the controller, the pump, and the user interface. ## Claims ### Claim 1 A method for preparing a cold brew coffee beverage comprising: receiving a coffee grounds container containing coffee grounds; receiving a preferred cold brew concentrate indication to prepare the cold brew coffee beverage; activating a pump to move water from a reservoir containing water to a drip mechanism, wherein the water passes through the pump; and receiving cold brew coffee in a container, wherein, the water passes through the pump at a rate based on the cold brew concentrate indication, wherein the rate is associated with a volume of water that passes through the pump, wherein the water passes through the drip mechanism to the coffee grounds container, and wherein the cold brew coffee beverage contents is received in the container after passing through the coffee grounds container. ### Claim 2 (depends on 1) The method of claim 1, wherein the pump is a peristaltic pump. ### Claim 3 (depends on 2) The method of claim 2, wherein the pump is a diaphragm pump. ### Claim 4 (depends on 1) The method of claim 1, further comprising determining a water level of the reservoir, and when the water level reaches a predetermined value, deactivating the pump and alerting the user. ### Claim 5 (depends on 3) The method of claim 3, further comprising filtering the water prior to moving the water from the reservoir to the diaphragm pump. ### Claim 6 (depends on 1) The method of claim 1, further comprising filtering the water after the water passes through the pump. ### Claim 7 (depends on 5) The method of claim 5, further comprising: prior to activating the diaphragm pump: measuring a first temperature of the water in the reservoir; sending the first temperature to a controller; measuring a second temperature of the water in the reservoir after the first temperature is sent to the controller, and when the second temperature falls within a predefined range, activating the diaphragm pump. ### Claim 8 A cold brew coffee device configured to prepare a cold brew coffee beverage, the cold brew coffee device comprising: a water reservoir containing water; a drip mechanism configured to receive water from the water reservoir; at least one tube for transporting water in the water reservoir to the drip mechanism; a coffee grounds container configured to receive water from the drip mechanism, wherein the coffee grounds container is further configured to hold coffee grounds; a pump configured to pump the water in the water reservoir to the drip mechanism, wherein the water passes through the pump; a container for collecting coffee-infused water from the coffee grounds container; a user interface configured to display information, wherein the user interface is configured to receive one or more user inputs, and wherein the user interface is further configured to display a cold brew strength indicator; a controller configured to control the pump and the user interface, wherein the controller is further configured to receive a cold brew strength indication, wherein the controller is configured to control the peristaltic pump to pump the water at a rate based on the cold brew strength indicator, and wherein the cold brew strength indication is based on the cold brew strength indicator; and a power source configured to provide power to the controller, the pump, and the user interface. ### Claim 9 (depends on 8) The cold brew coffee device of claim 8, wherein the power source comprises a portable battery, and wherein the portable battery is configured to be inserted and removed from the cold brew coffee device. ### Claim 10 (depends on 8) The cold brew coffee device of claim 8, further comprising a temperature sensor configured to obtain a temperature of the water in the reservoir. ### Claim 11 (depends on 10) The cold brew coffee device of claim 10, wherein the temperature sensor is configured to obtain a first temperature of the water in the water reservoir and obtain a second temperature of the water in the water reservoir, wherein the controller is further configured to compare the first temperature to a predetermined range, compare the second temperature to the predetermined range, and based on the second temperature falling within the predetermined range, activate the pump to pump water from the reservoir to the drip mechanism. ### Claim 12 (depends on 8) The cold brew coffee device of claim 8, further comprising a water level sensor configured to determine a water level of the reservoir. ### Claim 13 (depends on 12) The cold brew coffee device of claim 12, wherein the controller is further configured to receive a water level value from the water level sensor and determine when the water level value falls below a predetermined value, wherein when the controller determines the water level value falls below the predetermined value, the controller causes the user interface to issue an alert associated with the water level value. ### Claim 14 (depends on 8) The cold brew coffee device of claim 8, further comprising a filter for filtering the water. ### Claim 15 (depends on 14) The cold brew coffee device of claim 14, wherein the filter is configured to filter the water prior to the water passing through the pump. ### Claim 16 (depends on 14) The cold brew coffee device of claim 14, wherein the filter is configured to filter the water after the water passes through the pump. ### Claim 17 (depends on 9) The cold brew coffee device of claim 9, further comprising an electric plug configured to plug into a wall outlet, wherein the battery is configured to receive power from the electrical plug. ### Claim 18 (depends on 8) The cold brew coffee device of claim 8, wherein the drip mechanism comprises a misting nozzle. ### Claim 19 (depends on 18) The cold brew coffee device of claim 18, wherein the drip mechanism is configured to rotate in response to a command from the controller. ### Claim 20 A cold brew coffee device configured to prepare a cold brew coffee beverage, the cold brew device comprising: a water reservoir containing water; a plurality of tubes for transporting water in the water reservoir; a drip mechanism configured to receive water from the water reservoir; a coffee grounds container configured to receive water from the drip mechanism, wherein the coffee grounds container contains coffee grounds; a pump, the pump configured to pump the water in the water reservoir to the drip mechanism, wherein the water passes through the pump; a container for collecting coffee-infused water from the coffee grounds container, wherein the water passes through the coffee grounds prior to being collected in the container; a user interface configured to display information, wherein the user interface is configured to receive one or more user inputs, and wherein the user interface is configured to display a cold brew strength indicator setting; a controller configured to control the pump and user interface, wherein the controller is further configured to receive a cold brew strength indication based on the cold brew strength indicator setting, wherein the controller is configured to control the pump to pump the water at a rate based on the cold brew strength indication; and a power source configured to provide power to the controller, the pump, and the user interface.
