Coffee maker and coffee brewing method based on color

An coffee brewing method, the method comprising:

• receiving, using processing circuitry, a color from a color panel of a coffee maker;
• setting, using the processing circuitry, a first temperature and a first time to roast coffee beans in a first roaster;
• setting, using the processing circuitry, a second temperature and a second time to roast coffee beans in a second roaster;
• passing a first amount of coffee beans from the first roaster and a second amount of coffee beans from the second roaster by controlling a first discharge door and a second discharge door, using the processing circuitry;
• starting, using the processing circuitry, a blade of the grinder to grind coffee beans received from the first roaster and the second roaster;
• measuring, using a measuring device, an amount of ground coffee based on a number of cups of coffee requested;
• and
• starting, using the processing circuitry, brewing of the ground coffee received from the grinder.

A non-transitory computer-readable medium storing a program which when executed by a computer, causes the computer to perform a method for brewing coffee, the method comprising:

• receiving a color from a color panel of a coffee maker;
• setting a first temperature and a first time to roast coffee beans in a first roaster;
• setting a second temperature and a second time to roast coffee beans in a second roaster;
• passing a first amount of coffee beans from the first roaster and a second amount of coffee beans from the second roaster by controlling a first discharge door and a second discharge door,
• starting a blade of the grinder to grind the coffee beans received from the first roaster and the second roaster,
• measuring, using a measuring device, an amount of ground coffee based on a number of cups of coffee requested;
• and
• starting brewing of the ground coffee received from the grinder.
