Coffee beans are the second most traded commodity. The sad fact is that most coffee drinkers are drinking badly prepared coffee. The coffee grounds are prepared days or weeks before it is used. Much of the flavor is lost during this time. The brewing water is too hot which changes the taste. Also, the water spends too little or too much time with the grounds which also changes the flavor. The ultimate coffee machine would need the following items (in no particular order).
- A coffee bean grinder
- A water heater with a temperature sensor
- A microcontroller for control and timing
- Motors
- A separator for separating the grounds from the water (a filter or a centrifuge)
