Pulse brewing is defined as the action of a microprocessor controlling a solenoid so that it can be opened and closed several times in one cycle, instead of just once with a simple timer. Here are four reasons to pulse brew your coffee.

1. To prevent a large volume of water from overflowing a pour-over pan. The microprocessor can be programmed for the total water volume desired. You can also program it to pulse the inlet solenoid, thus slowing down the rate of water going into the pan.

2. To prevent a large volume of water from overflowing the grounds in a filter basket. The microprocessor can be programmed for total water volume desired. Plus, you can program it to pulse an inlet valve or outlet valve to slow the rate of water going into the filter basket to match the drain time.

3. To prevent fine ground coffee from overflowing the filter basket.The microprocessor can be programmed for total water volume desired. It can then be programmed to pulse an inlet valve or an outlet valve to slow down the rate of water going across the grounds in the filter basket.

4. To maintain a higher and more consistent brewing temperature. A liquid level sensor can control the inlet water valve so that cold water comes into the hot water tank only as it is being used. This is usually only applicable to brewers with an outlet valve over the filter basket.

The benefits of pulsing water control are to fine-tune the flavor profile and concentration of the beverage. And pulse-brewing technology can be programmed to increase or decrease the rate water flows through an inlet water valve or an outlet valve going into the filter basket. This will increase or decrease the amount of time that water is in contact with the grounds. Longer contact will increase the extraction of the coffee flavors while shorter contact will reduce it.
