Precise control over espresso brewing with flow profiling techniques
Jan 01, 2023
Flow profiling is a technique used in espresso brewing to precisely control the speed of the water being brewed. This can be achieved using a flow profiling mask, which Profitec Pro 700 or Rocket R nine one.
A common technique used with flow profiling masks is called "ramping pre-infusion" and involves starting with a low water flow and gradually increasing the airflow over the first ten to fifteen seconds of the extraction process. This helps reduce the likelihood of channeling (uneven extraction), the phenomenon responsible for the inconsistent extraction of espresso shots with clear/smooth flavors, by mixing coffee grounds with water.
The technique of reducing the flow rate as the extraction process nears its end is another common application of flow profiling machines. As the coffee bean becomes less resistant during the extraction process, the water flow naturally increases as the process nears its end. By maintaining a constant flow rate using flow control, a desired power output can be targeted regardless of how much Grind This allows you to discover new recipes and flavors that you might not have been able to try otherwise.
Some flow profiling machines, including Profitec Pro 700 and Rocket R nine one, uses a paddle or knob to regulate the opening of a valve between the boiler and the boiler chamber. This provides instant control over the speed of movement of the group and also allows for a clickable icon on the front of the package. Using flow profiling technology, you can improve the quality and consistency of your espresso brew. You can get even better results by installing a flow profiling upgrade kit, which is recommended for Profitec-espresso machines with an E61 group head.
