The Morning Machine has a built-in scale that helps provide you with consistent brews. There are also two thermal sensors coupled with a PID (Proportional Integral Derivative) controller, allowing you to set your brew temperature to highlight each coffee’s nuances. Lastly, you can control the brew pressure via the Intermittent Wave Brewing System (patent pending) to enhance your coffee’s mouthfeel and texture.
There has been a shift in coffee brewing with the use of scales. Compared to simply relying on volumetric measurements (from a flow meter), scales provide you with accuracy, which leads to repeatability and room for experimentation. Instead of simply eyeballing the liquid espresso and crema, a scale provides weight-based brewing, where the output is instantly measured and displayed. This allows you to brew to more consistent-tasting cups of coffee.
Another factor that affects the coffee’s flavour is its brew temperature. According to the Specialty Coffee Association's The Coffee Brewing Handbook by Ted Lingle, various coffee flavour components such as malic acids, citric acids and sucrose, each require different temperatures for a balanced cup.
The third key feature of the Morning Machine is the Intermittent Wave Brewing System, which is used to control pressure. This system affects the coffee’s Total Dissolved Solids (TDS) and allows exploration of how pressure can affect your coffee’s taste.
One of the Morning Machine’s capabilities is the Bloom & Brew, which uses the Intermittent Wave Brewing System. In this process, the coffee is pre-wet, followed by a short pause, and then the brew finishes with a low pressure.
