Auto Brew Ratio has two modes: Mass Mode and Ratio Mode.
In Mass Mode, the barista programs the desired finished beverage mass. The barista activates the brew group by selecting one of the programmed beverage mass buttons. When the desired beverage mass has been reached, the machine automatically stops the brewing process.
Mass mode is best applied in cafe settings where the barista weighs the ground coffee in the portafilter for every shot, and has a specific target weight for the finished beverage.
Using ratio mode, the barista programs the preferred brew ratio into the machine. When preparing to brew, the barista places the loaded portafilter on the drip tray scale, allowing the espresso machine to weigh the ground coffee. The barista may then engage the portafilter and activate the brewing cycle by selecting one of the programmed brew ratio buttons. The Ratio Mode will automatically stop the shot when the correct brew ratio is achieved.
Ratio mode is best applied in coffee bars that do not weigh every ground coffee dose, or those cafes that would like to eliminate the step of weighing and correcting the coffee dose to a tenth of a gram. Auto Brew Ratio allows the barista to eliminate the step of weighing and correcting the coffee dose, while still consistently achieving the same brew ratio.
