Wetting
The grounds begin to absorb the hot water from the sprayhead and release gasses from the coffee. For consistent extraction from all parts of the coffee grounds, you must evenly wet the entire bed of coffee in the first 10% of the brew cycle time.
Extraction
The water-soluble materials dissolve and move out of the coffee grounds and into the water. The best flavors are extracted at the beginning of the process as seen in the Brew Cycle Time table.
Hydrolysis
Through this chemical reaction, the materials created during extraction break down further into water soluble proteins and sugars.
