Turbulence is created as the water passes through and over the coffee. It should cause the particles to separate and create a uniform flow of water around them for proper extraction. It is essential to this process to keep sprayheads clean.
- Ensure coffee brewer operates with proper “turbulence” or agitation of the water in contact with the coffee grounds.
- Insufficient turbulence can severely limit extraction.
- Brewer’s sprayhead and brew basket create turbulence.
- Sprayhead must be in place and not clogged by coffee or water residues.
- Improper bed depth of coffee in the brew basket is common cause of insufficient turbulence.
