How does turbulent flow and agitation affect coffee beds?
Agitation of the coffee grounds during brewing is crucial for achieving a thorough extraction. A rougher water stream with controlled turbulence can distribute water evenly among the coffee particles, ensuring a more consistent and flavorful brew. However, if the water stream is too irregular or only tiny droplets fall on the slurry, agitation may not reach deep into the coffee bed, resulting in uneven extraction.
