A uniform, symmetrical coffee bed serves as proof that we've controlled the water flow perfectly during extraction. However, for many coffee enthusiasts, achieving that perfect, even extraction remains an elusive goal.

Why Does the Used Coffee Bed Split into Two Layers?
Last week, we discussed why pour-over coffee requires circular water pouring. We learned this technique improves extraction efficiency while preventing water from flowing chaotically, helping establish a controlled flow path to achieve uniform extraction. When the used coffee grounds form a "bowl-shaped" pattern, with the grounds along the filter cup's edge creating a distinct layer from the bottom, it's often a sign of your brewing technique. This separation indicates that water has flowed through the coffee bed in a way that created channels, potentially leading to uneven extraction. Understanding this phenomenon helps coffee enthusiasts refine their pouring technique for better extraction consistency.
