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.

Barista Techniques: How to Perfectly Froth Milk and Essential Tips to Consider
Frothing milk is a crucial step in creating an excellent latte. Novice baristas often struggle with achieving the perfect consistency, ending up with overly thick foam. So what exactly makes for perfectly frothed milk? The stability of milk foam depends on the casein micelles and whey proteins in milk, which create surface tension. When steam impacts the milk surface, this tension allows for proper foam formation.
