Convex Bottom Design Unique shape directs water flow toward the center of the puck. Reduces edge channeling and ensures full, even saturation. Creates a balanced extraction with deeper sweetness and a fuller body. Big Bang Hole Pattern Developed exclusively for this convex geometry. Denser hole distribution in the center increases water flow where the coffee bed is thickest. Produces consistent crema, balanced texture, and enhanced flavor definition.
