Adjustable flow control valve The kettle includes a builtin adjustable flow control valve that lets you set the water flow for your brew method. This helps you dial in brew strength and flavor, reducing under or overextraction and giving you consistent results. Precise pouring with a narrow mouth The narrow mouth design concentrates the pour, enabling precise saturation of the coffee grounds. This helps extract the flavors and maintain even extraction across the bed. 90degree angle flow The right angle flow design allows for steady pouring while maneuvering around coffee grounds. It supports a controlled, consistent pour with less splashing and drips, even from awkward angles. Use scenarios Home pourover setup: adjust the flow to match your preferred strength and flavor profile, enabling repeatable, cafélike results. Limited counter or equipment space: the 90degree angle flow helps you pour accurately into tall mugs or narrow vessels without crowding the workspace. Multicup brews or busy sessions: maintain a consistent pour and flow to ensure uniform extraction across successive brews.
