Prevents overflow and uneven extraction: Designed to break up clumps and reduce channeling of fine coffee during brewing, so water flows evenly through the grounds and overflow from agglomeration is minimized. Stainless steel construction: Made from corrosion‑resistant stainless steel that resists rust and is foodsafe for longterm use and easy cleaning. Arc‑needle design protects filters: The curved needle tip lets you gently stir grounds without piercing or damaging filter cups, maintaining filter integrity and consistent flow. Wider mixing area and secure grip: A thoughtfully proportioned head provides a broader mixing surface for faster, more uniform distribution of grounds, while the handle design reduces the chance of slipping during use. Simple, controlled action: Use a gentle rotating stir to evenly distribute coffee and avoid over‑agitation; the tool's shape makes even stirring precise and repeatable. Practical details: Function: Distributes fine coffee evenly and prevents overflow from clumping or channel effects during brewing. Material: Corrosionresistant stainless steel for durability and food safety. Performance: Promotes consistent extraction by enabling controlled, even stirring without damaging filters. Typical use scenarios: 1) Home pourover: When brewing with fine grounds, stir gently once or twice to break clumps and prevent sudden overflow, yielding a more balanced cup. 2) Singlecup or filter brewing in a café: Use between pours to eliminate channeling and ensure consistent extraction across multiple singleserve brews. 3) Delicate paper filters: The arc‑needle tip lets you agitate grounds without tearing filters, preserving filter performance and brew clarity. What it solves: Reduces overflow and uneven extraction caused by agglomeration or channeling, protects filters, and gives you a reliable, repeatable stirring tool that improves consistency in everyday brewing.
