Effective stirring The coffee stirrer needle, made of durable materials, is designed to withstand regular use without bending or breaking. It effectively stirs the ground coffee in the basket, breaks up agglomerates, and improves extraction uniformity and rate. Prevent spillage By using the needle with a coffee ring, ground coffee is prevented from being stirred out of the basket during brewing. This ensures a clean, mess coffee experience. size and impact Extensive testing shows the needle diameter is less than 1 mm. This size enables efficient stirring without any negative impact on the coffee's flavor and characteristics. Key attributes Function: stirs ground coffee in the basket and breaks up clumps for more uniform extraction Material: durable construction designed for regular use Size: diameter under 1 mm for efficient, unobtrusive stirring Performance: improves extraction uniformity and rate while minimizing spill risk Use scenarios 1) Daily home brewing: use to break up clumps in the basket to achieve more consistent extraction. 2) Brewer setup with a coffee ring: pair the needle with a coffee ring to prevent grounds from escaping the basket during brewing. 3) Small or crowded baskets: the slender needle provides precise stirring without disturbing surrounding grounds, helping maintain clean operation and consistent flavor.
