The GrainFather Hop Spider is a professional-grade filter designed to keep hop trub out of your pump and chiller. Constructed from high-quality 304 stainless steel with a fine micro-mesh, it allows wort to flow freely for efficient extraction while containing hop pellets and whole cones. This results in a much clearer finished beer and prevents clogs in your brewing system's pump and counter-flow chiller. The adjustable hook design fits securely onto the rim of the GrainFather G30 and most other brew kettles.
