This High Quality Food Grade Hop Spider keeps hops together during the boil. It can be used on all appropriate sized boil pots, including the Grainfather. Made with a coarser, 800 micron mesh, for maximum wort flow and increased hop utilisation. Although we do not believe this is needed with the Grainfather brewing system, many of you would like to purchase one for your hops. We have therefore designed this with a specifically fitted hook design which can be hooked onto the side of any brew pot or the Grainfather system support ring. Perfect for those of you who would like the reassurance of a hop spider when brewing. This spider can be used for any kind of hops, including hop pellets. Specification: Diameter: 15 cm / Length: 30 cm. Material: 800 micron 304 grade stainless steel mesh, with stainless steel support band and single hook.
