11 1/2" height x 2 3/4" diameter hop filter with 400 micron stainless steel mesh and a screw cap. This hop filter can be used for boil additions in the kettle or for dry hopping in a keg. The fine stainless steel mesh contains the hop matter in while still allowing the hop oils to infuse into the beer. The filter holds 2 ounces of whole leaf hops and even more pellet hops. Tip: If dry hopping in the keg, force carbonate the beer first.
