Key benefits and purpose: The Brew Hops System filter barrel hopper strainer contains hops while keeping debris out of pumps, chillers, and finished beer, delivering clearer beer and better taste. It is also suitable for filtering coffee and making compost tea, and can be placed into a boil pot as needed. Built to last: Features a 300400 micron mesh that resists wrinkling and damage. The frame is made from firm stainless steel for strength and longevity, and it resists rust, corrosion, heat, and pressure to help maintain hygiene and beer quality. Easy to use: Lets you load a large amount of grains at once. It is easier to use than mesh bags because it sinks to the bottom of the keg without weighing it down. Easy to clean: Turn the hop filter upside down and spray the mesh from the outside with a garden hose to remove residue. It can also be dishwasher safe as a separate load with no soap. Clean it promptly after use. Specifications and compatibility: Mesh size 300400 microns; frame made of stainless steel. Designed to work during brewing, coffee filtration, and compost tea preparation, and can be placed into a boil pot when needed.
