This exciting new device is virtually plug free and captures up to 95% of the brew kettle particulates! As usual, we took a completely fresh approach to the pellet hop problem and through a year of very tasty research we developed the HopBlocker. It capitalizes on preferential flow to direct the clear wort to the kettle drain and keep the particulates at the bottom where they belong. The HopBlocker can easily bring a pound of pellet hops to its knees. Works best in BoilerMaker pots, but can be adapted for use in other manufacturers pots and kegs too. Measures 5.625" tall by 3.75" wide at base.
