2-3/4" X 11-1/2" Screw Top Dry Hopper. Dry hopping in your keg was never so easy. The 300 micron stainless steel mesh allows hop oils to flow into your beer, but keeps the hop material inside. This filter will hold up to 2 ounces of leaf, even more pellet. Want to remove the filter after a week in your full keg? Sanitize & attach a large rubber bung with a piece of fish line to the eyelet in the top. Insert into your keg. They bung will float for easy removal. We recommend adding this filter to your keg after force carbonation (if that is your chosen method) You can also use this hop screen in your boil pot.
