"Dan created his own version of a hop-back in a Cornelius keg. He hand-sewed a stainless steel window screen into a cylindrical basket and fastenable lid that fits inside the corni keg. He fills the basket with his aroma hops, then steeps them for 10 minutes, before using the corni keg’s in and out valves to sparge the “hop tea” into the fermenter with the fresh wort."
