A device used at the bottom of a lauter tun, to strain the wort from the grain. Manifolds are commonly constructed from pieces of metal or plastic tubing, connected in a flat ring or "H" shape, into which holes or slots have been cut. The tubing is attached to a fitting which passes through the wall of the lauter tun, to allow the wort to be drawn off. Manifolds can also be constructed using pieces of welded tubular metal screen. See also, false bottom.
