[tps_title]Step 4: Fit the Manifold[/tps_title]
Manifold is a twisted metal contraption made from either rigid or soft copper tubing. A manifold has a small opening into the bottom part of each tube. This allows the wort to be drained off as the grains ferment into beer. You can choose to make your own manifold if you’re hardcore like that or you can get a store-bought one. Either way, make sure the manifold design covers the most area of the pumpkin opening you carved, snugly. It should not move around.
