False bottom screens for grain brewing work principle

False bottom screens consist of a perforated plate or a wedge wire screen that sits at the bottom of the mash or lauter tun. The grains and hot water mixture are added on top of this screen. As the grains steep in the hot water, the wort is formed. The liquid wort easily passes through the holes or mesh of the false bottom, leaving behind the solid grain bed.

The design of the wedge wire false bottom ensures that the grains remain undisturbed during the sparging process, preventing grain particles from entering the wort. This results in a clearer and cleaner wort, which is crucial for producing high-quality beer.
