A mash tun is a beer brewing vessel where the magic of converting grains into fermentable sugars occurs. Among the various designs of mash tuns, the false bottom mash tun stands out as a key player. Today, we will learn about how a false bottom mash tun works.
Understanding the Mash Tun
The mash tun vessel is where milled grains meet hot water in a process known as mashing. During mashing, enzymes break down complex starches in the grains into simpler sugars, creating a sweet liquid known as wort. This wort is a crucial precursor to beer, as it contains the sugars that yeast will later ferment into alcohol.
Mash Tun False Bottom
A false bottom is a wedge wire screen panel, creating a barrier between the grain bed and the rest of the vessel. Its primary function is to separate the liquid wort from the spent grains during lautering, the process of extracting the sweet wort from the mashed grains.

How Does a False Bottom Mash Tun Work?
▪ Mashing: The milled grains are mixed with hot water in the mash tun. Enzymes go to work, breaking down starches into sugars, creating the wort.
▪ Lautering: Once the mashing process is complete, it's time to separate the liquid wort from the spent grains. This is where the false bottom comes into play.
▪ False Bottom Design: The false bottom screen is designed with precision-engineered v-shaped slots that allow liquid to flow through while holding back the solid grain bed.
▪ Grain Bed Formation: During lautering, the grain bed forms on top of the false bottom. This grain bed acts as a natural filter, trapping unwanted particles and allowing the clear wort to flow through.
▪ Wort Collection: The clear wort passes through the wedge wire false bottom, leaving the spent grains behind. The wort is then collected and transferred to the next stage of the brewing process.
