Wedge Wire False Floor for Mash Tuns

Wedge Wire False Floor for Mash Tuns 

When talking about mash tun floor in beer brewing, it comes with a question that using a perforated or wedge wire false bottom. While with proper crush size and monitoring the flow rate to minimize pressure differential inside, both bottoms can works well. However, usually, a wedge wire false bottom is more common in commercial brewing process, that is because: 

Firstly, it provides more open area. 

Secondly, it supports the grain better as the largest gap width is smaller than with a perforated bottom.

Thirdly, it won't trap grain easily (grain will get trapped when it gets into the perforated hole. But thanks to the inverted triangle shape of the wedge, grains can often work itself out and fall down to the bottom)
