Mash Tun

The purpose of the mashing process is to extract starch from the malt and convert it into fermentable sugar, which yeast will later convert into alcohol and carbon dioxide. The two enzymes responsible for starch conversion, alpha- and beta-amylase, function optimally at a pH of approximately 5.2 to 5.6. The pH of the mash will determine how much grain starch will turn to maltose and how much will be dextrins. A pH in the lower part of the range, even as low as 5.0, will produce beers of drier taste, less body, and lower malt character. A pH around 5.7 will produce heavier-bodied, sweeter beers. The mash is then filtrated to create a sweet wort (brewing liquid).

pH Sensors for Mash Tun

Goal of Measurement:
The pH of the mash has a great influence on enzymatic activity. It also affects the ratio between maltose and dextrins and thus determines taste, body and malt character of the beer.

Controlling pH also helps accelerate the process and provides better foam control.
