How To Choose A Mash Tun？

Before choosing a mash tun, you need to determine which mashing method you will use. In general, there are three mashed methods:

The first is blended hot water, single temperature (blended hot water), which is Single-Step Infusion Mash. This mashing method does not need to heat the pot, so you do n’t need to consider the heating when choosing the mash tun, only need to insulated and corresponding pipe fittings are sufficient.

The single mashing method is generally between 64 and 70 degrees. It only needs to heat the hot water to the corresponding temperature and pump it into the mashing pot.

The second is the gradual temperature mashing method, which is Multi-Step Temperature Mash. This saccharification method requires mashing of the mashing liquid at multiple temperatures, as follows:

Protein rest 45 ° C to 54 ° C

Beta amylase decomposition 60 ° C to 65 ° C

Alpha amylase decomposition 71 ° C to 74 ° C

Complete saccharification at 77 ° C, ie mash out

The corresponding mashing equipment is selected:

If it is electric heating, electric heating element needs to be installed in the mash tun.

For steam heating, steam jackets are required on the sides and bottom of the tank, which are controlled separately,

For direct fire heating, you need to configure the burner

The mashing method of gradually heating is currently the more mainstream mashing method.

There is a third method of cooking, which is to stir the malt and cold water in the mashing pot and heat it. This mashing method has been rarely used.
