The wort analysis methods are written, for example, for wort that is produced using the Congress mash method. These methods may also be applied in the analysis of wort which has been produced using a different mash method, particularly the isothermal 65 °C method. However, the reference values listed in the analysis method for Congress wort are not transferable.
The method describes how to determine the viscosity using a rotary viscometer.
Suitable for any wort or mash
These devices measure the torque transferred through a cylindrical liquid layer between a stationary and a rotating disc. This method also allows changes in viscosity, which occur through the action of α-amylase on starch, to be automatically recorded by a plotter or PC.
