Diploma in Brewing Module 1 - 2025

This lesson is an introduction to the Wort Separation Unit. It offers you the opportunity to ensure that you have the necessary knowledge required to study the unit successfully. Also included is a brief overview of the topics that you will learn.

This lesson deals with the principles of wort separation. Before wort separation, we have completed mash conversion. We will now need to separate the liquid wort from insoluble material. This is mainly the husks from the malt, known as spent grain. We will review the reasons why filtered wort must be clear, and how this affects wort quality. We will examine how the all-important grain filter bed is formed differently, by each of the three most common mash separation devices. These devices are: the lauter tun, the mash filter and the mash tun. We will investigate a typical wort collection profile, which ends with the removal of the spent grain.

Darcy’s Law describes filtration flow rate. We will assess both the variables involved, and what influences them. We will finally use Darcy’s Law to predict the relative flow rates of the three mash separation devices.

This lesson provides the opportunity for you to test yourself on the material covered in Lesson 2 on Wort Separation Principles. It allows you to determine to the level to which you have attained the learning outcomes.

This lesson deals with wort separation technology. The variables of Darcy’s Law are re-visited, to demonstrate how they influence the design of the lauter tun, mash tun, and mash filter. The key design features and control methods of these wort separation devices are identified. Typical operational steps and times are also established for each device.

This lesson allows you to test yourself on the material covered in Lesson 4 on ‘Wort Separation Technology’ and determine the level to which you have attained the outcomes.

This lesson deals with wort separation process control. The different methodologies of measuring and calculating extract recovery are explained and demonstrated. A methodology is explored, as is how to investigate and resolve performance issues with extract efficiency, wort quality, and cycle time.

This lesson provides the opportunity for you to test yourself on the material covered in Lesson 6 on ‘Wort Separation Process Control’.  It will allow you to determine the level to which you have attained the learning outcomes.

This lesson allows you to test yourself on the material covered in all previous ‘Wort Separation’ lessons, and determine the level to which you have attained the outcomes.
