The Water Course

Course & Certification

The Water Course is a first of its kind, designed to give baristas and cafe owners everything they need to take charge of their water chemistry. Absorbing this information will help you save thousands in potential maintenance costs brought on by limescale and corrosion damage to coffee equipment. You will learn how to maintain and operate water filtration systems, and how to optimise your water to produce higher, juicier extractions. 

The course is structured across five chapters and a detailed prologue. In the prologue, we get students up to speed with all the fundamentals of water chemistry and explain how minerals make it into our water. Chapter One teaches you everything you need to know to test your water’s hardness. 

In Chapter Two we discuss everything else in water — contaminants, nutrient runoffs. In short, we cover every base so that you know exactly what;’s in your water and how it can potentially damage your coffee machine. 

In Chapter three we learn how to use the powerful Langelier Saturation Index to make accurate predictions on what your water will do. We learn how to diagnose limescale and corrosion and how to avoid it.  

In chapter four we learn how to take control of water’s mineral content and explore three available systems for manipulating water chemistry. After this chapter, you will be able to get your water exactly where you want it.

The course concludes with a rundown of the sensory implications of water chemistry. We look at innovations and research into how water can make coffee taste better. In the final chapter, we then come to the final assessment. This challenging quiz is designed to make sure you understand every important learning outcome.

All of our courses and certifications are available through BH Unlimited as a monthly subscription or as a single course purchase, giving you access for life!
