Beer: the science of brewing
About this courseSkip About this course
In this course of 12 modules, our team of academic scientists and brewmasters will introduce you to the science underlying beer brewing. At the end of this MOOC, you will understand the science underlying beer production, and why your beer tastes the way it does!
This MOOC also gives you a sneak peek inside some of Belgium’s most iconic breweries. It features talks from Belgian brewers and maltsters, as well as from some of the most renowned academics on key features of the malting and brewing process.

Learner testimonialsSkip Learner testimonials
"I found so much original content here that I cannot imagine this course won't become a bible for all brewers worldwide. Deep-diving content that definitely places this MOOC in the will-go-back-regularly category. Questions are usually answered by instructors, even with more questions raised to think further or additional resources to read... Experts panel is impressive... Each expert talk completes so well the course. And we had an insight in a Trappist brewery: wonderful!" - former learner
Frequently Asked QuestionsSkip Frequently Asked Questions
What scientific background is required?
This MOOC will discuss and show different chemical reactions and structures, to better explain what is happening during beer brewing. We fully realize that all these reactions can be a bit daunting at first sight. No worries! We do not expect you to memorize all these reaction mechanisms and structures. The most important thing is that by the end of this MOOC, you know some beer-specific compounds (flavor molecules, ageing compounds, …) and how they are formed (as in: from what raw materials are they derived of; what factors affect their formation?) And, if like us, you are a bit of a science geek: feel free to dive a bit deeper into the different reactions!
Worried that you don’t have the proper scientific background?
The big advantage of MOOCs is of course that you can always go over things at your own pace; and even repeat sections that weren’t immediately clear (or even simply skip things that go into too much depth to your liking). Also don't be shy to reach out to us and your fellow learners in the discussion forum to seek for help when something is not clear!
