What is CAS in Coffee Excellence?

The graduate certificate programme CAS (Certificate of Advanced Studies) in Coffee Excellence is an online programme designed at the highest level of the coffee training path. Coffee professionals are offered a comprehensive science-based education on coffee along the whole value chain, through a flexible, remote learning course format. The course provides new insights and perspectives on all aspects of coffee, from green coffee to roasting and extraction. Along the way students will be assessed to ensure they are mastering the material.

Why CAS in Coffee Excellence?

This part-time distance learning graduate certificate programme aims to help you develop and deepen your knowledge of the coffee value chain; from crop to cup. Developed by a team of experts in coffee science and technology, you will gain scientifically-based expertise through an online course format. An additional advantage of this course will be an expansion of your network of professional relationships within the coffee industry and the establishment of contacts with relevant experts.

• Are you a a person who wants to enter and grow in the coffee sector? We will equip you with all the knowledge, networks and insight needed to find your own personal journey in coffee.

Although not explicitly necessary, participants will find a basic knowledge of biology and chemistry to be helpful.

What can I expect to learn?

The course has been developed by coffee scientists at the Coffee Excellence Centre of the Zurich University of Applied Science. The Institute of Chemistry and Biotechnology at ZHAW is a world class research institute, and our experts will support and guide you through the learning journey to achieve the following broad academic goals on completion of the course:

• Acquire in-depth knowledge and a comprehensive overview of the science of coffee from crop to cup
• Apply a multidisciplinary scientific and practical knowledge of all processes involved in the coffee value chain
• Take a fact-based approach and critically examine all aspects of coffee
• Integrate knowledge on selected coffee topics into professional contexts
• Enlarge your professional network and make contacts with experts in the coffee sector.

The course curriculum is divided into three distance learning modules as follows:

• Module A - The Coffee Fruit: From Tree to Trade
• Module B - The Coffee Bean: Transformation and Composition
• Module C - The Coffee Cup: Extraction and Sensory

In this module, we will explore all aspects of the coffee cherry in origin countries; from its discovery to how different coffee species and varieties evolved worldwide. We will also consider important aspects of botany and the role of agronomic practices on the farm to improve yield and quality while developing strategies to combat pests and diseases. We will discuss harvesting as well as processing aspects until green coffee is obtained. Finally, we will take a look at the economics of coffee production, sustainability and different models of trade.

*ECTS = European Credit Transfer System. ECTS is a standardized and comparable student performance assessment system across Europe. One credit is awarded for a workload of 25 - 30 hours (contact time and self-study). More information is available here.

To successfully complete the course, participants will be expected to commit to a workload of approximately 7 to 8 hours per week. Each module consists of six sessions, and participants have 2 to 4 weeks to complete one session. Within that time, participants can plan their study time freely.

It is delivered as a mix of interactive and self-study materials which include:

• Online lectures and group discussions in virtual classrooms
• Quizzes
• Live-lab sessions
• Practical exercises at home
• Office hours with module tutors
• Additional content for further reading

For the three Modules (A to C), your learning journey will be assessed online as you progress through the curriculum as well as a standalone self-learning research project to be submitted at the end of each module and a module assessment (multiple choice questions). For this practical part, participants will receive coffee samples from ZHAW. Virtual classrooms and other activities and exercises need to be attended and completed (at least 80 %) in order to pass the Module.

What does it involve?

You will be required to complete 375 hours of study or 15 ECTS points to gain your diploma. This corresponds to 7 to 8 hours per week spread over the 15 months period of the CAS programme. 

Each Module (21 weeks) is generally structured as follows: 

• Introduction: 1 week 
• Sessions 1 - 6: 15 weeks including Virtual Lab Sessions in Module B and C
