The Opaque Beer Brewing programme has been presented by the University of Pretoria and Enterprises University of Pretoria annually for more than 15 years and has continuously improved through interactive feedback with clients. The programme is focused on providing brewers in opaque beer (sorghum beer) breweries and other related beverage producing operations – such as fermented non-alcoholic beverage plants (mageu and similar products), clear sorghum beer and non-alcoholic malta breweries and distilleries – with required scientific and technical knowledge and skills so they are capable of performing their duties with an acceptable level of understanding.
The programme also provides essential knowledge which can be utilised by Quality Control Technicians, Quality Control and Assurance Managers, Production Managers, Procurement Managers, and Brewery and Plant Managers.

Programme content
The course comprises four individual, interactive distance learning modules and two written examinations. Assessment of each module will be through a written test/assignment.
The manager of the participating company needs to appoint a mentor for the students on the course. The mentor will be a person well-versed in the technology and practice of opaque beer brewing or related beverage producing operation or associated industry. Their role will be to help their student understand the material in the modules and will receive scientific and technical advice from the course presenter as and when required.
In addition, the mentor will be responsible for getting the course notes and assignments to the students and sending the students’ assignments to Enterprises University of Pretoria, and will also be responsible for the venue and supervision of the final written examinations. Communication between the course presenters, course coordinators, mentors and students is primarily through email.
Please note that there may only be one mentor per company, however, if someone needs to stand in for that person for a given period, an assistant may be appointed and that person will only be contacted on the mentor’s instruction.
Following completion of the modules, a short four-day intensive Residential Study Period will be undertaken. The Residential Study Period will be used to provide practical and technical information relevant to the major items of brewing equipment encountered in opaque beer brewing as well as practical experience in laboratory analysis.
Confirmation of the successful completion of the course will be on the basis of written examinations where the following rules apply: • The total average achieved for assignments must be higher than
50% to qualify for the final examinations.• Any assignment failed may be repeated once on written request
from the mentor to the course administrator.• The total average achieved in the two final written examinations
must be more than 50% to qualify.• An oral final examination may be taken if deemed appropriate.

Examinations must take place within the country of residence of the students, under the direct supervision of the mentors.
