IBD – Diploma in Distilling

Diploma in Distilling

Who should attend?

Typical candidates are team leaders, operational managers and technicians. They take the Diploma in Distilling either as a stepping-stone to the Master Distiller qualification or as an end in itself. IBD members who have successfully completed the programme and passed their Diploma level examinations are awarded the use of the post nominal “Dipl. Dist”.

How will you benefit?

The objective of the Diploma in Distilling is to give international recognition of comprehensive knowledge and understanding of the principles of Distilling Science and Technology. It is a measure of the candidates’ theoretical knowledge of distilling science and technology. It is an important qualification in its own right, as well as representing the necessary thorough grounding for the application of those principles for the Master Distiller Examination.

Typically Diploma Level candidates are team leaders, operational managers and technicians. They take the Diploma Level qualification either as an end in itself or as a stepping stone to the Master Level qualification. It provides them with the theoretical knowledge and understanding that enables them to do their jobs better by improving the basis on which decisions are taken.

IBD members who have successfully completed the programme and passed their Diploma Level examinations are awarded the use of the post nominal “Dipl. Dist”.

Whilst there is neither educational qualification nor work experience specified for sitting the Diploma Level examinations, candidates must satisfy themselves (and the Examiners) that they have sufficient scientific knowledge to understand the subject matter.

  • Process technology

Progression Routes – Upon successful completion of the IBD Diploma in Distilling, the candidate may progress to the following qualifications: 

Master Distiller: The Master Distiller is the highest level of distilling qualification offered by the IBD. It is a measure of the level of a candidate’s competence in the technical management of the distilling processes. Although they are competence-based assessments, it is essential that the candidate has a background which includes a detailed technical knowledge of the scientific theory and principles that underpins the process 

Please note: if you are interested in any of the iBD courses and qualifications, you will need to register directly with the IBD on the following website: https://www.org.uk/learn/

You will however, be able to choose where you sit the examination and we are a centre for the IBD examinations.
