Loved all the theory and science in the morning. And also enjoyed the practical in the afternoon. A fabulous day!

John did an excellent job in covering every part of the perfume industry and was very knowledgeable and generous in sharing his knowledge with us. As John/Cotswold Perfumery is a 'compounder' it was a great introduction to the whole Industry and would certainly be an excellent way to start on the 'perfume journey' via the facilities/services he can offer, so I think the five days although intense did cover all aspects and those who attended left with a good understanding of the commitment needed to be a Perfumer. I feel the Course did everything it said 'on the tin' and was excellent.

Diana - December 2025

Very well organised and with clear information.
Personally, I feel that this course is excellent value for money, and unlike other online courses or much lengthier certified courses, this course is distinctive in just how much content it fits into the 5 days, as well as the amount of hands on experience, and the ability to tap into John's vast knowledge.

I very much enjoyed the course, and in particular the delivery by John, which was well paced, and who masterfully combines complex technical information with humour, and interesting stories/examples that help you to retain the knowledge. The quality and breadth of content material within the course pack was/is excellent, and a real value add bonus was the spreadsheets for calculating formulations. Honestly, I would do this course over and again! It was a joy, and has ignited my onward studies not only in aroma chemistry, but the broader subject of organic chemistry.

John was extremely knowledgeable and a fun teacher! Making the perfume was great and the theory aspects were very interesting.

I was fascinated by everything that we were taught and by doing the practical parts. I could have listened to John for such a long time. He had so much knowledge to share.

Lianne

The knowledge transfer from John was outstanding, easy to digest and so wide-ranging covering so many aspects of creating a perfume and beyond (multidisciplinary), an absolute masterclass and so enjoyable!

Best part of the course was how John delivered the material and executed and organised the course. Best bespoke perfumery course the UK has to offer.

It was an inspirational day, thanks to John's teaching style and enthusiasm. It has inspired me to continue my interest in making liquid soap and to attend the second course. Thank you to John and the team for a wonderful day.
