Maven Spirits is the consultancy of Dr Jack Mayo, Consultant Master Distiller & Distillery Operations, based in Edinburgh, Scotland, but with global mobility. Jack brings a rare combination of analytical training and practical experience in spirits production, with whisky at the centre of his work.

Projects can call for a broad view or a very specific answer. Jack has worked with clients in the UK, Ireland, Portugal, Slovenia, Italy, India, Japan, New Zealand and Ethiopia, and is available to travel to inspect client facilities and manufacturers’ sites. The aim is clear thinking, sound engineering and recommendations that make sense on the production floor.
