Four new Masters of Wine

Four new Masters of Wine

It gives the Institute of Masters of Wine great pleasure to announce four new Masters of Wine. The new Members of the Institute – two from the USA and two from the UK – are Cassidy Dart MW, Caroline Hermann MW, Simon Milroy MW and Martin Reyes MW.

There are now 370 Masters of Wine living in 28 countries.

The new Members have proved their understanding of all aspects of wine by passing the Master of Wine examination, recognised worldwide for its rigour and high standards. The MW examination consists of three stages, including theory and practical exams, and culminates in the submission of a final research paper, an in-depth study on a wine-related topic from any area of the sciences, arts, humanities, or social sciences.

In addition to passing the examination, all MWs are required to sign the MW code of conduct before they are entitled to use the initials MW. The code of conduct requires MWs to act with honesty and integrity and to use every opportunity to share their understanding of wine with others.
