About the Institute of Masters of Wine (IMW)
The IMW is a membership organisation with an exceptional international reputation. For 70 years, its members – the Masters of Wine (MWs) – have been at the forefront of leadership and expertise in the world of wine. The IMW’s mission is to promote excellence, interaction and learning across all sectors of the global wine community. MWs prove their comprehensive understanding of wine by passing the MW exam, recognised worldwide for its rigour and exacting standards. In addition to passing the exam, members must sign the code of conduct before they are entitled to use the initials MW. This requires them to uphold the highest standards of commercial conduct within the industry. Today, there are 416 Masters of Wine working in 31 countries. The membership encompasses winemakers, sommeliers, buyers, journalists, shippers, consultants, viticulturalists, academics, educators and more. There are 367 students from 40 countries in the 2023-24 MW study programme. The IMW works with 37 supporters and four research and industry associates, who help promote the IMW’s mission. The five principal supporters are Austrian Wine, AXA Millésimes, Champagne Bollinger, Constellation Brands and VSPT Wine Group.
