Last week the Institute of Masters of Wine announced the results of the annual MW exam and 19 new Masters of Wine have joined the ranks, bringing the total number of MWs worldwide to 340 from 24 different countries. Congratulations to all!

People often confuse Masters of Wine (MW) with Master Sommelier (MS) and vice versa. Both are recognized as the highest credential in the world of wine, sort of like getting your PhD. As a MW, I’m often mistaken for a MS. My response is that I can never pour wine without spilling it somewhere. My tablecloths at home are littered with red wine stains.

The fact is, the Master Sommelier exam is geared towards individuals working in hotel and restaurant beverage service. The MS exam comprises three parts: candidates must first pass the theory section (done orally) where you must demonstrate intimate knowledge of the world’s grape varieties and regions, wine laws and production, as well as knowledge about spirits, beers and cigars; a practical or restaurant service section (that’s where you have to pour wine without spilling!); and finally, a blind tasting of 6 wines (done orally) where you must identify the grape variety(ies), appellation and vintage.

The purpose of the Institute of Masters of Wine is to promote excellence, interaction and learning, across all sectors of the global wine community. Its membership encompasses winemakers, buyers, shippers, business owners, retailers, academics, sommeliers, wine educators, writers, journalists and more.

The MW exam is also three-fold. Candidates must first pass the theory and the tasting exam. The theory exam comprises five 3-hour written papers covering viticulture, vinification and pre-bottling procedures, the handling of wine, the business of wine, and contemporary issues. The tasting exam is also written and includes three 12-wine blind tastings, each lasting two and a quarter hours, in which wines must be assessed for variety, origin, winemaking, quality and style. Lastly, once a pass has been achieved in both the theory and tasting, the candidate must write a research paper. The research paper is an individual project on a topic chosen by the candidate, resulting in a piece of work of between 6,000 and 10,000 words.

I frequently tell interested MW students that in order to be successful in the MW exam, you need to follow the 10,000-hour rule. This rule, as articulated by Malcolm Gladwell in his book Outliers, claims that the key to achieving world class expertise in any skill, is, to a large extent, a matter of practicing for a total of around 10,000 hours. In other words, neither the MS program nor the MW program should be taken lightly.

Brain of Wine

I’m often asked, “Which is harder, the MW or the MS?” That’s impossible for me to answer, because I’ve never attempted the MS title. However, I believe the MS exam would be harder for someone not working in the restaurant beverage industry. Likewise, the MW exam would be more challenging for someone who doesn’t have experience or exposure to all aspects of the wine industry, from grower to general consumer.

Personally, I have no desire or intention of tackling the MS exam. I’m much happier when I can enjoy great wine service at a restaurant with a MS or MS student at the helm. There, I can also appreciate the perfectly clean white table cloths.
