Three new Masters of Wine have been announced today, taking the total number of MWs to 419 from 31 countries.

The latest members of the The Institute of Masters of Wine (IMW) are of three different nationalities, based in two countries, with the drinks business offering its congratulations to: Claire Blackler MW (UK), Michael Henley MW (New Zealand) and Siobhan Turner MW (UK).

With this morning’s announcement, there are now 419 MWs globally – 268 men and 151 women living or working in 31 countries. Since the first exam in 1953, 496 people have become an MW.

Claire, Michael and Siobhan join the 10 new Masters of Wine announced in February to form the 2021 vintage of 13 MWs.

The top countries where MWs are based around the world are Australia (28), Canada (10), France (18), Germany (10), New Zealand (16), the UK (209) and the US (57).

Michael Henley MW (New Zealand)

Working in the local bottle store to help fund his university lifestyle opened a door into the world of wine that Mike happily walked through. He holds a BSc in zoology as well as diplomas from WSET and in viticulture and oenology. Mike spent the first years of his career travelling and working vintages in South Africa, California, Marlborough, Oregon, Barossa Valley and Spain. Settling down in London and working at Christie’s Auction House exposed him to fine and rare wines. After a transfer to California with Christie’s, he moved back to New Zealand and took up a role with the newly opened Craggy Range Winery. During his time with Craggy Range, he returned to London to oversee the European markets. After that, he returned to New Zealand and held chief executive roles with Trinity Hill Winery and Aotearoa NZ Fine Wine Estates. Based in the sunny Hawke’s Bay region of New Zealand, Mike struggles to keep control over his two teenage daughters, two cats and two dogs. In his spare time, body willing, he enjoys playing golf, tennis and cricket. He is a director of New Zealand Winegrowers, Hawkes Bay Winegrowers and Hawkes Bay Tourism.
