The Bacardi executive who recently caused controversy in the Scotch industry by suggesting that flavourings should be permitted has left the firm suddenly.

Neil Boyd had worked for Bacardi for nine years, having spent the past four years as global brand director of Dewar's, the world's sixth biggest Scotch brand.

It is unclear what is at the root of this unexpected departure. Under Boyd's tenure, the brand has halted its slide in the US, the Dewar's portfolio has expanded, Aberfeldy single malt has been launched and the World of Dewar's visitor's centre has opened.

Boyd is understood to be looking for new opportunities within the Scotch whisky industry.

No-one was available for comment at Bacardi when contacted by just-drinks today (15 June).
