He replaces Chris Searle, who is standing down as chair of the group.
The WSTA Spirits Committee offers a forum for member companies to discuss and guide all aspects of policy and trade relating to spirit drinks, such as production, taxation and legislative matters affecting the sector.
The UK is one of the world’s largest producers and exporters of spirits and the spirits industry supports hundreds of thousands of UK jobs. Some 18% of direct employment in the European spirit industry is in the UK, the highest contribution of any member state.
Despite the importance of the sector to the UK, spirits duty has increased by 44% since 2008 and tax now accounts for 77% of an average price of a bottle of spirits.
O’Driscoll said: "I look forward to building on the excellent work achieved by the committee as it continues to address many important issues affecting the industry from work on free trade deals to fairer tax treatment."
O'Driscoll has more than 20 years experience in the UK drinks sector. He became joint managing director at Beverage Brands in 2009 before taking on his current role in 2013.
