The review was kicked off following the restructure of the company's marketing department at the start of this year. William Grant is understood to be talking to a number of undisclosed advertising agencies and it is thought to be close to making a decision.
The Glenfiddich brand has become synonymous with its stag icon, which will remain a central plank of its marketing strategy. The brand is the world's biggest-selling single malt whisky.
Glenfiddich's global advertising is currently handled by the US-based agency Merkley & Partners, which is part of the Omnicom Group. The advertising account was previously split between VCCP and Merkley & Partners, but was consolidated into the latter following a roster review in 2004.
