The review coincides with the launch of an ad campaign to support WKD Core, the 4.5% ABV apple cider variant it launched in May.
The review is being handled by Beverage Brands' marketing communications manager, Eva Petrou. The WKD ad account, held by Big Communications, is not thought to be affected.
The launch of WKD Core is the first time in WKD's 13-year history that the brand's name has appeared on a non-spirit-based product.
The campaign, led by outdoor advertising, breaks next month, supported by press and online activity.
It attempts to avoid the 'rustic' connotations normally associated with marketing in the cider category in favour of a more modern sensibility.
A spokeswoman denied that the media account was being reviewed.
