The move follows the takeover of Onken by the Dr Oetker Group last year and comes as it announces ambitious plans to double sales within three years.
To launch Smooch, Revolver is targeting health magazines, women's glossies and the shopping pages of the national press.
In addition, in-store sampling in August across the UK will centre around the use of street theatre performers, said Revolver MD Martin Ballantine.
'We will be creating theatre for people in-store, using actors rather than just the usual numpties handing out leaflets,' he told PRWeek.
The launch of the fruit-layered yoghurt will be supported by a national television campaign, breaking in July.
Ballantine reports to recently appointed Onken head of marketing Jackie Duff, who worked with Revolver at her previous post as marketing director for Unilever's now-defunct meal kit business Rocket.
