The original Tonic Water and Ginger Beer products are now joined by 125ml bottles of Light Tonic Water and Ginger Ale.
The Light Tonic Water has 30% fewer calories than the company’s standard Tonic Water, while the Ginger Ale is being promoted as the perfect accompaniment to whisky.
Fentimans has introduced presentation boxes and cocktail menus to accompany the new mixers.
Meanwhile, the company has launched a new competition giving consumers the chance to win a holiday in a British stately home.
The Rule Botanicals competition will be highlighted on limited edition Fentimans labels from the end of this month.
