The Zurich start-up Gents was founded by journalist Hans Georg Hildebrandt, a passionate culinary expert. In 2012, Gents launched their Swiss Roots Tonic Water. All recipes are based on Hans’ knowledge of cookery and herbalism he had accumulated over the years. The range now includes a bitter lemon with meadowsweet, a ginger ale made from two African ginger varieties and a ginger beer with Peruvian ginger.
