Hero Cassis soft drink

Hero Cassis is a iconic blackcurrant soft drink with a rich heritage in the Netherlands. It was first developed in 1938 by Tieleman & Dros in Leiden, using a unique fermentation process where blackcurrants from the Zeeland province are fermented (brewed) to create a distinctive flavor profile. This traditional 'brewed' method remains a core part of its branding.

While the Hero Group is headquartered in Switzerland, the Cassis brand is deeply rooted in Dutch culture and is primarily produced and distributed within the Netherlands. The product is manufactured at local bottling facilities to serve the Benelux market, maintaining its status as 'The Original' blackcurrant soda of the region.

The brand is currently owned by the Hero Group, a private international food company specializing in fruit-based products, baby food, and snacks. Hero Group acquired the brand decades ago as part of its expansion into the Dutch market, where it has since become a household name.
