In a nutshell: Popular crème liqueur made from wild blackberries.
The lowdown: Moroccan and Chilean wild blackberries macerated in alcohol and sugar to make this delicious crème liqueur. Among many other it's a key component of the 'Wibble', a very fruity gin based cocktail created in 1999 by Dick Bradsell at The Player in London.
Based in Dijon the company can trace its roots back to 1874. Since 1936 it's been owned by the Battault family, the fourth generation of whom are now running the business and it's now one of the few independent producers of its kind left.
While Crème de Cassis de Dijon is the liqueur at the foundation of things they've since expanded the range to encompass crème liqueurs made from many other fruits to eaux de vie, gin and other spirits. With their drinks being key ingredients to so many cocktails there won't be many bars across the world they're not seen in.
