Which of these ''apéritifs'' is a blend of quinine for malaria-fighting since 1846?

Apéritifs (a French word) are alcoholic drinks normally served before a meal to stimulate the appetite (cf ''digestif", after a meal). An ''apéritif'' known as Dubonnet was introduced in France in 1846. This was created by a chemist Joseph Dubonnet as a means of delivering malaria-fighting quinine, where malaria is a mosquito-borne infectious disease. The medicine was a bitter brew, as such chemist Dubonnet developed a formula of herbs and spices to mask quinine's sharp flavor, and it worked so well that the recipe has remained well-guarded ever since. The French Foreign Legion soldiers of French Army made use of it in mosquito-infested Northern Africa. Dubonnet's wife and her friends were so fond of the drink and its popularity spread. It is a sweet, aromatised wine-based apéritif. The French made version is 14.8% alcohol by volume. In November 2021, Dubonnet was awarded by Queen Elizabeth II.

Dubonnet is also widely known by the advertisement slogan, ''Dubo, Dubon, Dubonnet'' meaning ''it's nice, it's good, it's Dubonnet". Queen Elizabeth II likes 66% Dubonnet and 33% gin before lunch everyday; The Queen Elizabeth The Queen Mother liked gin and Dubonnet; Nelson Rockefeller would have an occational glass of Dubonnet.
