The European Union defines three categories[1] which are: 'aromatised wine', 'aromatised wine-based drink' and 'aromatised wine-product cocktail'.
The majority of older brands come from France and Italy but there are now a range of small 'craft' producers around the world.
It is traditionally flavoured with an infusion of herbs, peels and spices, which must include some member of the Artemisia (wormwood) family.
[3][4] Notable brands include Martini and Cinzano which are commonplace around the world, and Noilly Prat and Dolin of France, Carpano and Cocchi of Italy.
These are categorised by the flavour that imparts the bitterness to the drink, usually either quinine or gentian root, or a mix of the two.
