Made with the same painstaking method as the original Noilly Prat Dry vermouth, the Noilly Prat Red (or sweet) style has a total of 30 different herbs and spices added to it which produce its deep red hues. Although the full list of herbs and spices are a closely guarded secret, we can reveal that these include saffron, cloves, cinnamon and caramel which contribute to its full and rich flavour and colour.
