Well, it's not white vermouth and it's not red vermouth - so it must be amber vermouth! Traditionally only available from the producer, we are lucky to have it. Apparently, this is made in the same way as the standard offerings, with the addition of cinnamon and vanilla for extra richness and depth of flavour.
This product may contain the following:
