I got a regular events email from Jameson And I noticed the link down at the end to nutritional information. once I followed that I saw they had an ingredients list.
Irish whiskey (cereal and malt distillates), Water, Colour: plain caramel
what seems to be artificial colouring caught my eye. I know there would probably be a small difference in colour between batches and they may want to have a particular house style and consistency, but it seemed pretty odd. I’m probably naive in thinking the only colour in whiskey should come from the barrel.
