This 500ml bottle of concentrated TFA Graham Cracker (Clear) multi-purpose flavouring is water soluble and contains natural and artificial flavours suspended in propylene glycol, water and ethyl alcohol. This is a nice base multi-purpose flavour that isn’t very strong but has a lasting effect. This version does not contain the caramel colour but does have a slight amber colour.
*** Note: This flavor contains ‘custard’ ingredients: Acetoin & Acetylpropionyl.
