None, but the distiller advises this is a blend of 15 rums that are aged between 5 and 10 years in ex-American oak. The oak casks come from the Jack Daniels distillery and first fill casks were used for aging the rum.
Yes, E150a is present.
Sweetness contributed to no doubt by sugar cane. Molasses wafts up and nice oak rounds things out. There is also an exotic note to this that makes me think of kitchen cooking spices like tarragon, dill and rosemary.
Robust salted caramel that is sweet but not overly so greets you. Molasses pulls up quickly with mint, cayenne pepper, cinnamon and apricot.
Drying orange rinds and more of those kitchen spices rise up. Think tarragon, rosemary and dill again! They accent the salted caramel, vanilla and orange rinds.
For the incredibly cheap price, I think you are getting good value for money. This rum is not complex, but for that price there is no burn, alcohol notes or off-putting quality.
Good stuff to sip or use as mix guilt free!
