From the folks at Eccentric Gin in Wales comes Black Batch Rum! Its name is a reference to the heavily charred American oak casks that it was rested in, though it's also been treated to the addition of orange, cinnamon, and clove, too.
Oily orange, brown sugar, a dusting of cinnamon, oak char, and vanilla.

No notable taste other than alcohol. Surprisingly harsh neat. All taste also disappears with mixer. Not much point.
