Introduced in 2020, Dunderhead Rum is for all those people who just love their rums to be packing oodles of funky, punchy notes coming from the use of dunder in the fermentation stage of rum production. This practice happens in Jamaica (though it's not unique to Jamaica - similar things happen in bourbon with sour mash and in the production of baijiu), and Dunderhead Rum features high-ester Jamaican rum rich in those yummy, funky elements among its blend of Caribbean rums.
