I know you probably haven't heard of this one, it is a tiny rum distillery that was only opened in 2006. It is located in the grounds of a house that was built in 1658, one of only three genuine Jacobean mansions in the western hemisphere, that we visited while on vacation in Barbados in October 2011. The small distillery produces rum from fermented sugar cane juice (rather than the usual molasses - which is what is left after they remove the sugar crystals from the cane juice) and they distill in small pot still and then mature the rum in bourbon casks in their own bonded warehouse. They offer free tastings and if you want to buy a bottle they even specially engrave the bottle in the distillery while you wait. Recently found out via Twitter than you can buy the rum at Master of Malt website as well....
