Richland Rum is the only single-estate rum in the U.S. Richland grows their own sugarcane. They process it into cane syrup in-house. The cane syrup is then fermented and distilled all in downtown Richland, GA. It is a wonderful Agricole style rum and probably one of my favorite craft spirits.
If you're new to rum, this is a great place to start. Especially, if you come from a whiskey background.
