Koloa Rum Company (Hawaii) Hawaii has quietly become a powerhouse of rum production, as more and more rum producers continue to pop up across the chain of islands — a part of the world with a long history of sugar production, if not rum production. The standard-bearer for Hawaiian rum has long been Koloa, based in Kauai, which makes a range of rums from white to spiced to flavored to aged — but we’re partial to the classic “dark” rum, which has a wonderful cacao-accented personality.
