Everything I might have learned on the rum tour I promptly forgot at the tasting session, where our Hawaiian shirt-bedecked tour guide shot generous splashes of Cruzan rum into plastic cups. Coconut, mango, guava, raspberry, some scary-looking molassesy black label concoction, cream rum… If only we hadn’t gotten there right before closing time. Though maybe that was for the best.

Cruzan rum is manufactured on a smallish plot of land on the western side of the island of St. Croix. The whole walking tour takes about fifteen minutes, from the office across a pebble-strewn lawn to an open warehouse with giant bins of fermenting alcohol, past a tower, storage facility, and trucks. The occasional chicken clucks past, and the whole operation looks more like grandpa’s moonshine still in the backyard than a legitimate rum factory which turns out something like 575,000 opaque, tropical cases of rum each year.

The fermenting house is really a raised platform built around large metal vats of water, yeast, and sugarcane in various stages of fermentation. The smell of raw alcohol sweetness, like mashed apples and burnt sugar, is overwhelming, especially in the heat.

From these vats, where thefermenting liquid spends about two days, the mash is transferred to a tall tower where it undergoes something called five-column distillation. In this process, the mash is pumped through a series of columns which remove aldehydes, esters, and other various trace compounds. This process also removes fusil oils, light oils formed during fermentation that accumulate during distillation and are often blamed for hangovers.

We say, “So we can drink as much Cruzan as we want and not have a hangover?” Our tour guide says, “I’m not saying that.”

After fermentation and distillation, the rum is cut with rainwater and placed in handcrafted wooden barrels for aging. Around 23,000 charred oak barrels of maturing rum line the shelves of an extensive aging warehouse, where the rum just sort of hangs out for at least two years – and up to twelve – thinking about who it wants to be. » Continue reading this post...
