Oaxacan Rum vs. Caribbean Rum: How the Styles Differ

Alambique Serrano is a rum from the Oaxacan highlands, made in Santa María Tlalixtac, and it is made from fresh sugar cane juice. This guide compares that style to the molasses-based rums many people know from the Caribbean.

Cane Juice, Not Molasses

Rum can legally be made from molasses, cane syrup, or cane juice. Much of the rum on the market is made from molasses, a by-product of sugar refining. Alambique Serrano's maker, the Krassel family, describes its rums as distilled from sugar cane juice and made on the steep hillsides of Santa María Tlalixtac, in what the brand calls the Oaxacan Cloud Forest.

Cane juice puts it in the same broad family as French Caribbean rhum agricole. Rhum agricole from Martinique, under its appellation rules, is made only from fresh cane juice and distilled in column stills. Alambique Serrano's catalog notes describe pot still distillation instead.

Copper Pot Still

The listing for one Alambique Serrano single cask, the "3 Anos" bottled for The Duck Inn, says it was distilled by Rommel Krassel in his custom copper alembic pot still and aged three years in an American oak ex-Mexican vino generoso cask. Pot stills are also used for some Jamaican rum, such as Hampden's.

What This Means at the Bar

In our opinion, a rum like this is one to sip: neat, in a small glass, with a few drops of water if you like. If you want to mix a daiquiri or a tiki drink, you may prefer a different bottle, because a rum with this much character can get lost in a mixed drink.

If You're Coming From Jamaica

If you like high-ester Jamaican rum such as Hampden, which we also carry, Alambique Serrano is a natural next step: also pot-still rum made in small lots, from a different place.

The Bottom Line

Oaxacan rum is a different style from most Caribbean rum, and Alambique Serrano is our favorite example of it. We carry the Single Cask #32 ($90) and Altos Esteres ($95) at our Lincoln Park bottle shop, both in stock as of October 30, 2026.
