4X7 X.O Single Vintage Prime Rum

4X7 is a Mauritian brand whose X.O Single Vintage Prime is built from molasses rather than fresh cane juice, the more common base for rum worldwide. It draws on a single vintage and carries seven years of age in ex-bourbon casks.

Under tropical conditions seven years of barrel time delivers more than the number suggests, with faster oak extraction and deeper colour. A molasses rum of this profile typically shows warm vanilla, soft spice and gentle oak rather than the grassy snap of agricole. Bottled at 40.5%, it sits in the smooth, rounded end of aged island rum.
