First Impressions
Merser takes rums from four Caribbean nations — Barbados, Jamaica, the Dominican Republic, and Panama — and combines them in London, where they're married together for a further six months before bottling. This additional marriage period is key: it allows the different rum characters to integrate and harmonise in a way that freshly blended rums can't achieve.
Tasting Notes
The nose is richly aromatic. Chocolate and dried fruit lead, with spice, vanilla, and oak adding complexity. There's a gentle maritime character from the London marriage, and a rum raisin quality that ties everything together.
On the palate, the marriage shows. Chocolate depth and dried fruit are seamlessly integrated, warm spice and vanilla provide balance, and the overall impression is of a blend where the components have genuinely become something greater than the sum of their parts. Smooth and balanced at 43.1%.
The finish is medium-long, with chocolate and dried fruit fading alongside warm spice.
How to Drink It
Neat or in cocktails — the balanced character means it works in almost any context. An Old Fashioned showcases the marriage beautifully, and the four-nation blend creates an interesting talking point.
The Bottom Line
Merser Double Barrel earns a 7 — well-blended and well-married, with genuine quality from the component rums. At £36, the London marriage and four-nation blend offer good value. The extended marriage period makes a discernible difference.
