Our Review
Foursquare Isonomy 17 Year Old arrives with the kind of quiet confidence that seasoned rum drinkers appreciate. From the Foursquare stable, this aged rum from the Caribbean offers a well-considered balance of character and drinkability that places it firmly in the category of rums worth exploring. The presentation is smart without being ostentatious, and the liquid inside delivers on the promise.
The aromatics are immediately engaging. There is a warmth and depth to the nose that suggests careful maturation and attentive blending. As the rum opens up in the glass, additional layers reveal themselves — this is a spirit that rewards patience and attention. At 58% ABV, the alcohol is seamlessly integrated, serving the flavour profile rather than dominating it.
Tasting Notes
Take a sip and the palate confirms the quality signalled by the nose. There is an excellent balance here between richness and restraint, with the rum delivering genuine flavour depth without resorting to excessive sweetness or artificial intensity. The mid-palate development is particularly impressive, with flavours unfolding in a natural, unhurried progression that speaks to confident rum-making.
The finish is where this rum really distinguishes itself. Rather than fading quickly or ending abruptly, it maintains its character beautifully as the flavours gently recede. There is a warmth and satisfaction to the close that makes you want to reach for the glass again — the mark of a genuinely well-made spirit.
Value & Verdict
Priced at £195.00, this sits comfortably in the range where quality should be a given rather than a pleasant surprise. Foursquare Isonomy 17 Year Old meets that expectation and then some. This is an aged rum that works beautifully neat, shines over ice, and has enough character to anchor a premium cocktail. A worthy addition to any rum collection.
