How does this rum taste?
Serious Foursquare with fruity, dry punch

Beginners or anyone sensitive to 60% ABV, or drinkers who dislike light varnish/woody notes and prefer very sweet, low-strength rums.

Varnish and tropical fruit leap out of the glass. Bitter almond marzipan, infused bourbon vanilla.the alcohol is well integrated on the palate and the aromas from the nose appear in the right order.the finish is long with vanilla dessert.you shouldn't sulk your pleasure. A rum that has it all, drinkability and fruitiness. It could do with a little more dirt to deepen its aromas and put it in the big league. Even slightly better than the Empery.
Auto-translatedJust another good foursquare. This one has a nice plus in some varnish in the nose, that adds to the usual FS traits, caramel and spices, and to cask influence with red fruits and candles, traits that are there both in the nose and drinking. The cask surely adds some nice layer of complexity, nice pick
Typical ECS style but the Madeira adds a nice dryness to the finish. Probably my favourite FS to date.
Another wonderful rum from Foursquare. A bottle and sample hard to find, but if you do you have to try. The nose is fruity with oak and vanilla and in the back there's some varnish/polish. The palate is complex and lightly sweet. A full bodied rum with fruit vanilla and some peppery notes. The oak is also represented like in the nose. The finish is long with roasted oak and a hint of vanilla and chocolate. The glass the day after is even better on the nose.
