Review by cigares
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.
Review by Righrum
Just 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
Review by m8375e
Typical ECS style but the Madeira adds a nice dryness to the finish. Probably my favourite FS to date.
Review by Kevin Sorensen 🇩🇰
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.
Review by DomM
Finish is intense and on the brink of overwhelming. However gives the bottling a nice add-on. Like it.
Review by Topher
I finally committed to a bottle in my last Whisky Exchange order and have no regrets. It may be my favorite 12 year from Foursquare. Nose is fruity/nutty and perhaps vanilla. Tasting was spicy at first sip but the sweetness caught up. Very healthy balance even for Foursquare. As a bourbon fan, I am not surprised I enjoyed.
Review by Serge
Foursquare auf normalem Niveau. Schöne Vanille Noten. Wirklich nicht schlecht, auch etwas Gebäck, das sich am Gaumen entwickelt. Schön dann im Abgang. Flasche bräuchte ich jetzt aber nicht unbedingt eine davon. Dennoch ein guter Warm Up für die Village heute Abend.
Review by zabo
As you would expect, a Foursquare at a consistently high level. In my opinion, it fits in well with the previous ECS bottlings without really breaking out at the top or falling off at the bottom.
Review by Chrischi78
Kleine Reihenverkostung des RX2192, des RX7623 und des RX7158. Insgesamt landet der 7158 auf dem ersten Platz. Alle haben ein sehr ähnliches Profil. Alle sehr gefällig. Mir gelingt es aber nicht, sieht man vom ABV ab und der unterschiedlichen Intenistät echte Ausreisser in der Qualität zu benennen.
Review by Pavel Spacek
... Foursquare je destilerka z Barbadosu produkujici uzasne rumy ke kazdodennimu popijeni. Je to rum, ktery oceni zejmena rumari, kteri maji plne zuby cukru a hledaji jemny, nasladly rum plny kokosu, vanilky, cokolady a karamelu. Proste prijemne a nijak agresivni chute.
Review by crazyforgoodbooze
Das Madeira finish ist hier eher nicht von Vorteil. Der Alkohol könnte besser eingebunden sein und insgesamt dominiert eine eher störende Lack Note die vom Madeira Fass kommen könnte. Ansonsten sind hier Trockenfrüchte, Karamell und diverse Gewürze zu finden. Ist in Ordnung aber kein Highlight.
