Varnish and tropical fruit jump out first, then the familiar Foursquare run of caramel, vanilla, toasted oak and baking spice, with dried apricot and raisin underneath. The Madeira cask adds a dry, tannic finish that a few tasters loved and one or two found a touch much. At 60% the alcohol is well woven in but pushes on the palate. A polished, complex 12-year that fans call among their favorite Foursquares.

How does Foursquare Private Cask Selection Diadem (The Whisky Exchange) taste?
From community reviews · summarized with AI
Complex, cask-strength Foursquare with a dry finish Most tasters rate this near the top of the Foursquare ECS range — fruity, spiced and complex, with a dry Madeira finish. A couple felt the varnish note and cask ran a little strong.

8,5:On the nose, nail polish and varnish, toasted oak, brown with burnt sugar, caramel, chocolate, leather, spicy with baking spices, flowery molasses, earthy with tobacco, dried fruits like raisins and apricots, bump into our nosetrils. On aeration, hints of cardboard, coffee are out, roasted nuts, caramelized, citrus, tropical fruits like coconut, hints of glue and metallic patina, molasses is herbaceous. 8,6:On the palate, the attack is sweet with toasted oak and notes like burnt sugar, caramelized, cocoa, pastry, caramel, nuts and leather, spicy with baking spices, vanilla, pepper, fruity with coconut, citrus and dried fruits, tropical, some candied. The molasses becomes candied, when the rum is well rested, dark with black tea, earthy...Nice complexity! 8,4:The finish is medium long, dry&tannic, with typical Foursquare markers lingering on.. Edit:11.7.26

The Madeira finish is rather not an advantage here. The alcohol could be better integrated and overall a rather disturbing lacquer note dominates which could come from the Madeira cask. Otherwise, there are dried fruits, caramel and various spices to be found here. It's okay but no highlight.
Review by Serge
Foursquare at a normal level. Nice vanilla notes. Really not bad, also some pastry that develops on the palate. Nice in the finish. I wouldn't necessarily need a bottle now. Still a good warm-up for the Village tonight.
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 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 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 Chrischi78
Small comparative tasting of RX2192, RX7623, and RX7158. Overall, the 7158 takes first place. All have a very similar profile. All very pleasing. I can't really identify true quality outliers apart from ABV and different intensity.
Review by Rumpalumpa
The alcohol pushes strongly here, especially on the palate. The nose has, besides varnish, a nice forest honey note. On the palate quite sweet and the tannins hit hard. Underneath the usual from Forsquare.
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 Pavel Spacek
... Foursquare is a distillery from Barbados producing amazing rums for everyday sipping. This is a rum especially appreciated by rum lovers who are fed up with sugar and looking for a gentle, sweet rum full of coconut, vanilla, chocolate and caramel. Simply pleasant and not aggressive flavors.
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 Pavel Ungr, RumRock
S 8.0 out of 10, it's a very good bottle, though not at the top of my ranking.

Read full review ›Foursquare Rum Distillery Diadem, might not be one of my top five Foursquare rums but it would likely still rank pretty highly in any top 100 I might one day produce. It's a great rum. It would certainly be the Jewel in the Crown for a lot of other distilleries!
