Review by shazbot302
Simply magnificent. The nose, alone, will entertain for hours. The palate is rich, dark, and complex with a long finish. Back up bottles are a must.
Review by Jags
I cannot describe in details all that I taste when drinking rum. I can only assess a rum based on my own preferences. I enjoy pure rums with any additives and have tasted approximately 300 rums so far. My favorites are definitely from the Barbados profiles, especially from Foursquare Distillery, St. Nicholas Abbey and also Mount Gay. The FS Isonomy is simply the best rum I have tasted to date (from a 1 oz sample). I have since been looking to purchase this rum which is not available in Canada. On my way to New York City last week I finally got my hands on 4 bottles. Lucily I contacted the store owner and purchased those in January and asked him to set those aside for me to pick up in Mid-June. Thank you so much Norfolk Wine & Liquor in Dedham, CT!

Excellent, my second ecs foursquare & my forth over all. I was a bit dissappointed by the highly anitcipated 2008 expression. This one was by far my most pleasurable experience with any Bayan Rum I had
Review by Jacques etdom
A bewitching nose, one could spend hours on it. Intense coconut, vanilla, then a hint of pastry. The palate is a little more complex, with coconut, pastry, chocolate and fine oak. Very well-integrated alcohol. Very good length. An excellent rum.
Review by Ian Gilman
Wow! Only second Foursquare and this is really fantastic. The balance of the juice and the barrel are perfect.
Review by Kevin Sorensen 🇩🇰
This sample has been on a long trip. All the way from Barbados actually and I just couldn't wait because I was told its really good. Right off the bat, yes, a great rum and I do hope I can get a bottle. The nose is nice and well rounded with wood, minty chocolate and dried fruit trailed by vanilla, tobacco and leather. The palate is complex and well balanced with oak and dried fruit trailed by chocolate, vanilla, caramel and tobacco. The finish is long, intense and well balanced between wood, chocolate and dried fruit. Try to leave the empty glass for a while and whiff it again :-)
Review by Tim
Similar to the 2008 and therefore just as phenomenal. Very complex and balanced. Of course all the typical FS aromas are there, whether the additional years in the bourbon cask have produced an even better rum compared to the 2008 is hard to say, but what's the point. Very good overall, especially the delicious pineapple/mint note on the nose.
Review by Portman
For me, it replaces Shibboleth and 2008 as the frontrunner in the series. The length of maturation has brought both more intensity and more balance. Wonderfully fruity, vanilla, deep dried fruit, sweetness, some barrel aroma. A stunner and worth the price in my opinion.
Review by Michal S
Very pleasant aroma with notes of vanilla, chocolate and dried fruits, complex taste, long woody aftertaste. Excellent drinking.
Review by David A
Tasting of this 17-year-old Foursquare. The woody, spicy notes are evident on the nose. The richly scented molasses rum is clearly perceptible, with aromas of chocolate, caramel, vanilla and a pleasant touch of citrus. A long finish, more gourmet and less dry than Shibboleth. A very good rum to discover.
Review by Steffmaus🇩🇰
The oldest Foursquare ECS in 2023 (until the next one, slightly older is out). Very well rounded; a nose of dried fruits, and spices, with notes of chocolate, fresh fruits, leather and hints of oak. A powerful rum
Review by Christian Rudt
You pour the rum into the glass and already notice Foursquare. Vanilla, baking aromas, tropical fruit with a little coconut, the woody notes are all quickly present and extremely pleasant. Very smooth and finely distilled on the palate. The tropical fruits give a nice presence here but tend to swim along with spicy, woody impressions. Some citrus fruit now comes through and is also drawn into the nose. The finish is also very soft and balanced. Perhaps a little too much already, but it's simply great blended. The 17 years of tropical maturation are of course noticeable, so perhaps you're at the zenith of good taste, but who knows 🙂
Review by Piotr Ignasiak
Very nicely balanced, more wood and chocolate forward than Nobiliary. Aftertaste with some chocolate and mint.
Review by Fuwi
Fantastic ECS with an almost perfect balance. Very well matured, but not too dominant in the cask character, but also not too sweet but very warm and fruity, with great vanilla notes from the bourbon cask. In addition, dry, dark fruits that drift into chocolate and a wonderfully long, intense finish.
