Foursquare Isonomy Exceptional Cask Selection 17 Year Old Single Blended Rum (700ml)

"...one of the best ECS releases to date. Probably the best in the ex-bourbon only line up. If you can find a bottle then you won’t be disappointed." - thefatrumpirate.com

The 20th release in the ECS series and at seventeen years, it's the oldest on record. Isonomy is a 2005 pot and column still blend of rums aged in ex-bourbon casks.  The way these releases are routinely selling out, happy hunting if you don't get in quick! 58% Alc./Vol. Very limited stocks.

Other reviews... Seventeen years, that's a proper age! This is a 'single blend', so batch + column, so I suppose we shouldn't expect the same kind of knack this time. As for the name here, I would suppose the next bottling will be named 'Democracy'. We cannot wait… Colour: amber. Nose: the tropical aging starts to feel, with some thicker tar, more concentrated flower essences, whiffs of sandalwood, even incense, garam masala… It's as if at this age, the pot-still part would be winning over, although this remains delicate and 'kind of lighter'. Well, after the White, they're all going to be lighter. With water: flowers and varnish, honeysuckle, acacia... Mouth (neat): caramel, curry, allspice. With water: indeed, fudge, Frappuccino (apologies), hazelnut liqueur, even Bayley's (renewed apologies), and triple-sec. The column is having the upper hand this time. Finish: medium, easier, sweeter… And moreish. Comments: I don't think you could really beat the white LFT, but we're close. I hope they are keeping some mature 'pure' pot-still FS for later. 89 points - whiskyfun.com

...a lovely big nose which will hold your attention for quite some time and is well worth spending time with before the sip. Sipped Foursquare Isonomy is a big, more complex version of the 2004 and 2005 ECS releases. The extra years in the barrel have certainly added an extra layer. It is more rounded and fruitier. It still retains a lot of features of the 2004 and 2005 – the Bourbon esque spicy oaky notes and the big vanilla flavours but it is has also added an extra depth. It’s slightly more velvety. A lttle easier to drink even at the 58% ABV. It slips down nicely the initial entry is oaky but quickly mellows into the fruitiness and vanilla flavours. The mid palate shows an array of oak, fruit and dark chocolate notes. This leads into a long and very well rounded finish which just goes on and on....... Maybe in hindsight, it would be fun to re-review every ECS and try and rank and rate them. However, I do think that they quality has remained pretty consistent and I’d be surprised if I ever re-visited them and felt they had somehow become inferior. Maybe some of the lower ABV early releases, might suffer slightly but I tend not obsess over ABV too much. It doesn’t concern me as much as some I find. I can still enjoy 40% ABV sippers. This is one of the best ECS releases to date. Probably the best in the ex-bourbon only line up. If you can find a bottle then you won’t be disappointed. 5 stars - thefatrumpirate.com
