Foursquare Isonomy 17 Year Exceptional Cask Selection Rum

, ,

Foursquare Isonomy 17 Year Exceptional Cask Selection Rum is part of the latest highly anticipated release from the renowned Foursquare Rum Distillery.

Foursquare Isonomy 17 Year Exceptional Cask Selection Rum is a Single Blended Rum (Traditional Column and Pot Still rums) aged for 17 years in in American white oak ex-bourbon cask.  The 20th release (Mark XX) for the Exceptional Cask series, Isonomy is a big, full flavoured rum that is more complex version of the 2004 and 2005 ECS releases. The extra years in the barrel have certainly added an extra layer to indulge upon.

Aromas of coconut, vanilla, ripe peaches, pineapple, mango, sultanas, mint leaves and hot rubber fill the nose, complemented by notes of toffee, maple syrup, dates, milk chocolate, Seville orange, dry walnuts and smoked cloves throughout the palate.

This is magnificent robust rum presented at cask strength 58% alcohol by volume, without chill-filtration, at its natural colour, and free from sweeteners and other flavourings. Some time in the glass or a few drops of water opens this up nicely giving rise to more fruit and oak complexity.

Masterfully blended and bottled by fourth generation owner of Foursquare Rum Distillery, Richard L. Seale (the only son of the only son of the only son of Foursquare’s founder).

Foursquare Isonomy 17 Year Exceptional Cask Selection Rum is masterfully distilled, tropically aged and blended at the renowned Foursquare Rum Distillery on the gentle southern slopes of the St George Valley, St Philip, Barbados.

R.L. Seale is one of Barbados’ oldest trading houses, a family-owned business whose involvement in rum making extends from father-to-son since 1820. Current head distiller, Richard L. Seale, is one of the region’s most innovative distillers and blenders and has a passion for producing exceptional authentic rum from what is considered the birthplace of rum – Barbados!

The Foursquare Distillery occupies the site of a former sugar factory that dates back to 1636 and, as one of the most modern and efficient rum distilleries in the world, is designed to be both highly energy efficient and environmentally friendly. The distillery produces light rums in a three-column vacuum still and heavier rums in a modern pot still.

Foursquare Rum Distillery, with its outspoken master distiller, Richard Seale, has quickly vaulted to the forefront, having been dubbed the “Pappy of Rum” in a nod to the hysteria surrounding it.

In 1926, the Seale family began buying rum from Barbados distilleries, blending and selling it under the R. L. Seale name, eventually acquiring other brands like Doorly’s (one of the cornerstone brands of the family’s rum business to this day). Then, in the mid-1990s, Richard Seale, the fifth generation in the family business, worked with his father to renovate a shuttered sugar factory into a modern Bajan distillery. Today, the Foursquare Rum Distillery’s capacity rivals that of Mount Gay, its island neighbour.

Although Richard Seale was the first in his family to distill rather than purchase rum, he had the advantage of learning in an environment exceptionally well-versed in how great rum should taste. As both master distiller and master blender, Seale sets forth a vision of honest rum—distilled in pot and traditional column stills and unadulterated with any added sugar or sweet wines.

“In the early days […] lots of additives were in play for local brands,” he says. “When we acquired the Doorly’s brand and learned the formulas, I was very influenced by the discovery that Doorly’s was pure.”

Seale’s rise to prominence began a handful of years ago with strategic missives posted in Facebook forums, like the Ministry of Rum and Global Rum Club, calling out the widespread practice of brands spiking their rums with sweeteners. He went on to cement his notoriety (or infamy, if you ask some show organizers) by his visiting rum festivals with his digital density meter in hand, taking ABV measurements of competitors’ spirits on the fly from the show floor. (One can make a reasonably accurate assessment of how much sweetening was added post-distillation by comparing the metered versus label-stated ABV.) Enthusiasts soon followed his lead, compiling their own lists of estimated sugar levels for popular rums.

Foursquare Rum Distillery is renowned for producing premium rums from Barbados, including Doorly’s, R.L. Seale and Exceptional Cask Selection ranges including this latest release, the Foursquare Isonomy 17 Year Exceptional Cask Selection Rum and the Foursquare 2010 Exceptional Cask Selection release.
