A few weeks back, I contacted the distributor for Blackheart Spiced Rum with a view towards providing a review here on my website. It turned out Heaven Hill Distilleries, who own Blackheart Rum, also own Whaler’s Rum and the local importer, Diamond Estates, was hoping I would taste some Whaler’s Rum along with the Blackheart Spiced. I didn’t really know a lot about Whaler’s rum so I agreed to sample this “Hawaiian” style Rum. I say Hawaiian style, because Whaler’s takes great pride in letting everyone know that Whaler’s Rums are blended from old Hawaiian recipes. Their line-up includes three traditional rums, and five flavoured rums.
There is quite an interesting story behind the name of the Whaler’s Rums, and you can read that story as well as my review by clicking on the following excerpt:

Of course the review includes a nice recipe which particularly well suited for the Whaler’s Dark Rum called the Mandeville.
Please enjoy the review and the cocktail provided!
The Atlantico Private Cask Rum is a private label rum produced by Oliver and Oliver, for Atlantico Rum. (If you have not heard of Oliver and Oliver, I should explain that they are an independent bottler of rum operating in the Dominican Republic. They buy barreled rum from major rum producers, and age it using a solera style aging system.) Oliver and Oliver were apparently given a specific flavour profile to blend towards, and then working in conjunction with the Atlantico team, the Private Cask Rum was developed through a series of blending and tasting exercises. The result is a rum constructed to be a smooth easy to sip rum which is hoped will appeal to a wide variety of palates.
