Rum Nation’s Demerara Solera N° 14 is quite an interesting rum. According to my correspondence with the Brand Owner, Fabio Rossi, he buys aged bulk Demerara rum (roughly four to six years) from Guyana (Demerara Distillers Limited) which has been blended with various portions from each of the Single Wooden Pot (Versailles Still) and Double Wooden Pot (Port Mourant Still).
The bulk rum purchased by Rum Nation is taken to the Nebbiolo area of Italy where it is transferred to sherry butts (PX and Oloroso) and aged for a short period of time (about 12 to 14 months). After aging, a few liters of 1997 vintage EHP (Enmore) rum is added before it is bottled. (EHP is the marque for DDL’s ancient Wooden Continuous Coffey Still.) Based upon the information as provided to me, I reckon the Demerara Solera No. 14 is approximately a five-year old rum. The recipe is rather simple and includes rum from each of the now famous ancient wooden stills from Demerara Distillers Heritage Plant. (I do believe the bulk rum used in the blend contains rums from other stills as well, but I have no information regarding the exact proportions, or exactly which other stills contribute to the Demerara Bulk Rum. )
Mr. Rossi provided me a 200 ml sample of this rum such that I would have a chance to review it here on my website. Here is an excerpt from that review:

According to the 
The Diamond Distillery sits on the East Bank of the Demerara River near Georgetown, Guyana. The Distillery was originally part of the Diamond Estate which was the last of the Sugar Plantation Estates in Guyana to produce rum, and it is now home to Demerara Distillers Limited (DDL).
A few weeks ago I received a bottle of the ‘new’ Lemon Hart Demerara 151 Rum from the Canadian Brand Owner, Mosaiq for the purpose of a review on my website. I call it the ‘new’ Lemon Hart Demerara 151 Rum because of a few changes that the rum has undergone after it was sold by Pernod Ricard to Mosaiq.
There is a place where they believe they know rum better than anywhere else. And it’s hard to ague with those folk because not only have they been smuggling and buying their rum for over three hundred years, they also happen to drink more of the stuff per capita than anyone else in North America. Where is this great rum haven, you might ask? Well, it’s not anywhere in the good old U.S. of A., and it not some tropical haven in Latin America or the Caribbean Islands. Nope, these people who drink more rum than anyone else live on a rock they call Newfoundland, which is part of the Province of Newfoundland and Labrador in the Great White North of Canada.
