Opus 5 is a rhum agricole (hey, I didn't invent this - the distillers call it rhum agricole..) from the French-governed island of Reunion. This webpage http://www.dugas.fr/rhum/reunion/rivier ... etails.htm will give you more details about this rhum vieux and the distillery, which apparently dates back to 1704.
Colour: Rich amber, quite dark in colour for a rum that is not extremely old (6 - 12 years).
Nose: Sweet, with rum-raisiny notes; rich and balanced. Gives a promise of a brandy-like rum, notes of vanilla in the background. Hmm, reminds me of some very different rums (Pussers' 15 comes to mind and also the El Dorado 15).
Taste: Wow, VERY different from the nose; Much drier flavour palette hits my palate immediately, this is NOT sweet! What an astonishing difference to the bouquet. Fairly strong flavours here; some almost smoky notes, if not even a touch of tar - leathery, keeping that dryness, some burned sugar and a hint of ginger and dry cognac. Slightly burning on the palate, very robust, reminiscent of an old anejo rhum that was made in the island of Madeira, but again, more balanced.
Finish:Waxy in quality towards the end, a touch of pine sap (not unlike those found in Rockley still Barbados rums, but milder), leaving a strong flavour of burned sugar to the mouth. Pleasant.
Comments: This is a fine rum in its own right; I would recommend this to any Islay whisky fans or to anyone who thinks all rums are just sugary-sweet drinks a la Zacapa; this outlines the vast flavour profile differences one can find in the world of rum (much like in whisky). If you are looking for an easy-going rum that simply allows one to enjoy the drink without any kicks, Opus 5 may disappoint you. On the other hand if you are looking for a rum that probably goes well with a robust cigar and is spicy, a bit more demanding and thought-evoking, Opus 5 will not let you down. Definitely worth a try. I am not a huge fan of rhum agricole style, but this is one of the finer products I have tasted.
