This was a good question from our friend Faroncinski who thought their "Solera" perhaps a "little dodgy". In a PM I replied...
Moi:
"Unfortunately Bacardi's website is long on glitz and short on detail. Distillers are known, if not famous, for misleading names. Think Zacapa 23 Anos (which implied a very old rum). When the market caught on, they amended this to "Zacapa 23" and left out the "Anos". This was simply a cheap evasion, which was done to be tecnically truthful (a very old solera), but the implication - a 23 year old rum - remained.
Now for Bacardi: Of course they know what a solera is, but is this just a name, or is there a real solera? I'm going to give this a 40/60 chance. Why?
1. None of their other rums use misleading names.
2. It would not be hard to create a very simple, two level solera, with frequent large extractions for bottling. This would technically be a solera, but certainly not a very effective one.
That's the 40% chance. The 60% chance is based - not on the label, but on their website:
Originated to commemorate the martyrs of the Virginius Affair of its namesake year BACARDI® 1873 Solera is the original, light-bodied, single barrelled sipping rum. A blend of a very rich distillate it is aged for up to three years in newly charred and carefully selected oak casks; it is blended to achieve characteristic BACARDI® smoothness.
My reasons here:
1. 1873 commemorates the Cuban Revolution against Spain, a movement promoted by Marti and by young Emilio Bacardi. Unfortunately in that year the Cuban revolutionary forces were losing, a number were captured. The "Virginius Affair" refers to an incident where captured Cubans were being executed en masse by the Spanish in Santiago, only a few blocks from the Bacardi distillery and homes
Save only for an intervention by a brave British ship captain Sir Lambdon Lorraine of the British frigate Virginius - who threatened to sink a Spanish ship if one more Cuban was executed, the slaughter would have continued. The Spanish capitulated and the "Virginius" and Lorraine became heroes to the Cubans.
My point: this date and affair had nothing to do with the solera process.
2. On their website the "Solera" is referred to as a "single barreled sipping rum" and a "blend" of rums "up to 3 years" of age. Except for the title of the rum, the word solera does not appear at all in the following description.
All said, it's close. You decide. I tend to believe that this rum is a blend, which then spends 3 years in a single barrel. What do you think?
