I personally can vouch for this, as did our founder Thomas Jefferson.
Mount Gay recently released their new “Black Barrel” a NAS (no age statement) rum whose claim to fame is that it is finished in charred bourbon barrels. Listen to the marketing:
"The latest from Master Blender Allen Smith, Black Barrel is a small batch, handcrafted blend made of matured double pot distillates and aged column distillates. In a process called finishing, the blended rum is then matured for a second time in deeply charred Bourbon oak barrels. This unique process releases spicy aromas that are at once balanced, and bold."
The truth: NAS means a younger blend – Mount Gay is using the charred oak to compensate for lack of real aging (the same technique used by Phil Prichard). This is effective for Prichard, whose pot stilling and superior food grade molasses compensates with the flavor lost to the charcoal filtering. I’m not convinced this will work for Mount Gay, whose product is still largely column stilled and whose molasses is of a lesser grade. The tipoffs are these:
1. Aroma: "Complex notes of spice, toasted wood" (primary)
2. Taste: "Bold spice balanced by oaky vanilla and sweet caramel"
Let me try to explain. One of the great myths is that of "small barrel aging". The ADI wants its suckers, er customers, to believe that you can buy one of their modified and very expensive Carl stills and then magically condense 7 or 8 years of aging into 3 or 4 months? No way. This is simply not true. What you can do is to quickly take the edge off via the charring (think Jack Daniels), but at the price of LOSS of flavor and or excessive wood and "spices". Mount Gay is calling that "bold". The "sweet caramel" is a byproduct of the toasted wood sugars just below the char level and now accessible.
What you do get is smoothing and simplicity: lots - maybe too much - of wood, and caramel, but little else. I have some doubts about their vanilla claim, but as a love of Mount Gay, we are forced to review this one. MG's "trick" is to "finish" the rum in charred oak - so they can make the claim - but not so much that it overpowers the likely young juice.
It is not accidental that this possible ploy is happening now.
Bottom Line
I believe this is a compensation and a Hail Mary attempted pass to fight the predictable onslaught of the USVI subsidies. A younger NAS rum made modestly palatable through charcoal treatment. A shame, really... btw, their marketing department created a label designed to look hand numbered in a wild attempt to have us believe the small batch sales pitch...
Mount Gay's first major mistake was walking away from 300 years of history and tradition and dumping their classic bottle and labeling. This attempt to correct the error only makes it worse. Ughhh..."In recognition of its anniversary, new packaging will be introduced to the entire Mount Gay portfolio of premium rums. Black Barrel continues the brand's growth in the U.S. retailing for $29.99, and is the first rum to adorn the new packaging."
