Recently the "Rum of the Month" over at Hamilton's commercial joint was/is the super-duper-premium Brugal 1888. If you've hung around here much you should know that the super-dupers have to promote something super-duper special to justify the super-duper price.
So what are Brugal 1888 and their faithful servant, the Preacher, saying?
Hoop, there it is! Special, super-duper horizontal aging, unlike all those ordinary, cheap vertically aged rums. And why is this special? Well, it's because it offers "more contact with the wood" - implying, of course, some kind of super-duper aging to produce their super-duper premium rum. Sure.Distilled from 100% Dominican Republic molasses in the company's continuous, two-column still, the fresh distillate is aged in used, medium-toasted, American white oak casks between five and fourteen years. After aging in American oak casks, the maturation process continues in select European first-filled sherry casks.
Unlike most of the other Brugal rums, the casks for Brugal 1888 are aged horizontally, ensuring more contact between the wood and the spirit.
Oh boy!!
Now to a skeptic like me, that's like a steaming fresh one drawing horse flies in the barnyard. Of course I had to explore this marketing claim and see if maybe, possibly this was actually true. I doubted it.
My first contact was with Chuck Cowdery, a true bourbon expert.
Now if anyone knows about barrel aging, it's Chuck Cowdery. When I posed Brugal's proposition (and my skepticism), he agreed that the choice of horizontal or vertical aging has everything to do with the efficient use of warehouse space, and barrel moving, but not with aging itself. Good stuff, but that wasn't quite definitive enough.
So I entered Phase II of the horizontal vs vertical debate.
As always, I went to the net using my trademarked and very professional research techniques and voila! Mississippi State University Agricultural Division actually publishes a page of container shapes including barrels, pyramids, spheres and the like, with plug-in formulas for volumes of differing fill levels. Go Bulldogs!
Using MSU's keen program, plus my own calculation and conversion programs, I started at what would be a minimal angel's loss of about 1%, and calculated the wood contact for three different angel share losses, and headspace...
The Results
Wood contact at 1.2% angel's loss and headspace
Horizontal: 2940 sq in.
. . vs . .
Vertical: 2913 sq. in.
Result: at a minimal angel's share loss, there is no practical difference with horizontal showing a tiny 0.9% advantage. But a 1% angel's share in the tropics is really quite unrealistic. Let's try this on for size...
Wood contact at 8.1% angel's loss and headspace
Horizontal: 2320 sq in.
. . vs . .
Vertical: 2715 sq. in.
A dramatic change. Advantage is clearly vertical storage, with a huge, 7.2% advantage! But then again, an 8.1% angel's loss and storage headspace is a bit extreme. So let's pick a realistic loss...
Wood contact at 4% angel's loss and headspace
Horizontal: 2732 sq in.
. . vs . .
Vertical: 2843 sq. in.
And yup, once again vertical storage shows a clear and substantial advantage of 4% (actually 3.92)! Interesting note: it seems for every 1% increase in angel's losses, vertical storage gains a near equal percent of wood contact.
Fascinating!
Bottom Line
The real truth is that the only time the barrels are really even is when they're both absolutely full or nearly so. At a 1% loss they are for all practical purposes the same, but after that vertical storage takes a clear lead, and keeps pulling away as the angel's share increases. If wood contact is the name of the game, the super-duper premium Brugal 1888 has it super-duper backwards. Put that in your breakfast grits.
BTW the storage position for distillers is usually determined by warehouse space, moving ease and/or use of pallets. You'll find both vertical and horizontal used, but with one important difference. The other distillers haven't tried to make a marketing claim out of it.
They know better.
By now if you don't understand that distiller hype, dutifully regurgitated by their butt kissing web shillers, should not be accepted - all hope is lost for you. Go with the program, spend your money, pretend that the hype is gospel, allow your expections to control your experience and...
Brag about your horizontally aged 1888. Delicious!
BTW, MRI studies have shown that expectations alone increase pleasurability. But that's another post...
