Picket barrels are what make the magic occur in your favourite bottle of whisky. They’re additionally the supply of a long-standing drawback within the spirits trade: They leak. So much.
At Bacardi Restricted, the world’s largest privately held spirits firm, barrel leakage is an enormous headache. Contemplate the corporate’s Dewar’s blended Scotch whisky model (simply one of many dozens it owns). More often than not, Dewar’s can have over 100 warehouses stuffed with ageing barrels of whisky, 25,000 casks in each. Barrels will mature for 3 to 12 years, and based on Angus Holmes, Bacardi’s whisky class director, lots of these barrels will develop a leak in some unspecified time in the future of their life.
That’s not nice for enterprise, says Holmes. “How will we make it possible for once we come to get that cask, it’s obtained as a lot whisky in it as potential?”
Given the crucial to seek out so-called leakers earlier than a decade has come and gone—and brought all of the whisky with it—Bacardi engaged the Nationwide Manufacturing Institute Scotland. NMIS was introduced with the issue, and got here up with a stunning resolution: Why not undertake a robotic canine?
Andrew Hamilton, head of the Digital Course of Manufacturing Centre for NMIS, says the group’s first suggestion was that Dewar’s would possibly strive a Boston Dynamics Spot robotic which may roam the warehouse on the prowl for leaking barrels.
However to be a really efficient hunter, the robotic canine would want to undertake one of many precise canine household’s most well-honed abilities: an elevated sense of scent.
Vapor Trails
There are two sorts of leaks: liquid spilling or seeping out of the barrel, and lack of liquid by vapor evaporation. A barrel leaking liquid is pretty simple to establish, but when it’s dropping greater than it ought to by evaporation, that’s tougher to suss out.
Evaporation is an anticipated a part of whisky maturation, “the angel’s share” being a well-understood phenomenon that’s broadly thought of a key a part of a whisky’s evolution. In Scotland, the angels take about 2 % of a cask’s quantity annually, and whereas some enterprising distillers have tried to disclaim the angels their due by experimental strategies like overlaying barrels in plastic wrap, by and enormous distillers are joyful to present just a little whisky again to the universe as a value of doing enterprise.
