Smooth as Tennessee whiskey: The secret science of charcoal

KNOXVILLE, Tenn. (WVLT) – You recognize the lyric: “you’re as easy at Tennessee whiskey.” There’s numerous fact to that, and native scientists proved – for the primary time – what sippers have lengthy guessed. The supply may simply shock you.

“They’ve large impacts to nostril and taste,” Jeff Arnett of Firm Distilling stated.

Whereas there are numerous whiskey connoisseurs, Arnett is certainly one of America’s foremost consultants. Not simply on whiskey, however on how charcoal impacts the way you style it. Sure, charcoal.

“It’s eradicating issues. It’s neutralizing PH. It’s eradicating fatty acids,” Arnett stated.

He spoke about charcoal mellowing. Or filtering – the Lincoln County Course of, made well-known at Jack Daniels.

“I’m the one grasp distiller that’s ever left Jack Daniels to start out a model,” Arnett instructed WVLT.

The founding father of Townsend’s Firm Distilling gave WVLT the clinic on whiskey taste.

“The bitter style buds are in the back of your mouth and throat, so in the event you style the distillate proper off of the nonetheless, it has a really heavy aftertaste,” Arnett stated. He added that whereas corn can style candy, distilling the grain right into a bitter mash makes it intense.

“What occurs when it goes by this, what comes off the nonetheless is acidic. It’s bitter, it’s kind of heavy mouth really feel,” Arnett added.

In a College of Tennessee lab, chemistry has confirmed what distillers have lengthy recognized; charcoal mellowing “helps to make the whiskey extra easy.”

“We’re the primary crew to publish on the Lincoln County Course of since 1908,” Dr. John Munafo stated. The professor works in meals science and chemistry on the College of Tennessee.

Researchers like Dr. Munafo don’t usually ‘pattern’ the science – it’s largely smelling. And there’s quite a bit to measure with trendy expertise.

“Secure isotope dilution evaluation – with the intention to measure the flavour molecules earlier than and after,” Dr. Munafo stated.

Munafo and his taste consultants began with uncooked white canine—the stuff that comes off the nonetheless earlier than going into the charred oak barrel.

They ended up with a sweeter, smoother profile for the whiskeys. Just by utilizing that one step.

“When you do the mellowing step proper, they are typically somewhat bit lighter and sweeter than bourbon,” Arnett added.

For his or her charcoal, most distillers use sugar maple. Whiskey pioneers and Tennessee pioneers discovered it round their stills. Arnett stated the tree ‘burns clear’ with out numerous ash. Even 200 years in the past, trial and error teamed up with expertise.
