Gentleman Jack Rare Tennessee Whiskey. Why is it a Gentleman and what makes it rare? Let’s investigate!
The main selling difference between Gentleman Jack and his dirt common cousin regular Jack Daniel’s is a second charcoal filtering. If you believe the marketing, this smooths it significantly, and is noteworthy because Gentleman Jack is the only whiskey in the world to do so. But what does charcoal filtering even do?
As howstuffworks says, charcoal is carbon, so charcoal filtering is carbon filtering. The fact that Jack Daniel’s uses sugar maple for their charcoal may suggest a context for the sweetness of the whiskey, but this is impossible. As AlcoholProfessor notes, since carbon filtering works through chemical adsorption, it is a net-loss filter – there is less stuff after the filtration, because some of it has been pulled out of solution and bonded to the carbon. This does explain the smoothness; some of the more bitter and unpleasant-tasting co-distillates in the alcohol are organic compounds, which the carbon is good at removing.
