Airfix glue, here I come! Back in the mists of time, the classic Old No. 7 was my first review. Does double filtration through charcoal make this Tennessee whiskey any better? Well, the nose is less rough and almost pleasant with notes of caramelized popcorn, syrup and nail polish. Is 'diabetic' a valid descriptor? Sugary, oily and slightly minty, the taste is rather one-dimensional with fresh oak spices, the expected spiritiness and a quickly fading finish. Granted, Gentleman Jack is a step up from the basic, mass-produced Jack Daniel's - but it's a small one.
