Up until I found this site I assumed that the designation "Charcoal Filtered", as printed on some bourbon labels, means much more than it really does.
An industry insider once described to me privately the rationale for applying that term.
Today while researching the use of 500 ml. bottles to bottle bourbon I happened upon a site that includes a picture of charcoal filtering as applied to bourbon. (Scroll past the Maker's Mark photo.) The picture matches the description I received. It's a far cry from the Lincoln County process used for Tennessee whiskey, not that that's a bad thing.
Perhaps there's a syntactical issue here. Isn't the act of filtering charcoal out of the bourbon as deserving of the term as the act of filtering bourbon through charcoal?
Does anyone know whether there are other forms of charcoal filtering as applied to bourbon?
