Activated carbon filters for Distilled alcoholic beverage

[kiwi Bruce]

I just got this from Wikipedia
Distilled alcoholic beverage purification
Activated carbon filters can be used to filter vodka and whiskey of organic impurities which can affect color, taste, and odor. Passing an organically impure vodka through an activated carbon filter at the proper flow rate will result in vodka with an identical alcohol content and significantly increased organic purity, as judged by odor and taste.
I used this to remove an overly oaked taste in a whiskey a few weeks ago, but I may have missed something very useful with this. I'll do a PDQ test this weekend and keep you posted. Kiwi Bruce
