What company made whiskey in which the label on bottle is charcoal whiskey?

There is no widely known whiskey brand with a label that simply says "Charcoal Whiskey."

It's possible that you are thinking of one of these:

* Charcoal-filtered whiskey: Many whiskey brands use charcoal filtering as part of their production process, particularly bourbon and Tennessee whiskey. This process, sometimes called "the Lincoln County Process," helps to smooth out the whiskey and remove impurities. However, the label wouldn't usually just say "Charcoal Whiskey."

* A specific brand with a unique label: There might be a smaller distillery or independent bottler that uses a label with "Charcoal Whiskey" on it, but it would be less well-known.

To help me identify the whiskey you are thinking of, could you provide more information?

For example:

* Do you remember any other details on the label, like the brand name or location?

* What type of whiskey was it (bourbon, rye, etc.)?

* Where did you see the bottle (store, bar, online)?

With more information, I can try to help you find the specific brand you are looking for.
