How do you tell age of bottle of whiskey?

When communicating with bottle experts online, it is very important that you are able to describe all details of the bottle including height, color, mold seam, markings on body and base, etc.

It is really helpful to have clear photographs of your bottle. Take a direct side view as well as close up shots of the base and closure.

Post your description and photos on one of the antique bottle discussion forums online.
