how to date a bottle

Postby whishkeyjack » Tue Dec 03, 2013 2:48 pm

We found an old bottle of Mcguinness Cherry Whiskey in a cupboard, that has been there for over 25 years. It has no date on it, just lots of numbers and there any way of finding out how old this bottle is, and is it any good to drink?

Many times, the numbers on the bottle will tell you when the bottle itself was made. If you get the coding for the manufacturer, you can at least get an idea of about when it was bottled. This "coding" is usually on the bottom of the bottle. I only have a little experience with this and it is usually for bourbons.

Bottlers will also etch or print bottling codes on bottles. Again, once you have the ability to decode you will get the bottling time frame. Most of my experience with the latter comes from bottles from the late 1990s to current.

If the filling level is okay, then the content should not have been to much affected.
To date a bottle, you might ask whisky connoisseurs, look into old books and whisky auctions.
You can also guess the period based on the bottle shape, companies names and closure system (e.g., screw cap)
