If you're looking for the expiration date on a Canada Dry Ginger Ale then you'll be interested to know that it depends on the packaging in question, and also the country you're living in.
Different countries have different branding and even rules on how food and drink safety information needs to be displayed.
With the Canada Dry Ginger Ale cans, the expiry date is usually printed on the bottom of the can:
For the plastic bottles of Ginger Ale, it's slightly different, and this expiry date is often marked on the bottle cap or on the side of the bottle cap.
In some instances, soft drink expiry dates are printed on the inside of the bottle cap. In others, the sticker label on the bottle also has these details printed on them.
You'll be happy to know that Ginger Ale has a fairly long shelf life though, so if the bottle/can is still sealed, then in most cases you should be ok to enjoy your Ginger ale. It's always best to check anyway!
