I bought some Virgil's cream soda at Merchant of Vino in Dearborn, Michigan. It was obviously expired. It tasted like it had been sitting on the shelf for a couple of years.
It's hard to tell which packages are the "fresh" ones since the store clerks usualy move the old product to the front, and put the fresh product in the back of the shelf.
I wish all food products had a "born on" date so the consumer can make a judgment call on whether or not to purchase the product.
