Some bottles have “pull dates” and some have “born on dates.” What do each of these dates mean? Here’s a closer look at the dates on your bottle, and how they can affect your beer.
The date you see on most beer bottles are not expiration dates but ‘pull dates,’ which are the dates retailers are instructed to pull beers off a shelf if they haven’t sold yet.
According to STLToday.com, Anheuser-Busch is changing the way they view a beer’s shelf life.
In the past, If an A-B brand beer went 110 days without selling, A-B crews would sweep into bars and restaurants, hand the retailer a check for the value of the beer then break the bottles and pour the liquid out. Now, the brewer says it has realized that the 110-day limit might not be necessary. The company says it has improved its brewing processes and packaging — using new fillers and bottle crowns, for example — that reduce the amount of oxygen in its beers.
Beer and ale, being carbonated (known as "pressure ware" in the bottle making industry), pretty much had to be contained in cylindrical heavy glass bottles since such a shape is inherently stronger than other shapes - all other things being equal, e.g., bottle size, glass thickness and quality (Tooley 1953; Glass Industry 1959).
It is also dropping its "born on" date from the small brands, although the beers will still have a code showing the packaging date.
Anheuser-Busch, now a division of Anheuser-Busch In Bev, insists that the changes occurred last summer and fall, before In Bev took over the St. By letting some small brews stay on the shelves beyond 110 days, Anheuser-Busch is confirming what many craft brewers have thought for some time -- A-B was throwing out plenty of good beer that could have stayed on the market for weeks longer.
Try to avoid any bottle at the store with dust on it, that way you can age it yourself properly if you want and ensure it will mature the right way.
Also generally speaking, unless otherwise noted, most dates on beers are pull dates, not born on dates.
