You might not have known this but to the beer connoisseur, the finest brews are best served within 30 days of their bottling. So those three year old bottles of Heineken collecting dust in your fridge garage? Yeah, slightly past their prime. But hey, at least the caps are still usable.
The MiBeerAge iOS application tells you exactly how old your beer is, accurate to the day, based on the alphanumeric code printed on the can or bottle. You can purchase the MiBeerAge app from the Apple App Store for $1.99.
