Beer

I am a beer lover though I tend to lean towards non-American ones and micro-brews exceptions apart. I have often tried to figure out how often beer stays on shelves. Do they get replaced after their expiry date is over like other products? But the thing is they (at least most of them) have no expiry dates mentioned on their labels. There have been times I have opened a bottle of beer, taken a sip and realized that it did not taste anything like it was supposed to. Finally, The Wall Street Journal has cracked the code. The article tells us that the expiry date on beer bottles is a closely guarded secret with codes and what not. It also gives us an idea on how to crack the codes. I have decided that the next time I buy beer, I am going to try and decipher the code. Finally, I can utilize my economics graduate school degree for something useful and noble. Non-expired beer, here I come!
