One thing not mentioned is that the colder the beer is the more carbonation it holds on to. So, if you drink your beer ice cold, prepare to belch up a storm. The super chilled beer will hold all it's carbonation and then release it all when it hits the hot temperature in your stomach. The result is a bloated belly and a long session of burping. Cellar cool beer, on the other hand, will release much of it's carbonation as the head foam dissipates and, while still being fuizzy, will be much less gassy during digestion.
