foam over the top if they are only "store cold"???

i have never figured this out in all my years.

buy some beer cold, and put them in the fridge at home, grabbing one right out of the box. take a quick swig and FIZZZZZZZZZ

that never happens with one that has been in the fridge for an hour. and NO they were not shaken up, it has something to do with the tempature. it even happend with a semi cold beer that has sat out unopened too long.

WTF causes that? i hate it

I'm no physics expert, but I would venture a guess that it has to do with the extra pressure exerted inside the can by expansion due to heat.

BTW, many people believe that buying beer cold is better than buying beer hot and will prevent "skunky" beer. This is FALSE.
Beer is subjected to many temperature extremes before it reaches your store.

Brewery: cold

Shipping: unrefrigerated

Warehouse: cold

Shipping: unrefridgerated

Store: cold or hot it's gonna taste the same when you get it home.

Most likely the "fizz" you get is from the 500 miles the beer has traveled to reach you.

The colder the beer, the more soluble the CO2. So if it is stored cold, the CO2 stays in solution better. Therefore it foams more when you open the can.

No, but warm temperatures decreases the lifespan. And too cold can make clear beers hazy.

Skunked beer is due to light (lightstruck) which affects the hops.

Higher the temperature of a liquid, the lower the solubility of a gas within it. Same for sodas and such.

I entered this thread just to watch JB's avatar dance. I'll be honest.
