There are ways to make warm beer cold very fast but you got to be careful.
I've never understood what the fuss is all about on this selling cold beer issue. I learned this many years ago in the West Texas heat. I share it with you only on the condition that you agree to SAFELY make your beer cold in the future.
It takes seven (7) minutes, that's all folks, 7 minutes to go from room temperature to cold beer in ice water. My tests were from 78 degrees to 36 degrees. Start with a cooler with enough ice in it to cover the beer. Add just enough water to make it possible to push the beer into the ice water solution. Wait 7 minutes. Enjoy.
Disclaimers: Drink responsibly. Don't drink and drive. Remember that beer does not make you 12 feet tall or bullet proof. Consumption of beer does not make you tougher, sexier, funnier, better looking or hung better. Consumption of too much beer may make you pee too much, sleep with ugly people and possibly lay down in your own puke. Your mileage may vary.
