The bottom line, if you have some time, it takes about nine hours to get your beer or other canned drink cold in the fridge. Put it in during the morning and you can be enjoying something cold by the afternoon. But what if you want to get your drink colder, faster? The obvious solution is to put it in the freezer.
A half hour in the freezer will take the edge of a warm beer or cool a room temperature beer to decent temp. One hour in the freezer is about as far as I go unless I forget to take it out. Icy: ice crystals forming from too long in the freezer but still pourable.
It takes 10-12 minutes to chill drinks in a cooler if they are covered in ice. If they are submerged in ice water it takes just 4-6 minutes to cooler them down.
