I’ve tried all the “quick chill” methods I’ve heard of, but none of them work as quickly or as well as the icecream maker method. Watered down ice with some table salt. Set your unopened beer into a slurry like that, and in about 20 - 30 minutes, it’s surpremely cold. None of the “5 minutes and it’s ice cold” methods work as well or as quickly to be honest. At least not in my climate and in my experience.
I was going to type something mean about her but I’m afraid she could sense I was rude on the internet and telepathically cause my skull to explode like a hard boiled egg in a microwave.
