On Reddit: When did iced coffee take off in America?
I remember my Mom drinking iced coffee in the 1970s, but it’s only in the past couple of years I’ve noticed that iced coffee seems to have become the default in hot weather, even when you’re ordering at an airport or some other large, enclosed air conditioned space. I think iced coffee is as popular as hot coffee now.
I’ve always personally preferred hot coffee, even in hot weather.
