The good thing about iced coffee is that it let's someone experience great coffee at home with no specialized equipment.
No grinder. Like others have said, you use all of the coffee at once, so grinding it at the store is fine.
No kettle. It's cold brew. So water temp isn't an issue.
No scale. Just buy the right amount at the store.
No machines. Just a jar and your normal filter.
Just get the right amount of some good beans, grind them at the store. Throw them in a jar with the right amount of some good water. And put it in the fridge overnight. Pull it out and run it through a filter.
