I usually just let a 1:3 ratio of coffee grounds to water sit in a jar in my fridge for two days.

Treat it like a concentrate and add a little water, some ice, and maple syrup.

Easiest cold brew ever.

I start the next batch when the previous is ready to drink. Lasts a few days.

EDIT: and then I realized I was in the Coffee sub. Sorry in advance.

Going to have to disagree: cold brew made by hot coffee is generally bad.

I put coarse ground beans into a French press and then drink it the next day (18 hours later). It's the laziest method. You just make tomorrow's coffee when you are done with today's.

I will try this. All summer I have been just pulling espressos directly on ice cubes the added a touch of milk. I know its a crime but whatever, I liked it a lot and got me going.

I've tried a few different methods for making iced coffee for my wife, but by far the easiest and most reliable is to freeze some coffee in an ice cube tray, then make coffee the way you normally like it and pour it over the coffee cubes. You don't have to worry about calculating how strong to make it to offset the water in regular ice cubes. I just make a like more coffee than she drinks and the excess goes back into the freezer for the next cup.

just amazed by your effort and will haha

Make a big batch of pour over and just freeze the extra in an ice tray. Use that to ice hot coffee and you don't have to change your recipe at all (though you can still use a slightly tighter ratio since cold things taste less, which is why I've cream needs such saturated flavoring and so much sugar).

This is similar to Japanese Style Iced Coffee and is what I do every day. It's only a bit different because mine goes directly over the ice instead of sitting in the brewer. I did cold brew for a while, but I found this to be a bit more of a robust and brighter black coffee.
