Step one: Get a pitcher that you can place in your fridge. No ice. Not yet.
Step two: Brew a pot of regular coffee.
Step three: let it sit until its cooled down.
Step four: pour it in the pitcher and place it in the fridge.
Step five: Let it chill out.
Why do it this way? It's easy. Wake up, brew a full pot. Take your cup out for the morning. Let it set and before you leave pour it into the pitcher. Then when you get home it's ready for you. Next morning repeat it.
Don't ice it before you pour it in the pitcher because it will water it down. You can add ice to your cup when you pour it out if you need the extra chill.
Are there other ways? Yup. But give this a try. It makes a solid cup of cold coffee to enjoy in the summer time.
