Cold brew is the effortless way to make smooth, less acidic iced coffee at home. It requires nothing more than coarsely ground coffee, water, a jar, and a little time.
Freshly ground beans are the secret to any good coffee. If you don't have a grinder at home, a local coffee shop will grind your beans for you.
For cold brew, a coarse grind is best. The setting for French press will work well.
Put 1 cup of ground coffee into a quart jar. Add 3 cups of water and stir. Put the jar in the fridge overnight, or let it steep for longer. 18-24 hours is best.
When you're ready to enjoy, strain using a coffee filter or cheesecloth. A chemex brewer works well, but so will any Melitta, Kalita or other single brew dripper.
You will end up with a concentrated coffee. Add water, ice, any sweetener or milk you like and enjoy your iced brew!
Undiluted, cold brew will last in your fridge for up to 2 weeks, so it's a great way to save time on summer mornings when you just need to grab an iced coffee and get going.
