I made this last night and just had a glass. It’s wonderful.
Cold-Brewed Iced Coffee
Time: 5 minutes, plus 12 hours’ resting
1/3 cup ground coffee (medium-coarse grind is best)
1. In a jar, stir together coffee and 1 1/2 cups water. Cover and let rest at room temperature overnight or 12 hours. [If you want to make a larger batch, use 2 1/4 cups of water to 1/2 cup ground coffee. - LG]
2. Strain twice through a coffee filter, a fine-mesh sieve or a sieve lined with cheesecloth. In a tall glass filled with ice, mix equal parts coffee concentrate and water, or to taste. If desired, add milk.
Yield: Two drinks.
NOTE: To make hot coffee, dilute concentrate one-to-one with water and heat in the microwave. [The hot version tastes like instant, IMHO - LG]
The background article includes this information:
Cold-brewed coffee is actually dirt simple to make at home. Online, you’ll find a wealth of forums arguing for this bean or that, bottled water over tap, the 24-hour versus the 12-hour soak. You can even buy the Toddy cold-brew coffee system for about $30.
But you can also bang it out with a Mason jar and a sieve. You just add water to coffee, stir, cover it and leave it out on the counter overnight. A quick two-step filtering the next day (strain the grounds through a sieve, and use a coffee filter to pick up silt), a dilution of the brew one-to-one with water, and you’re done. Except for the time it sits on the kitchen counter, the whole process takes about five minutes.
I was curious to see how it would taste without all the trappings. The answer is, Fantastic. My friend Carter, something of a cold-brewing savant, turned me onto another homegrown trick: freeze some of the concentrate into cubes. Matched with regular ice cubes, they melt into the same ratio as the final blend.
