How to Make Perfect Cold Brew Iced Coffee

As a coffee lover, there’s one thing I just didn’t get—Iced Coffee. What?! The idea left me well, cold. Coffee is supposed to be hot. Very, very hot. And then I made a life-impacting mistake. I accepted a sample of iced coffee in a popular coffee shop. It was strong, sweet, creamy and icy cold. Wow! The secret is in the cold brew coffee concentrate.

Equipment

  • Large container like a clean, new 3-gallon bucket
  • Long wooden spoon
  • Large sieve or colander
  • Cheesecloth or coffee filter

Ingredients

For 2-Gallons Coffee Concentrate (See NOTE 1)

  • 1 pound ground coffee
  • 8 quarts filtered or bottled cold water (32 cups)

For a Single Serving Iced Coffee

  • 1 ½ cups ice
  • 8 ounces cold brew coffee concentrate
  • 2 to 4 ounces milk or cream or to taste
  • 2 teaspoons sugar or to taste

Instructions

To Make Proper Coffee Concentrate

  • Into a very large container, dump one pound of ground, dark, rich coffee. Any brand will do.
  • Now pour in 8 quarts (2 gallons) of cold water.
  • Stir with a wooden spoon until all of the dry coffee is wet. Cover. Allow to steep at room temperature for at least 8 hours, longer is just fine.
  • Line a large sieve or colander with several layers of cheesecloth and pour the steeped coffee grounds through. You’ll need to prod it a bit to get all of that coffee perfectly sieved, but stick with it. You’ll end up with just shy of 8 quarts of rich, dark coffee concentrate that will be void of bitterness and very low in acidity.
  • Discard the coffee dregs; tightly cover and place the concentrate in the refrigerator.

To make a tall, cold, wonderful glass of Perfect Iced Coffee

  • Fill a 12-ounce glass―or a one-quart canning jar―with ice.
  • Pour very cold coffee concentrate over the ice until the glass or jar is about 3/4 full.
  • Add your choice of milk or cream.
  • Add the amount of sugar you need to make it as sweet as you desire. Stir to mix.

Notes

Note 1:
Not ready to commit to nearly two gallons of coffee concentrate? No problem. Scale down the proportions: 2 tablespoons of ground coffee for each cup of cold water.
Note 2:
The water you use is important: If your tap water is highly chlorinated (taste it, smell it to discover this; if it tastes good to you, use tap water here), opt for bottled or filtered water. 
Note 3:
Any ground coffee will do, but you'll be super happy if you start with dark, rich, freshly roasted coffee.
Note 4:
This coffee concentrate will keep well in the refrigerator up to 6 weeks, provided it is kept tightly covered. Enjoy!
