Cold Brew Coffee For 10 Cents A Cup

Do you love cold brew coffee as much as we do? There’s nothing like sipping a delicious cup of cold brew coffee on a sunny afternoon. It’s refreshing and lacks the acidity of more common brewing methods.

Buying your own cold brew everyday is expensive, though. For example, at Starbucks, a grande cold brew is around 3$ (depending where you live). That would be around 15$ a week or 60$ a month to spend on coffee! Clearly, if you want to make cold brew, it’s better to do it at home. 

That’s why we’ve come up with this cold brew technique, which we’ll share with you here. Our technique is simple thanks to our creative filtering technique, and works out to about 10 cents per cup if you do it just like us. 

Curious how we got that number? You’ll find the breakdown at the end of this post. First, here’s the recipe:

What You’ll Need:


  • A large pitcher
  • A measuring cup
  • A spoon for stirring
  • A french press
  • Container to store coffee (like a Mason jar)
  • Tap water
  • 1-4 cups ground coffee, depending on the size of your batch
    • You’ll need a 1:6 ratio of coffee to water. Meaning, if you add six cups of water, you’ll need 1 cup of coffee.
    • We highly recommend Kirkland Signature Colombian Coffee


  1. Add coffee grounds and cold tap water to your pitcher with a 1:6 ratio of coffee to water. For every 6 cups of water you add, put 1 cup of coffee grounds until the pitcher is full.
  2. Mix well and place in fridge overnight (16-24 hours)DSC_0104
  3. The next day, use a french press to filter the coffee grounds out.DSC_0105
  4. Transfer filtered coffee concentrate to a container for storage. DSC_0111
  5. Keep in fridge until ready to be consumed, up to about a week.DSC_0114
  6. To drink, dilute with water, ice and/or milk so that about half is the cold brew concentrate and enjoy!


Cold Brew Costs:

By following our steps, you’ll yield about 2 liters of cold brew concentrate, which you’ll dilute with a 1:1 ratio of milk or water to concentrate. (Meaning for every half cup of concentrate, you’ll add a half cup of milk or water).

That means our recipe yields 4 liters of coffee, which is 32 cups. We’ll figure that for every cup, half is coffee concentrate, one quarter is milk and one quarter is ice.

Overall, the biggest cost is the coffee. That’s why picking the right coffee is important. You’ll want to pick something that’s inexpensive, but that has a good enough quality that you’ll enjoy drinking it. The best coffee for this is Kirkland Signature Colombian Coffee, which is the secret as to why our technique is so cheap. 

This coffee costs around 12$ for 1.36 kg, which is why we chose it (and because we think it’s delicious, though tastes will vary). To make our 32 cups of coffee, we used 2 cups of grounds, which is around 170 grams. So, we used around 1.50$ of coffee grounds in total, which is around 0.05$ per cup of coffee, considering the yield is 32 cups.

If we add around a quarter cup of milk to each cup that adds about 0.05$ more per cup. That brings us to our grand total of 10 cents per cup! Not bad, right?
