What you need:

Step 1: The coffee water ratio

The standard coffee to water ratio for a cold brew coffee is 8oz cold water to 1oz coffee grounds.

It’s up to you if you want to experiment with this ratio to suit your preferences. If you love stronger coffee, increase the ratio of coffee grounds to water.

For 5 servings, mix 24 oz of water with 4.5 oz of coarse coffee grounds.

Step 2: Choosing your coffee beans

If you enjoy drinking coffee from your local coffee house, you will likely be accustomed to the favor of Arabica coffee beans. These are the preferred coffee beans of baristas and coffee connoisseurs and are primarily used in coffee houses and shops.

The best coffee roast- Again, it all comes down to your preferred taste. The light to medium coffee roast is more acidic and fruity. On the other hand, the dark coffee roast has a more intense flavor and earthiness. 

Step 3: Coarsely grind the coffee

Coffee lovers who enjoy experimenting with different blends and brewing coffee at home are likely to have invested in a coffee grinder already. If you’re still new to the coffee club, check out our blog on choosing the best coffee grinder. This may help you decide what coffee grinder is best for you and your coffee brewing needs.

Whether you’re using a burr grinder or a blade grinder to grind your coffee beans, make sure your coffee grounds are coarse for this type of coffee. If your coffee grounds are too fine, you will over-extract the coffee beans and your cold brew coffee will have a bitter taste. On the other hand, if your coffee grounds are too coarse, you’ll end up with under-extracted flavors that are sour, acidic, and salty. We recommend using a conical burr grinder to achieve the perfect coffee grind size.

Freshly grinding your coffee beans at home will give you a much stronger and more fragrant coffee flavor. But, if you don’t already have a coffee grinder at home, you can always blitz your coffee beans using a food processor (although they will be inconsistent in size) or you can use pre-ground coffee. Bags of pre-ground coffee can be purchased from your local coffee house, grocery store, or online.

Step 4: Stirring properly 

Mix the cold water and coffee grounds together in a large jar using your preferred coffee to water ratio. Stir thoroughly using a long-handled spoon to get the mixture flowing. The grounds should be fully saturated with water.

We recommend using a mason jar or a jar with an airtight lid. Don’t worry if you don’t have this, you can always cover your jar with a small plate.

Step 5: Let it soak

The soaking time is flexible. Some advise 8 to 12 hours (basically just overnight)  in the refrigerator. Others recommend leaving your mixture in the fridge for at least 18 to 24 hours. The longer you leave it, the more intense your brew will be. For reference, Starbucks soaks their cold brew coffee for roughly 20 hours. 

If you leave it too long it can get bitter, but you can always dilute your cold brew with some extra water.

If you own a French press, you can actually make your cold brew coffee in your coffee press. Just mix it inside the French press, put the lid on top but don’t push down the plunger until it been left in the fridge overnight. Then press down on the plunger and serve.

Step 6: Strain your cold brew

Straining is essential to avoid murky, sludgy concentrate. There are various methods of straining your cold coffee brew. Select the one that works best for you.

  • Paper coffee filters
  • A clean cloth: Set your cloth on a fine-mesh sieve and pour the contents through it. make sure you put a container underneath to collect the cold brew coffee.
  • A funnel: You can use a funnel to strain the concentrate, but make sure you place a coffee filter or clean cloth over it first.
Filter Coffee Making

Choose the method that suits you best. While your cold coffee filters through, stir it gently to help the liquid strain through. You’ll need to be patient as this step can take a few minutes, especially if you’ve made a big batch.

Even if you use a French press, we recommend going through with this step to ensure your cold brew isn’t gritty.

Once your coffee is filtered, transfer the cold brew coffee into portioned-out airtight jars and store them in the refrigerator. They should last for up to 2 weeks.

TOP TIP: Don’t squeeze or press the coffee grounds during the coffee filtering process, as it may release the bitterness that affects the flavor of your cold brew coffee.

Step 7: Serve your brewed cold coffee

As you serve, remember to dilute the cold brew coffee with water according to your taste. We prefer a 1:1 ratio, meaning 1 cup of brew, to 1 cup of water, and don’t forget to add some ice cubes. You can also add some milk, oat milk, almond milk, or cashew milk to make it nice and creamy.
