If you love an iced coffee on a hot summer's day, but hate how inconsistent the taste and texture are, then the perfect solution is to make a cold brew coffee. You’re guaranteed to get a perfectly smooth coffee every time.

It’s easy to make, especially if you get into a routine. There aren’t any complicated steps or expensive equipment, so you don’t have to be a qualified barista to pull it off. 

All you need is a strainer, coffee grinder, and a large bowl.

Prep Time: 10 minutes

Steeping Time: 12 hours

Serves: 3 Servings


  • 4 cups of water
  • 1 cup of whole coffee beans

Use high-quality low-acid dark roast coffee beans to further reduce the acidity of your coffee. You should also use a dark roast as it’s lower in acidity.


Step 1: Coarsely Grind the Coffee Beans

Use the largest setting on your grinder to grind the coffee beans. The coffee should resemble coarse cornmeal rather than the fine powder used for espresso. You should end up with just under 1 cup of coffee grounds.

Step 2: Mix the Coffee and Water

Fill the container you're using with the coffee grinds. Pour water over the top and use a long-handled spoon to stir the grinds until they’re completely submerged.

Step 3: Steep Overnight.

To keep the jar free from dust and pests, cover it with a lid or a tiny plate. Give the coffee around 12 hours to steep. If you want to put it in the fridge, you’ll need to steep it for longer (another 12 hours) to fully extract the flavors and compounds in the beans.

Step 4: Strain the Coffee

Line a small strainer with a flour sack cloth or cheesecloth. Place the strainer over a bowl or large measuring cup. Pour the coffee through the strainer.

Some Helpful Tips

Make sure the beans are ground coarsely. 

When beans are ground to a fine powder, as in the case of drip coffee, the over-infused coffee might get murky and gritty after being strained. 

If you can, use filtered water. This is better for extraction and results in a sweeter and better-defined drink.

Steep for at least 12 hours for the coffee to fully infuse the water. you can shave off a few minutes of this time, but don't be too stingy. Straining it early straining results in a weak and watery cup of coffee. 

Watch out for over-steeping. This can begin to extract some of the bitter flavors we're trying to avoid. Try not to steep for longer than around 15 hours if you’re doing it at room temperature.

Utilize coffee ice cubes to chill your cold brew. To avoid watering down your drink as the ice melts, make coffee ice cubes.

For keeping your brew at the perfect temperature, store it in closed containers or bottles and keep refrigerated.
