How to Make Japanese Style Iced Coffee

Before we leap into what you need to make this, let’s chat about what Japanese style iced coffee is (1) – and why you should care. It’s a little different to regular iced coffee (which we talk about here).

You have likely already heard of cold brew coffee (if not, read this). It uses cold water with ground coffee and is left overnight to create a concentrated and smooth, cold beverage.

Japanese-style iced coffee puts ice and hot water together with coffee to make a surprisingly bright and refreshing iced beverage.

And the reward is immediate. You can drink it right away.

There are a few tools you’ll need to do this right, but if you are a lover of great, at-home coffee, you will likely have everything in your kitchen cupboard already.

Tools needed:

  • A coffee scale or measuring cup​
  • A pour over coffee maker carafe or a larger Mason jar (475 ml or more)
  • A coffee filter that fits the pour over coffee maker or carafe
  • A kettle

1. Put The Ice Into The Jar Or Carafe

Put the cup of ice into the Mason jar or carafe.

Mason jars are handy kitchen items and are great for many different coffee drinks. You can also use them to store leftover coffee in the refrigerator, so you can make iced coffee on a whim! You could also use a carafe for this.

2. Measure Your Coffee

Don’t underestimate the importance of measuring your coffee. Measure out 30 g of coffee (1/4 cup if you don’t have a kitchen scale).

weigh your beans

For this drink, the coffee that you use matters. A darker roast is recommended for flavour.

Depending on your taste buds, it is worth considering what blend of beans might make the perfect drink for you.

3. Place The Filter Over The Mason Jar Or Carafe And Add The Coffee

With the ice in the carafe or Mason jar, set yourself up with your filter and the coffee, so you are ready to pour when the water boils.

4. Bring The Water To A Boil

You might be wondering why I am describing such a simple step in great detail. I know you know, but I need to remind you. Make sure the water is boiling before you start to pour.

There’s a science to this process – and we need water that has reached its boiling point for the perfection of chemistry to happen.

And, just for the record – using a gooseneck kettle, like one of these, to make this coffee adds a bit of joy to the experience.

5. Embrace The Bloom

Slowly and steadily, pour a bit of the water over the grounds. Just enough to cause the grounds to puff out (also called blooming – which is such an apt description, as the fragrance of the grounds wafts up after coming into contact with the water – more on that here).

Let this water drip through.

6. Do It All Over Again

Once the water has dripped through, slowly pour about half of the remaining water over the coffee grounds. Allow it to drip through and repeat with the remaining water.

Let it drain completely.

7. Remove The Filter

Remove the filter. If you made this in a Mason jar, you’re good to go. It’s a coffee maker and your glass. Modern life can be so convenient.

If it’s in a carafe, remove the filter and pour it into a tall glass.

8. Make Some Choices, Sit Back, And Enjoy

Now you’ve got some hard choices to make. You can add sugar and/or cream (there are also people who like to put some ice cream in this, which sounds delightful).

There are also rumours out there that a creamy liqueur like Baileys works well too. Mmmmmmm.

Then add in a bit more ice. Now you’re all set to sip this beautifully delicious iced coffee!

My world consists of coffee, travel, water sports and dogs...sometimes all at the same time! I spent years traveling and working in various coffee establishments, and it was on my travels that my love affair with coffee began. I've been involved in every part of the coffee production process from farm to cup and love nothing more than sharing my knowledge of my favorite morning brew with the world.
