Japanese Iced Coffee Recipe

What is Japanese iced coffee?

Here’s how to create Japanese coffee at home:

Ingredients:

  • Coffee
  • Water
  • Ice

Equipment:

  • Kettle
  • Coffee Filters
  • Glass container
  • Coffee grinder (optional)

Steps:

1. Weigh the Ingredients

The fun part of making your own coffee is experimenting with its taste. What tastes great for others may not necessarily taste good for you. So for this step, the recommended weight of each ingredient is 25g of coffee and 200g of ice and water. However, remember that the “perfect” scale will still be up to you.

2. Boil Water and Grind Coffee Beans

Japanese iced coffee uses water that has just been boiled. For easier dilution, grind the beans into finer bits. If you purchased a pre-ground coffee, you can grind them again or skip to the next step. For a richer-tasting brew, try medium to dark roasts like the Olde Brooklyn Coffee’s Italian Dark Roast.  

3. Prepare the Filters

Rinse the Chemex or V60 filter you’ll use to remove any papery taste. Then put it over any glass container you want to use, such as a carafe.  

4. Pour Over the Filter 

Put the grounds on the filter and start pouring the freshly boiled water over it. From inward to outward, make a spiral motion to wet all the grounds evenly. Wait for around 45 seconds, so the water soaks the grounds, then pour the rest of the water while still following the same motion. 

You can now serve and enjoy your Japanese iced coffee! If you love Japanese iced coffee, you might be interested in learning about Shakerato.

Here are some tips you can use when making your Japanese iced coffee:

1. Use Large Ice Cubes

Ice cubes play a critical role in your Japanese coffee because they’ll tremendously affect the taste of your brew. Pick large ice cubes for slow melting and less dilution if you don’t want to feel like you’re racing against time.

2. Use Finer Coffee Grounds

You can keep your usual grind size for pour-overs. However, if you’re unsure what size you should aim for, you can start with a medium-size then adjust it to your liking. Finer grounds are recommended, so they easily dissolve in water.

3. Use More Coffee

If you think you need a stronger cup, then you can either lessen the water while brewing because you’ll also have ice after or just add more coffee grounds. Conversely, if the coffee is too strong, add more water while keeping the coffee ground ratio.
