What is Japanese Iced Coffee?

Before I stumbled upon the method for crafting this mouth-watering beverage, I had always thought all iced coffees were much of a muchness. How wrong I was. Japanese iced coffee is not just a drink; it's a brewing technique that results in a coffee that's bold, flavourful, and instantly chilled. This method involves brewing coffee directly over ice, which quickly cools the coffee, locking in its flavours and aroma, and giving it a delicate, refined taste that's simply unmatched.

The brilliance of Japanese iced coffee lies in its simplicity and the speed at which you can create it. Unlike cold brew which requires hours of steeping, this method delivers instant gratification along with its crystalline clarity and vibrant taste profile. Here's a quick run-down on how to make it:

Japanese Iced Coffee Recipe



  1. Grind the Coffee: Using about 15g of coffee beans, grind to a medium-fine consistency.
  2. Prepare the Ice: Fill your serving glass or jug with about 100g of ice.
  3. Heat Water: Bring about 200g of water to a boil, then let it cool slightly (just off the boil is perfect).
  4. Set Up Your Pour-over: Place the cone over your glass/jug and add the coffee filter.
  5. Brew: Begin pouring the hot water over the grounds, ensuring you saturate them evenly. The coffee will drip directly onto the ice, cooling it instantly.
  6. Stir and Serve: Once all the water has filtered through, give the coffee a quick stir to ensure it's fully cooled and evenly mixed.

This method guarantees a cup of coffee that's impossibly refreshing, with a clarity of taste that's hard to achieve through other iced coffee methods. Give it a try on a warm day, and you'll see why it's become my go-to method for a quick, delicious chill.

Benefits of Japanese Iced Coffee

When I first delved into the world of coffee brewing, Japanese iced coffee caught my attention for its remarkable balance between ease of preparation and exceptional taste. Here's why I believe it stands out:

Instant Gratification

One of the immediate benefits of Japanese iced coffee is its instant chilling process. By brewing hot coffee directly over ice, the drink cools rapidly, locking in the flavors and aromatic oils that are often lost in traditional iced coffee methods. This means I get to enjoy a refreshing and flavorful cup of coffee without the lengthy wait or dilution.

Flavor Retention

Preserving the coffee's original flavor profile is another significant advantage. The quick cooling process helps retain the nuances of the coffee, offering a taste that's both bold and nuanced. This method ensures that subtle floral and fruity notes, often lost in standard iced coffee, remain prominent and enjoyable.


The simplicity and speed of making Japanese iced coffee can't be overstated. I don't need any fancy equipment or hours of preparation. With just a few basic items already in my kitchen, I can whip up this delightful beverage in minutes. This convenience makes it my go-to method, especially on warm days when I'm craving a cool, caffeinated drink but don't want to spend too much time in the kitchen.

Reduced Acidity

For those sensitive to the acidity in hot brewed coffee, Japanese iced coffee offers a smoother alternative. The ice alters the extraction process, reducing the acidity and bitterness that can sometimes overpower hot coffee. This results in a more mellow cup, perfect for savoring on its own or with a light snack.

It's a Healthy Choice

Finally, Japanese iced coffee is a fantastic option for anyone watching their calorie intake. Since it's brewed without sugar or cream (unless added afterwards), it's a low-calorie drink that doesn't skimp on flavor. I can enjoy a guilt-free beverage that satisfies my coffee craving without derailing my health goals.

Equipment Needed for Making Japanese Iced Coffee

Making Japanese iced coffee is surprisingly straightforward, requiring just a few basic pieces of equipment. Don't worry, there's a good chance you already have most of these items in your kitchen.

First and foremost, a good quality coffee grinder is essential. Grinding your own beans just before brewing ensures that your coffee will be as fresh and flavourful as possible. If you're serious about your coffee, investing in a burr grinder can make all the difference in getting that perfect grind consistency.

You'll also need a pour-over dripper. There are many brands out there, but the Hario V60 is a popular choice among coffee enthusiasts for its heat resistance and design that enhances the extraction process. It fits snugly over most mugs and carafes, making it incredibly convenient.

Filter papers compatible with your dripper are a must to keep coffee grounds out of your drink and ensure a smooth taste. Remember to rinse the filter with hot water before use to get rid of any papery taste.

Of course, you cannot forget a kettle. A gooseneck kettle, in particular, offers control over the pouring speed and water distribution, allowing for uniform coffee extraction. However, any kettle will do in a pinch.

Lastly, you'll need a scale to measure your coffee and water accurately. Precision is key to achieving the ideal balance between the coffee's strength and its subtle flavours.

With these items at hand, you're all set to dive into the world of Japanese iced coffee. Whether you're a seasoned barista or a coffee enthusiast looking to expand your brewing techniques, the simplicity and efficiency of this method are sure to impress.

Step-by-Step Guide to Making Japanese Iced Coffee at Home

Japanese iced coffee is a refreshing brew, perfect for warmer weather or when you're looking for a quick caffeine fix with minimal bitterness. Now, I've been a fan for years, and I've perfected the art of making this beverage in the comfort of my own kitchen. Here's my straightforward guide to getting it just right, every single time.

Firstly, gather all your equipment and ingredients. You'll need:

Onto the steps:

  1. Grind your coffee beans to a medium-fine consistency. You're aiming for a texture somewhat coarser than table salt.
  2. Prep your dripper by placing it over a glass or jug filled with ice. Ensure your filter paper is snugly fitted inside the dripper.
  3. Weigh your coffee; for a single serving, 20g of coffee to 200ml of water is a solid ratio. Adjust based on the size of your brew.
  4. Boil your water and let it cool slightly to around 92-96° Celsius for the perfect extraction temperature.
  5. Bloom your coffee by pouring a little hot water over the grounds to let them "bloom" for about 30 seconds. This step releases any excess gases and ensures a more even brew.
  6. Pour the remaining water over the coffee in a slow and controlled spiral motion. The total brew time shouldn't exceed 2:30 minutes.
  7. Let the coffee drip over the ice. The ice melts, cooling the coffee instantly while diluting it to a balanced strength.

By skipping the complicated steps I've seen elsewhere and sticking to this method, I ensure my Japanese iced coffee is vibrant, refreshing, and bursting with flavour every time. With practice and a bit of experimentation with different beans and ratios, you'll soon find your perfect brew.

Tips for Perfecting Your Japanese Iced Coffee

Making a splendid cup of Japanese iced coffee might seem straightforward, but mastering the subtleties can transform a good beverage into an extraordinary one. Here are some personal tips I've gathered through trial and error, aiming to help you enhance every sip.

Selecting the Right Beans

The cornerstone of any great coffee, iced or otherwise, is the quality of the beans. For Japanese iced coffee, I recommend light to medium roast beans to highlight the nuanced flavours that chill beautifully. Experiment with single-origin beans for intriguing taste profiles that shine through the ice.

Water Temperature is Key

Achieving the perfect balance often comes down to the temperature of the water used. Aim for a water temperature between 90°C and 96°C. Water that's too hot can extract bitter compounds, especially in finer grounds, while cooler water might not extract enough flavour, leaving you with a flat-tasting brew.

Ice Matters

Not all ice is created equal. Use filtered or spring water for your ice cubes to avoid any unwanted freezer tastes transferring to your coffee. The ratio of ice to water plays a critical role too. As a starting point, aim for a 1:1 ratio of ice to hot water by weight. This ensures rapid cooling and dilution for a perfectly balanced cup.

Dial in Your Grind

The grind size for your beans is more crucial than you might think. Too coarse, and your coffee will be under-extracted and weak; too fine, and you risk bitterness. Aim for a medium-fine grind, akin to table salt's texture, as a good starting point for your experimentation.

By embracing these tips, you're well on your way to making an iced coffee that's not just refreshing, but a nuanced and flavourful journey. Remember, the beauty of Japanese iced coffee is in its simplicity and the room it offers for personal tweaks and adjustments. Explore different beans, ratios, and brewing times to find your perfect cup.


Crafting the perfect Japanese iced coffee is an art that's both simple and complex. By focusing on the quality of beans, water temperature, ice, and grind size, you're not just making a drink; you're creating an experience. It's these nuances that transform a good cup of coffee into an exceptional one. So don't be afraid to experiment and find what works best for you. Remember, the journey to the perfect iced coffee is as rewarding as the drink itself. Enjoy the process and your delicious creation.
