Japanese iced coffee is the cleanest way to make cold coffee with a pour-over. You brew hot coffee straight onto ice. The ice cools the cup at once and locks in the sweet, bright flavors. It takes about three minutes, not twelve hours.
In Italy, iced coffee often means a shakerato, an espresso shaken with ice. Japanese iced coffee is the slow, gentle cousin. It suits light roasts, and it needs no machine.
What Is Japanese Iced Coffee?
It is a flash-brew method. You use half of your water as hot water. You replace the other half with ice in the server. The hot water pulls the flavor out of the coffee. The ice chills it fast, so aroma does not fade.
Cold brew, in contrast, steeps for many hours. It tastes smooth and heavy. Japanese iced coffee tastes lighter, with more fruit and more acidity. If you want the slow style, read our cold brew guide.
What You Need for Japanese Iced Coffee
- A pour-over dripper, such as a V60. You can browse V60 drippers on Amazon.
- Paper filters and a carafe or mug.
- A scale that reads in grams.
- A gooseneck kettle. See our guide to the best gooseneck kettles.
- Fresh medium-fine coffee, ideally a light or medium roast.
- Clean ice cubes.
The Japanese Iced Coffee Recipe
Roasters share many versions of this recipe. Most use a total ratio between 1:14 and 1:17, with about half of the water as ice. Here is a simple single-serve version based on those published guides.
- Coffee: 20 g, ground medium-fine.
- Hot water: 200 g, at about 200–205°F (93–96°C).
- Ice: 100 g, placed in the server.
- Time: about 2:30 to 3:00 in total.
- Heat the water. Put the ice in the carafe.
- Rinse the paper filter with hot water. Throw the rinse water away.
- Add the coffee to the dripper. Level the bed.
- Pour 40 g of water to bloom. Wait 30 to 40 seconds.
- Pour the rest in slow circles. Keep the stream gentle.
- Let it drip through. Swirl the carafe to melt the last ice.
- Pour over fresh ice and drink.
Tips to Get Better Japanese Iced Coffee
- Grind a bit finer than usual. Less water means you need a little more extraction. Our grind size guide can help you adjust.
- Taste and tweak. If it is sour, grind finer or use hotter water. If it is bitter, grind coarser.
- Use good ice. Ice made from filtered water has no odd smell.
- Choose the right beans. Light roasts with fruit or floral notes shine here.
