Aisu-Kohi Coffee – A Beginner’s Guide to the Most Delicious Japanese Coffee Drink

Aisu-Kohi, or iced coffee (アイスコーヒー in Japanese), is a refreshing and invigorating beverage that originated in Japan and has grown in popularity in recent years. It is made by brewing coffee with ice, resulting in a cool and invigorating drink perfect for hot summer days.

How to prepare Aisu-Kohi coffee?

There are several methods of preparing Aisu-Kohi, but one of the most popular is the drip or pour-over method, e.g. B. with the Chemex. To prepare Aisu-Kohi using this method, you will need:

  • Freshly roasted coffee beans
  • Water
  • A Chemex coffee maker or other drip brewing system
  • A scale
  • A mill
  • Filtered water
  • Ice

Step by step instructions for preparing Aisu-Kohi coffee

First weigh the coffee beans and grind them medium fine. Fill your Chemex or other coffee maker with cold, filtered water and preheat by pouring a little water over the filter and then discarding the water. This will remove the papery taste from the filter and preheat it at the same time.

Now put the coffee in the filter and place the Chemex coffee maker on the scale. Set the scale to zero and slowly pour hot water over the coffee, starting in the center and working outward in a spiral. Aim for a brewing ratio of around 1:15, i.e. use 15 ml of water for every gram of coffee.

As the coffee brews, it drips through the filter into the Chemex or other brewing device. When the scale shows the desired weight, stop pouring. Discard the filter and coffee after draining.

Now it’s time to prepare the Aisu-Kohi. Fill a glass with ice and pour the brewed coffee over the ice. Some people add milk to their Aisu-Kohi for a creamier drink, while others prefer to keep it black and strong.

Complement your Aisu-Kohi

If you’re feeling adventurous, you can also add flavors or syrup to your Aisu-Kohi to give it a unique twist. Popular flavors include vanilla, caramel, and chocolate, but you can also get creative and try more unusual flavors like lavender or blackberry. Simply mix desired flavor into the brewed coffee before pouring over ice.

One of the great things about Aisu-Kohi is its versatility. You can use any type of coffee bean, from light and fruity Ethiopian to rich and chocolaty Brazilian. You can also experiment with different brewing methods and proportions of coffee and water to find the perfect balance of flavor and strength for your taste.

Aisu-Kohi – coffee and health

Aisu-Kohi is not only a refreshing and delicious beverage, but it also has several potential health benefits. Coffee has been shown to contain a number of antioxidants that may help reduce the risk of certain diseases and promote overall health. It can also improve cognitive functions, increase energy levels, and increase physical performance.

Like any caffeinated beverage, Aisu-Kohi should be consumed in moderation. Too much caffeine can cause side effects like insomnia, anxiety, and heart palpitations. In general, it’s recommended to limit caffeine intake to 400 milligrams per day, which is about four cups of coffee.


Aisu-Kohi is a great choice for those who want to beat the heat and recharge during the warmer months. Next time you’re in the mood for a refreshing and invigorating pick-me-up, try an Aisu-Kohi.
