What is Japanese ice hand coffee?

The method of making Japanese iced coffee is very simple, first put ice cubes in the coffee cup, and then use the common method to brew the coffee in hot water. ‍

Soaking coffee such as cold extract usually takes 6-12 hours to make, while Japanese iced coffee uses hot water to stimulate all the taste and aroma of the coffee in a short time, shortening the production time and helping you retain the rich and charming taste of the coffee. Coffee cools quickly after touching ice cubes, effectively locking the aroma in the coffee. ‍

The Japanese ice hand coffee made by this method is rich in flavor and takes exactly the same time as ordinary coffee. Isn't it amazing?

Bright taste and rich taste

"if made accurately, Japanese iced coffee is extremely rich in taste and bright in taste. We have tried to make it with water-washed Yega cigar, which tastes better than any cold-extracted coffee of the same type. " -- Jonathan Pascual,Taproom Coffee & Beer, Atlanta, USA

No need for professional equipment

Whether it's an Philharmonic pressure or a filter coffee machine, you can use any coffee equipment at home to brew it. The only difference is to add ice to the coffee cup in advance.

two。 Defects of Japanese Ice hand Coffee

Can only make one drink at a time.

"compared with cold coffee, which can make a whole pot at a time, Japanese iced coffee can only be made one cup at a time, and it may be troublesome to serve multiple people at the same time." -- Victor H.

It is not easy to achieve the ideal concentration.

"you have to take the melting of ice into account, so you need to adjust the degree of grinding, water and other variables, otherwise it will affect the aroma and taste of the coffee." Chad, Portland, USA

3. Brewing suggestion

You can use any existing brewing equipment to make Japanese iced coffee without spending money on professional equipment, or even retain the original brewing formula with few changes.

Therefore, there are a variety of methods and tricks for making Japanese iced coffee, but generally speaking, the following principles should be followed in making Japanese iced coffee:

Grind the coffee powder by hand.

"in principle, the coffee you make will be diluted by ice, so when making Japanese iced coffee, the amount of water should be 2 to 3 of that of regular coffee, so you need to grind the coffee powder a little bit and increase the contact area between the coffee powder and water so that more soluble substances can be dissolved in water." Tito Pena,The Wydown Coffee Bar, Washington, USA

Use chunks of ice to slow down the dilution rate

"the ice should be as large as possible, so that the melting rate of the ice will be slower and the rate of dilution will slow down." -- Lee Sill,Quills Coffee, Louisville, USA

The gouache ratio is lower (the gouache content is more).

When making Japanese iced coffee, the gouache ratio should be around 1:10, because the ice will dilute the taste of the coffee after melting. " Dustin Thomas,Steadfast Coffee, Nashville, USA
