It's the same hand-made coffee, but it tastes cold.

Europeans are used to drinking hot coffee, but iced coffee is becoming more and more popular and has become a fashionable drink in summer.

▲ coffee is very knowledgeable, and hot and cold extraction is very different.

Thermal extraction

Coffee with ice cubes, also known as "Japanese iced coffee", is very simple: first extract the coffee with hot water, then add ice to drink, let the hot coffee cool instantly and drink immediately!

Cold extraction

Cold-extracted coffee is very different from hot-extracted coffee. Not only does it have almost no sour taste, but it also tastes warmer and more mellow, even with a slightly alcoholic flavor. Many cafes put cold-brewed coffee in specially shaped bottles and label it with a strong sense of design.

Traditional cold extraction method

Soak + filter: 12-16 hours

Coffee filter paper X5

1 liter of water

80 grams of ground coffee powder

Filter basin

1. The day before, pour the ground coffee powder into the lid container, add water and make sure the coffee powder is fully and evenly infiltrated. Close the lid, put it in the refrigerator and let stand for 12-16 hours.

two。 When you want to enjoy coffee, put filter paper in the filter basin and put it on the container containing the coffee. Pour in the cold coffee prepared the day before, filter out the coffee grounds, leave the coffee liquid, and finally add ice to drink.

Note: as with all carbohydrate liquids, sugar plus time to brew will produce fermentation (such as wine making). Coffee is roasted to produce caramelization and also contains sugar; cold-brewed coffee is placed in the refrigerator, although at a low temperature, it will also be fermented to produce the smell of alcohol. Generally speaking, the longer the time, the more obvious the taste of the wine.

The coffee cold extracted by ▲ smells of alcohol.

Ice brewed coffee

The utensils used to make cold-brew coffee look like chemical experiments, using the principle of cold extraction to extract the essence of coffee. Some people call this method cold-drip coffee.

Japanese iced coffee

Ice will melt in brewed coffee, diluting the original flavor of coffee, so it is best to use coffee with strong aroma and strong sour taste. It is also recommended to use exactly the same water as brewing coffee to make ice cubes.

▲ Japanese coffee brewing method is more convenient.

Iced coffee with unmelted ice

You can also use the classic gouache ratio of hand-brewed coffee (12-13 grams of ground coffee powder mixed with 200 milliliters of water) to make iced coffee, as long as you use "plastic ice" (water freezes in sealed plastic and doesn't flow out when melting ice). If you use plastic ice cubes, you won't have the problem of diluting your coffee, but remember to put in enough ice to cool the coffee.
