Hot knowledge! Summer teaches you to make a cold cup of coffee

It's already midsummer, still drinking hot coffee?! Don't let your taste buds get hot again, right? Make a cup of cold coffee to cheer you up.

Cold coffee is not just iced coffee made of cold water and ice! That's too casual! It is actually cold coffee brewed with cold water and after 12 hours of contact with coffee powder. It is a perfect coffee with more caffeine and less bitterness than ordinary hot coffee.

Why is cold coffee so popular in recent years? Its production principle is very simple, as long as it takes a long time to extract the essence of coffee powder with cold water, on the contrary, because the cold water is mild, it will only extract the aroma of coffee powder and will not force out the bitter taste of coffee bean impurities. the result is a cup of coffee that is stronger and sweeter. But on the other hand, because the water has been in contact with the coffee beans for a long time, it extracts more caffeine, so be careful not to drink too much!

It is not difficult to make homemade cold brewed coffee, the key lies in the ratio of coffee powder to water. It must be said that after repeated measurements, it is calculated that the average brewing coffee is about 15g per cup of water (the American measuring cup is about 240ml, a little more than one meter cup). The proportion of coffee powder is about 1:16. Many websites make cold coffee at 1:4, but the coffee made in this way is extremely concentrated! The recommended way to drink is to fill the cup with ice, pour it into iced espresso, and then season it with milk, water or sugar as you like. I've only tried the 1:16 ratio so far. It's a strong coffee (definitely stronger than a regular hot coffee), but it doesn't need to be diluted, just add a little milk and you can drink it.

Ingredients:

Cold boiled water, coffee powder. In addition, you need a cloth mesh or coffee filter paper to filter coffee powder.

Practice:

1. The proportion is easy to remember: 15g for every cup of water in the American measuring cup. Coffee powder. The American measuring cup is a little more than the rice cup (about one more scale). I make three cups, so I use 45g. Coffee powder.

If there is no Libra, you can refer to: the following rice cup (about 9 cents full) ~ 50g coffee powder

two。 Mix the coffee powder with water and mix well and soak in the refrigerator for 12 hours.

3. After 12 hours, pour the coffee into the cloth net or filter paper to filter the coffee powder, slowly wait for the coffee to flow out, do not press hard, the espresso will be finished! Please remember: this coffee is espresso. To drink American style, you must dilute it with water or milk at 1:1! If you don't dilute, you need to be responsible for it. It is said that the caffeine concentration is amazing! There are also people who do not want to add water or milk, will be diluted with full ice.

Isn't it easy! Another advantage of cold brewed coffee is that the chemical composition of the coffee does not deteriorate because it has not been brewed in hot water, so it is not easy to go bad. It is said that it can be kept in the refrigerator for up to two months. Many people put it in the refrigerator one pot at a time so that they can save time and money every morning!
