The advantages of instant coffee include the speed of preparation (instant coffee dissolves quickly in hot water), the weight and volume of transport lower than beans or ground coffee, and the long shelf life - although instant coffee can spoil if not kept dry. Instant coffee also reduces cleansing because there are no coffee grounds and at least one study has found that it has a lower environmental footprint than other brewing methods.
Almost 50% of the world's green coffee is used to make instant coffee.
Preparation and Taste
Add 2 teaspoons of instant coffee to the cup, hot water over it, stir. In fact, the promising promise of quick and easy training is right. But the production of granules lasted so long and left a decent CO2 footprint.
Instant coffee is available in powder or granular form in glass and plastic jars, sachets, or boxes. The user controls the resistance of the resulting product by adding more or less powder to the water, ranging from thin "coffee water" to very strong and concentrated syrupy coffee.
Instant coffee is also convenient for making iced coffee, such as Greek frappé.
In some countries, such as Portugal, Spain, and India, instant coffee is usually mixed with hot milk instead of boiling water. In other countries, such as South Korea, instant coffee is usually mixed with cream without milk and sugar and is called a "coffee blend." It is said to have been popularized in the UK by GI during World War II, instant coffee still accounts for over 75% of the coffee bought for drinking in British homes, as opposed to well below 10% in the US and France and 1 % in Italy.
As with regular coffee, the green coffee beans themselves are roasted first to bring out the flavor and aroma. Rotary cylinders containing green beans and hot flue gases are used in most frying plants. When the grain temperature reaches 165 ° C (329 ° F), frying begins. It takes about 8-15 minutes to finish frying. After cooling, the beans are then finely ground. Grinding reduces the grains to 0.5–1.1 millimeters (0.020–0.043 in) pieces. So far, the process is generally the same as for other types of coffee.
