Five methods of making Coffee from Fine Coffee

According to the contact method between water and coffee grounds, coffee brewing is classified into five methods: "brewing method","pressure method","gravity method","leaching method" and "ice brewing method". Coffee cooking

All coffee is made from ground coffee and hot water; the ground coffee is cleaned out afterwards.

The degree of fineness required depends on the cooking method chosen. Proper water temperature is crucial.

The choice of water temperature and cooking equipment, coffee beans, coffee beans roasting degree, water temperature is too low, coffee beans in the flavor can not be fully extracted; water temperature is too high, excessive extraction, taste deterioration and often bitter. If the water passes through the coffee grounds only once, the finished product will contain mainly soluble substances (including caffeine). If the water circulates through the coffee grounds several times (like a common circulating filter), the less soluble substances in the coffee beans will also enter the finished product, resulting in a bitter taste; this method is therefore not favored by enthusiasts).

A common ratio of coffee grounds to water in Western countries is 15 to 30 ml of coffee grounds (one to two tablespoons): 300 ml of water (six ounces). Coffee lovers often take the upper limit of this ratio. Please note that appropriate adjustments are made according to the thickness of the coffee grounds. Continued heating destroys the flavor of brewed coffee, and degradation also occurs at room temperature. So keeping brewed coffee warm is often a failure. However, in an oxygen-free environment, coffee can be stored at room temperature for a long time. So you can see sealed coffee on store shelves.

Many electric coffee pots are now highly automated, and some even include the function of grinding coffee beans.

According to the contact method between water and coffee grounds, coffee brewing is classified into five methods: "brewing method","pressure method","gravity method","leaching method" and "ice brewing method".

1. steeping

Do not be misled by this name. Don't boil coffee (at least not too long) or it will be too bitter.

The easiest way is to put the coffee grounds in a cup, add hot water, and let it cool while the coffee grounds sink. This is an old method that is still used in some parts of Indonesia. Be careful not to eat coffee at the bottom of the cup. The advantage of this method is that it is simple and the water temperature is just right.

Turkish coffee is an early recipe and is still used in the Middle East, North Africa, East Africa, Turkey, Greece and the Balkans. Superfine coffee grounds are boiled in water in a small container, usually with sugar and cardamom added to flavor. Espresso coffee in a cup has foam on top and a layer of powder under it.

Cowboy coffee is brewed directly in a pot with ground coffee and water. The name suggests a stopgap in crude conditions; however, some prefer it. In Finland and Sweden, where coffee consumption is highest, this is their traditional cooking method.

2. pressurization method

Espresso is made from hot water at 80 to 96 degrees Celsius at 8 to 9 atmospheres pressure through compacted coffee grounds, usually only 30 ml per cup. It is one of the strongest coffees in common, with a distinctive aroma and a touch of Crema floating on the surface. It can be drunk alone; it can also be further made into a variety of other drinks. Due to the rapid brewing, high concentration characteristics, and low caffeine content, in many chain coffee shops or flavored coffee are used in this way.

Mocha pot, also known as "Italian coffee pot", is a three-layer structure of the stove. Boiling water in the bottom layer after the vapor pressure pushed through the middle of the coffee powder into the upper layer, the coffee concentration can be compared with espresso, but no oil slick, but in the coffee spill if the pressure relief gasket, you can extract golden crema. The structure of mocha pot and automatic espresso machine is the same, but the way of water is reversed. After coffee spills about 30~40cc, remove the bottom of the pot as soon as possible, and then wipe it with a cold towel at the bottom of the pot.

3. gravity method

American coffee or filter paper method is to put coffee grounds on filter paper or metal filter, hot water from top to bottom flow is made. The strength of coffee depends on the proportion of water and the fineness of coffee grounds, but it is generally lower than espresso.

Electric circulating filters were very popular in the United States before the 1970s. It is different from the mocha pot mentioned above; hot water boils into the top layer, then flows down through the coffee grounds and back into the heating chamber; and so on several times. It is precisely because the hot water passes through the coffee grounds many times in this method that this coffee tastes bad.

4. leaching

The French press is a tall thin glass cylinder with a piston with a filter. The hot water and coffee grounds soak in the cylinder for four to seven minutes, then the piston filter presses the coffee grounds to the bottom, and the upper coffee can be poured out for drinking. This "full immersion method" is considered by many experts to be the ideal home method for brewing coffee.

Coffee bags are portable packaging for travel, which is rare at ordinary times. Malaysians use cotton bags to hold coffee grounds, immerse them in hot water, and then remove the bags from the hot water. This kind of pocket is the same as using filter paper. This is better suited to strong local coffee. The coffee in the bag can be reused.

Vacuum coffee pot (Syphon) is made up of a heating container and a funnel container connected. The connecting part is a filter on which coffee grounds are placed. The water boils in the heating vessel and enters the funnel to mix with the coffee grounds; the heating source is turned off, and the partial vacuum created by cooling the heating vessel draws the coffee back through the filter to the bottom of the funnel.

5. ice brewing

Iced coffee, also known as iced coffee, differs from the other four types of coffee by not using hot water, but using ice water slowly melted by ice cubes, slowly dripping through a filter containing coffee grounds. So it's very, very slow to have a cup of iced coffee, so it costs a lot, but it tastes great.
