Coffee is a complex product.
Most of the steps for coffee beans from planting, harvesting, washing, transporting to roasting are out of your control.
But there are two important steps that depend on you: how to grind the coffee and how to make it.
Since you have to grind coffee first, let's explore how to maximize the flavor of coffee beans and pave the way for a perfect cup of coffee.
Since you drink coffee, you need to learn how to choose good coffee beans.
1. Look
Grab a handful of coffee beans and feel whether they are solid beans with the palm of your hand.
2. Smell
Whether it is enough to smell the fragrance close to the nose.
3. Pressure
But there are two important steps that depend on you: how to grind the coffee and how to make it.
Fresh coffee beans are fresh and crisp, and the fragrance floats out when they crack.
You can put a bean into your mouth and bite it twice.
The crisp sound indicates that the beans are well preserved without dampness.
4. Color
Dark black coffee beans, the coffee brewed has a bitter taste.
Yellow coffee beans, the coffee brewed has a sour taste.
A blade grinder is needed for hand-ground coffee.
This type of grinder uses a set of rotatable blades to cut coffee beans into small pieces like a propeller.
The blade grinder is cheap, widely used and popular because of its simple operation.
However, they have certain defects.
First of all, the only way to control the degree of grinding of coffee beans is the length of grinding time.
The longer the blade rotates, the finer the coffee beans will be ground.
The problem is that some coffee beans are cut more finely than others, and the result is a mixture of coffee powder and lumps.
When you brew coffee, to maximize flavor, coffee grain size is very important, otherwise small coffee beans will be over-extracted (will make coffee sour), while large coffee beans will not be fully extracted (making coffee as insipid and boring as water).
There are many ways to brew coffee powder, two of which are the simplest.
First of all, the bubble cooking method, put the coffee powder in the cup, add hot water, let it cool while the coffee powder sinks to the bottom.
Ultra-fine coffee powder is boiled with water in a small container, usually seasoned with sugar and cardamom.
The espresso in the cup has foam on it and a layer of silted powder underneath.
The second is the pressurized method.
Espresso is made from 80 Murray 96 degrees Celsius hot water at 9 atmospheric pressure through compacted coffee pressed powder, usually only 30 milliliters per cup.
It is the strongest of the common coffee, but with a unique aroma and a touch of oil floating on the surface.
It can be drunk alone; it can also be further made into a variety of other drinks.
Because of its fast brewing speed, high concentration and low caffeine content, this method is used in many chain coffee shops or seasoned coffee.
