In this text we will understand how to prepare a single cup of coffee perfectly. In addition, we will understand the importance of each of the elements during the preparation of a strained coffee.

How to make a single cup of coffee?

For every 100 ml of water (1 cup), use 10 g of ground coffee (1 tbsp).

Nothing is better than that aroma and flavor of coffee to start the day right – and whatever your method of preparation, the truth is that there are some care and tricks that can make all the difference to get the perfect cup.

Drinking coffee is one of the oldest gustatory pleasures and one of the world’s habits at the table, of those that never go out of style.

On the contrary: nowadays we have more and more fans of the habit of tasting good coffee.

Even in the days of homemade machines to make espresso and exquisite coffee, there is still room for the good old coffee strained in the cloth filter. 

The problem is that, although it is a simple drink and found everywhere on the planet, there are still basic doubts about the preparation of coffee.

Each of the elements during the preparation of coffee is important, and some of them really profoundly affect the taste of the drink, such as the temperature of the water, the choice of grinding, among others. Check out all the elements for preparing a good coffee.


Coffee water should preferably be filtered or mineral, as this will preserve the flavor and properties of the coffee powder. 

A very important point is that it cannot be boiled – we must not reach the boiling point. The ideal temperature is between 90° and 92° degrees. 

This means putting out the fire when the bubbles start to appear. Boiling water can burn the powder, affecting the taste of the coffee. In addition, the loss of oxygen changes its acidity.

Coffee powder

The quality and type of coffee grounds will suit your budget preference. The type of grinding (coarse, medium or fine) influences the filtration and the time the coffee stays in contact with the water. For cloth or paper strainers, medium to fine grinding is recommended.

Coffee powder loses its characteristics easily, so when opening a new bag, consume the product within a month. Give preference to the most recent date of manufacture at the time of purchase, as the fresher the coffee, the tastier. 

To store at home, use an airtight, dark container. Contact with light and air also causes loss of properties.


For every 100 ml of water, use 10 grams of coffee, which is equivalent to 1 tablespoon.

Coffee should be consumed within one hour of preparation. After that, the flavor begins to change. Therefore, if you are making coffee just for you, it is best to use the individual measure of 100 ml for 10 grams (a tablespoon) of coffee.


Insert the coffee in the measure indicated inside the strainer, put the water on the fire and when it is heated to a temperature of 90°, pour it slowly over the powder. At this point it is important to wet all the powder and then pour the water in a stream in the center of the strainer.

See the contact time of water with coffee according to grinding:

  • For fine grinding: up to 4 minutes
  • For medium grinding: 4 to 6 minutes
  • For coarse grinding: 6 to 9 minutes

Sugar should not be added to the water before preparation. It also changes the properties of the powder and changes the boiling point of water. Leave to sweeten in the cup. And to enjoy your coffee better, try drinking it without sugar or sweetener.

Preparation in the electric coffee maker

The coffee in the coffee maker must be made with the same measures of water and powder, using the containers indicated by the manufacturer for each of the ingredients. 

Some coffee makers prepare up to 12 cups of coffee, however the contact time of the water with the powder will be longer, which can leave the coffee bitter. If this happens, prepare fewer cups at a time.


In general, to make just one cup of coffee, we use the measure of 100 ml of water for 10 grams of coffee powder. In addition, all the elements involved in the preparation of coffee interfere with the aroma and flavor of the beverage.

Use filtered water to make the coffee, choose a good bean and, if possible, grind it right away. Don’t store your brewed coffee for too long and try to cut down on the amount of sugar and sweetener in the coffee for a complete experience.
