Why is coffee centered around 2G?

Coffee is a popular drink, and in the process of making coffee, 2 grams of coffee powder is often used. This number may seem simple, but it has deep reasons and influences. This article will explore why coffee is centered around 2 grams and analyze the relevant factors behind it.

Historical background

First, let's look at the historical background. In the early days of making coffee, people usually used larger pots or bottles for brewing. However, in the early 20th century, with the advancement of technology and changes in lifestyle, people began to pursue more convenient and quick brewing methods.

So there came the filtration brewing method (such as the drip method), which requires a filter paper of a specific size and shape to filter the coffee grounds and ensure the proper contact time between the water and the coffee powder. After experimentation, it was found that using 15 grams (about 1 tablespoon) to 30 grams (about 2 tablespoons) of coffee powder in a standard size (usually 6 cups) pot can produce the best taste.

Due to its convenient measurement and universal use, people gradually accepted the standard of using 2 grams per cup of coffee. This standard is widely used around the world and has become the basic unit for making coffee.

Scientific considerations

In addition to historical background, scientific considerations are also one of the important factors in determining the 2 grams as the center. Studies have shown that in the filter brewing method, about 7 grams to 10 grams of coffee powder are needed for every 100 ml of water (i.e. 1:15 to 1:10) to achieve the ideal concentration.

In practice, 200 ml of water is usually used to brew a cup of coffee with a capacity of about 150 ml. According to the above ratio, each cup requires about 12 grams to 20 grams (i.e. 2.5 tablespoons to 4 tablespoons) of coffee powder. However, in real life, there are often different preferences and taste adjustments, so this range is usually narrowed to about 2 grams as an average.

Economic factors

In addition, economic factors also have an impact on the 2-gram range of coffee. The price of ground coffee is relatively high, and the amount of ground coffee used per cup is directly related to the cost. If too much ground coffee is used per cup, it will increase the production cost and may lead to waste.

On the other hand, if too little ground coffee is used per cup, the desired taste and strength may not be achieved. Therefore, it is very important to strike a balance between cost and quality.

Cultural habits

The last reason is cultural habits. In many countries and regions, people usually drink a cup of hot, fragrant coffee when they wake up in the morning to refresh themselves. This morning brewing method is called "breakfast brewing method", which is characterized by putting an appropriate amount of coffee (usually 2 grams) on the filter paper and slowly pouring hot water for brewing.

This method is simple, convenient, and quick, and the required amount and taste intensity can be easily controlled. Due to its universality and convenience, this brewing method has gradually become a morning habit and has become popular around the world.

in conclusion

In summary, the 2-gram standard for coffee is the result of a combination of historical background, scientific considerations, economic factors, and cultural habits. This number may seem simple, but it has deep-seated reasons and influences. Whether from the perspective of coffee making or from the perspective of consumer taste needs, 2 grams has become a generally accepted and practical standard.
