Coffee Secrets: Why Does Coffee Taste Different Every Day?

Although more and more people around us drink coffee, many people do not know enough about coffee. For example, a friend asked me yesterday: "I make coffee every day, but the taste is different. Why is that?" Because even if you use the same coffee beans, different brewing parameters will affect the taste of the coffee. This is also one of the fun of coffee. If everyone makes the same coffee, not so many people will like it. Let me show you the reason.

1. Differences in extraction methods

If you use different extraction methods every day, there will inevitably be differences in taste. For example, the taste of coffee extracted with a filter is richer, the taste of coffee extracted with an espresso machine is mellower, the concentration of coffee extracted with a French press is higher, and the taste of coffee extracted with a moka pot is bitter. Even if you use the same coffee beans, the taste of different extraction methods will be quite different.

2: The influence of grinding degree

If you use the same extraction method every day, then different grinding degrees will have a great impact on the taste. The grinding degree should be selected according to the extraction method you choose. Generally speaking, the finer the grinding degree, the larger the contact area with water, and the stronger the bitterness. The coarser the grinding degree, the smaller the contact area with water, and the lower the bitterness.

3: Effect of extraction time

When the extraction method and grinding degree are the same, different extraction times will also affect the taste of coffee. The shorter the extraction time, the lower the taste of the coffee. However, if the extraction time is too short, it is easy to cause insufficient extraction, making the taste pungent, sour, salty and other unpleasant tastes. The longer the extraction time, the stronger the bitterness of the coffee. However, too long an extraction time can easily lead to over-extraction, making the taste very bitter and astringent. The longer the extraction time, the stronger the bitterness of the coffee.

In addition, water temperature and water quality also affect the taste of coffee. Why do so many coffee lovers care so much about the parameters of brewing? It is to get a perfect cup of coffee and ensure stable production.
