Does the espresso cup need to be warmed?

It should be said that most coffee makers still know that the coffee cups used to make coffee need to be preheated. Although there are many people who do not take this problem seriously at work, there are probably very few people who do not know that coffee cups need to be preheated.

Since espresso became popular all over the world, coffee makers began to realize that coffee cups need to be preheated in advance.

However, the strange thing is: no one seems to have thought about this question, why should the coffee cup be preheated? Under what circumstances do you need to warm up? After hearing such a warning, almost everyone accepts, acknowledges, and then executes. And why is that? It seems that no one has discussed it, and the actual implementation is even more varied and varied.

I. espresso

Once, I went to a coffee shop of a friend I met online. He asked the staff to make me an espresso. There was something wrong with me after I got this cup of coffee. Although the body of the cup was hot, I touched the upper edge of the wall with my fingers and found it was cold. So I think the cup must not be preheated, but after the coffee is filled, the cup wall is heated by coffee, so the cup wall is hot, but the upper edge of the cup wall doesn't have time to get hot, so it's still cold there.

When asked about coffee making, Italians pay special attention to emphasizing that coffee cups must be preheated before making coffee. Otherwise, the thick wall of the cup will absorb a lot of calories, resulting in a drop in the temperature of the coffee and make the taste of the coffee worse.

We need to know, what kind of cold cups can cause coffee to taste worse?

First of all, the characteristic of espresso is that if the coffee gets warmer (not cold), the taste of the coffee will get worse. This can be clearly felt when drinking coffee. At the same time, because espresso has only half a cup of a very small cup, and the walls of the coffee cup are very thick, after the coffee flows into the coffee cup, it will absorb a lot of calories by the coffee cup, causing the temperature of the coffee to become warm instead of hot. So the taste of the coffee will get worse.

So we should say that when making espresso, the preheating of the coffee cup (that is, the warm cup) is very important. If you don't warm the cup, no matter how good your espresso is, the coffee you get will not taste good. That's why warming the cup is crucial when making espresso.

Second, cappuccino coffee

Does the cappuccino need to be warmed?

Let's first take a look at how cappuccino coffee is made. The general procedure is to make an espresso in a cup, then foam it and pour it into a cup filled with espresso. So, in the first step, espresso goes into the coffee cup first. if the cup is not warm, the cup is cold, then the taste of the espresso will get worse, and it won't get better with milk. Therefore, we must warm our glasses.

The latter operation will not affect the taste of the coffee, so we will not continue to discuss it.

Latte coffee

Because different people have different procedures for making lattes, whether a latte cup needs to be warmed or not should be judged according to the actual procedure.

Traditionally in Italy, milk is added to a latte cup (Haibo cup) and then heated with steam. Make an espresso and pour it into the hot milk in the latte cup and it's done. The latte used here does not need to be preheated because the cup is already very hot in the process of heating the milk. Espresso is poured in after the milk is heated.

But there are always people who understand "Latte Art" as latte pull (do WBC contestants also understand it? ), so I always want to pull flowers when making lattes, so I reverse this order; first make an espresso in the cup, and then pour the beaten foam into the flowers. Because espresso is the first to enter the cup here, it is important to preheat the cup.

Fourth, drip coffee

This is an issue that I have mentioned, and it has caused controversy. Leave it here for the time being. After there is a certain discussion, I will make an introduction.

Conclusion: therefore, the rules are not unreasonable, they all have a certain basis. This is not a hot-headed, random decision. A reasonable and self-consistent theory should be able to explain all the relevant problems very well.
