Making a cup of latte is nothing more than adding milk to an espresso. However, this seemingly simple combination has caused many home baristas to worry. With the same ingredients and steps, why do lattes in coffee shops always taste mellow and have a long-lasting aroma? You make it like a cup of milk flavored with coffee?

Although there are more and more coffee shops opening nowadays, there are actually very few people who can really "endure hardship." The reason why latte is popular is mainly because it has more milk and less bitterness, which makes coffee more accessible.

In the broad sense, the only raw materials for latte are Italian concentrate and milk. Generally speaking, blended beans and refrigerated fresh milk are preferred. There is no fixed ratio, and most of them will be between 1:5 and 1:8. Qianjie usually likes to mix Qianjie black cocoa, extracting 38g of coffee liquor with 20g of coffee powder for 25 seconds, and then adding 240g of beaten hot fresh milk at a ratio of 1:6.

The Qianjie black cocoa blend latte made in this way can drink the strong aroma of roasted nuts and maltose. Due to the addition of a large amount of milk, the originally strong and stimulating coffee flavor becomes soft and provides a touch of sweetness. The whole taste is balanced and mellow.

Now that we already know the production steps, it is obvious that the answer to the question can only come from these key factors:

1. Insufficient concentrated aroma substances

First of all, you can remember a principle. For a successful cup of Italian concentrate, crema will have a mirror-like luster, and its thickness will be between 3 and 5mm, giving off the aroma of the coffee beans themselves. Whether it is American or latte, it will not be easily concealed.

Light roasted coffee beans extract more acid, less fat, add a large proportion of milk will easily lose the coffee flavor, become a light and sour taste. To highlight the richness of Italian concentrate, it is necessary to increase the richness of fat and enhance the caramelized aroma. Medium-and deep-baked Italian beans come out later, so they have less sour taste, more fat and higher body. The taste focuses on caramel, baked bread and cocoa aroma. It is recommended to use front street classic blending and front street commercial blending. This kind of multifunctional Italian beans can be used for both shop, home or office.

In addition to choosing the right coffee beans, freshness is also important. A packet of roasted Italian coffee beans is in the active phase of gas within 4 days, so it takes a 4 - 7 day bean cultivation period. After the end, it will enter the best taste period of about 40 - 50 days. After more than 60 days, the fat and aroma will drop linearly. Therefore, if you want to make a good latte, you must choose fresh coffee beans.

2. Milk is used "wrong"

A good latte, coffee beans and milk are equally important protagonists. If you want to make a latte as strong as a coffee shop, you should first choose whole milk because they contain more fat, protein, lactose and other substances, and have a stronger milk flavor. Only when you mix it with coffee can you achieve 1+1>2. effect.

If the quality of the milk is poor, the milk taste is light or fishy, no matter how good the coffee beans are, the latte made will be greatly discounted. (For specific milk brands, Qianjie has done a "Milk Evaluation!" I won't elaborate too much here. If you have drunk other high-quality milk that is worth recommending, you may wish to share it in the comment area.)

3. Coffee and milk do not match

Many people know that the reason why coffee and milk become the iconic combination is that they taste great together. When the latte fails to reach its ideal state, it cannot be ruled out that the taste of the two does not match.

There were guests on Qianjie who used Rose Summer SOE to match it with ice bok with double creamy flavor. The aroma of the latte made was almost completely covered up by the milk, leaving only a little fruit acid. The two had already parted ways at the entrance. This example tells us that when milk with different characteristics is paired with different coffee beans, the impact on the taste of latte is actually very obvious. This is why many coffee shops buy a lot of milk when putting new beans on shelves until debugging. Until you are in the most satisfactory state.

For example, some milk itself has a high sweetness and is paired with medium and deep roasted coffee beans with nutty flavor, such as Qianjie PWN Golden Mantelin + Bright Fresh Ranch, which can simultaneously highlight the mellow, oily aroma and clear sweetness of the latte. Feeling; Some milks have outstanding milk aroma and are extremely compatible with deep-baked Italian combinations. For example, Qianjie black cocoa basic combination + Yue fresh, the texture of the flowers is silky, which also makes the whole cup of latte stay in the mouth longer.

4. Failed to find the "golden ratio"

For a cup of latte, the extraction ratio of espresso coffee is particularly critical, because it not only determines the final concentration, but also affects the flavor of the coffee.

The formula used for extracting espresso from Qianjie is by default a powder-to-liquid ratio of 1:2. The extraction time is controlled at about 25 to 30 seconds, and the flow rate of coffee liquor is stable throughout the process. Although many friends also use a powder-to-liquid ratio of 1:2, the lattes they make have weak taste and even have some unflattering "sour taste." This is mainly because the extraction rate of coffee is not enough. There are still many substances in the powder cake that cannot be dissolved from it. It is necessary to fine adjust the grinding degree and extend the extraction time, so as to get a cup of espresso with full taste and aroma, laying a good foundation for making delicious lattes.
