For a delicious cup of latte, Front Street believes that the most important thing is the quality of coffee beans and milk, the ratio of coffee to milk and the extraction and fusion operation.


Point one: choose the right material


Why is latte so simple? Basically every coffee beans menu is a must-have, but the taste of latte in every store will not be exactly the same. One of the main reasons is that the materials used are different, such as milk and coffee beans.

The flavor of coffee beans can intuitively control the taste of latte coffee. The iced latte made with Front Street's premium Italian blended coffee beans shows rich flavors of nuts, chocolate, and caramel cookies, with a mellow taste and long-lasting aroma. There are also a handful of coffee beans that can bring out the sweet, rich flavor of milk in an iced latte. The Front Street Sunflower Warm Sun blended coffee beans are designed to express the rich flavors of vanilla, chocolate, cream, and cocoa.

For those who like mellow coffee, we recommend Front Street Classic Italian Blend Coffee. This is a recipe composed of three origins: Brazil, Indonesia, and Vietnam. It uses deep roasting, which can highlight the mellow aroma of coffee to the greatest extent, and also allows everyone to easily extract rich and dense coffee oil. It is very suitable for making an American style diluted with water or a latte with milk. You can buy it at the Front Street Taobao store or the Front Street Tmall flagship store. It can be seen that the choice of espresso beans has a decisive impact on the taste of latte coffee.


Friends who like sour and sweet fruity aromas recommend the Front Street Strawberry Candy espresso blended coffee beans. This is a blend of Front Street Costa Rica Tara beads, which are famous for their honey processing, and Ethiopia, the birthplace of coffee. On this basis, coupled with Colombian coffee beans, the espresso you can prepare is not only non-irritating, but also has good oil and dense texture when extracted by the coffee machine. It also has the aroma of roses, strawberry gummies, raisins, and a sweet and sour taste.

However, the choice of milk is also very important. Just full-fat fresh milk alone, there are more than 10 types commonly available on the market. Some of these milks have a strong milky taste and a thick texture, while others are light and watery. The standard for choosing milk is not to pursue thick and obvious milk flavor, but to choose one that is suitable for pairing with coffee. A strong milk flavor will mask the taste of the coffee, and a watery milk will also make the latte watery.

The second point: a reasonable ratio of milk to coffee



If the ratio of coffee to milk is wrong, it will not taste good. Too much milk will result in no coffee flavor, too little milk will accentuate the bitter taste. Therefore, making latte also requires a good balance of coffee and milk.



Front Street believes that there is no fixed ratio for latte, everything depends on the flavor expression of espresso and the matching degree of milk. But there is a rough range, 1:5 to 1:8.

The Italian coffee beans currently used by Front Street are called Sunflower Warm Sun Blend coffee beans, which are a blend of Yirgacheffe red cherries and Honduran sherry. They have a moderate bitterness and a flavor that favors sherry aroma, chocolate, vanilla cream, and brown sugar. This coffee bean is not as strong and bitter as traditional Italian beans. It is paired with milk in the right proportion and can produce a dense milk chocolate flavor. Front Street uses this coffee bean to make latte with a coffee-to-milk ratio of 1:6, 40g of espresso liquid, and 240ml of steamed milk.


The third point, specific operations


Extracting qualified espresso and creating fine and dense milk foam are the foundation for making a delicious latte. For the parameters of espresso extraction, Front Street recommends extracting 40g of coffee liquid from 20g of coffee and controlling the time to 25-30 seconds. The thickness of whipped milk is 5 minutes full and the milk is whipped to 6 minutes full. The recommended milk temperature is between 55-60 degrees.

The next step is to blend. Only when the milk and espresso are fully blended can the coffee taste consistent. If the blending is uneven, the first sip may have a strong milk taste and the next sip will have a strong coffee taste.


Good fusion is firstly about the uniform fusion of coffee oil and milk foam on the surface. This is reflected in the consistency of the color of the liquid surface, which is what we often call the "golden circle". Secondly, the coffee liquid surface is delicate and smooth, with no big bubbles.

Fusion skills


①The first step is to pass the "hardware" test! That is to say, the quality of espresso and milk foam should be good, the espresso should be rich in oil and viscous, and the milk foam should be delicate and fluid. Many times the fusion is not good because the milk foam is thickened, resulting in poor fluidity and the milk foam floating on the surface. Before fusing, shaking the coffee cup and milk jug to increase the fluidity of the liquid inside will also increase the success rate of fusing.

②The height of the vat mouth during fusion. We all know that when making latte art, the vat mouth should be lowered and close to the coffee liquid level, so that white milk foam can appear. The same principle is true. If the temperature is too low, a large amount of milk foam will float on the liquid surface, resulting in uneven fusion. If it is too high, the problems mentioned above will occur, and bubbles will appear on the liquid surface.


Generally, the distance between the cylinder mouth and the coffee liquid level is about 5 to 10 cm. Everyone's habits are different, so there are no completely fixed height and distance standards.

③ Fusion technique. The general fusion technique is to stir in one direction. Hold the coffee cup in your left hand and the raffia vat in your right hand. The two hands are staggered half a circle and perform relative circular movements. The stirring intensity of one high and one low can easily fully mix the coffee and milk. As for the size of the circle, Front Street recommends making the largest circle without hitting the wall. Be careful to slowly straighten the hand holding the coffee cup.
