Espresso coffee has been around for a while. It is the pride of Italians, and it is also a cultural asset that espresso coffee brings to the world. Its nature is similar to the contribution of Ethiopian varieties to specialty coffee.
Espresso spread from Italy to the world and has become a status existence. Without espresso, there would be no development of espresso. Because espresso is also known as the base of coffee, such as cappuccino, latte, mocha, etc. in FrontStreet Coffee store. These coffees have always been representative of Italian coffee and are also a manifestation of a culture. Then in this next article, FrontStreet Coffee will introduce you to the extraction ratio of Italian coffee.
Single and double espresso ratios
Espresso is very important because it can directly affect the quality of a cup of coffee. The appropriate powder-to-water ratio is the key to making good espresso, so FrontStreet Coffee will briefly talk about the ratio of making espresso and how to achieve a suitable powder-to-water ratio by adjusting it.
Espresso is divided into single and double powders. Traditionally, 8-9 grams of coffee powder is used for a single portion, and 25-35 ml of espresso is extracted for 30 seconds. The ratio of a single portion of powder to water is 1:1, which is the traditional ratio and the ratio that has been used for the longest time. A single concentrated serving has a rich and fragrant taste, which is very difficult for ordinary people to eat. An important step in powder weight is weighing. Place the coffee handle on the scale and reset it to zero. Weigh about 9g of coffee powder. If you can extract 25-35g of espresso liquid in 25-35 seconds, it is considered a suitable powder-to-water ratio. A single shot of espresso is a commonly used amount of powder for cappuccino. The same proportion of milk, espresso and milk foam depends on the cup. The traditional ratio is 1:1:1
A double shot of espresso is, of course, twice the amount of a single shot. A powder amount of 18-20g can also extract 55-65g of espresso liquid in the same 25-35 seconds, which is considered an appropriate powder-to-water ratio, with the ratio being 1:1. The same operation is to reset the weighing to zero. Double espresso is the main amount used to make latte and Americano. The taste is richer and thicker than a single shot, because milk and water are added to dilute the concentration in exchange for a mellow, cottony taste. A single shot will make the coffee less flavorful, so a double shot of espresso depends on the cup capacity.
How to determine how much powder to use? The above are traditional single and double espresso powder. The coffee powder bowls have different specifications. The filling capacity of a single coffee powder bowl is as much as 14g, which is adjusted based on the baseline in the powder bowl. There is a concave powder line in the powder bowl, which is the baseline for stipulating the amount of powder. The amount of powder filled can be adjusted according to the baseline. If it exceeds the baseline, it means too much, or it may be that the grinding is too coarse, resulting in large gaps between the powder particles.
A reasonable powder-to-water ratio can be accurately achieved by weighing. The grinding degree of espresso is flour-like. The grinding scale is usually the smallest number of the Italian grinder. It can be adjusted between 1-1.5, mainly based on the amount of powder and extraction time, which is an accurate method.
What coffee beans to use for espresso
In addition, using different Italian coffee beans to make espresso will produce different coffee flavors. For example, the Italian coffee beans used in FrontStreet Coffee are a blend of Honduran coffee and Yirgacheffe sun-dried red cherry coffee, which is blended into milk to highlight the rich chocolate, caramel, and tipsy flavors.
Because an espresso coffee machine has a distinctive feature that it amplifies the original flavor of the coffee beans, and the acidity of lightly roasted coffee beans will be more prominent. If extracted with an espresso machine, the acidity will be more obvious, so it is not suitable for making espresso coffee.
So what kind of coffee beans should be used to make latte? Generally speaking, the coffee beans used to make latte coffee must be suitable for espresso machines, so coffee that is too light roasted is not suitable for making latte coffee. The darker the roasted coffee beans, the stronger the coffee flavor (caramel, bitterness) of the latte. The lighter the coffee beans, the more obvious the milky flavor of the latte will be. Therefore, the roasting degree should be selected moderately to make coffee and milk better compatible.
Then FrontStreet Coffee will recommend the following three Italian coffee beans for everyone to choose from.
"Front Street Blend 100% Arabica Coffee Beans" 75 yuan/454g: Colombian washed coffee beans + Brazilian semi-dried coffee beans, with flavors of nuts, dark chocolate, and caramel.
"Front Street Classic Blend Coffee Beans" 33 yuan/100g; Brazilian semi-sun-dried coffee beans + Indonesian Mandheling coffee beans + Vietnamese coffee beans, with rich coffee oil and mellow taste;
"Front Street Strawberry Candy Espresso" 43 yuan/100g; Costa Rican coffee beans + Panama coffee beans + Ethiopian coffee beans. It has the aroma of roses, strawberry candy and glucose. The sweet and sour fruit is prominent and has a pleasant taste.
Milk to coffee ratio in espresso
FrontStreet Coffee just mentioned above that the espresso coffee commonly seen on the market is made with different ratios of espresso and milk. So what is the ratio of espresso and milk to perfectly blend into a cup of milk coffee? Next, FrontStreet Coffee will use the example of making mocha coffee to popularize science.
Latte coffee recipes
The latte recipe used by Front Street is 1:6.5, that is, 40g of espresso mixed with 260g of steamed milk.
The espresso extraction plan used by Front Street is to extract 40g of espresso liquid in 27 seconds from 20g of coffee powder, which is used as the base for latte coffee.
The next step is to froth the milk. First of all, we have a steam wand. Most semi-automatic coffee machines will be equipped with a steam wand. Secondly, there is a container that needs to hold milk, such as a milk vat or a latte art vat (professional equipment will get twice the result with half the effort).
Finally, it comes to the choice of milk. Whether it is room temperature milk or low-temperature milk, whole milk or skimmed milk, milk can be frothed. However, if you want better texture, taste and stability of milk, Front Street still recommends using low-temperature refrigerated whole milk.
The next step is to fuse latte art, extract the espresso, steam the milk, and then you can blend it to complete the latte. Fusion is also a very important part of making latte coffee. Good fusion can make latte coffee drink smooth and comfortable, without any messy feeling. Good integration is what we often call latte art. The last cup of latte is finished.
FrontStreet Coffee's formula latte flavor: smooth taste, long-lasting chocolate flavor, mixed with pleasant wine taste, long-lasting aftertaste, and obvious sweetness.
