Espresso coffee has been around for some time. It is the pride of Italians, and it is also a cultural asset that espresso coffee has brought 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 culture. Then in this next article, FrontStreet Coffee will introduce some science about the extraction ratio of Italian coffee.
Single and double espresso ratios
Espresso is 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. The single-serve concentrate 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 volume of 18-20g can also extract 55-65g of espresso liquid in the same 25-35 seconds, which is considered a suitable powder-to-water ratio, with a ratio of 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. It may also be caused by too coarse grinding, 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 sherry coffee and Yirgacheffe sun-dried red cherry coffee. They are blended into milk to highlight the rich chocolate, caramel, and tipsy flavors.
Because an espresso coffee machine has a distinctive feature that amplifies the original flavor of 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 four Italian coffee beans for everyone to choose from.
FrontStreet Coffee Sunflower Warm Blended
Flavor:Obvious fruit acidity, light berry aroma, wine aroma, rich chocolate flavor, and obvious sweet aftertaste.
Recipe:Honduran sherry: Yerga red cherry = 7:3
This front street blend is a blend of Yirgacheffe sun-dried red cherries and Honduran sherry. Front Street’s design concept for this blended bean is that it can be used in both Italian style and manual brewing. The flavor it exudes when used to make espresso has an obvious aroma of fermented wine. When you taste it, the acidity of citrus and berries emerges immediately, with the aroma of whiskey, and the aftertaste is dark chocolate.
FrontStreet Coffee Front Street Blend 100% Arabica
Flavor:Soft, slightly sour, sweet, with a nutty sweetness. The overall feeling is not too irritating, mild, and the oil is medium.
Recipe:Colombia:Brazil=3:7
This front street blend is made from Brazil and Colombia. It tastes like a light roasted grassy aroma with a slightly bitter taste. It is sweet and smooth, with a pleasant aftertaste. This is because the coffee beans from the Cymbidium producing area in Colombia have a pleasant sour taste, a mellow smell, moderate acidity, and rich sweetness that is very durable.
The coffee beans from the Cerrado region of Brazil have a pleasant sweet and bitter taste and are extremely smooth in the mouth. So the combination is absolutely perfect.
FrontStreet Coffee Front Street Commercial Blend
Flavor: The sweetness of caramel, the flavor of nuts, cocoa, and dark chocolate, a balance of sweet and sour, a little bit bitter, and a long-lasting aftertaste.
Recipe: Colombia: Brazil: Robusta = 3:6:1
This front street blend uses coffee beans from Brazil, Colombia and 10% Robusta coffee beans. The taste is classic. Front Street believes that this blend tastes rich in oil and texture, with the sweetness of caramel, and also has the flavor of nuts, cocoa, and dark chocolate. It has a balance of sweet and sour, a little bit of sweetness and bitterness, and a long-lasting aftertaste. This Front Street Commercial Blend uses the same proportion of Colombian and Brazilian coffee beans as FrontStreet Coffee's Front Street Boutique Blend 100% Arabica. The difference is that Robusta is added to provide rich oil and make the coffee taste more mellow.
FrontStreet Coffee Front Street Dark Cocoa Blend (100% Arabica)
Flavor: It has soft fruit acidity, caramel sweetness, nutty, dark chocolate flavor, smooth and sticky, but the taste is light.
Formula: Yunnan: Brazil=3:7
This blend is made from Brazil and Yunnan. Front Street believes that it tastes with soft fruit acidity and caramel sweetness, as well as nutty and dark chocolate flavors. It is smooth and sticky, but the taste is on the light side. This is because the natural conditions of Yunnan are very similar to Colombia, with high altitude, large temperature difference between day and night, mellow flavor, moderate sourness, rich and mellow taste, uniform particles, rich oil content and fruity aroma, and its quality and taste are similar to Colombian coffee. However, the taste is still slightly lighter than that of Colombia, while the coffee beans from the Cerrado region of Brazil have a pleasant sweet and bitter taste and are extremely smooth in the mouth. Therefore, the flavor of mixing these two coffee beans is also good, and this Front Street black cocoa blend (100% Arabica) coffee beans is very cost-effective and suitable for beginners in Italian style and small coffee shops.
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 with 20g of coffee powder as the base for latte coffee.
Next is frothing the milk. First we have a steam wand. Most semi-automatic coffee machines are 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 latte is done.
FrontStreet Coffee’s Recipe Latte Flavor:Smooth taste, long-lasting chocolate flavor, mixed with pleasant alcoholic taste, long-lasting aftertaste and obvious sweetness.
