Coffee lovers who often drink Italian milk coffee know that making a cup of milk coffee requires a combination of espresso and milk. For example, the latte, cappuccino, and mocha commonly found in FrontStreet Coffee are all made with different proportions of espresso and milk. Some require one part of espresso, and some require two parts. How many milliliters of Espresso is that? What is the difference between double portion and single portion? FrontStreet Coffee will answer them one by one through this article.
The difference between single and double espresso coffee
First, FrontStreet Coffee will explain the difference between a single shot of espresso and a double shot of espresso. Judging from Italian coffee making habits, one shot of espresso means 1 shot, which means 7-9g of coffee powder extracts 1 ounce of espresso. Double espresso means double espresso, which uses 14-18g of coffee powder to extract 2 ounces of espresso.
How many milliliters does it take to extract a serving of Espresso?
As mentioned before, a shot cup refers to a cup that is about 1 ounce in size, which is about 30ml in capacity. So a shot actually refers to about a 30ml cup of espresso liquid.
Nowadays, coffee shops generally use double powder bowls as standard. Single-serve powder bowls have all but disappeared. The proportion of espresso extracted is also constantly shrinking. For example, one unit of espresso used to be 7g of powder to extract 30ml of coffee liquid, but now one unit of espresso is 16g of powder to extract 32g (about 45ml) of coffee liquid.
So now a powder cake is generally called 1shot, which depends on how much coffee powder the store uses. For example, 1shot (1 part espresso) in Front Street has a liquid weight of 40g.
Latte coffee recipes
Front Street uses a Lelit espresso machine, and the extraction parameters are as follows:
Pressure: 9 bar
Temperature: 94 degrees
Time: 30 seconds
Powder to liquid ratio: 1:2
Amount of powder: 20g
Extraction concentration: 40g
Front Street uses double espresso to make latte coffee, using Front Street Sunflower Warm Yang Italian blended coffee beans. The flavor after extraction is: obvious fruit acid, lingering light berry aroma, rich wine aroma and chocolate flavor, and a pleasant aftertaste.
Milk: Full-fat fresh milk (Weiji fresh milk used in Front Street)
Temperature for whipping milk: 50-60 degrees Celsius (too low a temperature will not activate the lactose in the milk, and too high a temperature will destroy the protein in the milk, resulting in a grainy texture)
Milk foam thickness: 1 cm (milk foam thinner than 1 cm is used to make Australian white coffee, milk foam thicker than 1 cm is used to make cappuccino coffee)
Recommended hot latte coffee ratio
Front Street recommends that the ratio of coffee to milk for making latte is 1:6, 40ml espresso: 240ml hot milk. Mix the milk and espresso in a circular motion to get a hot latte. The heating of fresh milk produces a better release of the sweet molecules of lactose. After mixing evenly with the espresso, the whole latte has the sweet taste of milk, which does not steal the limelight of the espresso. On the contrary, the flavor of the espresso is better reflected in the background of the milk. The flavor of Front Street's hot latte is as follows: the aroma of whiskey, the acidity of lactose and coffee collide to create a milkshake-like sweetness, and the aftertaste is like hazelnut and other nuts.
It can be seen from the above that the espresso that FrontStreet Coffee needs to extract to make a cup of latte is a double shot of espresso, which is 40ml, while a single shot of instant coffee is 20ml, and the powder to water ratio is about 1:2. This is mainly related to the characteristics of the espresso machine, because the parameters of each espresso machine are different.
The above are the relevant answers compiled by FrontStreet Coffee on how many ml a serving of Espresso is and the difference between a double shot and a single shot of espresso.
So what coffee beans are used to make espresso?
In addition, the coffee beans used in espresso machines are also different from the coffee beans used in conventional Pour over(V60) coffee. Because espresso machines have a characteristic that amplifies the original flavor of coffee beans, sosingle origin coffeeIt is not suitable for making espresso coffee, otherwise the flavor will be difficult to guarantee. Italian blended coffee beans are a mixture of coffee beans from different origins and varieties. Generally, it is more common to mix two or three coffee beans. The purpose of blending is obvious, which is to bring together the flavors of different coffee beans to present a new flavor to achieve a more balanced effect and also serve as the store's signature.
For example, if a coffee bean is smooth but lacks aroma, another bean with rich aroma can be added to complement each other and improve the shortcomings. Another purpose of Italian blended coffee beans is to reduce costs. The traditional Italian blended beans are mixed with Robusta coffee beans, because Robusta coffee beans have a mellow flavor. Although the cupping score is not as high as that of single-origin coffee, when paired with single-origin coffee, it can provide richer and thicker crema for Italian coffee. At the same time, as the base of milk coffee, it can provide a viscous and smooth taste.
So this is one of the reasons why Italian coffee is so popular among coffee fans, because coffee berries are always a crop. Every year, the flavor of the coffee berries will be unstable due to climate and environmental problems. It may be sweeter this year and not so sweet next year. Mixing several coffee beans together can solve this problem very well, and at least make the flavor of the coffee tasted consistent every year.
