[cold knowledge] do you really know how to do Flat White and American coffee?

"American Coffee" English: Americano, Italian: Caff è Americano, a kind of coffee, is the most common coffee. Espresso is made by adding hot water to espresso, and it is made by an espresso machine. After the espresso is extracted, the machine continues to supply water until a complete cup of coffee. Of course, there is another kind-American trickling filter, which is commonly called Daily Cafe in coffee shops. Viagra often hear about the polarizing attitude of American style. Some people say that I only drink American coffee because it is mellow, while others say that American style is not good, and that American style is bitter and strong. For people who are addicted to coffee, American coffee is almost like blood.

Where did American coffee come from?

American coffee was born after World War II, when the Americans ended the war in Europe, many troops came to southern Europe, they could not drink strong Espresso, so they diluted it with lukewarm water, because it was the only concentration they could accept, so we can see that Espresso was not born to be loved by everyone! Because this way of drinking is mainly American soldiers, people call them American coffee. Because Americans generally make coffee casually and simply, this method quickly became popular with the popularity of American chain stores in the world.

Americano is very popular in North America, especially breakfast, and office workers with American coffee can be seen everywhere during work. American style is also very popular in other countries where coffee drinking is common. In China, most cafes also provide American coffee. According to statistics, American coffee accounts for about 15% of the total amount of Italian coffee. Through market observation, it is not difficult to find that most of those who love American style are foreigners and friends with foreign life and work experience, and most of them take out. I am glad to see that these friends have gradually turned coffee into a necessity of life.

The Soul of American style-espresso (Espresso)

When many people first come into contact with American style, they will be surprised that espresso can be sold as American coffee as soon as it is put into the water. In fact, espresso was invented and developed in Italy, which began in the early 20th century, but until the mid-1940s, it was a drink made separately through vapor pressure. It was only after the invention of the commercial coffee machine that espresso was transformed into the drink known today. The process of making Double Espresso is that the coffee machine uses high temperature and high pressure water to extract the coffee liquid of 45--60ml in 20-30 seconds.

It is such a strong liquid that not only tests the coffee beans, but also tests the barista's extraction skills. if the extraction time is tens of seconds, if the extraction is stopped prematurely, the concentration will become very sour and cannot be imported. A few seconds later, it will feel concentrated into water, and even a bitter and smoky bad taste, only the right time can make a cup concentrated rich and complex, or round, or bright. Or calm, different varieties and roasted coffee beans will bring different taste, but even if you make a cup of delicious concentrate that baristas like to talk about, there will still be guests who will not pay the bill. Of course, there will still be many people who can't accept the strong stimulation of concentration, but can't resist the temptation of coffee, so they choose the American style. After being diluted with water, the concentrated sour, sweet and bitter will be diluted, become more pleasing, and be able to drink for a while.

Long Black and Lungo

Two brothers of the American style, they and the American style are both a mixture of espresso and water, so what's the difference?

The difference between ▼ method and flavor

Because the solubility of various flavor components in coffee is different from that of water, shortening or prolonging the extraction time of Espresso, the flavor components of coffee in the extraction solution are also different. therefore, the taste of all kinds of coffee is different, not only the difference of "light" or "heavy" taste.

Americano is to add espresso first and then water. The grease (crema) on Americano will be washed away by hot water.

For Long Black, water is added first and then Espresso is extracted. Because the grease on the Long Black is poured later, you will see more grease on the surface of the coffee, and the grease will last longer because it is not affected by external force. The insoluble substances in oil (crema) are the result of emulsification under high pressure. And the oil contains carbon dioxide, containing many flavors and aromas. At the same time, because of its insoluble ingredients, this layer of oil forms a film on the coating of our tongue when drinking it. This film will give us a lasting aftertaste while weakening the sensitivity to bitterness. So Americano will be a little more painful than Long Black.

▼, what is Lungo coffee?

Lungo is to speed up the flow rate of espresso by changing the scale of the grinder without adding extra water.

Lungo is Italian, the corresponding English is "long", French is "cafe é allong é", Chinese means "long", refers to "use twice the normal amount of water, through the Espresso coffee machine, to make a coffee drink, a Lungo, to the effect that an" elongated Espresso "must be called by the Chinese name, it should probably be called espresso. Lungo is very popular in Italy. One serving is only about 60--85ml, and the double is 120 Murray-170ml. The decrease in the amount of water brings a more mellow taste than Americano. A regular Espresso coffee takes 30 seconds to extract, with a volume of 25 lungo 30 milliliters. If you extend the extraction time of Espresso to about one minute, the amount of liquid extracted from the coffee is about 50 murmurs 60 milliliters. This drink is called lungo.

Therefore, lungo is not what we often call Americano, nor is it easy to distinguish between Long Black,Americano and Long Black: the former is "Espresso + water", the latter is "water + Espresso", the order is different, while lungo, the extraction time is nearly twice as long as Espresso, and the volume of the extract is about double.

If the extraction time of Espresso is nearly halved, the resulting drink is called Ristreto, and if the extraction time of lungo is doubled, the volume of coffee liquid is nearly doubled, then this "longer" drink is called Caff è Crema, which is relatively rare. However, visit many domestic cafes, it is almost rare to provide Lungo and Ristreto coffee shop, probably the production also needs an independent bean grinder to increase a lot of complexity, we have to combine practice and relevant materials to make, we adjust the parameters, lengthen the extraction time found that the oil of Lungo is the most stable of the three, taste lighter than Espresso, but at the same time will be a little bitter. Compared with Americano, the taste is more mellow. (Lungo, Ristreto and Caff è Crema are all sketched in this article because of various parameters, without detailed explanation. If there are clear and detailed practices, you can send a message to the public platform of Coffee Aesthetics for discussion.)

The buttons of the Astria plus 4 you show that Espresso, Lungo, Ristreto and Caff è Crema have traces in the setting of the coffee machine.

Next, we will analyze the parameters of these kinds of coffee from a scientific point of view, combined with the data.

The equipment used in this test is Mahlkonig K30 bean grinder, Huijia KD310 coffee machine, Bodum Bistro American drip filter and COMPAK R8 bean grinder from left.

All the coffee beans used are coffee aesthetic sunburn Yega Xuefei SOE (available in micro-stores)

Two cups of coffee: Americano on the left, long black on the right and VST coffee concentration tester in the middle

20g coffee powder extract 60ml espresso and add water to 240ml or 300ml. The situation of oil is obvious, and the TDS value is always the same.

Parameter comparison: from the above parameters, it is not difficult to see that these practices probably follow the golden cup rule, the above we did not discuss beans, freshness, baking degree, bean quality and so on, can become the factors affecting the extraction. I hope you are interested to study on your own, and you are welcome to come to Viagra for discussion. WeChat account: gaowei893236
