What beans are used in American coffee machines in convenience stores? coffee beans suitable for American coffee are recommended

Nowadays, the atmosphere of drinking coffee in China is becoming more and more hot, not only are the streets full of coffee shops, but even daily convenience stores are beginning to offer freshly ground coffee, and you can get a cup of drip-filter American coffee at the press of a button. So is this American coffee the same as the American coffee we drink in the coffee shop?

American coffee machine is extracted under atmospheric pressure.

There are many utensils for making coffee, including French filter pots, mocha pots, hand filter cups, and all kinds of coffee machines. Among them, the mechanical coffee machine is mainly divided into drip filter coffee machine and Italian coffee machine.

The structure of the American drip filter coffee machine is relatively simple, so the price is more affordable and the function is relatively simple. The trickling filter is usually divided into two layers, the upper layer is a funnel-shaped container with a filter paper or metal filter, and the lower layer is a glass or ceramic coffee pot. The American drip filter also allows hot water to flow through the coffee powder into the lower coffee pot to extract the coffee, but compared to the Italian coffee we drink in the coffee shop, the hot water is extracted at atmospheric pressure. In addition to cooking coffee, you can also make tea.

Because the principle of the American drip filter coffee machine is to pour water on the coffee powder, and then flow to the next pot, without receiving the effect of external force, so the taste of coffee is relatively light. Of course, it can not be used as the base of milk coffee, so it can only be made black coffee. If our request is not high, just want to have a cup of coffee, Qianjie thinks that the American drip coffee machine is also a very good choice.

Italian coffee machine is pressurized extraction.

Espresso was invented in the early 19th century. In order to extract a cup of strong coffee in a short time, Italians thought of using steam pressure to pass high-temperature and high-pressure water through coffee pressed powder to speed up the original trickling extraction rate. With continuous improvement and update, our common semi-automatic / full-automatic espresso machine has been derived.

Italian coffee machine usually has a boiler, the hot water will be pressurized, through the coffee powder trough, extract coffee, so it is also called pump coffee machine. The coffee brewed by this kind of high-pressure hot water is relatively thick and has emulsified oil, which is called espresso Espresso. The American coffee we drink is based on it, so baristas need to adjust a standard espresso to ensure stable production in the store.

Espresso symbolizes coffee with a complex and condensed flavor, and no other brewing method can show such mellow thickness and texture. If you want to get a good cup of espresso, excellent extraction is essential. There is a balance between aromatic compounds and taste compounds in the cup. Qianjie said so much, I believe you all know that the Italian coffee machine is much more complicated than the American drip filter coffee machine!

What is American coffee?

American coffee is a kind of black coffee, which is composed of espresso and water without other ingredients. During World War II, coffee was so popular in the US military that Americans drank the bitterness of unaccustomed espresso and diluted it with water to reach their acceptable concentration. Later, in cafes opened in the United States, the Italians also "do as the Romans do" to launch "coffee with water" based on Italian concentration, and this coffee has been very popular ever since.

There is no fixed proportion of American coffee, each store will have its own production standards, the aim is to present the flavor and taste of the coffee. According to the proportion of Qianjie tried and prepared many times, 40g coffee liquid was poured into 240g 88 ℃ hot water, and the hot American coffee was made. If ice American coffee is produced, the hot water will be replaced with 120 grams of ice and 120 grams of normal water, which tastes best before the ice melts. Ice American coffee in front street shows strong whisky aroma, sweet and sour berries, refreshing and greasy, so it is especially popular in hot Guangzhou stores, while hot American coffee highlights the mellowness of roasted nuts and chocolate, the sweet and sour fermentation of tropical fruits, and the aftertaste of vanilla.

It is suitable to recommend American coffee beans.

When buying coffee beans in Qianjie, Qianjie will ask which way to extract. If it is an American drip filter coffee machine under atmospheric pressure, Qianjie thinks that all the coffee beans on the bean rack for hand flushing are suitable, just choose your favorite flavor type.

If it's a pressurized espresso machine, it's different. Due to the fine grinding, high water temperature and high pressure extraction of espresso, espresso converges a variety of flavors, and various flavor compounds hit our tongues exponentially. Therefore, if we use lightly roasted single coffee beans for extraction, the taste may be too strong to mask the aroma of the coffee. Therefore, Qianjie suggests blending coffee beans, using the way of learning from each other to ensure that each coffee bean can show a balanced and stable aroma and taste.

Qianjie recommends the self-baked "sunflower warm sun mixed coffee beans" in Qianjie, which is made of Ethiopian sun red cherry coffee beans (30%) and Honduran sherry barrel coffee beans (70%). The entrance of Italian espresso is very rich dark chocolate flavor, with a strong aroma of caramel, the aroma after swallowing is memorable. Both American coffee diluted with water and latte with milk are rich in aroma and taste. In order for everyone to drink the full aroma of coffee and enjoy the most complete taste stage, Qianjie only delivers freshly roasted coffee beans within 5 days.
