Coffee can also be DIY, do you want to try it?

Like the diversification of Chinese tea, coffee liquid has its own classification. Gourmet coffee includes Blue Mountain Coffee and Mocha Coffee, one can be king and the other can be called queen. Blue Mountain Coffee, which gets its name from its origin, is produced in the Blue Mountains region of Jamaica. It produces very little and is very expensive. It is certain that the Blue Mountain Coffee in general cafes is made by imitating the flavor of Blue Mountain Coffee. Mocha coffee is produced in Ethiopia, with small and fragrant beans, strong sour and mellow taste, moderate sweetness and unique flavor. In addition, Colombian coffee and Santos coffee are mostly produced in South America. Indonesian civet coffee, commonly known as Kopi Luwak, is also a relatively precious one. But overall, there are two main types of coffee trees in the world, Arabica and Robbata, which account for 90% of the world's production. Among them, Robusta kind of flavor is poor, sour, rigid, but the yield is higher, because most of the instant coffee is mainly to extract caffeine, so it will use the cheaper one.

Mocha, latte, cappuccino and macchiato concentrate are all fancy coffee, that is, espresso is made with different amounts of milk, cream, chocolate syrup or whipped cream, and their tastes and practices are also very different, so coffee D IY is also possible. But before DIY, we should buy coffee beans. The prerequisite for buying coffee is fresh, and old coffee is easy to lose its flavor. At the same time, you can not choose damp coffee, you can grab one or two in the mouth to chew, if it is relatively crisp, there is no moisture, lips and teeth fragrance of coffee must be the top grade. In addition, squeeze it with your hand, if the particles are full, the quality will be better.

It should also be noted that the freshly fried coffee beans are not suitable for drinking immediately, but should be kept for a week or so. Individuals should choose coffee beans of similar quality, size and color when buying coffee beans, otherwise it is easy to buy some inferior products with mixed advantages and disadvantages. But for comprehensive beans, different size and color is a normal phenomenon. In short, when choosing and buying coffee, you should pay attention to its freshness, aroma and whether it is stale or not. if you drink it personally, you should not buy too much, and you can drink it in half a month.

After we have selected, let's prepare the DIY equipment. For DIY tasteful coffee at home, you need a coffee grinder and a set of brewing equipment. If you want DIY according to its characteristics, you need to make fancy coffee cups, chocolate syrup and other containers. Generally speaking, it is better to choose manual grinder, and the price is between one hundred and several hundred yuan. We can choose siphon or drip pot, but if we use siphon coffee maker, we need to heat it with alcohol. For convenience, we can choose a dripping coffee pot, which is relatively simple, just put coffee beans or coffee powder into the pot and add the right amount of water, commonly known as "American coffee pot". There is also an Italian coffee machine that allows steam to quickly extract coffee through coffee powder through high pressure and high temperature. the best temperature for brewing coffee is 90 ℃-98 ℃. The Italian coffee machine is well controlled and is suitable for flower extraction, but without the fun of siphon coffee. Of course, it is also possible to DIY in the roasting stage before grinding coffee, as long as there is a roaster, but the method of operation is somewhat difficult.

However, in the DIY process, we should pay attention to: when grinding beans, the size of the powder depends on the way it is cooked. Generally speaking, the shorter the cooking time, the finer the powder will be ground, and vice versa. The ideal time to grind coffee is before it is boiled. Because ground coffee is easy to oxidize and lose its flavor, especially without proper storage, coffee powder is also easy to change flavor, so it is naturally impossible to brew mellow coffee. In terms of actual cooking, the E spresso machine takes a very short time to make coffee, so the coffee powder is ground the finest, and the coffee powder is as fine as flour; it takes about 1 to 3 minutes for siphon steaming coffee, and the coffee powder is ground in medium thickness; while the American coffee maker and hand-brewed filter generally have a fineness of sugar. If combined with a siphon coffee pot, you need to start grinding after the water in the coffee pot bubbles, and master the scale and weight. If you don't want to go to so much trouble, you can use an Italian mocha pot.
