Basic knowledge of Italian mocha brewing coffee

Mocha is a kind of distilled coffee. The coffee brewed from the mocha pot has a steady concentration and aroma. It is mainly suitable for Italian coffee. Popular in Europe, and Italian coffee machine belong to the use of high-pressure steam extraction coffee pot, but in price, size, more suitable for ordinary families to use. The water placed at the bottom is heated and driven by steam pressure so that the coffee is not extracted through the coffee powder in the filter. The body of the mocha pot has three layers, the water in the lower pot, coffee powder in the middle basket and the space in the upper pot is left for steam and coffee, of which the key parts are gaskets that do not let steam escape and pressure reducing plates that can be controlled. As for the filter cloth for filtering coffee residue, it must be purchased separately, cut the image as the size of the spout, and cover the coffee powder.

The design of mocha is more suitable for deep-roasted espresso, if you want to brew medium and light roasted coffee, you can also use it, but take out the coffee about 1 minute later. If you want to make the unique milk foam of espresso, you have to buy a stainless steel bubble pot and beat the whole milk into foam by hand, which is quite time-consuming. In contrast, even household espresso machines whose extraction pressure and temperature are not as stable as commercial models are easier to open a shop than mocha pots, while coffee machines priced below 10,000 yuan are mostly brewed under steam pressure.

(1) preparation utensils: mocha pot, filter paper or cloth, coffee powder, water, induction cooker or gas stove, alcohol lamp.

(2) suitable for coffee beans: deep-roasted coffee beans.

(3) Coffee powder dosage and grinding degree: 8 grams per cup of coffee powder (grinding degree: medium to fine).

(4) Water volume: 150ml. Step a) pour water into the kettle, about 150 milliliters per cup, and the height of the water should not exceed the outlet, so as to prevent steam from hurting people. B) put the coffee in the coffee box and beat the coffee powder flat. C) remove coffee powder around the coffee box and cover with filter cloth or filter paper. D) tighten the upper and lower pots and heat them at the heat source. E) when you hear the sound of cooing, turn off the heat source.

(5) preparation before brewing ○ in order to improve the extraction effect, the coffee powder put into the bucket should be pressed hard, and the steam in the upper half of the kettle should not be leaked, but should be well covered. ○ is used with the number of people. You must use a capacity appliance that is larger than the required quantity (in terms of the number of people). If the steam pressure is weak, the coffee drawn will be less delicious.

(6) the operation step ① injects the water into the lower pot, and the water height should not exceed the outlet hole, so as to avoid the hot steam ejecting from the bottom of the frame. ② puts the coffee powder into the coffee container and gently presses it with the bottom of the spoon (spoon) or the pressure plate to make the coffee surface smooth. Remove excess coffee powder from the edge of the coffee container. ③ wetted the prepared filter cloth and gently affixed it to the hole at the bottom of the coffee container. ④ places the coffee container on top of the lower pot and locks both. The ⑤ is heated on the fire source. ⑥ heating process will hear the sound of steam rising and water boiling, but open the lid to observe, when the steam no longer comes out, it means that the coffee is ready. ⑦ pours the brewed coffee into an espresso cup. The cooking secret of the mocha pot depends on the capacity of the ◎ kettle. If the water level is higher than the outlet hole, it should be flushed and boiled in stages to prevent the water from boiling. ◎ is suitable for granules that are only thicker than an espresso machine, so you can generally fill the container; if you like it thicker, press the plate gently until it is filled. The upper and lower pot of ◎ is locked and boiled on a gas stove or induction cooker. When the brewed coffee begins to rise, the stove should be turned down so that the coffee will not smell scorched. ◎ when the steam hole no longer gives off steam, it means that the cooking is complete; if it is used to boil light-roasted or medium-roasted single-item coffee beans, it can be delayed for about 1 minute. If ◎ is not too troublesome, you can buy a hand-made milk bubble pot and beat the whole milk into foam to make lattes or cappuccinos.
