Basic knowledge of Coffee how do we process coffee?

Coffee processing generally requires coffee grinders, coffee cookers, coffee ovens, timers, coffee spoons, sealed coffee cans, cream guns, coffee cups, milk cups and sugar cans, stainless steel buckets and other utensils.

Coffee grinder, electric bean grinder, suitable for grinding a large number of beans, and can be adjusted at will, fast and convenient, suitable for business use; propeller electric bean grinder. Small amount of grinding beans, and can not grind beans continuously for a long time, the price is cheap, suitable for the bar is not busy and family use; hand grinding machine, simple shape, steel, wood, etc., suitable for decoration, family play, but grinding beans is very slow, so it is not suitable for business use.

Coffee steamer, siphon pot (SIPHON, plug wind), transparent glass pot, easy to prepare and easy to learn, pure breed and coffee with a small number of cups are suitable for this way. The cooking time is only 50 to 60 seconds; the Italian espresso pot / (ESSPESSO) / mocha pot, made of steel or aluminum, is heated directly, the cooking principle is similar to the siphon pot, but the flavor is stronger. Either for business or for home use; drip type coffee brewing equipment, simple filter bag type (method is more difficult to master, and taste lighter), electric coffee machine, performance and price difference, respectively suitable for family or business fast food; cappuccino machine. Add steam vents to the espresso machine to make rich foam and cover a cup of espresso.

Coffee stove, alcohol stove, usually with siphon pot for sale, but the firepower is small, it is not easy to adjust firepower, so it is not the best choice for business use. Steel gas stove, safe and convenient, adjustable firepower, gas supplement is also very convenient, suitable for family use, the cost is slightly higher; electronic gas stove, professional coffee stove, can be directly connected to liquefied gas cylinders, low cost, adjustable firepower, easy to use, according to the need to choose a furnace with one core, a furnace with two cores and other professional stoves, very suitable for business use. Timer, choose stopwatch or hourglass, etc., the cooking time has a great impact on the taste of coffee. Coffee spoon. It is usually sold with a siphon pot, about 10 grams per spoon. Sealed coffee cans. First of all, cut off the air, play the role of moistureproof and fresh-keeping; secondly, because coffee is very sensitive to smell, do not grasp or use a coffee spoon with a peculiar smell.

Coffee cups, cups and spoons are a set. It is usually necessary to prepare four kinds of coffee cups: first, ordinary coffee cups; second, espresso cups, often straight round, each cup is about 90 milliliters, filled with about 70 milliliters; third, single coffee and cappuccino cups, full cup 200ml, eighth full about 150 milliliters; fourth, iced coffee cups and other fancy coffee cups. Milk cups and sugar jars can also be used in small packages of cream balls and sugar packets. Cream gun, commonly used in making fancy coffee. We also need stainless steel buckets and egg beaters.

Once the coffee beans are processed, the effective time to keep the flavor is shortened. The new coffee beans we mentioned can be preserved for several years, but after roasting, the whole flavor can only be preserved for a week. After two weeks, the flavor is only half at most, and after being ground, the flavor can only be preserved for a few days at most.

In any good coffee shop, when you buy pure beans or mixed coffee beans, the owner may ask you if you need to grind. If you want to grind, you should tell him the adjustment method you use, because it will affect the degree of grinding. Of course, to extract the best flavor from coffee beans also depends on the degree to which the ground coffee powder is soaked in hot water.

Generally speaking, the shorter the soaking time, the finer the grinding. The most basic grinding methods of coffee beans are: "Coarsegrind", "Mediumgrind" and "finegrind". The soaking time of finely ground coffee is shorter than that of coarse grinding, so it is suitable for distillation, which takes the least time, so coffee powder finer than sand is needed. While rough coffee is more suitable for traditional pot flushing methods, such as piston method, coffee pot method, drip method, filter method and so on. It can be seen that grinding an ideal can of coffee is as difficult as walking barefoot.

But don't be too dogmatic. If you try to filter coffee fines ground by fine distillation in a filter, you will find that it takes longer to filter the water without improving the flavor. If you make strong or light coffee, the best and easiest thing to do is to increase or decrease the ratio of coffee powder to water without changing the way you grind it.

The hardest part of coffee-related activities is baking coffee beans at home.

When making high-quality coffee, whether the beans are fresh or not is very important. We all have the experience of buying stale coffee beans from roasters, even once. This is not comparable to making coffee with self-roasted coffee beans. Then grind and make coffee in your own kitchen. It's worth a try.

The easiest way is to bake coffee beans in the oven. The biggest advantage of this is that it adjusts the temperature so that the smell of roasted coffee does not pervade your home. Heat the oven to 230 degrees in advance. Remember to keep the coffee beans well ventilated and don't spread the beans too thick. After baking for about 10 minutes, observe the change of color. Pay attention to the crackling sound of coffee beans and check the color all the time. When the coffee beans are only a little lighter than you want, remove them from the oven to cool. The residual heat will cause the coffee beans to continue to be heated for 2 Mel for 4 minutes.

You can also buy a home baking stove for use on the stove. But the best is the traditional flat pan or popcorn (popcorn) model. Use a handle to manipulate two vertical pieces of metal inside the machine, which can rotate the coffee beans during baking. You can buy it in a second-hand store or a good kitchen utensils store. You can also buy an inexpensive oven thermometer there. After the coffee is roasted, take them out of the grill, put them in a heat-resistant bowl, and put the bowl by the window or outdoors.
