Basic knowledge of Coffee who changes Coffee from solid to liquid

Once had the honor to be invited to a coffee player's shop, it is a very feel at home shop, the sofa is very comfortable, the light is very soft, but what moves me most is coffee. Watching the host demonstrate a handful of raw beans, after baking, grinding, cooking, and finally into the cup, indulge in the coffee phenomenon-the process from solid to liquid, and the formation of this phenomenon, or the achievement of this art, it should be coffee equipment.

Roasting tool-- make coffee beans jump happily

More and more coffee players are fond of roasting their own coffee beans, because usually after the coffee beans are roasted, they can only keep their freshness for 1 to 7 days, and then they will begin to stale, leaving only bitterness and no mellow taste. Therefore, self-baking can ensure the freshness of coffee beans. They describe this feeling as frying a plate of fresh vegetables or steaming a fresh fish, which tastes better than the dishes at a banquet and can add a lot of interest.

The traditional roaster is drum-type, which has the characteristics of stewing, which will make the coffee beans more mature and full-bodied. The household drum roaster can bake half a pound of coffee beans at a time, and the baking time (including cooling and producing beans) takes about 210.25 minutes. If you want to roast deeply, you only need to increase the time. When in use, just put in the raw beans, set the baking degree, press the start button, from baking to cooling, the roaster can do it automatically, and all you have to do is slowly enjoy the coffee beans jumping up and down happily in the roaster.

Grinding tool-- make coffee beans powder in detail

In order to blend with the water, coffee made the greatest sacrifice-to pieces. Before brewing coffee, the beans must be ground into fine grains to increase the contact area between water and coffee in order to extract the delicacy.

In fact, the bean grinder is more important than the coffee machine, and players suggest choosing a "sawtooth grinder" because it can grind a uniform coffee powder quickly and steadily.

The operation method of the sawtooth bean grinder is very simple, generally speaking, it will have two setting functions, one is to set the grinding degree, the other is to set the grinding time. The degree of grinding is mostly expressed in Arabic numerals, and the smaller the number is, the finer the grinding is.

On the top of the bean grinder is a funnel shaped box containing unground beans, and below is a drawer to hold the ground coffee powder.

When you choose to buy a bean grinder, you should pay attention to its power, usually between 70 watts and 150 watts, the higher the better, the higher the power, the faster the grinding speed, and the shorter time the coffee powder stays in the sawtooth, so it can grind the coffee powder at low temperature.

Brewing tools-blend coffee powder with water

To brew a good cup of coffee, you need not only fresh coffee powder and slightly harder water, but also a set of easy-to-use brewing tools. There are three main types of coffee machines in common use.

Drip filter: wet the coffee powder with water and let the coffee liquid flow through the filter cloth or filter paper and flow into the container at the speed of natural fall. Basically, this method does not soak the coffee powder, just let the hot water pass slowly through the coffee powder.

Both the drip cup and the electric coffee maker fall into this category and are the simplest brewing tools that can make clean and brightly colored coffee.

Bubble type: put the coffee powder into the pot, soak it in hot water for several minutes, and then filter out the coffee grounds by a filter cloth or screen to form a cup of coffee liquid.

Siphon pots, drip pots, Belgian coffee pots and Vietnamese coffee pots are all follicular brewing tools, and they all have a soaking process to form a more complex taste.

High-pressure type: use pressurized hot water to penetrate the compacted coffee powder to produce a thick cup of coffee in this form of tools such as a mocha pot and an espresso machine.
