Coffee as a drink, it can have an impact on different countries and societies in different ways, and carry different cultures, which is indeed the charm of coffee.

However, no matter how splendid the coffee culture is, if we put aside the coffee itself, all cultures will be out of the question. From the extraction and roasting of coffee beans to the extraction and finished products of coffee machines, the steps of coffee production have rarely changed, but the coffee finished products obtained by different coffee varieties and different production methods have different enjoyment and taste in the process, which is even more interesting than coffee culture.

But what exactly are we drinking coffee? Before you answer the question of "metaphysics", you may need to know a few basic terms to measure the flavor of coffee:

Aroma: the aroma of coffee actually includes the dry aroma of coffee beans and the aroma emitted after coffee conditioning is finished.

Bitterness: in general, the deeper the roasting degree of coffee beans, the more bitter.

Acidity: in fact, the "acid" in coffee is an important part of the flavor of the whole cup of coffee. Unlike the "acid" of lemon, the sour taste of coffee is relatively fresh and refreshing. Some people use the difference of "pure water and bubble water to stimulate taste buds" to compare the acidity of coffee.

Mellow: also known as "taste", can be understood as the intensity of the drink sensed by the tongue. Here we can compare the taste difference between pure water and cream. Pure water has the lowest mellowness and dense cream has the highest mellowness.

Aftertaste: like red wine, the residual taste of coffee in the throat and mouth can measure the quality of coffee raw beans to a certain extent; some coffee aftertaste is long and clear, some coffee aftertaste is short and vague, the quality of coffee raw beans of the former will be higher than the latter.

Flavor: the flavor of coffee is the result of aroma, bitterness, acidity and mellowness, which refers to the overall impression of a type of coffee.

In fact, the quality of a cup of coffee is affected by every process of planting, picking, roasting, grinding, and extraction of raw beans, while the cup of coffee we drink can be said to be the "lifetime" process of each bean in the cup.

In fact, different varieties of coffee beans have different flavors, and there are no absolutely good coffee beans, only coffee that suits your own taste. If you want to find out the "good coffee" that suits you, you might as well taste different coffee beans, which will help you find your favorite coffee.

Nowadays, there are more than 100 different varieties of finished coffee in the world. After picking and processing the raw beans, the finished coffee beans still need to go through an interesting step-baking, which allows different varieties of coffee to release their own unique aroma.

In the process of baking, the water of raw coffee beans will slowly evaporate, the color will deepen and the volume will expand, the aroma of coffee beans will gradually precipitate with oil, and the original chlorogenic acid content will gradually decrease with the baking process, releasing better fruit acid.

On the other hand, the roasting time of raw coffee beans is different, and the appearance and taste of the formed coffee beans will be different. Usually, the degree of coffee roasting is divided into eight grades, of which "very shallow roasting" has the lowest roasting degree, "heavy roasting" has the highest roasting degree, and their flavors are different:

Very shallow baking: the smell of coffee is insufficient, the taste of vanilla is strong, and it is rare on the market.

Light roasting: high acidity, slightly fragrant, suitable for brewing American coffee

Moderate roasting: to some extent retain the original flavor of coffee beans, slightly higher acidity, with a bitter taste, suitable for brewing American coffee or mixed coffee

Concentration baking: the acidity and bitterness are balanced, the aroma is heavier, and the taste is rich.

Urban roasting: the most popular baking degree, with acidity lower than "concentration roasting", often used to make French coffee.

Deep roasting: bitter taste, low acidity, full aroma, long aftertaste, often used to make black coffee or iced coffee

French baking: bitter taste, light sour taste, with burnt smoke, chocolate aroma, strong taste, most suitable for making Viennese coffee

Heavy roasting: bitter, basically sour, strong and complex taste, with a strong scorched taste, suitable for making espresso.

Combining the performance of the above eight baking degrees and different styles, it can be summarized as follows: the longer the coffee beans are roasted, the lower the caffeine content and the less sour taste.

After learning about coffee tasting skills and the effect of bean roasting on coffee taste, you may be eager to make your own cup of coffee. But before you start making coffee, there is another question-should you choose coffee powder or beans when making your own coffee?

Before you answer this question, you need to know that the coffee powder purchased on the market is actually obtained by grinding coffee beans. If you directly use coffee powder to make coffee, you can eliminate the step of grinding coffee beans yourself.

However, it is important to know that the aroma of coffee mainly comes from the oils precipitated during the roasting of coffee beans, which are stored in the tiny holes inside the beans; if the ground coffee is not brewed in time, the oil containing coffee flavor can easily volatilize in the air. In addition, the area of ground coffee in contact with the air will increase, and it will be more vulnerable to damp deterioration, directly affecting the original taste of the coffee.

In addition, some manufacturers in the production of coffee powder, may be mixed with other varieties of coffee, in order to make higher profits, it is difficult to ensure the unity of coffee varieties in a bag of coffee powder.

Obviously, if you want to enjoy the fun of making your own coffee while enjoying pure strong coffee, buying coffee beans directly will be a better choice than coffee powder. However, generally speaking, coffee beans baked within two or three days are "fresh", and it takes two days of "exhaust" after baking to get the best coffee flavor. In addition, in order to maintain the best flavor of coffee, you should not buy too many coffee beans at home, and the coffee beans should not be kept for more than two weeks after opening the bag.

If you find it too troublesome to make your own coffee and want to enjoy pure and full-bodied coffee at home for the first time, it's a good idea to buy a fully automatic coffee maker for your home.

Take the Siemens fully automatic coffee machine TI301809CN as an example, the design of the piano paint shell at home can add some depth and elegance; on weekdays, you only need to pre-put the required coffee beans in the coffee bean bin on the top of the coffee machine, fill the water tank with a certain amount of pure water, turn on the machine when needed, touch the desired coffee varieties, and wait 20 to 30 seconds for a cup of strong coffee to be delivered to the cup. Soon, the fully automatic coffee machine completes the complicated grinding, extraction and other actions for you, coupled with the pressure of the coffee machine 15bar, the obtained Espresso espresso is more rich in oil and retains the original quality and flavor of good coffee beans.

The ceramic grinding tablets used in the interior not only ensure the durability, but also are not easy to generate heat, which ensures the original taste of coffee before extraction, while the water tank with a capacity of 1.4L is full at one time, which can meet the production of multiple cups of coffee.

In fact, not everyone can accept the taste of pure coffee such as Espresso, and many people prefer fancy coffee drinks such as Cappuccino, Latte, Macchiato and so on.

Espresso, coffee é Cr è me and other pure coffee can be easily obtained on Siemens TI301809CN, and even fancy coffee such as Cappuccino with distinct taste and Latte Macchiato with soft taste can be easily made with one click.

Just pour the right amount of milk into the cup, insert the milk foam device of the coffee machine into the coffee cup, touch the Cappuccino button or Latte Macchiato button on the coffee machine, and automatically complete the steps of milking, extraction, mixing coffee and so on; the finished Cappuccino and Latte Macchiato milk bubbles taste dense. The adjustable coffee concentration and the amount of coffee cup can basically meet the needs of different people for different tastes and portions.

The built-in "instant temperature control system" can not only heat up quickly, but also keep the extraction temperature of ground coffee beans at the best 90 ℃ ~ 95 ℃, so as to ensure the pure taste of Espresso espresso.

This kind of family professional entry-level automatic coffee machine, while liberating your hands, its strict production process ensures the stability of the coffee product. the finished coffee can be comparable to the professional coffee shop, and you only need to wait for a short time in front of the coffee machine.

For the home coffee machine, simple daily cleaning is also very necessary. In addition to automatic calcium removal procedures and cleaning procedures, TI301809CN will automatically clean the internal pipes before and after turning off the phone in daily use to ensure the cleanliness of each cup of coffee. The design of the front door greatly facilitates daily cleaning and maintenance, and the internal detachable extraction unit only needs to be washed under the faucet after disassembly.

If good coffee beans are the beginning of a good cup of coffee, then the process of coffee extraction and brewing is the propellant to enjoy coffee, and tasting coffee products is the positive of all this.

From the planting, picking and baking of coffee beans to grinding and extraction, the ultimate intention of each link is to pave the way for the perfect positive film of "tasting coffee products". Only by paying attention to each link will the final product be presented in the best condition. The variety, picking method and baking depth of coffee beans directly affect the quality of coffee beans; only good grinding and extraction equipment and methods can release the quality of coffee beans to the coffee cup to the maximum extent.
