If the coffee bean has lost its fragrance or smells stale, it means that the coffee bean is no longer fresh and is not suitable for purchase. Freshly fried coffee beans are not suitable for immediate drinking, so they should be stored for a week to allow the gas in the beans to be completely released. Generally speaking, the best drinking period of coffee is one week after frying, when the coffee is freshest and has the best aroma and taste.
In addition, the purity of coffee beans is another consideration. Professionals choose coffee not necessarily by the size of the particles, but by grabbing a handful of regional coffee, about dozens of pieces, to see whether the color of each single bean is consistent and whether the particle size and shape are similar, so as to avoid buying inferior products disguised as mixed beans. But if it's blended coffee, it's normal to have different sizes and colors. Moreover, deep roasting on fire will make coffee beans yield oil, but light roasted coffee beans yield oil, which not only reduces the mellow degree, but also leads to astringency and sour taste. In a word, when buying coffee, we should pay attention to its freshness, aroma and off-flavor. The ideal purchase amount is to finish it in half a month.
Freshness is the most important factor in buying coffee beans. There are several steps to judge whether the bought beans are fresh:
1. Look: Grab a handful of coffee beans and feel whether they are solid beans with your palm.
2. Smell: Is it enough to smell the aroma close to your nose?
3, pressure: fresh coffee beans are pressed fresh and crisp, and when they crack, there is a fragrance floating out. You can take a bean and bite it twice in your mouth. The crisp sound means that the beans are well preserved and not wet.
4, color: dark coffee beans with black, boiled coffee has a bitter taste; Yellow coffee beans, the brewed coffee is sour.
? Good coffee beans: neat shape, bright color, single frying and baking, mellow after brewing, full of stamina.
? Bad coffee beans: different shapes, incomplete individuals, faint fragrance after brewing, not sweet enough.
Question 2: How to buy Starbucks coffee beans? 1. Preference for rich flavors.
If you have a strong preference to go to Starbucks to buy beans, it is recommended that the baking level be BLOD or X-BLOD. This can be used as ESP.
But if it is medium, choose House Blend, which is our first choice.
The goods he has there can only be said to be average.
2. Not too sour, not too astringent and smooth in taste. What beans are good? Briefly describe the background of beans. The price is not too expensive.
Not too sour, too astringent and too slippery. At the same time, if you want to do ESP or Mocha, I would recommend Verona, Pike, and others.
If you make your own siphon or pressure cooker, buy a House Blend or Kenya. The phoenix dance is auspicious and sour.
The above two beans are both 250g, both within 100. I forgot 85 or 95. . . It's up to you, Gui You. .
What is the background of this bean? Starbucks beans have no background. It's all beans. But that doesn't mean it's not good to spell beans. There should be good and bad spellings. Please rest assured at Starbucks.
In fact, if you don't choose Starbucks, you can buy illy beans, which is an Italian national treasure. There are shops in Shanghai, but not elsewhere. If you go through the formal channels, the price is about 85 ~ 100, which is also 250g, and you can get it around Taobao 65.
ILLY's words recommend red cover or green cover, the red cover is comprehensive, the black cover is deep baked, and the green cover is low.
Regarding whether the beans are fresh, you must pay attention to the production date when buying them. If you have got beans for more than a year, it is not recommended to buy them, especially those with poor sealing. Coffee powder is preferably freshly ground. Once the can or bag is opened, please eat it as soon as possible. If one person drinks a bag, it will take as long as a week or a month. The quality of unopened beans will be greatly affected if they are kept for a long time or placed in a humid place. You can send me a message specifically.
3. The brewed coffee had better have refreshing effect, and it won't be bad for your health if you drink it for a long time.
As long as good beans has a refreshing effect, whether it's Starbucks or COSTA, of course Maxwell and Nestle can't count. .
Drinking for a long time will not be bad for your health. Depends on what you say. One cup of coffee a day, for both men and women, is only recommended, with a maximum of two cups. After all, it contains caffeine, which is refreshing, but it is especially bad for men, and once coffee is always drunk 3 or 4 cups a day, both men and women will have freckles, which is difficult to treat.
Therefore, drinking a cup every day is the best choice. Not only refreshing, but also beneficial to the stomach.
Drink decaffeinated coffee for heart disease and hypertension, because people who are sensitive to caffeine will have palpitations because of drinking coffee. Please drink decaffeinated coffee or drink less in this case.
To emphasize, don't smoke while drinking coffee or after. Smoking while drinking coffee will affect your taste buds and mask the rich aroma of a good cup of coffee. It has a great influence on tasting a cup of coffee. People will feel relatively uncomfortable whether they smoke while drinking coffee or after drinking coffee.
4. What machine is it made of?
If you are a coffee lover, I might give you a list. For more details, please send a message directly to Baidu and ask me.
(1) Both automatic coffee machines and semi-automatic coffee machines are imported with good quality. If the price is expensive, they will rise to the w rule 10, and there is no guarantee after the sale. Besides, you have to buy it abroad. Not recommended.
(2) Doufang is a must. The bean mill is electric and hand-operated, which is cheap, but we should pay attention to the quality. If it is electric, it will be very good for beginners in Taiwan Province Province.
(3) thermometer: must buy. Suggest TIAMO in Japan
(4) kitchen scale: must buy. Beginners must have a small electronic scale.
(5) Kitchen timer: you can buy it or not, and you can use a watch instead. Of course, you are just a player, so you should be your professional kitchen timer.
(6) Flower Cup: Must buy. Learn the basic flower pulling tools, because if you want to learn how to make your own fancy coffee such as latte, cappuccino and mocha, someone knows.
(7) Milk foam machine: it is recommended to buy. Because if you decide to buy a semi-automatic one, it has a high-pressure nozzle, so you can directly use it to make milk bubbles. Don't buy a semi-automatic one, you must buy a milk foaming machine. There are two types of milk foam machines: manual and electric, and manual is cheaper. Electric ones are recommended to be cheap and practical in Japan, and Taobao sells them.
(8) Coffee utensils: This is troublesome, including mocha pot, siphon pot, pressure pot, pointed mouth pot, Evelyn, Lin Chong, ... >>
Question 3: How to choose coffee beans imported from Blue Mountain, Mocha, Italy and Mantening is better, mainly depending on the fullness and baking quality of coffee beans. The beans baked in many small domestic workshops are not uniform enough, and the quality of each batch is slightly different, which is not as constant as the taste of imported beans. There are also many carcinogens in baking by yourself, which will cause problems if you drink it, and you can drink it often.
Question 4: How to choose green coffee beans? What kind of raw beans are good quality raw beans? Look at the surface of the beans first. Fresh and high-quality raw beans with shiny surface. In addition, the processed edamame, with uniform color and uneven surface color, can't be called good beans. When shopping, be sure to choose a uniform color. Secondly, the particle size is consistent, which is also evidence of good quality management. Ensure that the particle size is consistent when purchasing. Uniform and tidy coffee beans can achieve consistent baking effect; Otherwise, some are too deep and bitter, and some are too shallow and sour, which will affect the overall taste of roasted coffee beans. Raw beans are divided into several grades according to the quality standard, which varies from place to place, basically according to the size and shape. The higher the grade, the better the quality. At present, because the domestic raw coffee bean market has just started, the raw coffee beans sold are mainly low-grade futures beans. The raw beans you get usually have many defects. Flawed coffee beans are very harmful, including mutant beans that are not lentils or round beans. Because of abnormal development, raw beans break at the center when they are shelled. This kind of bean is prone to uneven phenomenon during baking. During the processing or cleaning of fermented beans/black beans, the beans are fermented internally. It has a fermented sour taste. Immature coffee beans/white dead beans are harvested when the coffee fruit is not fully ripe. This kind of bean is ivory after baking and tastes green. Moldy beans are affected by moisture and rain during processing and transportation, and mold breeds. As long as one bean is moldy, it will soon spread to others, so be sure to pay attention. Worm-eaten coffee beans are eaten by a pest called coffee borer. Coffee beans have insect eyes, which makes coffee taste. Dried fruit enters the drying process with skin. In the process of non-washing processing, raw beans can be taken out of the shell, but in the process of washing processing, this state becomes defective beans. Heterogeneous beans, such as Robusta beans mixed with Arabica and lentils mixed with round beans. Small gravel can easily damage the bean mill and can be found in a wide range of sunlight. When picking, we spread the beans in a well-lit place, and it is more efficient to pick them with both hands. Basically, coffee beans that look uncomfortable can be picked out. Only by selecting neat beans can they be roasted more neatly and taste more pure. If there are too many unexpected factors, it is impossible to judge the true taste of coffee beans themselves. Ordinary commercial coffee beans can also reach a very high and expensive grade, even the level of refined coffee, through their own selection. In terms of coffee varieties, not all Arabica beans are selected coffee, only a few high-grade coffee beans come from mountainous areas or are considered as selected coffee after strict selection and classification, accounting for only 10% of the global coffee production. As for Robusta beans, they have all entered the commercial coffee market, and only a few excellent beans can be regarded as selected coffee. Looking at coffee from the way of treatment: Because the ripening time of coffee cherries is different, good coffee must be picked by hand for 3~6 times, and care must be taken during the treatment, whether it is sun exposure or water washing. Raw coffee beans must be strictly selected and graded to ensure the stability of their quality. Although some areas have good local conditions and can produce excellent coffee, they can't be classified as selected coffee if they are not handled properly or are only secondary products left over. The American Coffee Selection Association has printed a green coffee classification table, which clearly and completely defines flawless raw beans and coffee with special flavor as selected products. The choice of coffee is absolutely special, far beyond the level of good drinking. Looking at coffee from the way of roasting: the year, type, room temperature and water content of raw beans are closely related to roasting temperature. Generally speaking, the selected coffee is generally roasted in small batches, which requires strict testing and analysis in advance, and then the roaster will always take care of it until it is roasted to the best state. Only by ensuring the uniform cooking of coffee beans inside and outside can the quality be guaranteed to be perfect. From the perspective of freshness, selected coffee: fresh coffee is considered as selected coffee. Freshness here refers to the freshness after baking, not the freshness after harvesting raw beans. After roasted coffee beans, the flavor reaches its peak in about 1~7 days, which is the best drinking time; Once stored for too long, coffee will naturally decline and suffer from oxidation, and its flavor will naturally be worse than before. From the way of selling coffee, it is very important to keep coffee beans fresh, and the baking date should be kept within 7 days, so as to make good coffee. On the contrary, commercial coffee is packaged with inferior coffee beans, coffee powder or instant coffee in tin cans, glass cans or plastic bags. Look at coffee from the product name: good coffee has its own characteristics, and it doesn't want to be anonymous, just called coffee.
Question 5: Choose coffee beans and make your own coffee to buy coffee beans. Pay attention to choose products with QS certification. Now the country has included coffee beans in the scope of enforcement. If there is no QS, it means that this product does not meet the food safety regulations.
About coffee grease: when coffee gets wet, Italian coffee beans should have grease. The law of grease is as follows: fresh medium and deep roasted coffee beans will have grease on their surfaces, such as Italian, charcoal roasted coffee beans and mandolin. And lightly roasted coffee beans have no grease on their surfaces, such as Blue Mountain, Mocha and Colombia. If there is no grease on the surface of coffee beans with medium depth, it means that this package of coffee beans is not fresh. Similarly, lightly roasted coffee beans are not fresh if they have grease on their surfaces.
Brazil: The most important coffee producing area in the world, with the total output accounting for 1/3 of the world. There are about 65,438+00 states in the vast territory that produce coffee beans in large quantities. Brazilian coffee tastes mellow, slightly sour and sweet. It is famous for its smooth taste and is considered as an indispensable raw material for making mixed coffee.
Colombia: The world's second largest coffee producer, accounting for 12% of the world's total output, second only to Brazil. Colombian coffee beans are pure in quality and can be called standard beans in coffee beans. Colombian coffee beans are big, light green and particularly heavy in taste, and are widely favored because of their rich and unique aroma. The taste is sweet, sour and bitter, and it can produce multi-level flavors with different baking degrees.
Mocha: high-quality * * * flavor, dry and slightly sour, moderate alcohol content, pure beauty and strong texture, and wonderful aftertaste of dark chocolate. Ethiopia, produced in Africa, has a unique aroma, excellent acidity, sweet taste and very original flavor. Mocha coffee is also loved by many people. Because of its rich flavor and unique aroma, many bar chefs like to use it to prepare iced coffee. After adding sugar and creamer, its aroma concentration is excellent.
Mantening: Coffee with the best combination of aroma and concentration, with large particles and hard beans, was once considered as the best coffee before the appearance of Blue Mountain, because it is rich and mellow in taste, not astringent and sour, with high alcohol content, bitter and fragrant, and quite individual. After careful tasting, there is still a hint of chocolate and nuts between the lips and teeth.
There are three steps: smell, see and peel.
◎ Smell: Put the coffee beans close to your nose and smell them deeply. Can you smell the aroma of coffee beans clearly? If so, the coffee beans are fresh enough. On the contrary, if the aroma is weak, or the greasy taste has begun to appear, it means that the coffee beans are completely stale.
No matter how the coffee beans are ground and boiled, it is impossible to make a good cup of coffee.
◎ Look: Spread the coffee beans in your hand, determine the origin and variety of coffee beans, and also determine whether the coffee beans are roasted evenly.
◎ Peeling: Take a coffee bean and try to peel it by hand. If the coffee beans are fresh enough, they should be easy to separate and have a crunchy sound and feeling. If the coffee beans are not fresh, you will find that it seems to take a lot of effort to stir a bean.
Another important point to observe when peeling coffee beans is to see if the firepower is uniform during baking. If it is uniform, the skin and inner layer of beans should be the same color.
If the color of the surface layer is much darker than that of the inner layer, it means that the baking power may be too great, which will also affect the aroma and flavor of coffee beans.
The difference in taste between big coffee beans and small coffee beans.
For the same kind of coffee, the bigger the beans, the higher the grade, the smaller the beans, the lower the grade and the cheaper the price. Of course, there are also differences in taste. The bigger the coffee beans, the more fragrant the coffee tastes. However, except for high-grade coffee, the classification level of other coffees is not very strict. For example, central beans can account for 60%. Then beans one grade higher than this level and beans one grade lower will each account for 20% at the same time. So sometimes, according to the standard of the marked central grade, another 40% coffee can't be roasted under the best conditions.
Division and market time of new beans and aged beans in coffee beans
The taste of new coffee roasted with the same variety and degree will be obviously different from that of old coffee. Of course, new beans are more fragrant. Although the new beans will lose a lot of water and turn white after several years of storage, the fragrance will not be greatly affected.
Coffee practice
1 first grind the coffee beans into powder.
Put it in the coffee pot.
Cook until 9 minutes full.
If there is no coffee pot, brew it with filter cloth.
Methods: Coffee powder was put into the filter cloth and brewed with 90-95 degree boiling water.

Question 6: How to choose coffee? Instant coffee is harmful to your health.
When we grow our own coffee, we know that instant coffee is the worst. The reason is very simple. The god who grinds it into powder can't see whether it is good or not.
In addition, instant coffee is baked first, then ground into powder, and then filled with n kinds of additives before being sold.
Anyone who knows a little about coffee knows that coffee oxidizes quickly after baking, and oxidizes faster after grinding into powder, because the surface area will increase by hundreds of times. After coffee powder comes into contact with air for 3 hours, the aromatic substances in it will run out. This is why we need to add a variety of additives, so the taste of a packet of instant coffee does not depend on the coffee raw materials, but on the formula of additives. So 70~80% of what you drink is actually an additive instead of coffee, and the cup that comes out can only be called coffee-flavored beverage, not coffee.
Why is it harmful to health? There is a simple reason. There are many additives. What will happen if you drink too much? You know that. ......
For a simple example, to make coffee smooth, you need to add a smoothing agent, but how do you know it won't be talcum powder?
Whole coffee beans are used for grinding, bad beans are used for instant, and the rest of good beans is used for grinding. Otherwise, why don't cafes just entertain guests with instant coffee?
Question 7: Coffee bean selection technology, how do novices choose baked beans 1? What kind of coffee utensils do you use to make coffee?
You'd better tell the clerk what kind of coffee brewing method you use. In this way, the clerk can recommend the right coffee beans for you. In addition, maybe you can share your experience with the clerk.
2. Your favorite coffee flavor.
Describe to the clerk what flavor of coffee you like. It doesn't have to be as professional and relaxed as a professional coffee tasting, such as strong or sour taste. In this way, the clerk can recommend the most suitable coffee to you according to the taste characteristics of his own coffee. Baidu/sogou Zhuhai Baifu
3. Know the taste of coffee beans before buying.
Although the coffee bean itself will have obvious regional characteristics, in the roasting process, the roaster may make adjustments according to his own understanding of the taste of coffee, and finally the taste of the same coffee can present a variety of faces. Before buying, know the taste of coffee beans. Maybe, then you can understand why the same coffee beans have different tastes when bought in different places.
4. Learn to ask the baking date of coffee beans.
As a kind of food, coffee beans naturally have "shelf life" and other indicators. Coffee beans are similar to seafood, the fresher the better. The index to judge freshness is "baking date", and it is recommended to buy coffee beans within two weeks of baking date. Because different coffee beans and different baking degrees will affect the drinking period. For example, coffee beans roasted in the middle and deep places can only be drunk after seven days of roasting, and the best taste is two weeks later, because there is a strong smell of smoke and fire. Light roasted coffee beans can be drunk in two or three days after baking, and the best flavor is after one week, and the variability of bean flavor can be drunk. Both of them are best drunk within one month. After buying home, you can write the date of baking beans on the package with a strange pen, which can help you understand the freshness of beans.
But many people will say that it tastes good when it is tried on the spot, and it tastes bad when it is bought home. It should be affected by the following reasons: first, the particle uniformity of household soymilk machine is different from that of commercial soymilk machine, especially the difference between manual and electric soymilk machine, and the uniformity and thickness of electric soymilk machine can not be obtained manually; In addition, the water quality selected by some coffee shops may be relatively superior to the domestic water quality; Thirdly, material, the pressure index and stability index of different price models in italian coffee machine are different, which will affect, for example, the material of filter cups, the material of hand-cranked pots and so on.
Buy whole coffee beans
Basically, shops will provide free coffee grinding service, that is, they can help customers grind whole coffee beans into coffee powder for free. If you want to fully enjoy the aroma of a cup of coffee, it is recommended to buy a WholeBean. The most attractive thing about coffee is its aroma, and in the life of coffee, if we want to select the "time list with the strongest aroma", the grinding process must be on the list, even in the top three. In addition, from the perspective of preservation, whole coffee beans have much stronger vitality than coffee powder, and whole coffee beans can maintain aroma for a longer time. If you often drink coffee, why not buy your own coffee grinder, whether manual or electric, which can not only enjoy the fun of making, but also better enjoy the aroma and taste of coffee? Why not?
Question 8: Teach you how to choose the coffee that suits you. It is said that the best coffee is freshly ground black coffee! I think it's good to find a cup that suits you. Cappuccino is the most common fancy coffee. Many people who don't know coffee know that there is a strange phenomenon. Many people will choose a cappuccino first when they start drinking coffee, or because cappuccino is delicious, the cream on coffee is still very attractive. Sit leisurely in the cafe, order a cup of coffee and savor it. Don't underestimate a small cup of cappuccino, it has many flavors, such as cinnamon, dried lemon slices and coffee with whipped cream! Just as cappuccino is rich in many flavors, people who like to drink this kind of coffee also hope that their lives can be colorful and unforgettable! Order a strong cappuccino and browse the surrounding scenery while drinking. I think there should be many cappuccino lovers who have the same philosophy of life ―― life is for happiness, and they don't want to sacrifice everything for work, and they don't like serious life. They go wherever they have fun. They are absolute hedonists. Cappuccino is suitable for people who are new to coffee. Most people who like cappuccino are lively girls who like fashion trends, but they are superficial. Mocha is another fancy coffee popular with girls. It was originally named as "MochaCocaoIceCoffee". The acidity, aroma and alcoholicity of mocha coffee, together with the sweet chocolate syrup, make it a perfect neutral iced coffee, suitable for public taste. The perfect combination of mocha coffee and chocolate syrup is very delicious! In contrast, mocha has fewer patterns and tastes more like coffee, which is more suitable for gentle women who like to drink lightly. Latte is another kind of milk coffee. It's basically half milk and half coffee, so it smells like coffee and tastes as sweet as milk. The most fascinating thing is that the latte just served can see the upper part of milk and the lower part of coffee, and the boundary is obvious. Stir gently with a spoon, and the two will be mixed immediately, and it is difficult for you and me to separate. The natural coffee flavor and mellow milk flavor of latte are really unforgettable. Latte seems to have a natural melancholy feeling, which is more suitable for some elegant people to drink. Although I don't belong to this category, I like to drink a latte when I'm in a bad mood, which seems to help inspire me, and the melancholy temperament of latte makes my mood sink into my own world and feel completely my own. People with strong self-awareness will also be very suitable for this kind of coffee. People with a sweet taste and sentimental people can try this coffee. Those who drink espresso belong to heavy metal pie. Espresso, with small quantity and strong flavor, emphasizes instant pleasure and tells fanatical personality like an artist. The comprehensive coffee, which is a mixture of several kinds of coffee beans, has a vague personality, but the taste is also the most sharp and pleasing to the eye. People who taste coffee for the first time can get started. People who like to drink espresso should be resolute in everything they do, and their sensory needs seem particularly strong. They should drink the strongest coffee, the strongest wine and the hottest food, otherwise they will not be satisfied. And in order to pursue vigorous. In a life full of flavor, they often use the least resources to burst into the greatest strength, so they always walk faster than others and live harder than others. For them, "life" is as thick and bitter as strong coffee. Perhaps life is too ordinary, and you need to use strong and bitter coffee to boost your fighting spirit!
