Coffee ... How much in this word. The whole world was conquered by this invigorating drink with an incredible aroma. Coffee is a whole art that you never get tired of learning. Many subtleties and secrets lurk in the process of its preparation, which every coffee lover needs to know about. In order for a freshly brewed drink to fully meet expectations, you need to know about the rules for choosing these beans.
Features and composition
Coffee beans have a unique and complex composition, which includes 1200 components. The composition of this product continues to be studied, as well as the effect of these components on the human body. An interesting fact is the appearance of some components in coffee beans during heat treatment.
Most of the constituent elements are aromatic substances and volatile compounds. That is why bean coffee has such a strong and unique aroma. These volatile compounds largely determine the taste characteristics.
The main component of which the coffee bean is composed is caffeine. It is he who gives cheerfulness and a charge of energy.
Different varieties contain different amounts of this component. The more caffeine, the more expensive the coffee. Also, the caffeine content depends on the degree of ripening of the grain and the duration of its roasting.
Grains also contain B vitamins, which are necessary for our body to function properly.There are other vitamins in grain coffee: A, D and E. In addition, the grain contains acids, amino acids and proteins that are important for humans.
If there are no additives in coffee, including sugar, then the number of calories is minimal. Such a product is quickly and easily absorbed by the body. Despite such a pleasant feature, you should not drink more than two cups of this drink per day, because it contains a large amount of caffeine, which in large quantities can harm the body.
Benefit and harm
Everyone will be interested to know how useful grain coffee is and what is its harm to our body. Let's start with useful qualities.
- The presence in the composition of a huge number of useful components, many of which are necessary for the normal functioning of our body.
- Increasing attention and stimulating memory.
- Mood boost, due to which freshly brewed coffee is recommended in the initial stages of depression.
- Strengthening the action of certain medications, for example, analgin and acetylsalicylic acid. This effect of caffeine primarily extends to painkillers.
- Reducing the likelihood of developing Alzheimer's disease and Parkinson's disease. This is due to the effect of caffeine on brain neurons and the presence of a vasoconstrictor effect. The brain and vascular system receive a kind of training that hardens them.
- Reducing the likelihood of constipation and getting rid of an already developed problem.
- Prevention of the formation of pathologies that affect the liver.
- Prevention of breast cancer.
The harmful effects are as follows.
- Development of coffee or caffeine addiction, which is comparable to nicotine or alcohol. Dependence is manifested in a decrease in the effect of caffeine exposure. The body not only requires constant consumption of coffee, but also an increase in its amount.
- Diuretic effect of short duration. If you drink a lot of coffee, then dehydration of the body may occur, which will be accompanied by leaching of useful trace elements from the body. After a cup of an invigorating drink, it is recommended to drink a glass of water.
- An increase in pressure is especially dangerous for hypertensive patients. One cup of blood pressure can increase by 15 units. If a person has heart pathologies and problems of the vascular system, then this figure may be higher. But for hypotensive patients, a cup of coffee can bring blood pressure back to normal.
- Regular consumption of unfiltered coffee can increase blood cholesterol which is a dangerous situation. In this condition, the likelihood of developing a stroke or heart attack increases significantly.
- Decreased bone density typical for older people who drink coffee in large quantities.
- High risk of development urolithiasis.
- Coffee is contraindicated for pregnant women, because it can negatively affect the fetus (anemia of the placenta, miscarriage, low weight gain).
- Stimulating the heart and increasing the load - the indirect effect that the drink has on the body. If caffeine enters the body a lot, then the effect on the heart will be detrimental.
Subject to the norm, the situation will not go beyond the safe border.
Appearance
High-quality coffee beans must meet a number of requirements that apply to its appearance.
Natural coffee fat should be on the surface of the beans.This feature makes the grains look like wet. The presence of this fat indicates the high quality and freshness of the product. Arabica beans are larger than Robusta. Another distinguishing characteristic is the S-shaped groove in the center of the bean, which is unique to Arabica.
The grains in the blend must be whole, have the correct shape. The presence of halves and crushed elements in high-quality coffee is unacceptable. Such small particles are quickly roasted and charred until the whole grain reaches the desired degree of roasting. Such coffee will be very bitter and have an unpleasant aftertaste.
The color is uniform and the same not only in the area of \u200b\u200ba separate grain, but in general in all beans. The presence of lighter beans among the dark ones indicates an early harvest of coffee that did not have time to ripen. To the touch, high-quality grain has a velvety texture.
Roast level
The level of roast for coffee is of great importance. This characteristic determines the taste of the future drink, its aroma and color. Unroasted coffee beans are green in color. During heat treatment, color, taste, aroma and other characteristics change.
There are 10 coffee roast levels. This information must be indicated on the label by the manufacturer. Next, we will find out which coffee roast degree is more suitable for different taste preferences.
The light degree of roasting is obtained as a result of a short heat treatment. There are several varieties of roasting.
- Scandinavian involves languishing beans at low temperatures. The grain increases slightly, but does not open.With this treatment, the grains acquire a delicate aroma, in which there are notes of smell emanating from fresh bread.
- American roasting endows the grains with a light brown tint and an inexpressive taste.
- city degree roasting makes green beans dark brown and adds a spicy sourness to the taste.
- Universal roasting or medium is the best option for most coffees. There are also different degrees here:
- Full urban suggests the presence of a second cotton, the release of oily drops on the surface of the grains. The drink in this case is incredibly aromatic and slightly viscous.
- French degree also called velvet and viennese. Roasting occurs until the grains acquire a rich brown color. During the heat treatment, smoke appears above the coffee, which comes from the burning oils contained in the beans. The finished drink is bitter, strong, with a rich taste and strong aroma.
- Dark roast also called Mexican, Spanish and Cuban. These grains contain a very small percentage of water. Blends are created from such coffee and new tastes are discovered.
- Italian roast involves intensive heat treatment and air treatment. The beans are then left in the open air, which allows carbon dioxide to escape freely from the grains. Such a product requires special packaging (paper, foil bag), which does not allow coffee to oxidize and lose its taste characteristics. This roast is perfect for espresso.
Producing country
The characteristics of coffee are greatly influenced by the conditions of its growth. Therefore, you need to pay attention to the country in which the beans were grown.
Brazilian coffee is in first place in the world ranking. This country grows the largest number of beans. The taste of a drink made from such grains will be simple, without additives and extra notes. This is what distinguishes Brazilian coffee and makes it valuable among gourmets. Coffee from Guatemala has hints of spice in its palate, which makes it special.
Ethiopia is also actively growing coffee and supplying it to the world market. In such grains there is sourness, a hint of cinnamon and the taste of wild berries. The taste of the finished drink is interesting, soft and special, as evidenced by numerous reviews.
The best coffee in Africa comes from Kenya. Coffee cultivation is controlled by the state, which guarantees its high quality. Kenyan beans are characterized by light sourness and notes of blackcurrant, which makes the finished drink flavored and noble.
Coffee from Colombia is characterized by lightness and fruity notes that are well felt in the finished drink. The Indian product is distinguished by a special aroma, in which there is strength and expressiveness.
Beans from Yemen are characterized by a pronounced fruity taste, which not all gourmets like. But there are a large number of users who choose this coffee precisely because of this peculiar taste.
Although Cuban coffee is not as popular as Colombian and Brazilian coffee, its excellent taste is appreciated by many lovers and gourmets.
Mexico grows exclusively Arabica. The grains are large in size and mild in taste.They make a not very strong drink, which has a large number of admirers among lovers of weak coffee.
Ecuador grows three varieties of coffee: Arabica, Robusta and Liberica. The product is upscale, although a few decades ago coffee from Ecuador could not even be classified as middle class. Most of the crop remains in the country, only 20% is exported.
Varieties
Taste characteristics and a number of biochemical properties of the product depend on the variety and blend. It is not the brands and marketing legends that are located on the packages, but the varieties and the ratio of grains that matter. About 90 varieties are known to the world, but only two of them are produced on an industrial scale.
Arabica is the most expensive and widespread variety. Plantations of such coffee occupy up to 90% of all plantations. Approximately the same amount is contained in many blends. Aroma and taste come first, not strength and caffeine content. Arabica is the best coffee grown on plantations around the world.
Robusta is not as common as Arabica. It is more accessible, but not as fragrant, but very strong. The taste is simple, even a little rough. It is the Robusta grains that add bitterness and strength to the blend.
Liberica is the most affordable variety that cannot be attributed to cultural or healthy coffee. The cultivation of such coffee is carried out by manufacturers who seek to reduce the cost of their product in any way. Despite all these negative qualities, Liberica has a strongly pronounced aroma. Such grains can be added to the blend in a small amount to improve the aroma.
Green coffee is a novelty that is very popular.The user is tempted by the ability of such a product to lead to rapid weight loss, give vigor and increase efficiency. In our opinion, this is a well-thought-out marketing plan, but nothing more.
On sale it is difficult to find pure coffee varieties, without additives. Manufacturers create blends of Arabica and Robusta, varying the percentage of each variety.
Arabica 100% is the most elite variety, it is also the most expensive and rare. A freshly brewed drink from this variety will have a deep velvety taste, in which a slight sourness will be traced.
Many growers practice mixing Arabica beans from different countries. Only a true gourmet and a true professional can catch this moment. For the average lover, the taste will not be different.
- Arabica 90%, Robusta 10% - this is the most common blend of coffee, which harmoniously combines strength and taste, there is no sourness, but there is a slight bitterness. This blend is used by coffee shops to prepare a large number of drinks (espresso, cappuccino, americano).
- Arabica 80%, Robusta 20% - such a blend does not even have a hint of sourness, but it has a high strength and a pronounced invigorating effect. Latte can be prepared from such coffee, since the additional components that are included in the drink recipe reduce its bitterness.
- Arabica 70%, Robusta 30% - according to this recipe, inexpensive blends are created, which are popular in small catering establishments and fast food restaurants. If you plan to buy such coffee at home, then you need to carefully study the label for the absence of Liberica.
The blend, created on the basis of Arabica, Robusta and Liberica, stands out for its low price.Oddly enough, there are many connoisseurs of just such a product. After the low cost, an important advantage is the bright and strong aroma that appears in the blend thanks to the Liberica coffee.
How to choose and store?
Coffee reacts sharply to storage and transportation conditions. Even initially high-quality grains can be irretrievably damaged during improper transportation and storage. Therefore, you need to know about the rules and secrets of choosing this product, and you must also follow the conditions for its storage.
It is better to buy coffee by weight. In this case, you can visually assess the quality and condition of the beans.
Quality grains have a shiny surface, these are the beans you need to choose. They should not be dull or gray. Such features indicate the staleness of the product or broken packaging. Coffee in a package that has signs of swelling is stale.
Smell can tell you a lot. It should not be traced notes of rancidity, mold and mustiness. Therefore, when you are going to buy coffee, you should not use toilet water so that your sense of smell is not confused by extraneous odors.
Reliable manufacturers who care about the quality of their product equip packages with special valves. They allow you to smell the product and provide an outlet for carbon dioxide, which is released in large quantities from the grains after roasting.
The integrity of the grains must not be compromised. Each grain should be even, without chips or cracks.
You have to pay for a quality product. Good coffee cannot be sold at a low price. Grossly undervalued grains are indicative of poor quality grains, stale, spoiled, or a high percentage of Liberica.
Coffee, like any product, has a shelf life.At this point, when choosing grains, you must definitely pay attention. After roasting for only two weeks, the grains retain a full set of flavor and aroma characteristics. After this period, the grains begin to lose their features. Roasted beans, packed in high-quality packaging equipped with a non-return valve, can be stored for a year.
The packaging should contain complete information about the product and the manufacturer - when and where the beans were harvested, when they were cooked, variety, degree of roasting, and many other information. You need to carefully study the packaging design and brand. Well-known brands are often faked, while changing the letters in the name.
Now let's talk about the rules for storing coffee beans. Since this product is capricious, the wrong conditions can completely spoil it and make it unsuitable for further use.
Grains should not have direct contact with air. They quickly oxidize, lose their qualities and deteriorate faster.
Coffee perfectly absorbs odors, so it should not be stored next to products with a strong odor.
To store coffee, you must use a vacuum container that will not let the sun's rays through. On the free market there are special vacuum packaging with a multilayer structure. They are best suited for storing beans.
The grains are able to absorb moisture, which significantly reduces the shelf life of the product and loses its characteristics. Always keep the lid tightly closed and keep coffee away from water sources to prevent moisture ingress.
Heat is another enemy of coffee beans, from which they must be reliably protected.You can increase the life of coffee beans by 2 months with the help of a freezer, the product is pre-packaged in a bag.
How to brew?
Any coffee, even the most high-quality and delicious, can be spoiled if it is not prepared correctly. Even at home, you can make a high-quality and tasty drink that will not be inferior to that prepared by professional baristas.
It is necessary to follow a number of rules and secrets with which you will brew coffee like a true professional.
- At home, a Turk is often used to make coffee. It is impossible to use other dishes for these purposes that are not intended for preparing an invigorating drink. The Turk must be of high quality.
- During cooking, clean water must be used. It can be filtered or purified and always low in minerals (upper value 130 mg/l). Water with a low content of soluble components will be able to absorb more components from coffee. Poor quality water will greatly spoil the taste of the drink.
- Before using the grains, it is better to fry them a little in a pan. Such a secret will make the drink more aromatic and rich.
- Grinding of grain is determined by the method of preparation of the drink. For example, for the Turks, the finest grinding is needed, and for the press, a larger one is needed. With fine grinding, the drink from the Turks will have a thick, viscous and rich taste. Coarse grain in the press will not cause boiling water to splash out.
- Grinding of grains is carried out only before cooking. To do this, it is better to buy a burr manual coffee grinder. With its help, you can obtain the required degree of grinding.
- If you are a true admirer of coffee, but the long process of cooking in a Turk does not suit you, then it is better to buy a special machine. Coffee home installations are now available in a large assortment and finding a suitable model is not difficult. With them, the process of preparing a drink turns into a special ritual that brings pleasure.
- Beginners who are just starting to master the art of making a fragrant and invigorating drink should not experiment with dosages and ingredients. Until the classic recipe is perfected, you will have to be patient.
The secrets have been sorted out, you can proceed to the cooking process. There are five ways to do this.
- With the help of a Turk, which is also called cezve or ibrik. This method is the oldest and consists of several stages.
- A teaspoon of ground coffee with a slide and sugar are poured into the Turk.
- We pour water into the Turk and put it on fire or in sand, if a special apparatus is used.
- We are waiting for the foam to rise. At this point, the Turk is removed from the fire.
- The foam should settle, after which the Turk returns to the fire again.
- So you need to repeat four times. It is very important not to break the structure of the foam, this is the main rule for making coffee in a Turk.
- Chemex - a unique and at the same time simple device. With it, you can prepare a drink in any conditions and anywhere, and not just at home. To work with Chemex, you will need four-layer filters, coffee and hot water with a temperature of 95 degrees. The essence of preparation is as follows.
- In a clean Chemex, we lay the filter in expanded form so that one layer is located on one side, and there are three layers on the other.
- Pour 31 g of coarse ground coffee into the center of the filter and make a recess.
- We heat the water to 95°C. This temperature can be achieved in two ways. Turn off the kettle or remove from heat before boiling or wait after boiling for about 10 seconds.
- Pour a little water on the top layer of coffee and wait about 40 seconds. After that, pour water in small portions, starting from the walls and heading towards the center.
- The water will slowly seep through the coffee, so be patient and take your time.
- Brewing coffee will take about 4 minutes. After this time, you can remove the filter. Chemex needs to be shaken lightly, which will allow the drink to be saturated with oxygen.
- French press greatly simplifies the process and reduces the time that will have to be spent on it. In this case, coarse ground coffee must be used.
Coffee machines are the best option for making coffee. Such installations cost a lot, but the opportunity to enjoy the excellent taste and smell of freshly brewed coffee is priceless. For a true gourmet and a true admirer of this noble drink, the high cost of a coffee machine will not become an obstacle. In such installations, a large number of coffee varieties can be used.
Professional espresso is the ultimate dream for a coffee gourmet. When using this technique, it is necessary to observe the exact dosage, to achieve uniform distribution in the filter, to monitor the observance of the gap between the grid and the tablet.
