Freshly brewed coffee has a pronounced tonic effect, so many people start their morning with it. To buy delicious coffee beans, the top 10 (rating) of the best varieties should be considered first. Many brands carefully control the quality of raw materials, so their products have remained popular among lovers of this drink for a long time.

There are many different types of coffee in the world.

Features of bean coffee

Despite the emergence of freeze-dried coffee on the market, the grain product still remains popular. There are many varieties of it. Some have a mild taste, others are quite strong. It is believed that such coffee is more beneficial for the body than freeze-dried coffee. When consuming the first, caffeine is absorbed and eliminated in just 120 minutes, and the second - after 10 hours.

Main advantages

The advantages of bean coffee include:

  • high content of essential oils, antioxidants and microelements;
  • more intense taste and smell;
  • no chemical additives;
  • Possibility of using a Turkish coffee pot and coffee machine for preparation.

Main varieties

The most common types of coffee are Robusta, Arabica and Liberica. They differ in taste, region of production and a number of other characteristics.

Arabica

This is a commonly found coffee variety in the market.

It is grown in:

  1. Honduras.
  2. Bolivia.
  3. Ecuador.
  4. Venezuela.
  5. Kenya.
  6. Ethiopia.
  7. Colombia.


Arabica is the most popular coffee variety.
Coffee bushes grow in areas from 900 m to 2000 m above sea level. Often gentle hillsides are cultivated for the plant. Good Arabica has a mild taste with a slight sourness. There is no bitterness. Due to the difficulty of cultivation, the price of the product is high.

Robusta

It has become less widespread. This variety is preferred in China and Asian countries. In Russia it is less popular.

The main suppliers of grains are:

  1. Guatemala.
  2. Vietnam.
  3. Angola.
  4. Tanzania.
  5. Liberia.

For the cultivation of robusta, areas are developed at an altitude of no more than 600 m above sea level. The variety has a high concentration of caffeine. The drink is strong and has a characteristic bitterness. Robusta trees are unpretentious and bear fruit more often, so the product is cheaper.


Robusta beans contain the highest amount of caffeine.

Liberica

This is an elite coffee that is grown in small areas of the African continent. It is almost never exported. This is due to the increased whimsicality of the variety, due to which it is not possible to obtain a large harvest. The beans are almost never used in their pure form due to their strong bitterness and high caffeine concentration. More often they are mixed with Arabica to enhance its aroma.

What determines the intensity of sourness?

Berries for elite varieties of sour coffee are produced in the highlands, where the lack of oxygen affects their ripening period, which, accordingly, increases. Thanks to longer cultivation, the berries get a richer and brighter taste. Moreover, the higher the area where coffee trees are grown, the more sourness will be felt in the coffee (if it is roasted and prepared correctly). It turns out that this feature is considered an indicator of the high quality of the drink.

The way coffee is processed can also affect its “acidity.” For example, "Washed" or "washed" processing will retain much more acid in the beans, compared to those that are processed in another way - "Unwashed" or dry method.

Roasting also creates its own sourness. Everything is simple here: the lighter the beans from roasting, the more acids remain in them, and when grinding and further preparation they pass into the drink itself. It is worth remembering that if the beans are dark during the roasting process, the coffee will be less sour, but, most likely, there will be hints of bitterness in it.

Selection criteria: what to look for

To determine the type of grains, you should first pay attention to their size and shape. In addition, when choosing, it is important to consider freshness and degree of roasting. These parameters affect the taste characteristics of the product.

Roasting

The degree of roasting affects the ratio of strength and bitterness:

  1. Light. Easy processing at temperatures +200…+220 °C. The drink made from such grains has a sweetish note. There may be a slight herbal taste.
  2. Average. Heat treatment is carried out at +225…+250°C. More often, such grains are used to prepare a drink in a machine. The coffee is moderately strong, without bitterness and with slight sourness.
  3. Dark. Treatment is carried out at +240…+250°C. The drink does not have a sour taste, but caramel notes are noticeable. There is a bitter aroma. The raw material acquires a dark shade with a characteristic shine.


Coffee beans have different degrees of heat treatment.

Freshness

The highest quality grain is roasted no later than 2-3 weeks after harvest. It has better taste characteristics and a rich aftertaste.

Beans that were roasted no later than 3-4 weeks after harvest are considered good. Processing from 2 to 5 months is acceptable: then the taste is less pronounced.

Grain size and shape

Arabica is distinguished by its oblong grain shape and S-shaped longitudinal stripe. Robusta grains are smaller. They have a round shape. The line on the cotyledons is more even.

Coffee machine or Turk

The beans often contain instructions on the best way to prepare the drink. More traditional is the use of Turks. However, modern geyser coffee machines can be used to prepare a high-quality drink. It is believed that Arabica is better suited for this method.

Top producing countries

The coffee tree is a heat-loving and rather whimsical plant, so it is grown only in countries with a tropical climate. The taste of the drink is affected by the chemical composition of the soil and the altitude of the area above sea level.

The highest quality raw materials are collected in:

  • Ethiopia;
  • Kenya;
  • Mexico;
  • Panama;
  • Colombia;
  • Tanzania;
  • Ecuador.

Additional Information

A coffee pH value between 4.85 and 5.1 is considered average. At the same time, a product with this indicator will seem sour to most people. To reduce the richness of the taste, use the advice of experts:

  1. Use coarsely ground raw materials for brewing espresso.
  2. When cooking in a Turk, boil its contents for a minimum time.
  3. Keep the coffee in the French press for no more than 3-4 minutes.
  4. To infuse in a cup, choose the finest ground grains.

You can emphasize or neutralize the taste of coffee by drinking it with desserts. For example, espresso, Americano and ristretto have a bright taste and moderate bitterness. In order not to interrupt their aftertaste, you can serve the drink with chocolate brownie, marzipan, nuts or dark chocolate without additives. Multi-ingredient or berry desserts, on the contrary, hide the natural sourness of coffee.

Dairy options - latte, raf, cappuccino - are quite sweet. Desserts with a slight sourness are perfect for their delicate taste. A good addition would be cakes with moderately sweet berries - currants, lingonberries or raspberries, cakes with nuts or French macarons. The classic version is cheesecake with a curd base and sliced ​​cheese. Desserts that are bitter or too sweet are not recommended to be consumed with any type of coffee.

Rules for preparing coffee beans

To make coffee, you first need to grind the beans, which should be done immediately before brewing, because... This will help preserve the taste and aroma. If the drink will be prepared in a Turk, you need finely ground coffee. The water must be purified, i.e. without chlorine impurities.

The ground product and liquid are taken in a ratio of 1:10.

First, put ½ water and coffee in the Turk. Then put the mixture on the fire and wait until bubbles stop appearing on the surface. After this, add the remaining water. Continue brewing the drink without bringing it to a boil. After 2-3 minutes, pour it into a heated cup and leave for 2-3 minutes for the grounds to settle.
