How to tell the robusta coffee beans? What does Luo Dou look like?

The first chapter of the Coffee Taste Collection, the basic knowledge of coffee beans, the first section, the three native species of coffee.

2. Robusta species (scientific name Coffee Robusta Linden). P8 (Note p8, which indicates page 8, is annotated in many places).

Robusta coffee beans are generally used for instant solution because they extract twice as much coffee liquid as Arabica.

The caffeine content is 3.2%, more than twice that of Arabica, and 1.5% of Arabica.

How to tell the robusta coffee beans?

It's not in the book. I think there are three points worth noting. The first is the size, shape and shape, and the second is the grain in the middle and edge of the bean.

The third is cooked beans. Eat them directly and taste them.

The difference in appearance between Arabica and Robusta coffee beans

The picture compares the shape difference between Arabica and Robusta coffee beans.

The appearance of Arabica coffee beans is quite obvious compared with that of Robusta coffee beans. Arabica coffee is long, flat, complete and greenish; robusta coffee is round, thicker and whiter.

The following information from Baidu is for your reference:

Robusta is one of the most important coffee tree varieties in the world. Robusta species (scientific name Coffee Robusta Linden). The leaf rust-resistant varieties found in Congo in Africa have stronger disease resistance than Arabica. In the general coffee market, many people like to compare robusta and Arabica coffee beans, which is incorrect. In fact, the Robusta species was originally a mutant of the Congo species (scientific name: Coffee Canephora), and it should be compared with the Alabica species. Today, however, the Robusta species is commonly used by ordinary people, and it is not known that it is actually a variant of the Congolese species. Arabica coffee beans grow at colder high elevations in the tropics, and those high temperatures and low elevations that are not suitable for Arabica are the land of Robusta. Robstado grows in the lowlands at 200-600m above sea level and likes warm climates. the temperature is 24-29 ℃, and the requirement for rainfall is not high. However, the variety depends on insects or wind to pollinate, so it takes 11 months from pollination to fruit, which is longer than the Arabica species. Robusta kind of Ken has a unique aroma (known as "Rob flavor", some people mainly moldy smell) and bitter taste. If 23% of the coffee is mixed with other coffee, the whole cup of coffee will become Rob flavor (therefore, Robusta coffee beans can not be drunk as individual coffee beans). Its flavor is so bright and strong, but if you want to taste it directly, you have to be prepared. In general, robusta coffee is used in instant coffee (which extracts about twice as much liquid as Arabica), canned coffee, liquid coffee and other industrial coffees. Its caffeine content is much higher than that of Arabica, about 3.2%.

The title of this article (w.kaf.name): "how to identify Robusta coffee beans?" What are the characteristics of Robusta coffee? Reading notes. "

The coffee tree planted by Robusta is a kind of tree between shrubs and tall trees. Its leaves are long and bright green. The tree can be up to 10 meters high, but its roots are very shallow. The fruit is slightly rounder and smaller than Arabica coffee. The bean body is flat and round. The middle pit is straight. (http://blog.sina.com.cn/s/blog_6261cecc0102e1qw.html) robusta accounts for 25% Mel 35% of coffee bean production, and its main producing country is Indonesia. (one of its coffee beans is processed by washing, and it is a hybrid between Robusta and Arabica. It is the only coffee bean on the Chinese market that can be used as a single drink), Vietnam, Africa, (Ivory Coast, Nigeria, Angola as the center of the West African countries), Vietnam has been more committed to coffee production in recent years, and included it in the national policy (Vietnam also produces a small number of Arabica coffee beans).

Arabica vs Robusta

In many places where coffee is sold, it is not difficult to find words like "100% Arabica". Even canned coffee appears in a style called "XX Arabica Coffee", which makes one wonder: what is "Arabica Coffee"? In fact, Arabica is the name of the coffee tree variety (species).

"Coffea Arabica" and "Coffea Robusta" are two different coffee varieties, which currently account for the vast majority of coffee bean production in the world. There are three main differences between Arabica coffee and Robusta coffee: 1. Differences in planting conditions. two。 The flavor and characteristics are different. 3. The difference between market price and use.

Planting condition difference

The planting conditions of "Arabica" coffee are relatively stringent, requiring higher elevations (6 to 2000 meters above sea level), fertile soil fertility, adequate moisture, proper sunshine conditions and shade. "Arabica" coffee species are less resistant to diseases and insect pests and are vulnerable to damage. In addition, the annual output of coffee trees per unit area is also lower.

Currently, "Arabica" coffee accounts for 75% of the world's coffee production, and of these "Arabica" coffee production, only 10% of Arabica coffee quality can be classified as "boutique coffee (Specialty Coffee)."

"Robusta" coffee, commonly known as "sturdy beans", can be grown at low elevations (200 to 800 meters above sea level), has strong resistance to diseases and insect pests, is not vulnerable to agricultural disasters, has a high annual output per unit area, and is harvested in large quantities by machine. in general, the cost of production is much lower than that of Arabica coffee.

Different flavors and characteristics

Arabica coffee has a varied and broad potential flavor. Arabica coffee produced in different regions, different elevations and different climates usually has its own characteristics and can show a completely different flavor. "Arabica" coffee smells like grass when it is not roasted. After proper roasting, it shows "fruity" (medium-light roasting) and "caramel sweetness" (deep roasting). Generally speaking, it has a better aroma and flavor than Robusta beans.

"Robusta" coffee usually has an ordinary, rigid and pungent flavor, and because the vast majority of robusta around the world are grown in low-altitude areas (author's note: as of May 2008, only India has rare high-altitude, high-quality, washed Robusta coffee beans). The flavor produced by different regions and different climates is not very different, relatively lack of personality. When unbaked, it smells like raw peanuts, and the taste of cheap robusta coffee beans is usually between "wheat tea" (light baking) and "rubber tire flavor" (deep roasting). It is difficult to show a meticulous flavor.

The title of this article (w.kaf.name): "how to identify Robusta coffee beans?" What are the characteristics of Robusta coffee? Reading notes. "

Difference between market price and use

High-quality Arabica coffee requires complicated manual picking, selection and meticulous processing, so the world's most expensive and best coffee beans are Arabica coffee. "Robusta" coffee is usually used to produce instant coffee and canned coffee because of its low cost. A small number of better quality "Robusta" coffee are also used in mixed coffee (with Arabica coffee) espresso beans.

Other differences

There is another important difference: the amount of "Caffeine" (C8H10N4O2). Robusta coffee contains about twice as much caffeine as Arabica coffee, which is why drinking some canned coffee is prone to palpitations and insomnia.

After seeing so many differences between Arabica Coffee and Robusta Coffee, it must be emphasized finally.

"Arabica coffee" is not the same as "good coffee", "Robusta" is not absolutely cheap coffee!

Arabica coffee accounts for 75% of the world's coffee production, and its quality varies widely, from good to bad. In recent years, a few countries (such as India) have devoted themselves to improving the quality of robusta coffee. They have planted robusta in high altitude areas, given the most careful care, and carefully washed the coffee. As a result, they get very good quality robusta coffee beans! Top Robusta beans are not cheap either, getting rid of the old impression that Robusta are cheap beans! Therefore, the quality of coffee beans can no longer be judged by the crude and outdated ancient criterion of "Arabica beans".

Robustas... The Awakening Specialty Coffees?

Robusta coffee... Awaken the boutique coffee?

Speaker: Pierre E. Leblache, founder of the World Robusta Grinding Coffee Alliance

Tea and Coffee World Cup, Singapore, October 10, 2004

Good morning! Ladies and gentlemen,

Time is so fast. It was like yesterday two years ago. At the World Tea and Coffee Festival held in Kuala Lumpur in 2002, we spoke to each other.

The development of Robusta coffee exchanged views and views: at that time, the prospect of all coffee was very bleak, and the price of Arabica coffee was only 58 cents, Biro.

The price of Busta coffee is less than half that. At that time, we were at the lowest point of the price cycle, and we expected things to improve.

It is hoped that millions of coffee growers around the world will soon improve their living standards. At that time, we hoped that the price of Arabica coffee could really rise.

Expectation: the price of light coffee can reach more than 80 cents per pound. We plan to increase the price by 40% in 2 years. Related products are in production.

And cost and many other important factors can be effectively improved. Unfortunately, the price of robusta coffee has not changed after two years.

The price of a pound of weight is close to the price of a pound of Arabica coffee.

The well-known reasons have not changed much: overproduction, inappropriate drying processes have affected the quality, and some low-grade dissolved mixtures

Methods, lack of ascension, and total lack of awareness all create a very bad impression, or there is no image at all.

For most Robusta coffee, the future outlook is very bleak, and many varieties will disappear in the next few years. On the contrary, the Robusta Cafe

More excessive production, fewer and fewer exports, and eventually a shutdown, which has now occurred in some of the larger producing countries.

There have been two or three such cases. There are five countries in Asia, Laos, Cambodia, Bhutan, Nepal and Myanmar, which suddenly become important.

Exporters of robusta coffee are like Vietnam, which became a nouveau riche in the 1990s.

Over the past 15 years, there have been three major events in 1989, 1992 and 2001, and prices have fallen sharply, not only for robusta coffee.

In the same way, Arabica coffee can't escape bad luck. It may be said that all these things are bad things, but there is also a bright side. Like in 1989, the market

The turmoil has led to the emergence of boutique coffee. At that time, some creative and realistic manufacturers realized that there was only one way to change.

To change the volatile depressed price market. That is to follow the route of quality, awareness and customer loyalty. Frankly, we benefit from the United States

More and more people began to get tired of the steaming black liquid and instead shifted their focus to the coffee bean mill.

It's in the ground coffee. At that time, in many coffee shops, one pound of coffee beans could produce 200 cups of delicious coffee.

Instead of the past 50 cups of 1-pound coffee beans, the result is: steaming black liquid, actually no longer black.

Since then, the number of consumers of high-quality coffee has grown from only a dozen to millions, and the market for coffee made from coffee mills has

It's booming. More than 20 coffee growing areas are involved, some with only a few hundred bags and some with millions of bags. To the producer

In terms of quality coffee, there are more than 150 types and a variety of names. For consumers, there are more than hundreds of brands.

By the year 2000, the world of coffee had changed intricately. At the beginning, only a small portion of Robusta coffee entered according to the process of washing coffee.

OK, processing. The color is inconspicuous, and the biggest question is whether it makes people think that such a practice is worth considering. Some countries do produce washed robes.

StarCoffee, such as India and Uganda. These two countries are also exporters of Arabica coffee, and they believe that Robusta coffee is

Worse varieties, it is not worth the effort on them. The Elk Hill plantation in southern India is rich in a kind of watered coffee called Raigode.

Caffeine, full granules, no defects. Such beans have become the main source of robusta coffee made from coffee bean mills. Although some advance

Mouth merchants are willing to turn Kaapi Royale into the standard of fine coffee, but Raigode is still undoubtedly called essence in the consumer group.

The symbol of the coffee market. Raigode has been a success, and its price is quickly close to that of Arabica coffee in India. Some Indian manufacturers have entered

Taohua / library for special use

Several trades have been done, and the batches are very small, but the method is appropriate. The smallest number, but this is not an obstacle to the grind coffee trade: high-end consumer requirements

Different, the market volume is not large, there are hundreds of kinds required. In Italy or the United States, through some small boutique coffee roasters, ten

The transaction of a few bags of coffee can reach a high transaction price.

The market for washed robusta coffee is constantly expanding, and in the past two years, these similar situations have occurred in Ecuador, Madagascar and Brazil.

Other countries, such as Uganda, Cameroon, Mexico and even Guatemala, are also planning. In Mexico, Robbs.

Tower coffee may account for 8-10% of total coffee crop exports, until recently banned. In Guatemala, Robusta coffee accounts for coffee production.

The total amount is less than 1%, and its existence is almost negligible.

Now, you may ask, there are so many Arabica coffee in the boutique market, why do we need Robusta coffee to participate?

The answer is the same: difference, the truth is this. High-quality, well-processed robusta coffee is far better than ordinary or even no pass.

Well-processed Arabica coffee. Fifteen years ago, only the best, carefully selected and processed coffees were allowed in the boutique coffee market

Coffee. With the continuous growth of the market, some coffees marked with Arabica Coffee are considered to be ground coffee. Some days

I saw the sign "Fancy Gourmet Arabica Soluble..." on the can. There are no other comments. "Fancy" is a "fake"

The high-sounding explanations of the words "fake" and "fake" are ridiculous. This is not what every coffee lover likes. The problem is, in the past 10

In 2000, this situation is not so frequent. (http://blog.sina.com.cn/s/blog_6261cecc0102e1qw.html)

Another reason for the entry of high-quality robusta coffee into the boutique market is its price advantage. When the consumer group begins to expand, people

We began to notice not only the taste, appearance and smell, but also the price. Because there is a big difference between the two kinds of coffee

Different, Robusta coffee made from coffee bean mill can greatly reduce the price compared with his brother mild coffee, so introduce

Arouse the attention and needs of consumers.

The title of this article (w.kaf.name): "how to identify Robusta coffee beans?" What are the characteristics of Robusta coffee? Reading notes. "

We found that in 2002, more than a dozen institutions, groups and colleges that specialize in coffee research did not turn their attention to Rob Taka.

Come on, come on. In fact, we can exchange ideas on Robusta coffee, discuss its use, improve its quality, and find ways to raise its price.

Grid. This prompts us to set up the World Robusta Grinding Federation, which aims to change the fate of Robusta Coffee and upgrade it.

The space for development. To be more precise, we will continue to achieve our goals by:

Throughout the field of ground coffee, an ideology has been established to make people aware of the existence of a different boutique coffee. This

Coffee is the same in quality and characteristics. We need to actively and effectively let people find that a small amount of Robusta grinded coffee already exists.

-promote the sales of boutique coffee and all aspects of the production chain to maintain its price advantage.

-develop more varieties in the country of origin, raise the standard of grinding and washing coffee, and improve the process of washing.

-produce some boutique Robusta coffee varieties as soon as possible and promote and display them in some ground coffee activities.

By the end of 2006, a special event for grinding robusta coffee could be held.

-to explore some other countries where robusta coffee is produced.

-promote the Robusta Coffee Promotion Project through government agencies, organizations and some private companies in the areas of production, processing, marketing, etc.

Consulting and mentoring work

-build a communication bridge between buyers and sellers, quickly find resources and ways out, and accelerate the performance of Robusta coffee in the boutique market.

Taohua / library for special use

I am very pleased to tell you that we have made good progress in the above points, and in some areas we have seized the opportunity. For example, for a few weeks

After that, the first Robusta Coffee event will be held in Vit ó ria, Brazil, where they produce Robusta coffee. We know.

Many of you will be there to attend the event, and I would like to congratulate you.

In addition, there is a lot of good news, which we have mentioned earlier. Vietnam, the world's leading exporter of robusta coffee, is

In planning to enter the field of grinding Robusta coffee, they are looking for opportunities to create eye-catching brands and types. For this coffee,

For the giant of production, the production of ground Robusta coffee accounts for only 2% or 3% of its output. Vietnam's grinding Robusta coffee market

Possession will develop rapidly, just like El Salvador. A huge wave...

The title of this article (w.kaf.name): "how to identify Robusta coffee beans?" What are the characteristics of Robusta coffee? Reading notes. "

Asia is the home of robusta coffee. There are six largest exporters of robusta coffee in the world, including three in Asia, accounting for the world's total output.

2, 2, 3. Compared with other regions, Asia has more gains and losses, not only in terms of price, but also in the image of Robusta coffee.

Aspects. India has great potential to influence these factors. Some of the new producing areas that I mentioned earlier, Laos, Cambodia, Nepal and Myanmar

Home, if their output becomes noticeable, they will only be competitive in the market and have a small reputation. When

When the world consumes more and more ground coffee. Robusta Coffee will have great potential for the diversity of ground coffee.

In this world, the face of coffee has changed, and we can see all kinds of good situations: the decision of the United States to rejoin the ICO is a good sign.

But American lawmakers have made it very clear that they demand a tax-free market and that the price terms cannot be reversed. Robusta Coffee Plantation

In their own hands, countries that have joined the boutique coffee trade are growing. There is a French proverb "Aide toi, le Ciel t'aidera", which means

"God helps those who help themselves". Now may be the best time to start.

We will be very happy to discuss this topic with you here, thank you!
