Liberian caffeine content-caffeine content of a cup of coffee

Liberian species, scientific name Coffealiberica), West Africa is the origin of Liberian coffee, no matter high or low temperature, humid or dry and other environments, all have strong adaptability, but not resistant to leaf rust, flavor is worse than Arabica robusta species, scientific name coffee RobustaLinden, leaf rust resistant varieties found in Congo, Africa, have stronger resistance than Arabica species. In fact, it was a mutant of the Congo species (scientific name Coffeacanephora). The name of the Robusta species has become popular, and it is regarded as the same species as the Congolese species. This has a unique aroma (called "Luobu smell", which some people think is moldy) and bitter, and is generally used in industrial coffee, such as instant coffee, bottled coffee, liquid coffee, or in a small amount in blended coffee. Caffeine content of about 3.2% of the acabica species, scientific name coffee Arabica, origin is Ethiopia's Abyssinia plateau (now Ethiopia plateau), initially mainly used as medicine to eat, the 13th century to develop the habit of baking and drinking, the 16th century through the Arab region in Europe, and then become a common favorite drink all over the world. The resistance to nature's dryness, frost, diseases and insect pests is too low, especially the natural enemy of coffee-leaf rust. Arabica is mainly produced in South America, Central America, Africa (East African countries) and Asia (including parts of Yemen, India and Papua New Guinea). Caffeine content about 1.5% Coffee has always been thought to have certain effects, such as strengthening the stomach, waking the brain, stopping bleeding, dissipating heat, strengthening the body and so on. Current studies have found that there are about 103 species of coffee, including Arabica and Robusta (with Liberian species, these three are the "three major native species, traded only within West African countries," or planted for research. ). The Canifera species is commonly known as the Robusta species. In fact, the Robusta species is only a branch of the Canifera species, because it is widely recognized, so the Robusta species has gradually become synonymous with the Canifera species.

1. Raw coffee beans

Coffee fruit has been refined enough to be used as a commodity circulation of coffee seeds.

two。 Lao Dou (old crop)

Raw beans that have been harvested for more than a year and have less water content. Those listed in the same year are "new beans", and those listed the following year are "old beans".

3. Defective bean

Refers to bad coffee beans mixed like raw beans. Including dead beans, unripe beans, shell beans and so on. Failure to pick out defective beans before and after baking will destroy the taste of coffee.

4. Flat bean (Flat Bean)

In the general coffee fruit, there will be two coffee seeds growing relative to each other, and its contact surface is flat, so it is called "flat bean".

5. Round bean (Pea-berry)

When the coffee fruit is not fully developed, there is only one coffee seed in the fruit, which is round in shape, so it is called round bean.
