Development status and derivation of Robusta coffee beans

Robusta: https://baike.baidu.com/item/ Robusta / 4878176?fr=aladdin

Robusta species (Latin name Coffee Robusta Linden) is one of the most important coffee varieties in the world. The leaf rust-resistant varieties found in Congo in Africa have stronger disease resistance than Arabica.

Differences in growth environment:

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 200-600m above sea level and likes warm climates. the temperature is 24 ℃, and the requirement for rainfall is not high. However, this variety depends on insects or wind to pollinate, so it takes 11 months from pollination to fruit, which is longer than the Arabica species.

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. Its caffeine content is much higher than that of Arabica, about 3.2%. Robusta has a unique aroma (known as "Rob smell", which some people think is musty) and bitter. If 23% of the coffee is mixed with other coffee, the whole cup of coffee will become Rob flavor (therefore, Robusta coffee beans are generally not drinkable as individual coffee beans). Robusta coffee is commonly used in instant coffee (which extracts about twice as much liquid as Arabica), canned coffee, liquid coffee and other industrial coffees. Its flavor is so bright and strong, but if you want to taste it directly, you have to be prepared.

But today's Italians still drink robusta coffee, and they think Robsta is no worse than Arabica.

Development status:

The output of Robusta species accounts for 25% of coffee bean production, which accounts for 25% of coffee bean production. Its main producing country is Indonesia (one of its coffee beans is a kind of coffee bean processed by washing method, which 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, (West African countries with C ô te d'Ivoire, Nigeria and Angola as the center), and Vietnam has been more committed to coffee production in recent years. And include it in the national policy (Vietnam also produces a small number of Arabica coffee beans).

Wen was found to have strong resistance to leaf rust-the most widely used resistance.

The hybrid of Caturra and Timor. Was sent in Portugal in 1959.

Now. The palate is obvious and easy to distinguish, the bitter acid is a little astringent, and the aftertaste is often present.

Salty, low acidity and high bitterness in the Timo family

Influence, emit spicy herbs and fruit peel aromas. Planting density

With high degree and strong resistance to leaf rust, it has become a high-yield product.

Kind of. Oro Azteca is a dwarf selection.

In the past, Latin America was planted in large quantities on the advice of agricultural experts.

Catimor, after ten years, their advice has been proved to be wrong, because

Coffee farmers cannot sell the coffee beans they grow at the right price.
