What is the relationship between Panama rose summer and flower queen? What is the difference between Arabica's tin card and bourbon?

Just as there are unique varieties such as green apples and snake fruits in apples, coffee also has a variety of different varieties. It is not only the difference in appearance, but also an important factor affecting the taste of coffee, so when we buy coffee beans, variety is also an important concern.

Before Qianjie, there was an issue on the identification of the appearance of common varieties, in order to let everyone see the appearance differences between varieties and varieties from an intuitive point of view. Of course, in real life, this method does not apply, after all, there are hundreds of coffee varieties, countless people have the same appearance, we can not directly judge the variety of coffee beans from the appearance (most). However, it is necessary to get to know each other. And what Qianjie wants to share today is the introduction of some common coffee varieties on the market, in order to deepen people's understanding of them.

Many of the varieties we have recognized so far have evolved from two varieties under the Arabica category. And the iron pickup is one of these two veteran varieties. It is not only the first coffee variety that came out of Ethiopia and spread all over the world (and then spread to the world through Yemen), but also the spokesman of Arabica. The "Arabica image" we can see on the Internet is almost always a long, round tin pickup. The well-known Blue Mountain Coffee uses a variety of iron pickup.

Bourbon / Red bourbon is another veteran species, which spread to the world a little later than the tin card. It is important to know that bourbon is a natural variant of the iron pickup, which is oval because of its length, while the bourbon is short at both ends and chubby and round as a whole. When the two are placed together, it is easy to distinguish between them.

It is worth mentioning that due to the subsequent emergence of yellow bourbon (a hybrid between bourbon and yellow bourbon), bourbon has a nickname "red bourbon" in order to distinguish it from yellow bourbon.

Whether it is bourbon or tin pickup, although they have excellent coffee taste, they have little resistance to disease. Therefore, it is easy to fall down one after another because of the erosion of the disease, coupled with the high difficulty of planting and low yield, so many of the producing areas where they were originally planted have experienced leaf rust and have been replanted into other varieties with high disease resistance and high yield.

In the year of SL28 and SL341930, the British set up the Scott Agricultural Laboratory in Kenya to cultivate new varieties with strong disease resistance to replace the old ones, and then began more than a decade of research and breeding. Finally, the SL series of beans with high disease resistance was born! Among them, the most outstanding bean varieties are SL28 and SL34. "SL" is the abbreviation of Scott Lab, and 28 and 34 are the serial numbers of the variety.

At first, it was thought that they were all varieties of bourbon, because most of the provenances in the laboratory came from Bourbon Island, where the family got rich. However, after WCR testing in recent years, it is found that SL34 is not the case, it is a variety of iron pickup. That's why there is such a big difference between the appearance of SL28 and SL34, one is round, the other is long, which is very reasonable.

Kaddura and Kadu Ekadura are natural varieties of bourbon. At the beginning of the 20th century, a small bourbon plant was found in a bourbon plantation in the Brazilian state of Minas Gerais. After testing, it was found that it was caused by gene mutation. As a result, this bourbon variety was named "Caturra", meaning "small". Kaddura has higher production capacity than bourbon and is more adaptable, so it will not be too demanding on the planting environment.

Kaduai is a hybrid of Kaddura and New World, which is a natural hybrid of Bourbon and Tieka, which was originally named "Hmur2077". Kaduai has high production capacity, strong disease resistance and suitable flavor, at the same time, it also inherits the petite appearance of Kaddura and the attribute of "hard life". So it can be seen that this variety is still very excellent, so its name has been changed from "Hume 2077" to "Catuai", which means "very good".

Rose summer "Geisha" must have been known to everyone can no longer be familiar with, although there are many kinds of rose summer on the market (such as Gory Rose Summer and Rose Summer 1931), but nothing impresses us most than the "T2722" player who made his fortune in Panama.

Rosa was discovered in 1931 in the Kafa Forest of Ethiopia, but in the era of re-roasting coffee, Rosa had no stage to play its part. Until it finally came to the era of boutique coffee with emphasis on flavor after more than 70 years of drifting, Rosa rose became famous in Panama with its outstanding flower flavor and fruit rhyme. Interestingly, because Rosa entered the wrong name when it was collected that year. What should have been included was Gesha, but as a result, an I was added and became Geisha. Geisha happens to be the English word for "geisha" (a professional name in Japan), so Taiwan uses the literal translation of "geisha" to call Rose Xia. As a result, an Ethiopian native species of the 17-year-old fire was named "Sakuran" when it was introduced to China, implying that it is a bean seed that can surpass the rose summer, because Sakuran is the top existence of a geisha.
