Qianjie-Sumatran Coffee and Java Coffee

Sumatran caffeine is famous for its unique aroma of herbs and trees. This is partly due to the mix of planting varieties and the local climate. On the other hand, it is due to a special processing method, called wet shell method, locally known as Giling Basah, which gives these coffees many unique qualities.

Before the 1970s, coffee in Sumatra was processed in two of the most common methods in the world: washing and tanning. In the 1970s, Japanese interest in Sumatran coffee led to the introduction of wet shell technology. This is a unique treatment and drying method, which is to a large extent the reason for the unique flavor characteristics of Sumatran coffee and the bluish blue color of its coffee.

Java may have the most complex history of so many coffee varieties, if not rosy summer.

Although it is called Java, it is by no means an Indonesian bean. Java originated in Ethiopia. As early as the 19th century, the Dutch introduced this bean from Ethiopia to Java, Indonesia, hence the name Java. In the middle of the 20th century, the French company Vilmorin collected seeds from Prutes (Prut), a famous grower in Java, Indonesia, and sent them to Cameroon in Africa.

Another breeder in Cameroon, Pierre Bouharmont (Pierre Buhamont), found that Java is partially resistant to coffee berry disease, a coffee disease that afflicts Africa, and yields are good without much fertilizer. After 20 years of optimal selection, Cameroon released the bean seed for farmers in 1980-90.

After genetic fingerprinting of the molecular markers, the research institute has been able to conclude that Java is an endemic species from the Ethiopian native variety Abysinia. If planted at high altitude, Java will have excellent quality and can even compete with Rose Summer!

In 1991, breeder Benoit Bertrand (Benoit Bertrand) sent Java bean seeds to Costa Rica through the International Center for Agronomic Research (CIRAD) to provide to small coffee farmers. The aim is to give small coffee farmers access to new varieties that are less fertilized and resistant to berry disease, even though there was no serious berry disease in Central America at the time.

Based on this consideration, the seeds were sent to all countries where coffee cultivation technology development and modernization regional cooperation projects (PROMECAFE) mutual aid alliance, but never really promote cultivation in those countries, no country has ever released this variety to the outside world. Subsequently, Java's quality potential at high altitudes was recognized. In 2016, Panama in Central America became the first coffee country to recognize Java.

Panama believes that the Java variety is an attractive substitute for Rosa, which has high flavor quality, good tolerance to leaf rust and coffee berry disease, and is very suitable for small farmers with low input.

Knowledge: in the 1860s and 1970s, outbreaks of coffee leaf rust destroyed the Indonesian coffee market and caused the Dutch to abandon many estates. With the collapse of the plantation, workers occupied small plots of land and eventually replanted coffee with Robosta coffee and various disease-resistant Arabica hybrids.

In short: Qianjie is a coffee research hall, happy to share the knowledge about coffee with you, we share unreservedly just to make more friends fall in love with coffee, and there will be three low-discount coffee activities every month. The reason is that Qianjie wants to make more friends drink the best coffee at the lowest price, which has been Qianjie's tenet for 6 years!
