For those who like to drink coffee, they have heard of Manning for a long time, especially the well-known gold manning. When it comes to golden manning, they immediately think of Sumatra, because those who love it all know that Sumatra has the best aroma of gold manning.

But in fact, there is no specific variety of Mantenin coffee we drink, because there is no such variety, but Mantenin has a great reputation and has gradually become synonymous with the regional characteristics of Indonesian coffee. For exporters, you can get a good price by simply labeling mixed coffee as Manning. Why not?

After collecting the coffee cherries in the morning, in the afternoon, the coffee cherries will be peeled and pulped into wet beans with shells, which is what we call parchment coffee, and then put the shells into the sink to remove the floating defective beans.

Sumatra has a superior natural environment, and most of the water used will be mountain spring water.

The next step is to take out the dense beans and put them into a barrel for dry body fermentation, so that the pectose can be fully fermented to increase the flavor, usually between 12 and 36 hours, depending on the specific situation.

After exposure to the sun for 1-2 days, when the moisture is dried to 35-40%, the coffee beans are collected in woven bags, usually 40 kg and 80 kg each, and sent to the coffee processing plant for shelling.

The shelling process is to grind off the bean shell with a shell planer and then dry it until the moisture content reaches about 12% to 15%. The coffee beans are then sent for machine selection to remove a variety of impurities and then sorted by particle size.

The coffee after machine selection will be sent to the hand-selected warehouse for hand-selection, and the workers will pick out the defective beans one by one. It will be packed in gunny bags only after two or three hand selections.

Of course, accidents can happen.

In the shell planing process, the coffee bean temperature will rise to 30-60 degrees, and completely destroy the parchment, which is likely to trigger the bean sprouting.

Wet planing will also occur because the peel is removed in the production process, and the beans come into direct contact with the air, so defective beans such as mildew beans are much higher than water washing and sun drying.

This is the unique way of handling Sumatran Mantenin flavor.

In addition, the peel and pulp that have been removed can also be fermented into fertilizer, which can be added when applying for an organic coffee plantation if the plantation uses such ecological fertilizer.
