This coffee is exclusive, it is another level. The ripening of the fruit is complete in the plant, that is why it does not give the sensation of acidity in the stomach, normally the acidity is due to the presence of some green beans.
Ok so the berries being picked at the right time is a major key. I realize with a lot of the coffees, especially instant, they have a lot of acidity, maybe they add preservatives as well.
Yeah, it has a lot to do with the selection of the beans, including the height of sowing. You are right, preservatives are added to instant coffee and that lowers the quality and can produce acidity.
