The practice of American Coffee is introduced by Mount Jintamani, a coffee producing area in the United States.

Inety Plus thought that coffee itself is a kind of fruit, so he made his own exclusive treatment according to taste (W2), (H2), and (N2). When you understand traditional coffee processing, you will find that a small amount of adjustment can blur the distinction between them. For example, a little washing can be added at different stages of the densification process to achieve a lighter and brighter washing taste; controlling the degree of pulp fermentation can also make a sun closer to the effect of a dense treatment, or dense treatment can be more like a solarization.

According to the degree of effect of fruit flavor on taste, it can be divided into: W _ 2 ~ H _ 2 ~ 2 ~ 2. The distinction between these three flavors can also be simply understood as treatment methods: W2=WASH washing treatment, H2=Honey honey treatment, N2=NATURE sun treatment:

W2: lower (Low) fruit tonality; emphasizes brightness, acidity, and floral aroma.

H2: warm (Moderate) fruit tonality; emphasizes sweetness, fruit taste (rather than fruit flavor), and tea taste.

N2: higher (High) fruit tonality; emphasizes unrestrained, sweet and sour, jam and dried fruit flavors.

Solkiln: the so-called Solkiln method is a special treatment of 90 + company's patented technology. They dry the fresh coffee fruit in a house originally used to dry wood. In this house, special equipment is used to control the temperature and humidity needed to maintain the stability of the internal environment, while eliminating the impact of the local humid climate on the coffee.

Red: the so-called "red treatment" is a special treatment carried out by the 90 + team through their own patented drying technology, which makes the color of shelled coffee beans show varying degrees of red. This treatment will once again enhance the aromatic characteristics of the coffee itself, and the taste will reflect a strong sweetness with obvious fruit flavor.

Ruby: the so-called "ruby" treatment is also a more difficult and extreme way of dealing with red. So that the red treatment of sweetness and fruit to the extreme, accidentally over will become a bad fermentation taste of the extremely bad areas. This method also requires a lot of manual screening. Every raw bean must meet the "ruby" standard in order to be called a "ruby" bean. It has been eliminated and tried many times, and the last point is left to meet the standard of "ruby", so it is expensive.
