The coffee beans have now started the germination process and activate various enzymes like metabolize polysaccharides – that is, natural sugars start to break down. Several researchers have found out that the more the enzymes are washed on the processing of natural instincts, the more they become free of sugar and other compounds that are transformed into aroma-producing compounds. All these factors combine to make and add more the increasing acidity of the coffee.


Natural coffee is sweeter when washed, this is because of the fermentation of sugars in the pulp. Both the washed and natural coffees experience fermentation. However, there is a difference and uses a lesser number of washed coffees. During fermentation, microbes modify proteins, carbohydrates, and Chlorogenic acids. More precursors to aromatic compounds are created in the natural coffees, this in return leads to the fruity, floral, and adds more of a caramel tone to the final cup.

So at this point, the roaster needs to know the amount, temperature and time of roasting for which these should be roasted especially during the initial stages.

Washing method

This is also one of the most common coffee roasting methods in the coffee industry, the processing method produces a clean cup and usually calls for the honey method. But this is just a resemblance to the honey method as water is used to make the coffee beans sticky.
