Processing of our coffee
Is the method converting the raw fruit of the coffee plant into the coffee. The cherry has the fruit or pulp removed leaving the seed or bean which is then dried. While all green coffee is processed, the method that is used varies and can have a signiﬁcant effect on the ﬂavor of roasted and brewed coffee.
A coffee plant usually starts to produce ﬂowers 3–4 years after it is planted, and it is from these ﬂowers that the fruits of the plant (commonly known as coffee cherries) appear, with the ﬁrst useful harvest possible around 5 years after planting. The cherries ripen around eight months after the emergence of the ﬂower, by changing color from green to red, and it is at this time that they should be harvested. In most coffee-growing countries.
2. Dry process
Dry process, also known as unwashed or natural coffee, is the oldest method of processing coffee. The entire cherry after harvest is ﬁrst cleaned and then placed in the sun to dry on tables or in thin layers on patios:
The harvested cherries are usually sorted and cleaned, to separate the unripe, overripe and damaged cherries and to remove dirt, soil, twigs and leaves. This can be done by winnowing, which is commonly done by hand, using a large sieve. Any unwanted cherries or other material not winnowed away can be picked out from the top of the sieve. The ripe cherries can also be separated by ﬂotation in washing channels close to the drying areas.
The coffee cherries are spread out in the sun, either on large concrete or brick patios or on matting raised to waist height on trestles. As the cherries dry, they are raked or turned by hand to ensure even drying and prevent mildew. It may take up to 4 weeks before the cherries are dried to the optimum moisture content, depending on the weather conditions. On larger plantations, machine-drying is sometimes used to speed up the process after the coffee has been pre-dried in the sun for a few days.
5. Cleaning and sorting
Sorting by Size and Density: Most ﬁne coffee goes through a battery of machines that sort the coffee by density of bean and by bean size, all the while removing sticks, rocks, nails, and miscellaneous debris that may have become mixed with the coffee during drying. First machines blow the beans into the air; those that fall into bins closest to the air source are heaviest and biggest; the lightest (and likely defective) beans plus chaff are blown in the farthest bin. Other machines shake the beans through a series of sieves, sorting them by size. Finally, a machine called a gravity separator shakes the sized beans on a tilted table, so that the heaviest, densest and best vibrate to one side of the pulsating table, and the lightest to the other
Process Cupping is one of the coffee tasting techniques used by cuppers to evaluate coffee aroma and the ﬂavor proﬁle of a coffee. To understand the minor differences between coffee growing regions, Indonesia Coffee to maintance our quality all green beans should be through this step before loading and shipment to our end customer. This step also very important things to space there is no chemical taste.
Grading is the process of categorizing coffee beans on the basis of various criteria such as size of the bean, where and at what altitude it was grown, how it was prepared and picked, and how good it tastes, or its cup quality. Coffees also may be graded by the number of imperfections (defective and broken beans, pebbles, sticks, etc.) per sample. For the ﬁnest coffees, origin of the beans (farm or estate, region, cooperative) is especially important. Growers of premium estate or cooperative coffees may impose a level of quality control that goes well beyond conventionally deﬁned grading criteria, because they want their coffee to command the higher price that goes with recognition and consistent quality
