Lala Salama means ‘Sleep Well’ in Swahili, there couldn’t be a more fitting name to bestow upon our new regular feature of Sparkling Water Decaffeinated coffee from the African continent.This lot comes from our friends at Rwanda Trading Company, our sister company in Kigali, from decaffeinate coffee from the Gitega Hills Station.
Just 12km from neighbouring Bwenda in the Cyanika sector and slightly higher up, adjacent to a disused quartz quarry, sits Gitega Hills. Slightly larger than Bwenda, Gitega covers an area of around 6 hectares and is nearby the small town of Miko. Gitega is the name of the surrounding land cell. A cell being a smaller area within a larger sector, within a larger region or province. Established by RTC in 2016, the station has been managed since then by Alex. Everyone who works at Gitega is from the local community and Alex feels that the station plays a valuable and positive role in the area for the work it provides. Good rainfall the area experienced during the harvest pointed to great quality for the 2022 season’s yields. Gitega employs 150 people including 11 permanently, with the rest being seasonal workers. 90% are women. 1040 farmers contribute cherry to Gitega’s annual production and in 2016 they processed 400 tons of cherry. At the time of our visit they had aready hit 500 tons with the expectation to hit 700 before they stopped processing for the season. The farms all lie between 0.5km and 7km away and are serviced by 33 different cherry collection points. On average the contributing farms grow just 400 trees (1 hectare). Additionally, the station provides farmers with organic EM2 compost which consists of recycled cherry pulp from the station with some animal manure. All 1040 farmers using Gitega have completed or are current participants in the ATP.
THE SPARKLING WATER DECAFFEINATION PROCESS:
This process was first discovered by a scientist called Kurt Zosel at the Max Planck Institute for Coal Research in 1967 as he was looking at new ways of separating mixtures of substances. In 1988, a German decaffeination company called CR3 developed this process for decaffeination whereby natural carbon dioxide (which comes from prehistoric underground lakes) is combined with water to create ‘sub-critical’ conditions which creates a highly solvent substance for caffeine in coffee. It is a gentle, natural and organically certified process and the good caffeine selectivity of the carbon dioxide guarantees a high retention level of other coffee components which contribute to taste and aroma.
Sparkling water process : The green beans enter a ‘pre-treatment’ vessel where they are cleaned and moistened with water before being brought into contact with pressurised liquid carbon dioxide. When the green coffee beans absorb the water, they expand and the pores are opened resulting in the caffeine molecules becoming mobile.After the water has been added, the beans are then brought into contact with the pressurised liquid carbon dioxide which combines with the water to essentially form sparkling water. The carbon dioxide circulates through the beans and acts like a magnet, drawing out the mobile caffeine molecules.The sparkling water then enters an evaporator which precipitates the caffeine rich carbon dioxide out of the water. The now caffeine free water is pumped back into the vessel for a new cycle.
This cycle is repeated until the required residual caffeine level is reached. Once this has happened, the circulation of carbon dioxide is stopped and the green beans are discharged into a drier.The decaffeinated coffee is then gently dried until it reaches its original moisture content, after which it is ready for roasting. There are several benefits to using this process for decaffeination:
The agent used for extracting the caffeine is entirely natural and the process can be classified as ‘organic’ due to the complete lack of chemicals used throughout. There is also no health risk by consuming coffee that has been decaffeinated in this way.The way the process works means the other compounds in the green bean are left untouched, meaning decaffeination has no effect on the flavour and aroma of the finished product. The carbon dioxide is very selective and doesn’t extract the carbohydrates and proteins in the green bean which contribute to flavour and smell.The cell structure of the green bean and the finished roasted bean is unchanged which is of great advantage when working with speciality coffees. The by-products are 100% natural and recyclable.
