The longer fermentation time for yeast processed coffees, like this Oro Natural coffee, allows for more developed flavors.

ABOUT THIS COFFEE

Biloya washing station is located at 1,720 meters above sea level in Kochere, in Yirgacheffe. Over 300 farmers deliver cherry grown in the surrounding area. The distinct wet and dry seasons create prime conditions for coffee processing.

CULTIVATION

Farming methods in the region remain largely traditional. Yirgacheffe farmers typically intercrop their coffee plants with other food crops. This method is common among smallholders because it maximizes land use and provides food for their families.

In addition to remaining traditionally intercropped, most farms are also organic-by-default. Farmers in Yirgacheffe typically use very few — if any — fertilizers or pesticides. Most farm work is done manually by the immediate family.

To capitalize on the magnificent climate, that station provides training to help farmers produce better quality cherry. Training focuses on procedures for harvesting and transporting cherry.

HARVEST & POST-HARVEST

After sorting, cherry is placed in airtight bags and Oro yeast purchased from the French company Lalcafe is added. The bags are then sealed covered and left to ferment in this environment for approximately 36 hours.  

LALCAFÉ ORO™ yeast (Saccharomyces cerevisiae) was specially developed for coffee production over a four-year period of research and trials. Trials in various regions and environments showed that Oro is well suited to better control the wet process’ efficiency and to upgrade the cup quality. Oro’s ability to flourish even at low temperatures means it is equally suited for use across most altitudes. The yeast is able to control the fermentation process against the risk of spoilage micro-organisms that can generate undesirable defects. Furthermore, its specific metabolism and its high capacity of implantation even at cold temperatures (minimum 15°C inside the coffee tank) allows for the expression of fresh and fruity characteristics of the coffee beans while respecting the varietal original aromas of the beans. 

The longer fermentation time for yeast processed coffees also allows for more developed flavors. The extra time enables the beans to absorb metabolites, which can enhance flavors. Complexity, acidity, brightness, floral and high notes, and more are all boosted by the lengthened fermentation time.
