Wilton Benitez Thermal Shock Caturra

"Wilton Benitez is the owner of an innovative coffee company in the Cauca region of Colombia called Granja El Paraiso-92. Both the company and Wilton are renowned for growing unique coffee varietals and for pioneering new methods of coffee processing in the region. After being handpicked at peak ripeness, the coffee cherries are sorted for quality by both size and density. They then undergo two rounds of sterilization, first with ozonated water, and second with ultraviolet light. The coffee cherries are in for a wild ride after this, as they're about to undergo three rounds of fermentation. The first round is 52 hours of anaerobic fermentation in cherry at a temperature of 18 degrees Celsius, during which time yeast is added to the mixture. While this initial round of fermentation is underway, the mucilage is recovered so that it can be added back to the fermentation environment in the next round. The cherries are then pulped before heading into round two: anaerobic fermentation in mucilage for 48 hours, at a slightly warmer temperature of 21 degrees Celsius. The cherries undergo a third and final round of fermentation in an aerobic environment for 68 hours. After this, they are washed using a thermal shock method: first, with water at 40 degrees Celsius, and second, with water at a chilly 12 degrees Celsius. Finally, the cherries are dried for 48 hours at a consistent temperature of 38 degrees centigrade."
