Four years ago we started an investigation project about Anaerobic Fermentation. El Diamante (The Diamond) is the first result of this investigation. The Anaerobic Fermentation Process consists on taking the coffee beans right after the pulping stage and putting them into the fermentation tank. Then mucilage, previously chosen, is added. We mix the beans, the mucilage and a little bit of water putting a hermetically sealed lid on and monitoring all the process from beginning to end. We must take care of different factors such as: Temperature, PH, time, pressure and brix degrees.

The main purposes of this process is to potentiate or increase the flavors present in the mucilage and make an exchange between the mucilage and the beans, this is how we end up having a completely different coffee.
