About This Coffee:
Colombia loves to excite us with new and innovative processing methods like this unique nitro washed coffee. At Finca La Riviera, where the coffee processing for Finca Milan takes place, producer Julio Cesar Madrid Tisnes designed and perfected different fermentation protocols for a variety of methods, including washed, honey, natural, cold press, culturing, and nitrogen fermentations.
In the nitro washed process, ripe coffee cherries are subjected to embryonic stress so that the temperature of the cherries rises and falls to 12 degrees, keeping them in the best condition for further processing.
After pulping, the beans are placed in a bioreactor and inoculated with starter cultures (yeast and bacteria) and fruit must. The bioreactor is sealed and injected with nitrogen to facilitate the metabolic processes of the microorganisms. During this time, temperature, acidity, and Brix degrees are closely monitored against past data in order to time the end of the fermentation stage and initiate oxidation.
After leaving the bioreactor, the coffee beans are dried in solar dryers to 40% moisture then transferred to mechanical dryers until reaching 10% - 12% moisture. The resting period in the warehouse is around 45 days before the coffee is hulled and prepared for export.
*Our preferred brewing method for this coffee is Chemex with a 1:15 coffee to water ratio
