Gold Series - Colombia Nitro Fermentation

Our Gold Series of coffees feature premium, limited-edition offerings that represent the truly special side of coffee. We purchase small amounts of ones that we find unique and interesting, and we roast them until they're sold out. Once they're gone, they're gone.

What is nitro fermentation? After the coffee is picked and depulped, the beans are placed in a tank, introduced to fruit and starter cultures (like yeast and bacteria), and infused with nitrogen. The idea is that, in an oxygen-free environment, microbial activity can be precisely controlled, and the result is coffees that are vibrant with prominent fruit character.

We gets lots of candy-like fruity notes in this one: blueberry, watermelon and lemon-lime. It comes from Julio Cesar Madrid Tisnes, a third-generation coffee grower who has designed and perfected different fermentation protocols for a variety of methods, including nitrogen fermentations. Tisnes' Finca Milan sits in the central foothills of the Andes Mountains, and the microclimate there (which reaches up to 86 degrees fahrenheit in the daytime and can drop to the 50s in the evening) allows coffee cherries to develop complex and unique flavors.
