Sens Coffee - Castillo - Koji

Juan David Puerta is known for his distinctive co-fermentations. The KOJI-fermented Castillo is just one of his creations, but one of the few that doesn't belong to the category of "infusion" coffees. Since no direct fruit notes are added, but only microorganisms for fermentation, it is "only" a co-fermented coffee.

The spores of the Aspergillus oryzae fungus convert the starch contained in the coffee cherry into simple sugars. This dramatically intensifies the coffee's flavor nuances. Therefore, this coffee is not only a true natural coffee, but an absolutely flavorful powerhouse.

Juan David Puerta - a food engineer dedicated to coffee processing.

After completing his studies in food engineering, Juan David initially gained experience with various green coffee producers and exporters. However, instead of settling permanently into existing structures, he decided to use his expertise entrepreneurially. He rented space on a farm, selectively purchases fresh coffee cherries, and has since focused entirely on exceptional processing methods. These include osmotic dehydration with natural flavors and fermentation with koji mold – two processes that break new ground in sensory perception.

What makes Juan David particularly appealing is his open and honest approach. While some producers keep their methods secret or only selectively disclose information, he stands clearly by his processes – transparently, without marketing jargon. This attitude deserves support. That's why we're convinced: This koji coffee won't be the last one from him in our selection.
