Anaerobic Coffee Guatemala — Oxygen-Free Fermentation
Guatemala Anaerobic Coffee
What is anaerobic coffee?
Anaerobic coffee is a post-harvest process in which coffee cherries are fermented inside sealed, oxygen-free tanks (hence the name anaerobic). This method, popularized in recent years, drastically intensifies the sensory profile of coffee, producing cups with intense sweetness, creamy body, and complex fruity notes reminiscent of wine, ferments, and exotic fruits.
