Co-fermented coffee

 Co-fermented coffee is a specialty coffee processed by adding external ingredients, such as fruits, herbs, or spices, to the coffee cherries during the fermentation stage to create distinct and vibrant flavor profiles. 

This natural process can result in intense fruit, spice, or even candy-like notes, but it is controversial within the industry for potentially masking the coffee's natural flavor and leading to disqualifications in competitions, according to some industry professionals. 

The Co-Fermentation Process

Mother Culture Creation: A "mother culture" is created with microorganisms from coffee plants and fed a mixture of fruit juices, fruits, and sweeteners. 

Cherry Preparation: Coffee cherries are selected based on their sugar content. 

Co-Fermentation: The cherries are pulped and then combined with the mother culture in a sealed tank for a controlled fermentation period. 

Drying: After co-fermentation, the cherries are dried, often in the sun and then under shade, until they reach a specific humidity level. 

Key Characteristics and Benefits

Flavor Innovation: The primary goal is to create unique and expressive flavor profiles, such as tropical fruit or candy-like notes, that are not achievable through traditional methods. 

Natural Flavor Development: Proponents argue that co-fermentation is an authentic way to develop flavor using natural ingredients and microbes, distinguishing it from coffees with added artificial flavors. 

Increased Market Value: Co-fermented coffees can command higher prices, as they offer a way to add value to coffee beans. 

Controversy and Industry Opinion

Natural vs. Artificial: Some argue that co-fermentation, even with natural ingredients, blurs the lines with flavored or infused coffee, which is often viewed negatively in the specialty coffee community. 

Disqualification from Competitions: The practice has led to disqualifications in high-profile competitions, such as the Best of Panama, with officials stating that co-fermented coffees are considered altered from their "natural DNA expression". 

Impact on Farmers: There's concern that co-fermentation could devalue the effort of farmers who invest in traditional processing methods, as it may become easier to achieve distinct flavors through this technique rather than through careful cultivation
