FAQ – Co-fermented Coffee
What is co-fermented coffee?
A co-fermented coffee is a coffee whose fermentation is carried out in the presence of natural ingredients (fruits, pulps, selected yeasts, spices or other substrates), intentionally added during the post-harvest process in order to influence the final aromatic profile.
This is not a coffee that is flavored after roasting.
Is co-fermented coffee natural?
Yes, when it's done well.
At 94 Celsius, we only work with co-fermented coffees at the producer level , with natural, traceable ingredients integrated during fermentation , never after.
Why does co-fermented coffee taste so intense?
Because fermentation acts as an aromatic amplifier .
Yeasts and microorganisms transform the sugars in the fruit and interact with the compounds in the coffee, creating ultra-expressive profiles:
- tropical fruits
- strawberry, candy, red berries
- explosive florals
- creamy and long finishes
Why is 94 Celsius considered a pioneer in Montreal?
Because we were already working with co-fermented coffees before it was fashionable , in collaboration with innovative producers and serious protocols.
In Montreal, no roaster was exploring this type of coffee with such transparency, consistency, and rigor at the time.
Is co-fermented coffee more acidic?
Often more vibrant , yes, but not aggressive.
Well-controlled fermentation brings a juicy, fruity and structured acidity, rather than a raw or unbalanced acidity.
Who is co-fermented coffee intended for?
- For curious coffee lovers
- For fans of fruity and funky profiles
- For those who want to experience an extraordinary taste sensation
