6 Benefits of Fermented Coffee and How To Make It

Fermented coffee, also known as wine coffee, is a type of coffee created through a post-harvest fermentation process, which imparts a unique flavor similar to the aroma of wine.

Fermentation involves chemical reactions facilitated by microorganisms that help break down coffee compounds. This process enhances the coffee with beneficial enzymes, sugars, and other elements. Below are the health benefits of fermented coffee, comparable to those of coffee mixed with honey:

1. Aids Digestion
   The fermentation process converts indigestible substances into simpler molecules that are easier for the body to process. Fermented coffee is gentle on the stomach, making it suitable for those with digestive issues. It also introduces healthy bacteria and yeast, which improve gut health and aid in food absorption and digestion. These microorganisms are rich in prebiotics, boosting healthy gut bacteria and enhancing metabolism and digestion.
2. Suitable for IBS Patients
   Irritable Bowel Syndrome (IBS) can cause significant discomfort, including stomach pain, diarrhea, cramps, and constipation. Fermented coffee is beneficial for IBS sufferers, similar to the health benefits of decaffeinated coffee.
3. Enhanced Flavor
   Fermented coffee offers a richer, more complex flavor profile, often with a bittersweet, mildly fruity taste. The fermentation process breaks down complex starches and sugars into sweet alcohols, ethanol, and various acids, which contribute to the coffee’s sweet, malty taste.
4. Improved Aroma
   By controlling fermentation conditions, the taste and aroma of coffee can be significantly improved, reducing bitterness and enhancing overall quality. The breakdown of molecules during fermentation intensifies the coffee’s flavor and aroma, often resulting in a fruity, chocolatey scent without the bitterness of traditional coffee.
5. Prevents Teeth Staining
   Tannins, found in regular coffee, are responsible for its bitter taste and dark color, which can lead to yellowing of the teeth. During fermentation, tannins are reduced, which helps prevent staining and maintains a brighter smile.
6. Reduces Stress
   Fermented coffee contains about 30% less caffeine than regular coffee, making it a good option for those looking to lower their caffeine intake and manage stress levels.

How to Make Fermented Coffee

For those who enjoy coffee but need a milder brew, fermented coffee is an excellent choice. Here’s a step-by-step guide to making it:

1. Soaking
   Start by soaking coffee beans in water. This process allows the coffee to absorb water, creating a suitable environment for fermentation. After soaking, add a Symbiotic Colony of Bacteria and Yeast (SCOBY) to the mix, which introduces the necessary microorganisms for fermentation.
2. Inoculating
   Introduce yeast to the soaked beans by adding it to the fermentation medium. You can use a different microorganism or a previous batch of fermented coffee for this step. The beverage will be rich in bacteria and yeast after about a day, sufficient to begin the fermentation process.
3. Waiting
   Once inoculated, let the coffee beans ferment for 1 to 2 days. This waiting period is crucial as microorganisms break down complex sugars into simpler molecules like alcohol and acids. Monitor the temperature closely, maintaining an ideal environment of about 68°F (20°C) for 24-44 hours.
4. Cleaning and Drying
   After fermentation, it’s essential to dry the coffee beans to prevent mold and preserve flavor. Drying should be done evenly, using moderate heat to ensure consistency. This can be achieved through natural drying under the sun or mechanical drying using machinery.
5. Roasting
   Roasting the beans is the next step. This process extracts the coffee’s natural flavors and oils. Roasting should be done slowly with low heat to avoid burning the beans. The roast can range from light to dark, depending on your preference.
6. Grinding
   Finally, grind the roasted beans to the desired consistency. A manual grinder or an electric grinder can be used, depending on your brewing method. The grind size should match your preferred brewing technique, whether coarse for French press or fine for espresso.

This process yields a unique, flavorful coffee with numerous health benefits, making it a great addition to your daily routine.
