Quick Navigation
What is Coffee Kombucha?
Coffee kombucha is a fermented beverage made by combining brewed coffee with a kombucha SCOBY (Symbiotic Culture of Bacteria and Yeast) and sugar. The SCOBY consumes the sugar and caffeine, producing a slightly acidic, effervescent drink with a unique flavor profile that blends the earthy notes of coffee with the tangy taste of kombucha. It’s a fascinating fusion that offers a potential alternative to traditional coffee, with purported benefits like improved gut health and sustained energy.
The fermentation process also alters the caffeine content, typically reducing it compared to regular coffee. However, the exact amount can vary depending on factors like fermentation time, coffee strength, and the specific SCOBY used.
Pro Tip #1: Choosing the Right Coffee
Don’t just grab any coffee! Opt for a medium to dark roast with a balanced flavor profile. Avoid flavored coffees, as the added oils can negatively impact the SCOBY. A good quality Arabica bean often yields the best results.
Essential Materials and Ingredients
Before you begin your coffee kombucha brewing journey, gather the necessary supplies. Having everything on hand will ensure a smoother and more enjoyable process.
Key Information: Materials and Ingredients
- Coffee Beans: Approximately 1/2 cup of whole beans (medium to dark roast recommended).
- Sugar: 1 cup of granulated white sugar (avoid honey or artificial sweeteners for initial batches).
- Water: 1 gallon of filtered water, chlorine-free.
- Kombucha SCOBY: A healthy SCOBY with at least 1 cup of starter tea.
- Brewing Vessel: A glass jar with a wide mouth (at least 1 gallon capacity).
- Cloth Cover: Breathable cloth (cheesecloth, muslin) and a rubber band.
- Bottles: Several airtight bottles for secondary fermentation and storage.
Brewing Your First Batch: A Step-by-Step Guide
Follow these steps carefully to create your own delicious coffee kombucha:
- Brew the Coffee: Brew the coffee as you normally would, using your preferred method (drip, French press, etc.). Aim for a strong brew, using approximately 1/2 cup of coffee beans per gallon of water. Allow the coffee to cool to lukewarm (below 85°F/29°C) before proceeding. Caution: Hot coffee can damage or kill the SCOBY.
- Dissolve the Sugar: While the coffee is cooling, dissolve 1 cup of sugar in the cooled coffee. Stir until completely dissolved.
- Combine and Add SCOBY: Pour the sweetened coffee into your clean glass brewing vessel. Add the SCOBY and 1 cup of starter tea (unflavored kombucha from a previous batch).
- Cover and Ferment: Cover the mouth of the jar with the breathable cloth and secure it with a rubber band. This prevents fruit flies and other contaminants from entering while allowing air to circulate.
- Ferment in a Dark, Room-Temperature Place: Place the jar in a dark, room-temperature (68-78°F/20-26°C) location. Avoid direct sunlight.
- Taste Test and Bottle: After 7-30 days (depending on temperature and desired tartness), begin tasting the kombucha. Use a clean straw or spoon to avoid contaminating the brew. Once it reaches your desired tartness, it’s ready for bottling.
- Secondary Fermentation (Optional): Pour the kombucha into airtight bottles, leaving about an inch of headspace. At this stage, you can add flavorings like fruit juice, ginger, or spices. Seal the bottles tightly and allow them to ferment at room temperature for 1-3 days to build carbonation. Caution: Burp the bottles daily to release excess pressure and prevent explosions.
- Refrigerate and Enjoy: Once carbonated to your liking, refrigerate the bottles to slow down fermentation and prevent further pressure build-up. Enjoy your homemade coffee kombucha!
Pro Tip #2: Maintaining a Healthy SCOBY
Your SCOBY is a living organism! Always handle it with clean hands and utensils. When bottling your kombucha, reserve at least 1 cup of starter tea to use in your next batch. This ensures a healthy and active culture.
Troubleshooting Common Issues
Even with the best intentions, brewing coffee kombucha can sometimes present challenges. Here’s how to address some common issues:
Troubleshooting Tips
- Mold: If you see fuzzy or colorful mold on your SCOBY, discard the entire batch and start over with a new SCOBY.
- Slow Fermentation: Low temperature or a weak SCOBY can slow down fermentation. Ensure the temperature is within the optimal range and consider using a stronger starter tea.
- Overly Acidic Kombucha: Over-fermentation can result in kombucha that is too sour. Reduce the fermentation time in future batches.
- Lack of Carbonation: Insufficient sugar during secondary fermentation or leaky bottles can prevent carbonation. Ensure bottles are tightly sealed and add a small amount of sugar (1/2 teaspoon per bottle) during secondary fermentation.
Pro Tip #3: Measuring Acidity
Invest in pH strips to monitor the acidity of your kombucha. A pH between 2.5 and 3.5 indicates a safe and properly fermented brew.
Coffee Kombucha Flavor Profiles: A Comparison
| Feature/Item Name | Pros | Cons | Key Features |
|---|---|---|---|
| Light Roast Coffee Kombucha | Brighter, fruitier flavor; higher caffeine content (potentially). | Can be more acidic; may require longer fermentation time. | Floral aromas, citrusy notes. |
| Medium Roast Coffee Kombucha | Balanced flavor; good caffeine level; versatile. | May lack the complexity of light or dark roasts. | Nutty, caramel notes. |
| Dark Roast Coffee Kombucha | Bold, rich flavor; lower caffeine content; smoother finish. | Can be bitter if over-fermented; may overpower other flavors. | Chocolate, smoky notes. |
| Cold Brew Coffee Kombucha | Smoother, less acidic flavor; naturally sweet. | Requires a longer brewing time for the initial coffee. | Less bitter, more mellow. |
Pro Tip #4: Experiment with Flavors
Don’t be afraid to get creative! Add spices like cinnamon, cardamom, or vanilla bean during secondary fermentation to enhance the flavor of your coffee kombucha. Fruit juices like orange or berry can also add a delightful twist.
Frequently Asked Questions
Yes, you can use decaf coffee. However, keep in mind that the caffeine in regular coffee provides some nutrients for the SCOBY. Decaf coffee kombucha may ferment slower and require a slightly longer fermentation time.
The caffeine content varies depending on the strength of the coffee, fermentation time, and the activity of the SCOBY. Generally, it’s significantly lower than a regular cup of coffee, but it’s best to start with small amounts to gauge your tolerance.
Coffee kombucha, like regular kombucha, contains probiotics, antioxidants, and enzymes that may offer health benefits. However, it’s important to consume it in moderation and be mindful of the caffeine and sugar content. As with any fermented food or beverage, individual responses may vary.
Yes, it’s normal for the SCOBY to sink. A healthy SCOBY will produce a new, thin layer on the surface of the kombucha. The old SCOBY can sink or float, and both are perfectly fine.
