This bubbly drink, loved for its rich flavor and refreshing taste, can be made even more exciting when brewed at home using a ginger bug. In this guide, we will explore the enjoyable process of creating your own fermented root beer with this natural starter culture.
What is a Ginger Bug?
A ginger bug is a simple fermented culture made from ginger, sugar, and water. It serves as a natural starter for various homemade fermented beverages, giving them a distinctive flavor and a delightful fizz. For more on how to cultivate your ginger bug, you can check our detailed previous post.
Gathering Your Ingredients
To kick off your root beer brewing journey, you'll need the following ingredients:
1 gallon filtered water – Fresh and pure water is essential for optimal fermentation.
1 tablespoon of freshly grated ginger – This enhances the flavor profile and pairs well with your ginger bug.
1/2 cup dried sarsaparilla root – A traditional ingredient in root beer, sassafras adds unique flavor notes.
1/2 cup of birch bark – Adds flavour and anti-inflammatory effects.
1 cinnamon stick– This ingredient creates a warming experience to the beverage.
1 cup of sugar – Granulated sugar provides the necessary food for both the ginger bug and the yeast during fermentation.
1/2 cup molasses - Provides extra nutrients and a rich taste.
1 cup of ginger bug – This is your fermentation starter and the heart of the brewing process (See Recipe here).
Step-by-Step Brewing Process
Step 1: Prepare the Base Tea
Combine the water and herbs in a pot and bring to boil. Reduce the heat and simmer for 20 minutes. Remove the pot from the heat and let it return to room temperature.
Step 2: Strain
Strain the herbs and put the tea into a wide mouth gallon jar.
Step 3: Integrate the Ginger Bug
Stir in the sugar, molasses, and ginger bug. Cover the jug with a piece of cheesecloth secured with a rubber band.
Step 4: Fermentation Begins
Place your jar in a warm, dark spot between 70-80°F (21-27°C) for fermentation. Let it ferment for 3 to 5 days. Check it daily and give it a gentle stir to promote even fermentation. You may notice bubbles forming within 24 hours—a sign that your ginger bug is working!
Step 5: Bottling Your Root Beer
When your root beer has developed a slight fizz and a pleasant aroma, it’s time to bottle it! Using a funnel, pour the root beer into clean bottles, leaving an inch of space at the top. Be cautious not to overfill, as carbon dioxide may create pressure.
Seal the bottles tightly and leave them at room temperature for another 1 to 5-7 days to achieve the level of carbonation you like.
Step 6: Chill and Enjoy
After the second fermentation, place your bottles in the refrigerator to stop the fermentation process and chill them before serving. Once cooled, pop open a bottle, pour a glass, and enjoy the fruits of your labor.
Tips for Brewing Success
Taste as You Go: Everyone has different preferences. Feel free to adjust spices and sugar levels to suit your palate. If you prefer a sweeter root beer, consider using up to 1.5 cups of sugar.
Monitor Fermentation: If your mixture starts to overflow or smells sour, this may indicate over-fermentation. Daily checks will help you catch any issues early.
Experiment: The beauty of brewing is the chance to experiment. Try adding spices like cinnamon or nutmeg for a twist,.
