Bring some color and vitality to your winter days with cranberry kombucha — a fizzy, tart, and refreshing drink full of vitamin C, antioxidants, and gut-friendly probiotics. This cranberry-orange version is perfect when fresh cranberries are in season, but it’s delicious any time of year.

Why Cranberry and Orange?

Cranberries have a naturally tart flavor that pairs beautifully with the sweetness and zest of oranges. The result is a tangy, refreshing kombucha that’s as delicious as it is good for you.

Besides their taste, cranberries are known for their immune-supportive and urinary-tract-protective benefits, while oranges add vitamin C and a touch of brightness to this probiotic powerhouse.

The Second Fermentation Explained

The second fermentation is where kombucha gets its flavor and fizz. After the initial ferment with your SCOBY (Symbiotic Culture of Bacteria and Yeast), this step introduces fruit or herbs — in this case, a cranberry-orange syrup — to develop natural carbonation.

Don’t worry about the sugar in the syrup; it’s the food source for the beneficial yeasts and bacteria that create the bubbles.

Cranberry Kombucha Recipe

This recipe yields about four 16–18 oz bottles of perfectly fizzy kombucha.

Ingredients

For the Cranberry Syrup

• 2 cups fresh or frozen cranberries
• 1 cup water
• 1 cup organic cane sugar (reduce to ¾ cup for a less sweet flavor)
• Juice and peel of one fresh orange

For the Second Ferment

• 7 cups brewed kombucha (from black or green tea)

Instructions

1. Make the Cranberry Syrup

1. Combine cranberries, water, sugar, orange juice, and peel in a pot.
2. Bring to a simmer, stir occasionally, then cover and cook on low for 5–7 minutes.
3. Remove from heat, mash the cranberries gently, and let sit (covered) for 15 minutes.
4. Strain through a fine-mesh sieve or cheesecloth, pressing to extract all liquid.
5. You should have about 2 cups of rich cranberry syrup.

(Tip: Save the leftover pulp to blend into a quick, pectin-rich cranberry jam!)

2. Second Fermentation

1. Pour the 7 cups of brewed kombucha into a large pitcher.
2. Add the cranberry syrup and mix well.
3. Using a funnel, pour the mixture into flip-top bottles, leaving 1–2 inches of headspace.
4. Seal tightly and let the bottles sit at room temperature for 2–3 days, away from direct sunlight.
5. “Burp” bottles daily (open briefly) to release excess pressure and prevent overflow.
6. When the kombucha is bubbly and slightly tangy, refrigerate to stop fermentation.

How to Serve

Serve over ice with a few fresh cranberries or an orange slice for garnish. It’s a festive, digestive-friendly drink after big meals or holiday desserts — and an excellent alternative to soda or wine.

Stored in the fridge, the kombucha will keep for up to a month.

Bonus Tip

If you’re feeling creative, try adding a touch of ginger, cinnamon, or clove to the cranberry syrup for a cozy, spiced winter version.
