Why It Works
- Straining the fruit-and-herb puree removes undesirable fiber and seeds, for a cleaner, smoother closing beverage.
- Including fruit (plus a small quantity of extra sugar) for the secondary fermentation offers loads of meals for the yeast to transform into CO2, for refreshingly fizzy outcomes.
One of many nice joys of brewing your personal kombucha is its versatility: So long as you’ve a dependable, primary kombucha recipe, you can also make just about any taste you need. This recipe builds on my primary jasmine tea kombucha,* with some enjoyable adjustments throughout the secondary fermentation (what kombucha adepts consult with in shorthand as “F2”) to create a refreshing blackberry-mint taste. Jasmine tea works properly as a light, floral taste base with comparatively few bitter or tannic notes—a clear canvas for flavors and infusions.
* That recipe additionally presents a complete evaluation of the complete kombucha-making course of, and is value a learn in case you’re new to kombucha brewing.
Including fruit or natural infusions is a standard observe when bottling kombucha. Whereas these substances primarily taste the brew, the pure sugars in fruit present further gas for yeast to provide much more carbon dioxide—the important thing to the fizzy high quality we affiliate with kombucha. Recent plant materials, whether or not fruit, herbs, and even greens, additionally serves as an added supply of untamed yeasts, which will help speed up fermentation. Recent fruit will be added in chunks or as a puree or juice throughout bottling.
On this recipe, I add a purée of blackberries and mint within the second fermentation—robust however complementary flavors that end in a refreshing, fragrant, and deeply crimson pink kombucha. Puréeing the combination will increase the floor space of the infusion, leading to a extra intense taste whereas requiring much less fruit. I additionally add a small quantity of sugar to the purée, which ensures there may be loads of sucrose accessible for the second fermentation.
One widespread downside when utilizing fruit purées in kombucha is the quantity of sediment and pulp they introduce to the beverage; even seeds can find yourself within the completed drink. Whereas pulp and seeds don’t adversely have an effect on the standard of fermentation, they’ll make the kombucha cloudy, fibrous, and in any other case “chunky” quite than clear and easy. To mitigate the pulp on this recipe, I pressure the puree by way of a number of layers of cheesecloth earlier than bottling.
Since there may be a lot added sugar and plenty of potential sources of untamed yeast, the second fermentation happens shortly on this recipe—in as little as two days when fermenting at hotter temperatures (round 80℉). The ensuing kombucha options massive, frothy bubbles and boasts loads of tart, faintly bitter blackberry taste that performs superbly with the cooling aroma of mint.

Seal bottles and retailer in a darkish space between 70 and 80°F (21-27°C) till beverage reaches desired degree of carbonation, 3 days to 2 weeks. Examine one bottle periodically to observe carbonation: it’s prepared while you see small bubbles rising pretty quickly to the highest, even when capped; if utilizing twist caps, the cap will pop up barely when a superb degree of carbonation is reaches; if utilizing flip-top bottles, you could have to open one bottle to verify the carbonation, resealing if there is not sufficient fizz. When kombucha has reached desired degree of carbonation, transfer bottles to fridge and retailer for as much as 8 weeks.

Particular Tools
Massive fine-mesh strainer, one-gallon glass jar, funnel, massive espresso filters, 5 16-ounce (1-pint) twist-cap bottles or flip-top bottles; dishwasher or a sanitizer like Star San (for cleansing vessels); pH meter or pH strips
Notes
Starter tea can both be from a previous batch (most popular) or from a bottle of store-bought kombucha. Use an unflavored jasmine or inexperienced tea kombucha if doable. For finest outcomes, use jasmine or inexperienced tea kombucha from a earlier batch.
One of the best supply of a SCOBY is a buddy or acquaintance who often brews kombucha. You can even purchase them commercially, however notice that SCOBY’s which are offered dry or unsubmerged in starter liquid are inclined to carry out weakly compared to these offered recent and packaged in starter tea
Make Forward and Storage
The completed bottled kombucha will be refrigerated for as much as 8 weeks.
