Blueberry Vanilla Kombucha Recipe

Name: Blueberry Vanilla Kombucha Recipe
Prep time: 10 min
Ingredients: 16 Oz Kombucha from a completed primary fermentation.; 1/4-1/2 tsp Vanilla Extract; 1/4 cup Fresh or Frozen Blueberries (thaw first if using frozen); 16 Oz Swing Top Bottles; Funnel; Measuring Spoons; Blender

Delicately Sweet and Deliciously Tart, Blueberry Vanilla is an Uncommon but Beautiful Combination for Kombucha Brewing.

Like the surprisingly delicious sample you received as a kid at the ice cream store, this Blueberry Vanilla Kombucha Recipe is reminiscent of a tasty fruity dessert with each sip, while at the same time refreshing. Imagine that scoop of blueberry ice cream with the blueberry chunks and swirls throughout that was only made better by the creamy vanilla goodness it was mixed with – now mix it with Kombucha and bottle it! We’ve taken the guesswork out and got the perfect measurements of blueberries and vanilla extract for you to make this tasty concoction at home.

PRIMARY VS SECONDARY FERMENTATION

It’s important to note that brewing homemade kombucha is almost always a two-step fermentation process. Brewing kombucha is only a one-step process for those who prefer an unflavored flat kombucha. Otherwise, the steps consist of a primary fermentation and secondary fermentation.

Primary Fermentation: The primary fermentation is the first step of the kombucha brewing process. This is where your SCOBY transforms regular sweet tea into the tart and slightly sweet kombucha we love. At the end of this stage, you will have finished kombucha, but it will be flat and unflavored. Have you skipped this step? Then check out our guide on making kombucha at home or our guide on making jun kombucha at home. Traditional kombucha is going to yield a bolder brew, while jun kombucha is milder and a bit more tart.
Secondary Fermentation: The secondary fermentation is the step where you bottle, carbonate, and flavor your kombucha by the addition of sugar and flavors. This step is essentially adding a bit of sugar/flavor to each airtight bottle and letting it ferment a little longer, allowing the yeast to carbonate the beverage in an airtight environment naturally. How exactly does this happen? See our post on kombucha secondary fermentation here.

Since this recipe is for the secondary fermentation, to make this recipe, you’ll need to have kombucha that has finished the primary fermentation and ready to bottle.

INGREDIENTS

Kombucha: You need kombucha that has completed primary fermentation and is ready to bottle and flavor.
Blueberries: You can use fresh or frozen blueberries. You’ll want about 1/4 cup per 16 fl oz bottle of kombucha.
Vanilla Extract: This is what gives that extra layer of smooth sweetness to the drink. A high-quality vanilla extract yields a fresher end product but feel free to use what you have on hand to experiment.

SECONDARY FERMENTATION PREPARATION

This recipe makes one 16-fluid-ounce bottle. A 1-gallon batch of kombucha will make seven 16-ounce bottles, so for one gallon, you will need to multiply the ingredients by 7. Before beginning this recipe, you will need to:

Reserve 12 – 16 fluid ounces of kombucha and a pellicle from a batch of kombucha that has finished primary fermentation. It’s best to pour from the top of the brew jar as the bottom will have a much higher yeast concentration. Use this as the starter for your next gallon batch of kombucha. If you need to make kombucha to get caught up to this step, you will need to see our post on how to make kombucha.
With your kombucha starter tea and SCOBY placed aside, enough kombucha will be left over in the jar to make seven 16 oz bottles when pulled from a gallon batch. Flip-top or swing bottles are the gold standard and are considered the best bottles for kombucha secondary fermentation. However, any bottle with a lid designed to hold pressure will work. It’s important to note the difference between airtight and pressure-rated lids. Airtight lids alone are not good enough for secondary fermentation; in addition to being airtight, the lids must also be capable of holding pressure. Airtight lids are designed to keep ambient air from entering and exiting; however, they are not designed to hold pressure. Inadequate lids will allow carbonation to leak during secondary fermentation, thus preventing your kombucha from ever carbonating.
