Looking for a refreshing summertime kombucha recipe? Be sure try this! Juicy, ripe watermelon pairs with fresh squeezed lime and fresh mint to create a flavor trifecta that you can’t resist.
Watermelon reaches its peak sweetness during the height of summer, right when you need it most. It’s hot outside and it’s the simple things that bring the most joy—like a perfectly cold piece of fresh watermelon.
This recipe is great for any leftover watermelon you have but is also worth the effort to take a trip to the store to grab some.
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.
