Simple Ways to Keep Your Kombucha Brew Warm
Warmth is essential to the kombucha process, and there are many simple ways to keep your kombucha brew warm. It will ensure that your brew stays healthy, producing acids that lower the pH to fend off mold. But it will also ensure that you're able to harvest your 'buch without waiting forever. The ideal brewing temperature for kombucha is between 70 and 80 degrees. Lower than that range, you are running the risk of allowing mold to form. Higher than that range, you might get finished 'buch more quickly but it will also potentially become vinegar more quickly.
It's best to find places in your home that are naturally producing or retaining heat. Beyond that, you can dress up your brew with heat mats, cooler-incubators and clothes to your heart's content. You could even build a box special for fermenting. Any combination of these methods will do wonders for your 'buch and keep you from pulling your hair out in these cool winter months. These are just a few suggestions and you are encouraged to branch out and think for yourself based on your home environment. If all else fails, just take it to bed. I won't judge you. Happy brewing!
