Using Tap Water for Kombucha
Can you use tap water when brewing kombucha? Yes, you can, but you do not want to use it straight out of the tap, not unless it’s filtered. If you plan on using tap water to brew kombucha, there are additional steps that are needed to make it suitable for use. This can be as simple as boiling the water or using a charcoal filter before use. We have a full post on this topic, which can be found here How to Brew Kombucha with Tap Water. Bottom line, If you want to brew kombucha with tap water, you will first need to remove the chlorine or chloramines.
Using Spring or Purified Drinking Water for Kombucha
Can you use spring water when brewing kombucha? Absolutely! This is a great option for brewing kombucha. What are the downsides? Well, it isn’t the most environmentally friendly option or most cost-effective. It also isn’t much fun lugging the jugs home. But for kombucha brewing purposes, we highly recommended it.
Using Filtered Water for Kombucha
Can you use filtered water when brewing kombucha? Yes! This is the best option, and luckily, water filters are relatively inexpensive. Also, they last quite a while, which is why this is the best and most practical option. What water filter system should you use? You want to look for charcoal filtration systems, which most are. The charcoal works to absorb impurities in the water and is effective in removing most of the chlorine and chloramines. The pitcher style filters, like the Brita Filter, use charcoal. I hooked up an under-the-sink filter in our kitchen, similar to this one that I LOVE. It has a separate faucet that comes up next to the main, so I have clean, filtered water on demand whenever I need it.
