Fermented foods and drinks are so good for digestion. I love to make fermented juice. It’s similar to Kombuca but much easier to make. The “ginger bug” does all the work. Here is a link that I used to help me: https://zerowastechef.com/2015/06/10/ginger-bug/
I learned the hard way that organic ginger, organic sugar and bottled water are the only way to go. Once you’ve started your “bug” it’s very easy to maintain.
The drink is SO GOOD! It’s a bubbly tasty concoction.
