I have made beer, I drank it all lol. I have had a ginger bug going for almost 2 years. I make fermented lemonade and drink it couple times a week. It’s delicious. I haven’t had heartburn in 2 years either. I used to make sourdough, but I started eating keto about a year, and 70lb, ago and that means no bread. I use sugar to make my ginger bug but I let my lemonade go untilmost of the sugar is gone and I sweeten with stevia. One time it got boozy and I got buzzed! Lemonade is super simple too. To make the bug just grind up ginger and stick it in a sterile jar with a pinch of brown sugar and distilled water. I only harp on sterile jars and distilled water because the Former keeps you safe and the later keeps the yeast and bacteria you want safe. Well rubberband a coffee filter on the jar and let it sit on top of your fridge for a day. After that pour a little water out, and add enough to refill, adding another punch of ginger and brown sugar. Lossy put the cap on and set on your freezer. Repeat this process for a few days and you will see bubbles. Congratulations you new have an active culture. You can keep it in the fridge and feed it once a week and it will live forever.
To make thenlemonade chop up a few lemons, and either rough chop some ginger and add it in, or make some jinjer tree, and add it in once cool if you like it spicy, I do. Add about half the liquid from a jar of bug, and top off with distilled water, and a cup of white sugar half a cup if it’s a quart jar. Cover and let it go. Bur0 it daily or your jar will pop. You can drink it any time. Earlier will be more sweet. Later will be more sour. If it’s warm it can get boozy, but it will never be so boozy to get you hammered, like 3% max.
