I added my ginger bug to my Ginger Brew. It's now been 5 days with no visible signs of carbonation. Should I Add more ginger bug to my Brew?
Assuming you bottled the bug + ginger sugar-water - It's best to wait. At least for 2 weeks, then re-evaluate.
Are the bottles warm ? More than 15C / 59F ? Ale yeast (and bread making yeast) will go dormant if it's too cold.
It could be there's only a small amount of yeast in each bottle, and it's taking time to establish itself. It may help to gently agitate the bottles to rouse the yeast.
