I made some DIY Ginger Ale Ejuice just over 2 weeks ago on the 17th Feb 2019 and have been vaping it for a few days so it's fully steeped in 2 weeks!
As you probably already know that ginger is very good for cleaning the lungs and the Chinese have been using this for over 2000 years, they digest it by making tea with the actual root from the ginger, I've been vaping it without any ill effects!
The Ginger i bought is from Lubrisol and it seems to be a natural flavour, the recipe below makes 100ML and is 3% nicotine.
The taste is exactly like ginger ale on the inhale and exhale and leaves your mouth feeling fresh, in fact I'd say it's even better than drinking the ginger ale soda!
I have also made another one with menthol in I'll post that tomorrow!
Caution: Let it steep a couple of weeks, any time before that and you'll be sneezing lol
