Concentrates with alcohol?!

Does anyone im sure you know but whats with
These double labels on my bottles and do most companies add alcohol to these concentrates? Cuz I dont remember
There being alcohol in them?


If it has alcohol in it then it most likely was the flavor extract agent used to extract the flavor. It will float to the top of the bottle because it’s lighter than PGVG. It also evaporates quickly. Best to make your mix and steep. Take the cap off the mix and give the bottle a little squeeze to vent the alcohol off. Re cap and do it again every couple of days till the harshness is gone.


What he ^^^ said i had to do it with my rf sc. if not it has a bite to it
