The Flavor Apprentice Root Beer- DIY E-Liquid Flavoring
From TFA website:
water soluble
This root beer needs special treatment to bring out the best flavor. It needs to age at least a week after you blend it with your mix! We almost did not proceed with this flavor because it does have an unpleasant taste and aroma at first. (It is very strong)
But then the few customers that we sent it to emailed me and said that they really liked it after it aged,
and to please continue it.
So, this is another flavor that will probably appeal to some people, and not to others.
We have also heard from Carrie! "My husband and I have been messing with flavors for awhile and have found that about 2 drops of menthol added to root beer flavor wakes it up and gives it that bright root beer flavor. 3-4 drops make root beer barrel flavoring!"
Thanks Carrie!
