Flavor Apprentice formaly known as Perfumers Apprentice Concentrates are known for their high quality and great taste. No nasty colourings or additives that will foul up atomizers.
Use these to blend your own e liquid to be vaped with your electronic cigarette.
Everyone's taste will always be different, and that is why it is best to use a flavour concentrate to mix your own flavours for vaping, however, you also need to remember, using too high a percentage in your mix will make any flavour taste really bad, too perfume like, and just plain eew.
To minimise this issue, you are advised to use between 5-10% MAX for any flavour apprentice flavours when testing.
Also remember, the longer you wish to steep your juice, the lower the percentage required.
Warning: These concentrates are not to be vaped straight, they are to be mixed with PG or VG.
