FA is more creamy and malty. TFA is more sweet and aromatic.
Very different flavors. TFA when you want that marshmallow sweetness, FA when you want marshmallow creamy malty mouth feel. It provides a thick sweet texture to your mix (like that of a marshmallow surprisingly!). If you want to add some sweetness and give your juice a more full body, this is a good flavor to add. It’s almost got a bit of a “nutty” flavor from the marshmallow so be wary of that if you just want sweet. I use this at low (.5-2)%
Blends your fruits nicely. To add sweetness stick under 2%.
Preferred single flavor mix: 2.0%
