The Flavor Apprentice Coffee (Clear) - DIY E-Liquid Flavoring

This version has a strong coffee flavor, but the liquid is clear

water soluble

this is a very strong flavor that is like black, unsweetened strong coffee, 
do not try to evaluate just by smell!!
it should also be used at less than 5%

Note: Not everyone likes this flavor! please try a small size to see if you like it before buying
larger bottles.
