Perfumer’s Apprentice Sour Concentrate is malic acid in a 20% dilution with propylene glycol and is intended to be used as a flavor enhancer, providing a sour note to e-liquid recipes. When used with other flavors, this concentrate gives a sour candy effect and can work well to balance out mixes that need less sweetness. Perfumer’s Apprentice Sour Concentrate mixes really well with fruit flavors, brightening them up and adding tartness if required, but be careful to use this concentrate sparingly as a little will go a long way.
We suggest mixing most Flavor Apprentice concentrates at approximately 5-10% initially and then adjusting to your personal taste.
