Thus the importance of steeping. Flavors change as a mix becomes more miscible.
The best thing that you, as a brand new mixer, can do - - - IS - - - do a mix - - - then set it aside so it steeps for a good 10 - 14 days for 10ml mixes using fruits.
Expect to steep for 30 days with bakery type flavors, creams and custards.
Leave your mix alone - - - don't
vape any - - - until it is well steeped. Then, and only then,
vape and judge your mixes. Tweak them as needed ONLY after a good long steep!!!
All (ALL) mixes change over time as flavors/VG/PG/nic develop into a homogeneous mixture.
