Vaping terminology can be a bit confusing to vaping newcomers. Even those who’ve been in the game for a bit may have trouble remembering everything there is to know. Two terms you should become familiar with are PG and VG. These are the two main base components of all e-juices.
What exactly is PG?
Propylene glycol(PG) is an odorless, colorless chemical that is the most popular of the two fluids as it provides more of a “throat hit,” something many ex-smokers are looking for. PG has a lower density, which allows you to go a bit longer between coil changes, and it holds flavor better than VG. However, it’s been known to have a larger incidence of allergic reactions, varying from dry mouth to tingling sensations in the throat.
What exactly is VG?
Vegetable glycerin (VG) is thicker than propylene glycol, so it tends to require more cleaning and tank maintenance. VG by itself has a slightly sweet taste that it lends to the overall flavor of the e-juice. Although it’s less allergenic than PG, VG has been known to cause phlegm buildup in the throats of some vapers. The throat hit sensation is considerably less with VG, but many vapers find it to be smoother despite the lesser throat hit and tend to appreciate the additional vapor production.
How Do I Choose Between PG and VG E-juice?
The decision will ultimately depend on your sensitivities, your device, and what you’re looking for in your vaping experience. You also don’t have to choose one or the other. For instance, many e-juices use a combination of the two, such as 70% VG and 30% PG, which is the optimum ratio to provide a decent throat hit while preserving flavor and vapor production.
Consider the following when looking for a PG/VG ratio:
Do you want a better throat hit or more vapor? For an optimal throat hit, go for a higher PG juice. For more vapor, choose a juice with higher VG.
Do you want to keep your vaping on the DL in public? E-juices with higher PG content produce less vapor upon exhale and are better for vapers who want to keep their vapor to a minimum in public places.
What flavor of juice do you prefer? Tobacco, fruity, or beverage flavors do better with more PG, whereas custards, yogurts, or cream flavors work well with higher VG contents.
