PG vs. VG

PG vs. VG

PG (Propylene Glycol) vs. VG (Vegetable Glycerin)

PG and VG are the odorless liquids that are combined with flavor and nicotine to create e-juice. Once heated they produce vapor that can be inhaled. Each has a different consistency to each other, and also have a slightly different taste as well as a distinct mouth and throat sensation when vaped. You’ll typically order your ejuice in a ratio that will suit your style. Both VG and PG have been “generally recognized as safe” by the FDA.

PG is used to provide a ‘throat hit’ when vaped, which some users claim is similar to the sensation experienced when smoking tobacco. It also carries flavor more effectively than VG, meaning it’s the most commonly used suspension fluid for flavor concentrates and nicotine. Beware that a high level of PG can be irritating to your throat.

VG is a natural chemical, derived from vegetable oil, so is safe for vegetarians. It is commonly used in ejuice to give a ‘thick’ sensation to vapor. It has a slightly sweet taste and is considerably thicker than PG. The hit from a high VG fluid is a lot smoother than with PG, making it more suitable for sub-ohm vaping. Since Vg is thicker, high ratio of VG clogs up coils more rapidly.

What Ratio You Should Use?

  • More Throat Hit & Less Cloud (Higher PG) – If you enjoy a sharp throat hit when vaping, then you’ll prefer a high PG ratio. Also, PG carries flavor a bit better than VG, so the flavor will be slightly improved too.
  • More Smoothness & Bigger Cloud (Higher VG) – High VG fluid tends to give a much smoother feeling on the throat, with a more substantial mouthfeel. The flavor can be muted in VG and this can be countered by using more power to produce more vapor. NOTE: Be careful to stay within the voltage/wattage limits of your ecigarette to avoid dry hits or damaging your equipment.
