Shortfill (Shake and Vape) and PG/VG Calculator


If you have read our Shortfill (Shake and Vape) and Nicotine Calculator, you can understand how much nicotine is in your e-liquid. When you add base to a  Shortfill (a.k.a. Shake and Vape or S&V), however, you might also want to pay attention to the PG/VG ratio.

What kind of base do you need to add to a Shortfill? And how does it affect the PG/VG ratio?

As you may know, Propylene Glycol (PG) and Vegetable Glycerin (VG) play an important role in your vaping experience. In short, PG is a flavour carrier. In combination with nicotine, PG also contributes to the throat-hit. VG, on the other hand, determines the amount of vapour and its thickness.

Our base is available with different PG/VG ratios. This means you can slightly tweak the final composition of your e-liquid. For instance, suppose you have a 50ml shortfill with 30%PG/70%VG (in a 60ml bottle). Ignoring flavourings, this essentially means you have 15ml of PG and 35ml of VG. If you now add 10ml of PG, you end up with 25ml of PG and 35ml of VG. Given that you now have 60ml of e-liquid, this roughly boils down to 42%PG/58%PG.

Of course, you can only change the original composition slightly, but it might be enough to use a shortfill in your favourite set-up. You can look at more examples below:

  • Shortfill (50ml) with 50%PG/50%PG + 10ml base with 100%PG = 60ml e-liquid with 67%PG/33%PG
  • 50ml Shake and Vape with 50%PG/50%PG + 10ml base with 50%PG/50%PG = 60ml e-liquid with 50%PG/50%PG
  • 50%PG/50%PG S&V with 50ml + 10ml base with 100%VG = 60ml e-liquid with 33%PG/67%VG
