What PG/VG ratio is best?
Almost every e liquid is made up of a combination of Propylene Glycol (PG) and Vegetable Glycerine (VG). Each adds different qualities to a liquid and – much like flavour percentage – the PG/VG ratio of an e liquid is very much down to personal preference.
If you’ve never made e liquid before and use standard tanks (not drippers) we’d suggest starting off with around 70% PG and 30% VG.
Bear in mind that your nicotine and flavourings will be carried in either PG or VG, so should be treated as pure PG or VG for the sake of working out your final PG/VG ratio.
Propylene Glycol (PG) is a lot less viscous than VG, is a better carrier of flavours, soaks into atomiser wicks easier and gives a better ‘throat hit’.
Vegetable Glycerine (VG) is a thick, gloopy liquid that makes for a thicker liquid, more vapour and a fuller feeling vape.
We’ve never tried it, but liquid made of all PG would be very, very thin. It would probably leak out of most devices, be harsh and produce poor vapour.
Many mass-produced e liquids (the types available from convenience stores etc) are made at this ratio. It will vape ok in most devices but will tend to feel a little on the thin/insubstantial side. Experienced mixers would probably say it needed a bit more VG to ’round it out’.
70PG/30VG – 60PG/40VG
This is the ‘sweet spot’ for most vapers. A good combination of vapour production, throat-hit, device compatibility and flavour accuracy. We mix our own e liquid range at around 65PG/35VG.
A 50/50 mix will start getting fairly thick. It will provide very satisfying vapour, but might not wick too well in a lot of tanks.
60VG/40PG – 80VG/20PG
A mix around this ratio is likely to be very thick and won’t wick well on standard devices. It will be fine on drippers. If you do want a very VG rich mix using standard tanks, we would recommend thinning it with a little distilled water.
This mix can only be achieved with VG based nicotine and flavour concentrates. It could only be used with a dripper, or thinned with water. As PG carries flavour better than VG, it will probably be harder to get a good flavour with no PG at all.
