E-liquid is made up of a combination of Propylene Glycol (PG) and Vegetable Glycerine (VG). Each adds different qualities to a liquid and the PG/VG ratio of an e liquid is very much down to personal preference.
Vegetable Glycerine (VG) is a thick, gloopy liquid that makes for a thicker liquid, more vapour and a fuller feeling vape.
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’.
What is the best PG VG ratio for me?
PG/VG ratios have a big impact on flavour levels, and of course, vapour levels. If you have a 50/50 juice, and a 70/30 juice with the same flavour quantity, you’ll get a noticeably different flavour. The ratio that you eventually choose will be based on the following:
Taste – The flavour of PG based e-liquid tends to be more intense. VG based liquids have more muted flavour.
Hit – PG gives you a better “throat hit” than VG. Of course you will still get a hit from VG, but it’s much smoother.
Vapour – If you’re looking to create huge clouds of vapour (cloud chasing), then aim for a VG-based e-liquid.
Your Device – Most everyday vapers use standard tanks, which work best with thinner PG-based e-liquids. They are are less likely to clog up the tank and are more easily absorbed into the wick. VG based liquids would cause dry hits if you try them in a standard tank.
The most popular e-liquids use varying ratios of both VG and PG to ensure a good all-round experience. The most common ratios are either 50/50, 60/40, or 70/30 depending on the user’s preference, although 100/0 ratios are also available. Whichever PG VG ratio you choose is your decision, with different ratios offering different benefits. Feel free to experiment, weigh up the pros and cons and enjoy your journey to a better vaping experience.
Liquid made of all PG is very thin. It has a harsh throat sensation and produces poor vapour. I have used 100PG e-liquids in situations where I want to vape without attracting attention.
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
A good combination of vapour production, throat-hit, device compatibility and flavour accuracy. This is the ‘sweet spot’ for most vapers. 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 and rebuildable tanks. 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.
