What Is 70/30 Vape Juice
The 70/30 on a vape juice label tells you the VG to PG ratio inside the bottle. VG is vegetable glycerin and makes up the thicker part of the liquid. It's what creates the vapour and gives a smoother inhale. PG is propylene glycol and carries the flavour, plus it adds throat hit.
A 70 VG 30 PG e-liquid leans heavily towards the VG side. You'll get noticeably more cloud and a softer draw compared to a 50/50 vape juice where the throat hit is sharper and the vapour thinner. Some high VG e-liquids go up to 80 VG 20 PG for even more vapour. The 70/30 ratio is still the most common you'll see in UK shortfills.

Best Kits and Coils for High VG E-Liquid
High VG vape juice runs best through sub ohm coils at 0.2Ω to 0.5Ω. These coils have bigger wicking ports that let thicker 70/30 liquid soak through without dry hits. Put high VG juice into a pod kit with a 1.0Ω or 1.2Ω coil and the liquid won't wick fast enough. You'll burn through coils quickly and get a dry, harsh taste.
For kits, stick to sub ohm kits or tanks that take coils below 0.5Ω. Rebuildable tanks like RTAs and RDAs handle high VG well because you control the cotton and airflow yourself.

If you're using a pod kit, 50/50 vape juice or nic salts are a better fit. Those thinner liquids wick properly in smaller coils without gunking them up.
High VG Shortfills and Nicotine Strengths
Most high VG juice comes as a shortfill, a larger 100ml or 50ml bottle left short of nicotine so you can add a nic shot and mix it to your strength, usually landing at 3mg or 6mg. If you want zero nicotine, they vape as they are straight from the bottle. True high VG nic salts are rare, because salts are usually mixed at 50/50 to wick in small pod coils, so if you specifically want salts the nic salt range is the place to look. For plain 0mg freebase shortfills to mix yourself, those sit alongside this collection too.
The 2026 Vape Tax and Stocking Up
The new Vaping Products Duty lands on 1 October 2026, adding £2.20 of duty per 10ml of e-liquid whatever the nicotine strength. Bigger bottles feel it most: a 100ml high VG shortfill carries ten times the duty of a 10ml, so these are the bottles set to rise the most. There is a six-month sell-through window, so stock made before October can still be sold up to 1 April 2027, which makes now a sensible time to stock up on the larger shortfills before the change. Our guide to the 2026 vape tax breaks down what is changing and when.
