PG vs VG in Vape Juice: What Adult Vapers Should Know

Overview

What PG (propylene glycol) does

PG is the thinner of the two. It carries flavour well and delivers more of a throat sensation, the familiar feel many adult users describe as a throat hit. Our throat hit guide explains throat hit in detail, and it is largely the PG level that drives that feeling. PG is common in food and personal-care products and is widely used in vape blends.

What VG (vegetable glycerin) does

VG is thicker and sweeter. It produces more vapour and gives a smoother, softer draw with less throat sensation. Blends with more VG tend to feel gentler and cloudier. The two work together: PG for flavour and feel, VG for vapour and smoothness.

What the ratio means in practice

A higher-PG blend feels sharper and carries flavour forward; a higher-VG blend feels smoother with bigger clouds. Neither is right or wrong, it is about the feel you prefer. Our nicotine salts guide article on nicotine salts and our salt vs freebase guide guide on salt versus freebase add more context on how blends are built for different preferences.

In a sealed disposable

Our ALIBARBAR and UMIN disposables are pre-filled with a fixed, balanced blend chosen for consistent flavour and vapour, so you cannot tweak the PG or VG yourself. Knowing the balance simply explains why one device feels smoother or more intense than another. Our authentic taste guide on what makes a flavour taste authentic ties it together.

Choosing by feel

If you want a stronger throat feel, blends known for it will suit you; if you want smoother, look to the gentler end. Our best flavours guide flavour guide and our fruit flavours guide top picks help you match a profile to the feel you like, and our palate matching guide helps match a flavour to your palate.
