PG vs VG in a Sealed Disposable: What the Ratio Actually Changes
Ask which PG/VG ratio you should buy and a hundred articles will answer. Almost all of them are, without saying so, about refillable e-liquid — a world where you pick a bottle with the split printed on the label. A sealed disposable is not that world. You do not choose the ratio, you cannot read it, and nobody who makes these devices publishes it. Here is what the ratio genuinely changes, why the number is unavailable, and which levers really are printed on a listing.
What PG and VG actually do
Propylene glycol and vegetable glycerine are the two carrier liquids essentially every nicotine e-liquid is built on; the flavourings and the nicotine ride in them. The two behave very differently — it is only the ability to pick between them that disappears in a sealed device.
PG is the thin one. It flows easily and carries flavour compounds well — food-grade concentrates are generally suspended in PG to begin with, and PG has almost no taste of its own, so you notice the flavour rather than the base. It soaks into a wick quickly, and it is the component behind the sharper, more defined sensation at the back of the throat. What it does not do is make much vapour.
VG is the thick one, closer to syrup. It produces the dense cloud a disposable is built to deliver, and it draws noticeably smoother. It is also faintly sweet in its own right, which cuts both ways: that sweetness rounds a flavour off pleasantly, but can blur fine detail in a complex blend. Being viscous it travels through wicking material more slowly, and retailer technical guides note VG-heavy liquid leaves residue on a coil faster.
| What you notice | Leans PG | Leans VG |
| Throat sensation | Sharper, more defined | Smoother, softer |
| Visible vapour | Lower | Higher, denser |
| Flavour character | Sharper, more separated notes | Rounder, more blended |
| Background sweetness | Effectively none | Slight, from the base itself |
| Wicking speed | Faster | Slower |
| Residue build-up on the coil | Slower | Faster |
Why nobody publishes the ratio — including us
We checked the manufacturer pages again this week rather than assume. IGET's product pages for the Bar, Bar Pro, ONE and Moon publish a tidy spec block: puff rating, coil type and resistance, battery, dimensions, materials, weight. What is on none of them is e-liquid volume, nicotine strength, or any hint of a PG/VG split — consistent across the whole official range, not an oversight on one page.
So if a retailer confidently quotes a ratio for a sealed disposable, ask where they got it, because the manufacturer did not tell them. We do not print one on any listing we sell, for the simple reason that we would be inventing it — and batch formulations change quietly over a product's life, so even a once-accurate figure has a short shelf life. Same pattern as in how to read a vape listing: some fields are published facts, some retailer convention, and telling them apart is most of the skill.
The industry does not even agree on the direction
The general guidance published about disposables contradicts itself. One established retailer guide argues the format must sit balanced in the middle: liquid too thick for the small wicks in a compact, low-power device cannot keep up with your draw, while liquid too thin tends to seep past it. Another argues the category leans VG-heavy, because dense vapour and a smooth draw is what these devices are sold on. Both are sound; neither is a spec sheet.
The levers that are actually knowable
Nicotine strength
This is on our listings and it shapes how strong a device feels more than any base ratio would. Our IGET Moon listings are 4%; our other main lines are 5%. If a device feels sharper than you want, move this dial first — see nicotine strength explained. And note that salts versus freebase is a completely separate axis from PG/VG, not another name for it: one is the carrier liquid, the other the chemical form of the nicotine in it. See salts vs freebase.
Coil resistance
Published, verifiable, and directly related to how much vapour a device makes. IGET publishes a 1.2Ω mesh coil for the Bar and Bar Pro, 1.35Ω mesh for the Moon, and a 0.6Ω dual mesh for the ONE. That lower-resistance dual mesh predicts a bigger, warmer draw far better than any ratio guess — see mesh coils explained.
How you draw
Free, and most people never adjust it. A tight mouth-to-lung pull and a long direct-lung pull give different vapour volume and flavour intensity from the identical device — see our MTL vs DTL draw guide.
Flavour family and cooling
The words on the label are the most reliable signal you have. Ice level is readable straight off the name once you know the vocabulary — see reading ice in flavour names — and the split between fruit, candy and ice is in our flavour families guide. If a flavour name tastes different across two brands, that is a formulation difference, not a ratio you could have looked up: here is why.
Buy one before you buy ten
Since the ratio is neither choosable nor knowable, the sensible move is empirical. Buy one device, run it properly, and note what you noticed — vapour thinner than you like, flavour blurred, throat sensation not sitting right? Then go deep on what worked. Alibarbar Ingot launched its full single-flavour range with us today, which makes it an easy one-off try.
Once you have found your line, free shipping kicks in on orders of 10 or more — so build a ten that is not ten of the same thing. Our notes on bulk buying and single-fruit vs triple-fruit blends help there.
