Dry and moist nicotine pouches differ in one measurable thing: how much water is in them. The industry’s own convention puts a dry pouch below 10% moisture by weight and a moist one above 40%, with “semi-dry” in between. That number changes the pouch’s weight, its shelf life, and — the brands flatly contradict each other here — how quickly the nicotine arrives.
“Dry” and “moist” are two of the least explained words on a can. They are not marketing inventions, though: there are published thresholds, there are two official reference pouches built to sit at either end of the range, and there are measured figures for named brands. What there isn’t, anywhere, is a regulator who defines any of it — so the words mean exactly what the manufacturers have decided they mean.
The two words have real numbers behind them
The clearest definition comes from Swedish Match’s own patent filings. EP 3 330 191 A1, published 6 June 2018, states it plainly: “dry snuff has a moisture content of less than 10 wt% and moist snuff has a moisture content of above 40 wt%.” The same document adds that “Semi-dry products having between 10% to 40 wt% moisture content are also available.”
That was written about tobacco snuff. A later Swedish Match filing, EP 4 404 775 B1 (priority 2021, published 10 September 2025), carries the identical three-band scheme across to tobacco-free pouches: “dry pouched non-tobacco products for oral use…have a final moisture content of less than 10 wt%”, “Semi-dry pouched…have a final moisture content between 10 wt% and 40 wt%”, and “moist pouched…products have a final moisture content of above 40 wt%, such as from 40wt% to 60wt%”.
So: under 10% dry, 10–40% semi-dry, over 40% moist. Those are the numbers the people who make the things use internally. No law anywhere adopts them, and no can prints them.
There is an official reference pouch at each end, and its data sheet is public
This is the part almost nobody writing about pouches seems to know. CORESTA, the tobacco-science standards body, commissioned two nicotine pouch reference products, distributed by the University of Kentucky’s Center for Tobacco Reference Products. They are named, literally, “Dry” and “High Moisture”. Their data sheets are published, and both carry the note “Reference values generated on: September 25, 2024”.
| Reference product | NP1 Dry | NP2 High Moisture |
|---|---|---|
| Oven volatiles (moisture), % | 2.2 ± 0.2 | 47.07 ± 5.38 |
| Nicotine, mg per gram | 15.096 ± 0.282 | 15.4 ± 1.6 |
| Nicotine, mg per pouch | 6.006 ± 0.345 | 10.7 ± 1.1 |
| Pouch weight, g | 0.398 ± 0.024 | 0.6926 ± 0.0503 |
| pH | 8.25 ± 0.25 | 9.10 ± 0.10 |
| Made by | Swedish Match, May 2024 | British American Tobacco, January 2024 |
Both data sheets give the same ingredient line: “Fillers, pouch material, nicotine, pH adjuster, stabilizer, water and sweetener”. The homogeneity study records who produced each one and that moisture was measured by CORESTA method CRM No 76, at “an oven temperature of 99 °C ± 1.0 °C…instead of 100 °C ± 1 °C”.
Two things about that table are worth sitting with. The first is the gap: 2.2% against 47.07%. These are both nicotine pouches, both sold-format products from the two biggest makers in the category, and one of them is more than a fifth water by weight and the other is almost dry powder. The second is that the mg/g figures are nearly identical.
Why “15 mg/g” means two different pouches
Work the arithmetic on that table — this is my calculation from the published figures, not a claim either data sheet makes. Both reference pouches sit at roughly 15 mg of nicotine per gram. But the dry one weighs 0.398 g and the moist one 0.6926 g, so the dry pouch delivers 6.0 mg and the moist one 10.7 mg. Nearly double, at the same mg/g.
It goes further. Because 47% of NP2’s gram is water, its nicotine per gram of dry material is roughly twice NP1’s. A mg/g figure is measured “as is”, water included, which means it is not comparable across a dry and a moist product unless you also know the water content — and no can tells you. If you only ever read one thing off the label, read mg per pouch, not mg per gram.
The published literature has the same problem and at least one paper says so out loud. Jablonski, Cheetham and Martin’s market survey in Separations 9(3):65 (2022) states: “The results were not corrected for any moisture content since our aim was to examine the consumer’s potential exposure during use.” That is a defensible choice for an exposure study and a trap for anyone using the numbers to compare products. The paper was “supported by Enthalpy Analytical, LLC with internal funds”, and the authors disclose that Enthalpy is “a commercial testing laboratory…[which] provides services to a wide range of clients including tobacco manufacturers and regulatory authorities”.
What named brands actually measure
One published study measures moisture on named products and puts numbers on the split. Platt et al., “Dissolution and physical characterization of oral nicotine pouch products”, Scientific Reports, published 6 January 2026, tested seven mint products “with nicotine levels between 6 and 9.4 mg per pouch based on the can label”. Its own framing: “These brands were selected to represent both dry (on!, Zyn, Velo, Dryft, Rogue) and wet (Volt, Loop) pouch types.”
The measured moisture: “Zyn (3.52% MC), Dryft (3.71% MC), on! (4.48% MC), and Velo (6.67% MC) had the lowest moisture levels.” And: “In contrast, Rogue, Loop, and Volt exhibited much higher moisture contents of 14.70% MC, 26.64% MC, and 37.18% MC.” Moisture was measured as oven volatiles on “a HE53 halogen moisture analyzer…at 80 °C for 10 min in triplicate”.
Read that funding line before you read the results. The paper states: “This research was funded by Altria Client Services LLC, an affiliate of Helix Innovations LLC, the manufacturer of on! nicotine pouches”, and the authors were Altria employees at the time. One of the seven products tested belongs to the funder. I wouldn’t throw the measurements out for that — they are the only per-brand moisture figures in the peer-reviewed record — but a study run by one competitor on six others is not a neutral referee, and the ranking it produces should be read with that in mind.
Note also what those figures do to the dry/moist thresholds. On the Swedish Match convention, none of the seven is a “moist” pouch: Volt’s 37.18% is still semi-dry. Four of them are genuinely dry. The commercial words and the technical bands do not line up.
Does dry or moist hit faster? The brands cannot agree
Here is where the category gets genuinely interesting, because the claims contradict each other and one of the sources is reasoning from chemistry rather than copywriting.
A patent originally filed by NCP Nextgen AS and assigned in 2022 to Philip Morris Products S.A., US 11,096,412 B2, claims “A nicotine pouch composition…having a water content of at least 15 % by weight”. Its reasoning is explicit. On the problem with dryness: “the present inventors found that a too low water content contributed to an incomplete wetting of the pouch composition. This typically resulted in dry formulation with lumps, i.e. an undesirable mouthfeel.” On speed: “Having a water content within the scope of this invention may facilitate a fast release within the initial fast release period, such as within the first 120 seconds, since the pouch is already wetted or partly wetted.” In other words: moist is faster, because it does not have to borrow saliva first.
Nordic Spirit, which is JTI’s brand, agrees on direction in its own dry-versus-moist page (dated 2 April 2026) — moist gives “quicker flavour release” and “Nicotine release: Faster, near immediate once placed”, while dry offers “a gradual release of nicotine”. It also claims dry pouches last “15-20% longer” and produce “Very low drip” against “Moderate drip”. None of those numbers is sourced on the page, and it is brand marketing, not evidence.
Now compare the product page for Killa DRY Frosted Mint, which says its dry pouch is a “Product with very quick release of nicotine. Gives a fast, immediate effect” and is “suitable for those who like a drier pouch”. That is the opposite claim, for the opposite formulation. (The same page also gives two incompatible sets of its own specifications — 0.6 g and 9.6 mg per pouch in one place, 0.7 g and 11.2 mg in another — so I would not lean on it for numbers either.)
Where does the measured evidence fall? With moist being slower, not faster. Platt et al. found: “Volt and Loop, classified as wet pouch products, have higher moisture content and exhibited the slowest nicotine release profiles. This suggests that the presence of water and humectants in wet pouches may play a role in nicotine dissolution, a relationship worth further investigation.” And on the other end: “The highest release profile was obtained for Zyn nicotine pouches, followed by on! and Rogue…The slowest release rate was obtained for Loop nicotine pouches.”
So the one study points the other way from the one patent, and both point away from parts of the marketing. Be clear about what the study is measuring, though: dissolution in a laboratory vessel, not nicotine crossing a person’s gum. And it is a single industry-funded paper. My honest read is that the direction of the moisture effect is unresolved, that a “fast” or “slow” claim on a can is not currently backed by anything you can check, and that the humectant content — glycerol, propylene glycol — is probably doing as much work as the water. What the pouch does to you is governed far more by pH and the free-base fraction than by whether it feels damp.
The vocabulary is borrowed from snus, and it meant something specific there
“White” and “original” portions came first, and the same Swedish Match patent explains them mechanically. Pouched products “may be post-moisturized after pouch formation or not post-moisturized after pouch formation”; “Non-post-moisturized pouched products are sometimes referred to as ‘white snus'”, while post-moisturised ones are “original snus”. A white portion is not a different recipe so much as a pouch that never got sprayed.
Skruf, which is Imperial Brands’, says the same thing in one line on its own product pages: “White betyder att portionspåsen är mindre fuktig” — white means the portion pouch is less moist. Its Original White page (modified 27 February 2026) publishes weight and nicotine — 0.9 g per pouch, 12 mg/g, 11 mg per portion, 24 pouches, 21.6 g can — and no moisture figure at all.
The same patent also concedes the cost of skipping the spray, which is the most candid thing any manufacturer says about this: “The initial amount of flavours and/or nicotine released from the pouched tobacco may be experienced by the consumer as unsatisfactory or even negligible. This problem is often more pronounced for non-post-moisturized oral pouched snuff products.” If a white portion feels like it takes a while to wake up, the maker’s own filing says that is real. There is more on that trade-off in white portion vs original portion and on the all-white pouch naming in what “all-white” really means.
Shelf life is the one place dry clearly wins
Swedish Match’s own FAQ gives numbers, and they are the cleanest dry-versus-moist comparison the company publishes: “When stored correctly, the shelf life for moist loose snus is 14 weeks, for moist portion-packed snus 20 weeks and for the dry assortments 30 weeks.” The same page: “Snus is perishable and must be stored in a refrigerator for best shelf life”, and “For longer storage, we would recommend freezing, which is excellent up to one year.”
Less water, slower ageing, longer life. That is also why modern dry pouches are sold as room-temperature products. ZYN’s storage page (14 August 2025) says “ZYN pouches are developed for stability at ambient temperatures”, recommends “Maintain storage between 15-25°C”, and actively warns off the fridge: “Refrigerators create humid environments. Repeated temperature changes when removing/returning cans can cause condensation.”
Worth a caveat, though. The CORESTA data sheet for the dry reference pouch still asks for cold storage — “in a cool, dry place (~4° C)”, and at or below −20°C if it will not be used within about two weeks. So “dry pouches don’t need the fridge” is a claim about a commercial product’s formulation and packaging, not a property of dryness itself.
On drip, I can find no evidence at all. The only mechanistic source I found is a pouch-manufacturing patent now assigned to British American Tobacco, US 2010/0200005 A1, and it is about the fleece staining during production and storage rather than anything happening in your mouth: “Due to the high moisture content of snus, and particularly when influenced by storage or packaging conditions, liquid can seep from the snus and result in dark or brown coloured spots on the fleece.” Plausible that the same physics produces more drip in use. Not demonstrated by anyone.
Dry vs moist, side by side
| Dry | Moist | |
|---|---|---|
| Moisture, industry convention | Under 10% by weight | Over 40% by weight |
| Reference product figure | 2.2% (CORESTA NP1) | 47.07% (CORESTA NP2) |
| Named brands measured as this type | ZYN 3.52%, Dryft 3.71%, on! 4.48%, VELO 6.67% | Volt 37.18%, Loop 26.64%, Rogue 14.70% |
| Pouch weight at similar mg/g | Lighter, so fewer mg per pouch | Heavier, so more mg per pouch |
| Feel | Firm, powdery, “dry to the touch” | Softer, damp, slightly larger |
| Release speed | Disputed; one study measured dry products releasing fastest | Disputed; a Philip Morris-owned patent argues pre-wetted is faster |
| Shelf life (snus, maker’s figures) | 30 weeks | 14 weeks loose, 20 weeks portioned |
| Storage | Modern dry pouches sold as ambient-stable | Refrigeration recommended |
| Defined by any regulator | No | No |
Nobody regulates any of this
I went looking for a legal definition and there is none. Sweden’s binding regulation on snus and snus-like products, LIVSFS 2024:2 (in force 1 April 2024), sets limits for lead, aflatoxins, benzo(a)pyrene and nitrosamines — and says nothing about moisture, water activity or portion types. The Swedish Food Agency’s guidance article on snus, snus-like products and chewing tobacco (last updated 13 August 2026) does not mention moisture either. Germany’s Federal Institute for Risk Assessment, in its health risk assessment of nicotine pouches (7 October 2022), assesses pH and free-base nicotine in detail and does not discuss moisture at all.
So the three-band scheme is an industry convention documented in patent filings, operationalised by CORESTA’s reference products, and used loosely and inconsistently on cans. Two brands can both write “dry” and mean products 10 percentage points apart, and neither is breaking a rule.
Frequently asked questions
Is a dry pouch weaker than a moist one?
Not per gram, usually — but often per pouch, because it weighs less. On the CORESTA reference pair, the same ~15 mg/g gives 6.0 mg in the dry pouch and 10.7 mg in the moist one. Compare mg per pouch.
Which one comes on faster?
Unresolved, and the brands say opposite things. One industry-funded dissolution study measured the driest products releasing fastest; a Philip Morris-owned patent argues a pre-wetted pouch releases faster in the first two minutes. Neither settles it, and neither measures nicotine in blood.
Do dry pouches need refrigerating?
ZYN says no and specifically warns against the fridge for its pouches. Swedish Match says refrigerate snus, and gives dry snus a 30-week shelf life against 14–20 weeks for moist. Follow the can’s own storage line.
Do dry pouches drip less?
Brands claim it; I could not find a single measurement of drip, in any product, from anyone. Treat it as an untested claim.
Is “white” the same as “dry”?
No. “White” in snus means the portion was not post-moisturised after the pouch was formed — a manufacturing step, per Swedish Match’s patent. A white portion is made drier — the post-moisturising spray is skipped — but no published figure shows it measures drier: the patent’s ranges for the two overlap, and FDA described a white-versus-original moisture decrease as “small” without printing the number. Either way it is nothing like a 2%-moisture dry pouch.
Can I dry out a moist pouch myself?
You can leave a can open and it will lose water, and you will also lose flavour and shorten its life; ZYN’s own storage page lists “Dried-out pouches (harder texture, diminished flavour)” as a fault, not a feature. Nobody publishes anything on what that does to nicotine delivery.
