Keeping a tasting log from day one

Keep a tasting log because your memory of a pouch is contaminated by the order you tried it in, the label you read first, and the minute you happened to judge it. Sensory scientists have known this for decades and built a standard set of fixes: a fixed field list, an anchored scale, a rest interval, and recording while you taste rather than afterwards. Eight steps below, no app required.

There is no official method for this. The closest thing that exists is a tobacco-industry consortium conceding that agreed best practice does not yet exist — its own review “highlighted unclear recommendations or best practices from guidance documents” issued by regulators on how subjective outcomes should be assessed. So the method below is borrowed from food sensory science, which has spent fifty years working out how badly people misjudge what they taste.

Two warnings before the steps. This is a log of what you like, not a measurement of anything about your health. And a log is only worth keeping if it is short enough that you actually fill it in — every step below is designed around that.

Step 1: write down the fields, not the prose

A paragraph about how a pouch felt is unusable three weeks later. A row is usable. The fields worth having:

• Product and market. Not “ZYN 6” — the brand, the variant, the size name and the country you bought it in. The same brand runs different strength ladders in different markets: ZYN’s Italian support page lists strengths “ranging from 1.5mg to 11mg”, while its UK page runs from 3 mg to 16.5 mg.
• Labelled strength and its unit. Every manufacturer page I could reach labels in milligrams per pouch — ZYN says “Each ZYN pouch contains a specific amount of nicotine, measured in milligrams (mg).” and VELO lists “approximately 4 milligrams or 7 milligrams of nicotine per pouch”. Research papers usually use milligrams per gram instead. Note which you are copying, because the two are not interchangeable.
• Format: dry or moist. This is the field most people skip and it predicts more than the strength does. ZYN’s own guidance: “ZYN Mini nicotine pouches are dry, offering a more gradual release of nicotine” while “ZYN Regular nicotine pouches are moist, offering a more immediate release of nicotine”.
• Flavour family — mint, wintergreen, citrus, coffee, tobacco-free “tobacco”. One word.
• Hold time, in minutes. The single most important number in the log. See step 5.
• Time of day, and hours since your last pouch. Overnight abstinence changes how a pouch feels, so an 8 a.m. entry and a 4 p.m. entry are not comparable.
• Four scores — burn, taste, delivery, physical fit — and nothing else. I use those four because they fail for different reasons and have different fixes, which is the argument I make at more length in how to judge whether a pouch suits you.

Two fields to leave off. Moisture percentage is unobtainable — when the FDA reviewed on! PLUS, the manufacturer said “The applicant did not provide target specifications and lower range limit for moisture content” because these “are not routine design parameters for product characterization”. And pH, which matters enormously to how much nicotine you absorb, is published by nobody per product. Leave both off; you cannot fill them in.

Step 2: fix the scale before you use it, once

Decide your scale on day one and never change it: a score only means something relative to the other scores on the same scale. The convention in sensory work is a numbered scale with written anchors at both ends, set out in ASTM E3041, Standard Guide for Selecting and Using Scales for Sensory Evaluation.

There is a published, anchored instrument used on actual nicotine pouches that you can copy directly. A 2026 clinical study asked “How much do you like the product, overall?” on a 0–100 line where “0 mm represented “really dislike” and 100 mm represented “really like”.” A 0–10 version of that, written on the page before you start, is better than any score you invent in the moment.

One finding from that study is the best reason I know to keep a log at all: overall liking barely moved across an 11 mg and a 20 mg product at ten, twenty and thirty minutes. Nicotine strength did not predict whether people liked the thing. If dose does not tell you what suits you, you have to measure it.

Step 3: write your expectation down before you open the can

This is the step that feels silly and does the most work. Reading a label changes what you then taste — not what you say about it, what you perceive. The cleanest demonstration is from coffee rather than pouches, and I am not going to pretend otherwise. In a 2025 study, “A total of 180 specialty coffee consumers participated in a within-subject tasting experiment” in which the same coffee was served three times under three different processing labels. The result: “the perception and acceptance of the same coffee sample was highly dependent on the label description presented when the coffee was served”. Identical liquid, different words on the card, different ratings.

Pouch marketing is dense with that kind of language — cooling, intensity, freshness, strength dots. Write one line of what you expect before you open the can. When the score matches the expectation exactly, you have learned something about the packaging rather than the pouch.

Step 4: record while it is in, not afterwards

A single score written down later is a summary of a changing experience, and it is usually a summary of its peak. A 2023 review in Molecules puts the problem plainly: “These measures made at a single time-point do not capture the full temporal sensory experience”. The discipline’s answer is time-intensity measurement — “the time-intensity method (TI) that makes it possible to follow the intensity evolution of a sensory attribute” — standardised as ASTM E1909.

You do not need to plot a curve. Two timestamps are enough: one at about two minutes, one at the end. Sensory researchers treat recording-as-you-taste and recording-from-memory as two different measurements and run studies to compare them — in one published protocol, “When using TDS, the evaluation task was concurrent to the tasting” while the other method was retrospective. I could not read the paper reporting which performs better, so I will not claim writing later is worse. Writing later measures something else.

Step 5: time the hold, and take the real score at the end

Hold time is the one variable in your log that genuinely changes the dose, and it changes it a lot. In a BAT-funded crossover study — the authors state that “all authors were employees of BAT, which was the sponsor and funding source of this study” — the finding was flat: “Nicotine delivery to the consumer increases with the duration of use.” Extraction from an 11 mg pouch ran 28.0% at ten minutes, 35.8% at twenty and 43.7% at thirty. Peak blood nicotine arrived later as the hold lengthened, roughly at the end of it.

So: record the minutes every time, or your delivery scores are noise. And take the delivery score at the end of the hold, because that is roughly when the peak arrives — an impression formed at minute two is an impression of the burn, not the dose.

The same paper’s review of the literature reports that typical single-pouch use falls in a ten-to-twenty-minute range and can run to an hour. Pick a standard hold — fifteen minutes is a reasonable default — and vary it deliberately rather than accidentally.

Step 6: one new product at a time, with a gap

Trying three cans in an afternoon produces three contaminated entries. This is the best-documented failure mode in the whole of sensory science. From a 2018 paper in Foods: “The sensory biases caused by the residual sensations of previously served samples are known as carryover effects”, and “The order of tasting can introduce a significant bias in sensory evaluations”. Worse, the bias has a direction — “the first sample often receives the highest score in a sequence of samples”. Your favourite pouch may simply be the one you tried first.

The remedy is what laboratories actually do: in a published protocol, between samples “a 30-s pause was imposed, during which consumers were asked to rinse their mouths with mineral water”. Thirty seconds is an interval for a sip of chocolate; a pouch sits in your lip for fifteen minutes and leaves a cooling agent behind. Leave a real gap — I would not score a second new product inside an hour of the first.

Step 7: rotate the order when you compare

If you are comparing two or three products deliberately, do not always start with the same one. Laboratories counterbalance the order — in the protocol above, samples were served “in a sequential monadic order according to a Williams Latin square”, which is a formal way of ensuring every product appears in every position across the sessions.

If you compare A against B today starting with A, compare them again another day starting with B. If the winner changes, the order was doing the work.

Step 8: read it back after two weeks, not two pouches

A log’s value is retrospective. Two entries tell you about burn and taste; they cannot tell you whether a strength suits you. Give it a fortnight of normal use, then read the whole thing in one sitting and look for the pattern rather than the extremes — which flavour family keeps scoring well, whether your good entries cluster at a particular hold time, whether the morning entries behave differently from the evening ones. Use the same descriptors throughout; that consistency is the only part of the formal sensory vocabulary standards (ISO 5492 and ISO 11035) that matters at this scale.

The mistakes I see most

Scoring in the first ninety seconds. That is a burn measurement wearing a delivery label. The peak arrives near the end of the hold.

Changing the scale halfway. A 7 in week one and a 7 in week three have to mean the same thing or the log is decorative.

Logging only the products you disliked. People reach for the notebook when something goes wrong, which produces a log of failures and no baseline.

Treating a label figure as a measurement. VELO’s own page says “approximately” before each milligram figure, and independent analysis of 70 commercial products found measured content “ranged from as low as 75% below the labelled value”. Log the number on the tin as what it is: the number on the tin.

Letting the log drift into self-assessment. Recording hold time and pouches per day is useful because those variables change what you absorb. Scoring yourself against a clinical dependence instrument is a different activity, it needs someone qualified, and a tasting log is not the place for it.

Troubleshooting

What you are seeing in the log	Most likely cause	What to change
Everything scores 6 or 7	The scale has no anchors, so you are drifting to the middle	Write the two end anchors down and re-read them before each entry
The first product you ever tried is still your favourite	First-position bias — the first sample tends to score highest	Re-score it late in a session against a product that beat it
Two cans of the same product score very differently	Different hold time, or different time since your last pouch	Check those two fields before blaming the can; standardise the hold
Delivery scores look random against labelled strength	They genuinely are not proportional — extraction, format and pH all intervene	Compare within one brand and format before comparing across them
Everything after the third pouch tastes the same	Carryover and adaptation	One new product per session, with a real gap
The score always matches what the can promised	Label expectation is leading the perception	Write the expectation down first, then score; look for divergence
You have stopped filling it in	Too many fields	Cut to product, hold time and the four scores. A short log that exists beats a thorough one that does not

A tasting log tells you which products you like and which you do not. It cannot tell you whether a product is safe — the FDA’s position on even its authorised list is that “There is no safe tobacco product, and those who do not use tobacco products should not start.” Keep it for what it is good for. If you are earlier than this, your first pouch step by step comes before any of it, and building a routine in your first month is the companion piece to this one.
