How to read an RTD can: UK rules, units and the allergen line

Under Regulation (EU) No 1169/2011, a UK label on a canned cocktail must give the name, the strength, the volume, any allergen and the business behind it. It may leave out the ingredients and the nutrition table. Read it in five steps, and the can tells you what is inside and how much alcohol it holds.

The guide

Start here.

A can must give five things, and the rest is the producer’s choice.

Read a can in this order: the name, the strength and volume, the allergen line, the base and the date. Article 9(1) of Regulation (EU) No 1169/2011 makes the name, any allergen, the net quantity, the date where one applies, the storage conditions, the business and the strength mandatory for a drink above 1.2% ABV. The ingredients and the nutrition table are not on that list for such drinks, under Article 16(4).

What a canned cocktail label says and what it does not, from Regulation (EU) No 1169/2011, Regulation (EC) No 110/2008 and the Portman Group’s Code

Alc. 5.0% vol.

What it tells you
The strength, measured at 20°C, to one decimal place
What it does not
How sweet or how heavy the drink is

250ml

What it tells you
The net quantity, which with the strength gives the units
What it does not
The units themselves; the producer may leave them off

Contains milk

What it tells you
The allergen, where the can has no ingredients list
What it does not
Any other ingredient, or the amount of sugar

Best before

What it tells you
The producer’s estimate of how long quality holds
What it does not
A safety limit; the use by date does that job

Spirit drink

What it tells you
A drink of at least 15% ABV that fits the definition but no named category
What it does not
The base, the age or the quality

Gin, vodka or rum in the name

What it tells you
All the alcohol comes from that spirit, if the name is a compound term
What it does not
How much of the spirit is in the can

Units, pregnancy logo, drinkaware.co.uk

What it tells you
Voluntary labelling guidance from the industry
What it does not
That the law requires them

No ingredients list

What it tells you
The exemption in Article 16(4) applies
What it does not
That anything is hidden

Premium, craft, bar-quality, hand-crafted

What it tells you
Nothing in Article 9(1) gives these a meaning
What it does not
Anything

Read the strength and the volume together, then count the units.

Annex XII sets the strength as a figure with at most one decimal place, then % vol., and the figure may be preceded by alcohol or alc. A label may also give % alc/vol. The figure is measured at 20°C, and most drinks above 1.2% ABV may differ from it by 0.3% vol either way.

The NHS’s sum turns the strength and the volume into units: ABV, multiplied by millilitres, divided by 1,000. A 250ml can at 5% ABV is 1.25 units. A 330ml can at 4% ABV is 1.3 units. A 500ml can at 7% ABV is 3.5 units.

Compare that with a bar serve. A Field Manual Gin and Tonic of 50ml of gin at 40% ABV is 2.0 units, and a 250ml can at 5% ABV is 1.25. The can is the lighter serve, but a large can at a higher strength can overtake it. ABV vs proof covers the scale, and the same label logic for spirits is in how to read a rum label and how to read a whisky label.

The NHS gives the Chief Medical Officers’ advice as no more than 14 units a week, taken regularly and spread over three or more days. A bottled cocktail at 20% ABV holds 14 units in 700ml, so one bottle is the whole week.

Read the allergen line, because it may be the only ingredient information.

Where there is no list of ingredients, Article 21(1) says the allergen appears as the word contains followed by its name from Annex II. The annex names cereals containing gluten, eggs, milk, nuts and sulphur dioxide and sulphites above 10mg a kilogram or litre, among others. Sulphites are worth looking for on a wine-based spritz, and milk on a cream serve.

Emphasis helps. For a food with a list, Article 21(1)(b) asks for the allergen to stand out by font, style or background colour. The Franklin & Sons product page for a bottled cola shows it in practice: the ingredients print BARLEY MALT extract in capitals and end with Contains gluten. Our own page for that cola records the gluten for the same reason.

A mixer bottle has an ingredients list, and Annex VII says quinine used as a flavouring is named in it. That is why tonic water names quinine. Article 16(4) lifts the list from a canned gin and tonic, so the quinine line need not appear.

Failing to give the allergen information is an offence under regulation 10 of the Food Information Regulations 2014, enforced by food authorities under regulation 9. The allergen line is the one piece of ingredient information a can cannot leave off.

Read the base: a named spirit, a spirit drink or a fermented base.

The base is the alcohol the drink was made from, and the label may name it in the drink’s name, in the sales name or not at all. A named spirit means the alcohol is that spirit. The words spirit drink mean the product is at least 15% ABV. Neither, and the producer’s own website is the next place to look.

The base matters for duty as well. GOV.UK’s rates, last updated on 1 February 2026, list spirit-based products apart from beer, cider, wine and other fermented products. From 3.5% to 8.4% ABV the spirits and wine rate is £26.61 a litre of pure alcohol, the beer rate is £22.58 a litre and the rate for cider other than sparkling cider is £10.39 a litre. A 250ml can at 5% ABV holds 12.5ml of pure alcohol, so the difference is a few pence of duty per can before VAT.

Read the date and the storage line last.

Annex X gives the wording: best before with the day, or best before end with the month, followed by any storage conditions. Beverages containing 10% or more by volume of alcohol need no date, so a stirred bottle at that strength may carry none. A can weaker than that should.

A best before date is about quality. Article 24 keeps the use by date for foods that turn dangerous after a short time, and a canned cocktail does not use it. Read the storage line for what to do after opening, because the label is the producer’s own statement and no table of keeping times applies to a whole class of product.

Units, pregnancy logos and responsibility messages are voluntary.

The labelling annex of the Portman Group’s Code lists four elements: unit content per container, a pregnancy logo or message, a pointer to drinkaware.co.uk, and the Chief Medical Officers’ guidelines. The annex says it is not part of the Code’s requirements and that failing to follow it is not a breach. Article 9(1) lists none of the four.

The Portman Group’s Code, which applies to any pre-packaged alcoholic drink above 0.5% ABV, also sets rules for a can’s design. Rule 3.1 says the alcoholic nature of a drink should be communicated with absolute clarity. Rule 3.2 says a drink should not give higher strength undue emphasis or have a particular appeal to under-18s.

A missing logo is therefore not a sign of anything. The units are in your hands: the sum above gives them from the two numbers Article 9(1) does list.

Words with no definition prove nothing.

Premium, craft, bar-quality and hand-crafted are not among the particulars Article 9(1) lists, and none of the legislation read here gives them a meaning. A can may use them without showing anything. A claim that carries weight gives you something to check, such as a strength to one decimal place, a named spirit or an allergen line.

The same holds for a missing ingredients list. Article 16(4) is the reason, not a sign that something is hidden. If you want a sugar figure or a full list, ask the producer or read its website. Nothing in the Article obliges it to publish one.

Frequently Asked Questions

What does alc vol mean on a can?

Alcohol by volume: the share of the drink that is pure alcohol. Annex XII of Regulation (EU) No 1169/2011 sets it as a figure with at most one decimal place, then % vol., measured at 20°C, and the figure may be preceded by alcohol or alc.

How many units are in a can of gin and tonic?

The NHS sum is ABV times millilitres, then divided by 1,000. A 250ml can at 5% ABV is 1.25 units, a 330ml can at 4% ABV is 1.3 units and a 500ml can at 7% ABV is 3.5 units.

Does a can of cocktail have sugar listed?

Not necessarily. Article 16(4) of Regulation (EU) No 1169/2011 makes the nutrition declaration and the ingredients list optional for drinks above 1.2% ABV. A producer can print a sugar figure, but Article 16(4) does not oblige it to.

Why do alcoholic drinks not list ingredients?

Article 16(4) of Regulation (EU) No 1169/2011 exempts beverages above 1.2% ABV from the list of ingredients and the nutrition declaration. It is an exemption, not a sign of concealment, and allergens must still be declared under Article 21.

What does contains mean on a can?

It is the allergen line. Where there is no ingredients list, Article 21(1) of Regulation (EU) No 1169/2011 says the allergen is shown as the word contains followed by its name from Annex II, such as milk, or sulphur dioxide and sulphites above 10mg a litre.

Does a can have to show units?

No. Article 9(1) of Regulation (EU) No 1169/2011 does not list them. The Portman Group’s labelling annex lists unit content per container as voluntary guidance. The NHS sum gives the units from the strength and the volume.

What does spirit drink mean on a bottled cocktail?

Under Regulation (EC) No 110/2008, spirit drink is the sales denomination for a drink of at least 15% ABV that fits the definition but no named category. It says nothing about the quality of the drink or what it is made from.

Does a canned cocktail need a best before date?

Below 10% ABV, yes, with any storage conditions. Annex X of Regulation (EU) No 1169/2011 leaves out beverages containing 10% or more by volume of alcohol, so a stirred bottle at that strength may have none.
