Who is ordering the drinks?

Organisers serving adult delegates

Choose clearly labelled individual cans so delegates can see what they are taking. Put water and caffeine-free soft drinks alongside the energy drinks.

Buyers adding a sugar-free choice

Keep the sugar-free cans identifiable at the drinks station, and compare their caffeine per whole can with the standard options. Sugar-free does not mean caffeine-free.

Organisers expecting under-16 attendees

Check the venue nation, attendees’ ages and the arrangements for serving or selling drinks. The UK Government announced in July 2026 a planned restriction on sales of qualifying high-caffeine drinks to under-16s in England from April 2027, subject to Parliamentary approval; that announcement does not establish a UK-wide rule.

What should you check before ordering?

Set the number of individual servings needed for each break, then compare the exact cans and multipacks you intend to order.

PriorityWhat to checkYour needs
Caffeine per can Read the caffeine declaration for the full can; if it is given per 100 ml, account for the can’s volume. Compare other caffeinated drinks offered at the event too. I want delegates to recognise the difference between a 250 ml and a 500 ml serving, rather than treating both cans as equivalent.
Sugar-free choice Check sugar and caffeine separately on each variant’s label. A zero-sugar name does not establish a lower caffeine amount. A separate sugar-free sparkling can would give attendees a choice beyond a sugared option.
Sparkling format Confirm carbonation for each selected variant, then check its flavour, sweeteners and can size. Do not assume every drink in a brand range has the same formula. I’m ordering fizzy energy drinks, so the precise variant matters more than a familiar brand name alone.
Multipack quantity Compare the number of cans, volume per can and total volume. Check the final stock position and supplied best-before dates before committing an event order. The cans need to cover the planned breaks without mistaking a larger pack volume for more individual servings.
Attendee information Keep caffeine warnings and ingredient labels accessible. The Food Standards Agency says food businesses must provide allergen information for prepacked and non-prepacked food and drink. Delegates should be able to identify what is in each drink, including when a caterer sets up the serving station.

Ordering mistakes to avoid

  • Assuming zero sugar means little caffeine

    Monster Ultra Zero Sugar’s product listing declares 30 mg caffeine per 100 ml in a 500 ml format. Its sugar-free name does not answer the whole-can caffeine question.

    Record sugar and caffeine as separate checks for every can you order, and keep non-caffeinated refreshments available.

  • Counting packs instead of servings

    Pack count and can size both affect how many individual drinks an order provides. A volume comparison alone does not tell you how many delegates can each take a can.

    Work out the required can count for the expected attendance and break schedule, then check the size and count of each proposed pack.

  • Relying on an old product page for the event order

    A product page does not establish that the exact variant and pack will be available for your event. Joybuy’s listing for Lucozade Alert Original 500 ml, for example, describes it as no longer available.

    Confirm the final SKU, stock, pack size and supplied best-before date before placing the order. Check any substitute’s own label.

  • Separating drinks from their labels

    Decanting cans can make their caffeine warnings and ingredient information harder for delegates to identify. The Food Standards Agency’s allergen-information requirements also apply to food businesses serving drinks.

    Where practical, serve labelled cans; otherwise, agree with the caterer how current product and allergen information will remain available at the serving point.

Brand and retailer references

These product lines and retail listings provide useful comparison points; a brand’s wider range should not be treated as one recipe or pack format.

Red Bull

A reference point for smaller individual cans.

  • Red Bull states that its Original 250 ml can contains 80 mg caffeine.
  • Check the sugar declaration on the exact variant supplied; Original and Sugarfree are different choices.

Monster

A range with larger cans and distinct standard and zero-sugar variants.

  • Monster Energy UK states that Original Green contains 160 mg caffeine in a 500 ml can.
  • A separate Monster Ultra Zero Sugar listing declares 30 mg caffeine per 100 ml; compare its full can rather than transferring Original Green’s figures to it.

Lucozade

Its Alert range is described by Lucozade as sparkling and high in caffeine.

  • The range offers a sparkling option to check when planning flavour variety.
  • Confirm the exact variant and current availability before including it in a catering order.

Relentless

A flavoured option for a drinks table with more than one energy-drink variant.

  • Relentless lists carbonated water and caffeine at 0.03% for its Guava variant.
  • Check the selected flavour’s own ingredients, caffeine declaration and pack size.

Tesco

A grocery retailer whose energy-drink listings can be used to identify pack formats.

  • Its category listing includes Red Bull Sugar Free 8 × 250 ml and Monster Energy Ultra 9 × 500 ml.
  • Check the current pack and stock details for the intended order.

Sainsbury's

A grocery retailer listing energy-drink multipacks across different brands.

  • Its category listing includes Monster Ultra Zero Sugar 9 × 500 ml and Red Bull 250 ml eight-packs.
  • Confirm the exact variant and pack details rather than assuming products from one brand are interchangeable.

Joybuy drink options

These Joybuy listings cover individual-can multipacks for a conference drinks table, including smaller and larger cans. Check each final label before treating a variant as sugar-free or using its caffeine figures.

CELSIUS Kiwi Guava 12 × 355 ml pack

CELSIUS Kiwi Guava 12 × 355 ml

The 12-can format provides individual 355 ml servings. Check the supplied cans for carbonation, sugar, caffeine and ingredient details before assigning this flavour a place on the drinks table.

Monster Energy Drink Original Green Zero Sugar 9 × 500 ml pack

Monster Energy Drink Original Green Zero Sugar 9 × 500 ml

This listing is for nine 500 ml cans. Its name says Zero Sugar, but the accompanying product information gives a sugar amount for a sugared drink; confirm the exact variant and its current label before choosing it for either a standard or a sugar-free place on the drinks table.

Red Bull Sugarfree Energy Drink 24 × 250 ml pack

Red Bull Sugarfree Energy Drink 24 × 250 ml

Monster Ultra White 12 × 500 ml pack

Monster Ultra White 12 × 500 ml

The 12-pack contains 500 ml cans. Joybuy describes this Ultra White variant as sparkling; check its own sugar and whole-can caffeine declarations when comparing it with smaller cans.

Red Bull Energy Drink 24 × 250 ml pack

Red Bull Energy Drink 24 × 250 ml

The 24-pack provides individual 250 ml cans for a standard energy-drink choice. Check the supplied label before recording an exact sugar figure for this SKU; the product information and Red Bull’s Original product information give different amounts.

Conference drinks questions

Should energy drinks be the only refreshments at a conference?

No. Offer them as an optional, labelled caffeinated drink alongside water and caffeine-free soft drinks. The European Food Safety Authority’s caffeine assessment concerns intake from all sources and does not address every attendee’s individual circumstances.

How do I compare 250 ml and 500 ml energy-drink cans?

Compare caffeine and sugar for the entire can. Red Bull states that its Original 250 ml can contains 80 mg caffeine, while Monster Energy UK states that its Original Green 500 ml can contains 160 mg; those figures refer to those specific variants, not every drink from either brand.

What if under-16s may attend the conference?

Check the venue nation, whether drinks will be sold or served, and the rules and event arrangements that apply at the time. In July 2026, the UK Government announced a planned restriction on sales of qualifying high-caffeine drinks to under-16s in England from April 2027, subject to Parliamentary approval; the announcement is not a rule for every UK venue.

What allergen information should the caterer have?

The Food Standards Agency says food businesses must provide allergen information for prepacked and non-prepacked food and drink. Ask for information covering each final drink variant, and keep the original can labels accessible where practical.
