Organisers serving a mixed adult group
Individually portioned cans make it easier to offer a choice of formats. Keep energy drinks optional and include non-caffeinated refreshments for people who do not want caffeine.
Who is choosing the drinks?
Teams looking for a sugar-free option
Compare caffeine and can size as well as sugars. Monster Energy UK lists 0 g sugar but 160 mg caffeine in its Absolutely Zero 500 ml can, so sugar-free does not mean caffeine-free.
Organisers considering 500 ml cans
Check whether attendees actually want a larger serving. Monster Energy UK lists 160 mg caffeine in each of its Original Green and Absolutely Zero 500 ml cans; its Original Green can also lists 55 g sugars.
What should you check before ordering?
Start with the serving you intend to offer each person, then check the exact variant’s label and the number of cans needed. Sugar-free is a separate choice from can size and caffeine content.
| Priority | What to check | Your needs |
|---|---|---|
| Caffeine per can | Read the amount for one can of the exact variant, not just the concentration per 100 ml. Red Bull states 80 mg per 250 ml Original can; Monster Energy UK lists 160 mg per 500 ml Original Green or Absolutely Zero can. | I want attendees to be able to judge a can alongside coffee, tea or other caffeine they may already have had. |
| Sugars | Compare the nutrition information for the exact flavour and can size. Red Bull states 27 g sugars in its Original 250 ml can; Monster Energy UK lists 55 g in Original Green and 0 g in Absolutely Zero, each per 500 ml can. | A no-sugar choice matters to some attendees, but I do not want to mistake it for a lower-caffeine choice. |
| Can and pack size | Check both millilitres per can and cans per pack. Tesco Groceries lists examples including Red Bull 4 × 250 ml and 8 × 250 ml packs, and Monster Ultra 4 × 500 ml and 9 × 500 ml packs. | Smaller individual servings may suit our meeting better than putting out a large can for everyone. I also want a pack count that fits expected use. |
| Attendee suitability | Read the exact product’s caffeine warning and keep a non-caffeinated option available. Joybuy’s Red Bull Sugar Free listing warns against use by children and pregnant or breastfeeding women; Relentless gives a warning for caffeine-sensitive people on its Guava product. | Not everyone at the meeting will want caffeine, so I need refreshments that do not depend on an energy drink being suitable for all. |
Common buying mistakes
-
Comparing packs by can count alone
Eight 250 ml cans and nine 500 ml cans provide different individual servings. Red Bull states 80 mg caffeine per Original 250 ml can, while Monster Energy UK lists 160 mg per Original Green or Absolutely Zero 500 ml can.
Estimate how many cans the adult group is likely to use, then compare the volume and caffeine for each can.
-
Assuming sugar-free also means less caffeine
Monster Energy UK lists 0 g sugar and 160 mg caffeine in its Absolutely Zero 500 ml can. The sugar figure alone cannot tell you how much caffeine a serving contains.
Check sugars, caffeine and can size together on the variant you intend to order.
-
Putting out energy drinks as the only choice
Warnings on the reviewed Red Bull Sugar Free and Relentless Guava products identify groups for whom those drinks are not recommended, including children and pregnant or breastfeeding people; the Relentless warning also names people sensitive to caffeine.
Make energy drinks optional, leave their labels visible and provide water or another non-caffeinated drink.
Brand and product-line references
A brand name does not establish the can size, sugars or caffeine of every variant. Use these examples to identify what to check on the particular multipack.
Red Bull
Its 250 ml Original and Sugar Free cans offer compact formats to compare for an adult meeting.
- Red Bull states that an Original 250 ml can contains 80 mg caffeine and 27 g sugars. Joybuy lists a Sugar Free 8 × 250 ml pack with 0 g sugars per 100 ml.
- Original is not sugar-free. Check the warning and nutrition information for the exact variant rather than applying Original’s figures to Sugar Free.
Monster Energy
The reviewed Original Green and Absolutely Zero products are 500 ml cans, a larger serving than the reviewed 250 ml Red Bull cans.
- Monster Energy UK lists 160 mg caffeine per 500 ml can for both products, with 55 g sugars for Original Green and 0 g for Absolutely Zero.
- These figures belong to those named variants; do not assume another Monster flavour or multipack has the same caffeine or nutrition information.
Relentless
Consider the exact flavour and label when comparing it with other energy drinks for attendees.
- The Relentless Guava ingredient list states caffeine at 0.03%.
- Its Guava warning says the drink is not recommended for children, caffeine-sensitive people, pregnant women or women who are nursing. Check the chosen pack for its own serving and caffeine information.
Lucozade
Check the particular Lucozade range and product rather than treating every drink under the brand as interchangeable.
- Lucozade describes its Lucozade Energy range as containing glucose.
- Use the exact can’s nutrition and caffeine information when comparing it with a conventional energy-drink multipack.

CELSIUS Kiwi Guava 12 × 355 ml
For a meeting where adults want individually portioned cans larger than 250 ml, this Kiwi Guava pack contains twelve 355 ml cans. Check the exact can’s sugars, caffeine and warnings before putting it out for attendees.
No image available
Red Bull Energy Drink 8 × 250 ml
This Original eight-pack offers smaller individual cans when adults specifically want the sugared version. Red Bull states 80 mg caffeine per Original 250 ml can; check the current pack label for its sugars before choosing between Original and Sugar Free.
No image available
MONSTER ENERGY Ultra Zero Sugar 4 × 500 ml
Consider this four-pack when adults specifically want a larger, zero-sugar can rather than a 250 ml serving. Check caffeine per can and the warnings on this Ultra variant’s label; figures for Monster’s Absolutely Zero variant should not be applied to it.
Questions about meeting refreshments
How should I compare caffeine amounts for a meeting?
Compare milligrams per can for each exact product and remember that coffee, tea and other drinks also contribute caffeine. The European Food Safety Authority’s assessment discusses single doses up to 200 mg and daily intake up to 400 mg from all sources for adults in the general population, excluding pregnant women; these assessment figures are not suggested amounts to serve.
Should 500 ml cans be the default for a mixed group?
A smaller can is the more restrained serving-size choice unless adults specifically want 500 ml. Monster Energy UK lists 160 mg caffeine in each of its Original Green and Absolutely Zero 500 ml cans, while Red Bull states 80 mg in an Original 250 ml can; check the exact variants rather than assuming size alone determines caffeine.
Does sugar-free mean an energy drink has less caffeine?
No: Monster Energy UK lists 0 g sugar but 160 mg caffeine in its Absolutely Zero 500 ml can. Compare the sugar and caffeine information for the same variant and can size.
Should energy drinks be the only meeting refreshments?
No. Provide water and non-caffeinated choices, and check each energy drink’s warning before offering it; the reviewed Red Bull Sugar Free and Relentless Guava warnings identify people for whom those products are not recommended.
Is an under-16 energy-drink sales ban in force across the UK?
The Department of Health and Social Care and Department for Education announced in July 2026 a planned England retail-sales ban from April 2027, subject to the legislation process; it is not a confirmed UK-wide rule. The announcement covers drinks other than tea or coffee containing more than 150 mg caffeine per litre and excludes business-to-business sales. Check the applicable rules if a purchase involves minors.
