Hosts planning an adult board game night
Compare the number of separate cans with the number of people likely to want one. Check can volume and caffeine per can too: a pack count alone does not tell you the size of each serving.
Who is choosing the drinks?
Buyers looking for zero sugar
Choose by the declaration for the exact drink, then check caffeine separately. Tesco lists Monster Zero Sugar at 0g sugars and 180mg caffeine per 500ml can.
Hosts with mixed-age or caffeine-sensitive guests
Have water and non-caffeinated drinks alongside any energy drinks. The cited Monster Zero Sugar and Relentless Origin labels advise against use by children, pregnant or breastfeeding women, and people sensitive to caffeine.
What should you check?
Start with who will drink the cans, then compare the portion, caffeine and sugar declaration for the exact multipack.
| Priority | What to check | Your needs |
|---|---|---|
| Caffeine per can | Compare the declared amount for the full can, not just per 100ml. Red Bull UK states 80mg per 250ml can of its Energy Drink; Tesco lists 180mg per 500ml can of Monster Zero Sugar. Count caffeine from other drinks separately. | I want guests to know how much caffeine is in the can they open, especially if both 250ml and 500ml options are on the table. |
| Sugar choice | Check sugars for the exact variant and serving size. A zero-sugar label does not establish a lower caffeine amount; Tesco lists its Monster Zero Sugar product at 0g sugars but 180mg caffeine per 500ml can. | If I want a zero-sugar option, I need that declaration on the product itself rather than assuming every drink from a brand has the same formulation. |
| Can and pack size | Read both the can count and volume. Tesco lists Red Bull Energy Drink as 12 × 250ml, while Sainsbury’s lists Relentless Origin as 4 × 500ml. Decide how many adults are likely to take a can. | For a group, I want enough separate cans without offering a 500ml serving to someone who expected a smaller one. |
| Guest suitability | Read the warning on the exact can. The cited Tesco Monster Zero Sugar and Sainsbury’s Relentless Origin listings advise against use by children, pregnant or breastfeeding women, and people sensitive to caffeine. | Not everyone at the table will want or be suited to a high-caffeine drink, so I want non-caffeinated choices ready as well. |
Common buying mistakes
-
Treating every can as the same serving
Can count hides substantial differences in volume and caffeine. Red Bull UK states 80mg caffeine per 250ml Energy Drink can, while Tesco lists 180mg in a 500ml Monster Zero Sugar can.
Compare caffeine for the full can and its volume before deciding how many cans to bring.
-
Using zero sugar as a caffeine check
Tesco’s Monster Zero Sugar listing declares 0g sugars and 180mg caffeine per 500ml can. Those are separate product attributes.
Use the sugar declaration to choose a formulation, then read the caffeine amount for that exact can.
-
Assuming an energy drink suits every guest
The cited Monster Zero Sugar and Relentless Origin labels caution against use by children, pregnant or breastfeeding women, and people sensitive to caffeine.
Ask what guests would like to drink and put water and non-caffeinated options within reach.
Relevant brand ranges
A brand name is only a starting point: pack formats and declarations differ between products and variants.
Red Bull
A reference point for smaller cans: Tesco lists Red Bull Energy Drink in a 12 × 250ml pack.
- Red Bull UK states 80mg caffeine per 250ml can of its Energy Drink.
- It is a sugar-containing formulation. Red Bull UK states 27g sugars per 250ml can; check the label of the pack you buy for its exact declaration.
Monster Energy
Its cited UK products include different 500ml formulations, so compare variants rather than relying on the brand name.
- Tesco lists a Monster Zero Sugar 4 × 500ml pack with 0g sugars per can.
- That Tesco Zero Sugar listing states 180mg caffeine per can. Separately, Monster Energy UK states 160mg caffeine and 55g sugar for its Original Green 500ml can; those figures do not describe every Monster drink.
Relentless
Relentless Origin appears in the cited UK listings as both a 4 × 500ml and a 12 × 500ml pack.
- Sainsbury’s lists 32mg caffeine and 3.7g sugars per 100ml for its Origin 4-pack.
- The Sainsbury’s listing carries a high-caffeine warning and advises against use by children, pregnant or breastfeeding women, and people sensitive to caffeine.
Lucozade Alert
Lucozade describes Alert as a high-caffeine range, distinct from choosing a drink solely by the broader Lucozade name.
- For a multipack comparison, read the caffeine, sugar, can size and warning on the exact Alert product before choosing it.
Joybuy multipack options
These Joybuy options include smaller 250ml cans and larger 500ml cans, with regular-sugar and sugar-free variants. Choose the format for the adults who want it, then check the exact can label before serving.

Red Bull Energy Drink 12 × 250ml
Twelve smaller individual cans for adults who prefer a 250ml serving. Red Bull UK states 80mg caffeine per can of this drink. It contains sugar; check the pack label for the exact sugar declaration.
No image available
Monster Energy Original Green 9 × 500ml
Nine larger cans for adults who deliberately want a 500ml serving. Monster Energy UK states 160mg caffeine and 55g sugar per 500ml Original Green can; check that this is the variant you intend to serve.
No image available
Rockstar Blueberry & Pomegranate 12 × 500ml
A 12-can option for adults choosing the larger 500ml format. Check the can’s caffeine and sugar declarations and its suitability warning before offering it to guests.
No image available
Monster Energy Ultra Zero Sugar 4 × 500ml
Four larger cans for a group choosing a zero-sugar variant. Check caffeine on the Ultra can itself; the caffeine figure for a different Monster Zero Sugar product should not be used for this one.
No image available
Red Bull Sugarfree Energy Drink 12 × 250ml
Twelve smaller cans for adults who want a sugar-free formulation. Read the Sugarfree can’s own caffeine declaration rather than applying a figure from Red Bull Energy Drink.
Questions about energy drink multipacks
Does zero sugar mean less caffeine?
No. Tesco lists its Monster Zero Sugar 4 × 500ml product at 0g sugars but 180mg caffeine per can. Compare the sugar and caffeine declarations separately for the exact variant you plan to buy.
Should I compare caffeine per 100ml or per can?
Use the full can for a serving comparison. If a label gives caffeine per 100ml, account for the can’s volume; a 500ml can contains five 100ml portions. Other caffeinated drinks consumed that day matter too.
What if children will be at the game night?
Provide non-caffeinated drinks rather than assuming an energy drink is suitable. The cited Monster Zero Sugar and Relentless Origin labels advise against use by children. For sales in England, the Department of Health and Social Care and Department for Education have announced a ban on high-caffeine energy drinks for under-16s intended to start in April 2027, subject to Parliamentary approval; check the position applicable at purchase time.
What matters most when ordering a multipack?
Confirm the can count, volume, exact variant, caffeine and sugar declarations, and label warnings. A 12 × 250ml pack and a 4 × 500ml pack offer different numbers and sizes of individual servings, even though both are multipacks.
