Adults-only party hosts
If adult guests have chosen energy drinks, compare the amount in each can as well as the number of cans in the pack. Decide whether regular or sugar-free variants suit the drinks you plan to offer.
Who is choosing the drinks?
Hosts of mixed-age parties
Keep caffeine-free drinks available as the general option when under-16s may attend. In England, the Department of Health and Social Care and Department for Education say a ban on sales of high-caffeine energy drinks to under-16s is scheduled from April 2027; Sainsbury’s already applies its own under-16 sales policy.
Adult hosts looking for sugar-free cans
A sugar-free multipack offers a different sugar choice, but it can still contain caffeine. Check the exact variant’s ingredients and caffeine statement before deciding what to serve.
What should you check?
Start with who will be offered a can, then compare the serving size and label of the exact multipack.
| Priority | What to check | Your needs |
|---|---|---|
| Guest age | Check who will be offered energy drinks and any delivery age checks. The England sales restriction announced by the Department of Health and Social Care and Department for Education is scheduled for April 2027 and covers drinks other than tea or coffee with more than 150mg caffeine per litre. | If children are coming, I want caffeine-free drinks to be the general party option. Sainsbury’s says it already does not sell high-caffeine energy drinks to under-16s. |
| Caffeine per can | Read the caffeine amount for the whole can, not just per 100ml, and compare the exact variants. Red Bull states 80mg in a regular 250ml can; Monster states 160mg in a 500ml Original Green can. | For adult guests, I want to know what one can contains before deciding how many cans to put out. |
| Sugar and ingredients | Check the sugar line, caffeine statement and sweeteners on each variant. Red Bull states 27g sugars in its regular 250ml can; Monster states 55g in a 500ml Original Green can. Sugar-free does not mean caffeine-free. | I would like to offer adults a sugar-free choice without presenting it as a drink without caffeine. |
| Pack format | Compare both can volume and can count. Tesco and Sainsbury’s list formats including 250ml, 380ml and 500ml cans in multipacks; check the precise format when ordering. | I need enough cans for the adults choosing them, rather than treating every party guest or every can size as interchangeable. |
Common buying mistakes
-
Counting cans without checking their size
One can is not a consistent caffeine serving: Red Bull states 80mg for its regular 250ml can, while Monster states 160mg for Original Green in a 500ml can.
For an adults-only party, read caffeine per whole can before choosing the pack count.
-
Treating sugar-free as caffeine-free
Joybuy’s Red Bull Sugar Free listing states that it contains caffeine, while its Monster Ultra Zero Sugar listing states 30mg caffeine per 100ml.
Check the exact can’s caffeine, sweeteners and warnings when choosing a sugar-free option for adults.
-
Putting energy drinks out as general refreshments
Age matters at a mixed-age party. Sainsbury’s applies an under-16 sales policy to high-caffeine energy drinks, and Joybuy’s listed Red Bull multipacks display an age-verification notice for delivery.
Plan caffeine-free drinks for children and check delivery requirements before ordering energy drinks for adult guests.
Brand and format references
Red Bull
Tesco and Sainsbury’s list Red Bull 250ml multipacks, including regular and sugar-free variants.
- Red Bull states that its regular 250ml can contains 80mg caffeine and 27g sugars.
- Check the variant: sugar-free Red Bull still contains caffeine, and ingredients can differ from the regular drink.
Monster Energy
Tesco and Sainsbury’s list Monster multipacks with 500ml cans, including Original and zero-sugar variants.
- Monster states that a 500ml Original Green can contains 160mg caffeine and 55g sugar.
- Zero-sugar variants still need a separate caffeine check; the amount stated for Original Green does not describe every Monster can.
Lucozade Energy
UK retailer listings include Lucozade Energy multipacks with 380ml and 330ml cans.
- These formats give hosts another can size to consider when counting adult servings.
- Check caffeine and nutrition on the exact variant’s can before comparing it with a 250ml or 500ml option.
Relentless
Tesco and Sainsbury’s list Relentless Origin in a 4x500ml format.
- The listed format combines four individual 500ml cans.
- Check the exact can label for caffeine and nutrition rather than assuming it matches another 500ml drink.

Questions about party drinks
Should I buy energy drinks for a child’s birthday party?
Choose caffeine-free drinks as the general party refreshments. For England, the Department of Health and Social Care and Department for Education say sales of drinks other than tea or coffee containing more than 150mg caffeine per litre to under-16s are scheduled to be banned from April 2027. Sainsbury’s already says it does not sell high-caffeine energy drinks to under-16s.
How do I compare caffeine in 250ml and 500ml cans?
Compare the amount per whole can for the exact drinks you are considering. Red Bull states 80mg caffeine in its regular 250ml can, while Monster states 160mg in a 500ml Original Green can; those figures should not be assumed for other variants.
Does sugar-free mean caffeine-free?
No. Joybuy’s Red Bull Sugar Free listing identifies caffeine, and its Monster Ultra Zero Sugar listing states 30mg caffeine per 100ml. Read both the sugar and caffeine information on the exact can.
How many multipacks should I buy?
Start with the adults who want an energy drink, then choose a can size and count the individual cans needed. Keep caffeine-free options available for other guests, and make any difference between 250ml and 500ml cans clear if you offer both.
Could delivery involve an age check?
Yes. Sainsbury’s says products marked as not recommended for children are subject to age verification, and Joybuy’s listed Red Bull multipacks display an age-verification notice for delivery. Check the requirements shown for your order before arranging delivery.
