Adults who prefer a smaller can
A 250ml can gives you a smaller individual serving than a 500ml can. Red Bull states that its Sugarfree 250ml can contains 80mg caffeine, so you can account for each can you open during the evening.
Who these multipacks suit
Adults who want a larger zero-sugar can
Monster’s 500ml zero-sugar range offers a larger format. Monster lists 150mg caffeine in Ultra and 160mg in Absolutely Zero per can; check which variant is in the multipack rather than treating the two as identical.
Adults stocking drinks for several viewers
Pack count and individual serving size both matter when more than one person may take a drink. Retailer listings include multipacks of 250ml cans, 500ml cans and 380ml bottles, so check the format as well as the number of containers.
What to check before choosing
Start with the drink you would actually want to open, then check its caffeine, sugar information and pack format against the other drinks planned for the evening.
| Priority | What to check | Your needs |
|---|---|---|
| Caffeine per can | Read the amount for the whole can, not just per 100ml. Red Bull lists 80mg per 250ml Sugarfree can; Monster lists 150mg per 500ml Ultra can and 160mg per 500ml Absolutely Zero can. Food Standards Scotland and the Food Standards Agency advise counting caffeine from other dietary sources too. | I want to know how much caffeine comes with each can I open, especially if I have also had coffee, tea or another caffeinated drink. |
| Sugar and drink type | Check the exact variant and its nutrition panel. Monster states 0g sugar per 500ml Ultra can, while the Lucozade Energy Original product listing gives 4.5g sugars per 100ml and lists glucose syrup. | A zero-sugar can may be what I want; alternatively, I might prefer Lucozade Energy Original’s glucose-based drink. I would compare those choices separately from their caffeine amounts. |
| Pack and serving size | Check both the container count and volume. Tesco has listed Red Bull Sugarfree 8 x 250ml and Lucozade Energy Original 8 x 380ml; Sainsbury’s has listed Monster 9 x 500ml multipacks. Confirm the current pack description and availability before ordering. | If several adults are sharing, I need enough individual drinks in a format they will want. For a smaller serving, the number of cans alone would not tell me enough. |
| Warnings and delivery | Read the product’s caffeine warning and the retailer’s delivery requirements. Sainsbury’s says it does not sell high-caffeine energy drinks to under-16s and may ask for proof of age on delivery. | I want to check that the drink and delivery arrangements are appropriate for the people involved, rather than assuming a snack order has no age checks. |
Common buying mistakes
-
Assuming zero sugar means little caffeine
Sugar and caffeine are separate label details. Monster states that Ultra contains 0g sugar and 150mg caffeine per 500ml can; its Absolutely Zero variant lists 0g sugar and 160mg caffeine per 500ml can.
Check caffeine for the exact variant and full can before choosing a multipack. If individual serving size matters, compare it with a smaller format such as Red Bull Sugarfree’s 250ml can, which Red Bull lists at 80mg caffeine.
-
Treating a glucose-based bottle like a zero-sugar can
The Lucozade Energy Original listing includes glucose syrup and gives 4.5g sugars per 100ml. That is a different sugar profile from the 0g sugar Monster states for Ultra.
Decide which drink type you want, then check its own serving size, sugar information and caffeine label rather than assuming the formats are interchangeable.
-
Overlooking caffeine warnings and age checks
Other caffeinated drinks consumed during the day add to the amount from an energy-drink can. Delivery may also involve an age check: Sainsbury’s says it may request proof of age for high-caffeine energy drinks.
Read the warning on the product you select, account for other caffeine and check the retailer’s delivery requirements before ordering for a group.

Questions about caffeine and age checks
How should I count caffeine when choosing drinks for an evening in?
Count the caffeine in each energy-drink serving alongside coffee, tea and other caffeinated products consumed that day. For comparison, Red Bull states 80mg per 250ml Sugarfree can and Monster states 150mg per 500ml Ultra can. Food Standards Scotland and the Food Standards Agency advise considering caffeine from all dietary sources.
Does zero sugar mean an energy drink has little caffeine?
No. Monster lists 0g sugar alongside 150mg caffeine per 500ml Ultra can, and 0g sugar alongside 160mg caffeine per 500ml Absolutely Zero can. Check sugar and caffeine separately for the exact variant.
Could an energy-drink delivery require proof of age?
Yes. Sainsbury’s says it does not sell high-caffeine energy drinks to under-16s and may ask for proof of age on delivery. Check the requirements of the retailer handling your order.
