Occasional second-home hosts
If visits are spaced apart, compare the number of cans with planned stays and check the on-pack best-before date. Single-serve cans let visitors choose a drink without opening a larger container.
Who is this choice for?
Adults choosing zero sugar
Check the claim and ingredients on the exact flavour. Sugar content and caffeine content are separate: a zero-sugar energy drink can still contain caffeine.
Households with different serving preferences
A smaller can and a larger can offer different amounts per container. Red Bull states 80 mg caffeine per 250 ml Sugarfree can; Monster Energy states 150 mg per 500 ml Ultra can. Visitors can compare those amounts with other caffeine they plan to consume.
What should you check before stocking up?
Smaller zero-sugar cans
Choose when: Visitors prefer a 250 ml serving; Red Bull states that a Sugarfree can contains 80 mg caffeine.
Bear in mind: A smaller can still adds to caffeine consumed from other drinks.
Larger zero-sugar cans
Choose when: An adult wants a 500 ml serving and has checked its caffeine amount; Monster Energy states 150 mg per Ultra can.
Bear in mind: That Ultra serving contains more caffeine per can than the stated 250 ml Red Bull Sugarfree serving.
Zero-sugar soft drinks
Choose when: The priority is a sparkling soft-drink format rather than a particular energy-drink serving; Lucozade describes its Zero range as sugar free.
Bear in mind: Check the exact product’s label rather than assuming its caffeine content matches a canned energy drink.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar and ingredients | Confirm the zero-sugar or sugar-free claim on the exact flavour and pack. Read the ingredient list if particular sweeteners matter to you. | I want to stock drinks without sugar, but I do not want to pick up a different variant because its packaging looks similar. |
| Caffeine per container | Compare milligrams per full can, not just can size or sugar content. Include caffeine from other drinks when considering a day’s consumption. | A smaller caffeine amount per can matters when visitors may also have coffee, tea or other caffeinated drinks. |
| Pack quantity and date | Count the containers against expected visits and check the best-before date on the pack. Compare the date for the pack you will actually buy. | For infrequent stays, I would rather stock a quantity likely to be used during planned visits. |
| Drink format | Decide whether visitors want a canned energy drink or a sparkling zero-sugar soft drink. Check the caffeine declaration for the exact product. | Some visitors may want a zero-sugar soft drink without choosing by an energy drink’s stated caffeine amount. |
Common stocking mistakes
-
Reading ‘zero sugar’ as ‘little caffeine’
Sugar and caffeine are separate product attributes. Monster Energy states that a 500 ml Ultra can contains zero sugar and 150 mg caffeine.
Compare caffeine per full container on the exact drink and consider other caffeinated drinks that day.
-
Buying a case without checking planned visits
Stock at a home used only occasionally may remain unopened for longer than expected.
Check the on-pack best-before date and choose a pack quantity that fits the visits you have planned.
-
Treating different can sizes as the same serving
Red Bull states 80 mg caffeine per 250 ml Sugarfree can, while Monster Energy states 150 mg per 500 ml Ultra can. The caffeine amount per full container differs as well as the volume.
Choose the can size deliberately, then check the caffeine information on the exact variant you buy.

Questions about zero-sugar drinks and storage
Does zero sugar mean little or no caffeine?
No. Sugar and caffeine are separate attributes. Monster Energy states that its 500 ml Ultra can has zero sugar and 150 mg caffeine; Red Bull states 80 mg caffeine in a 250 ml Sugarfree can. Compare the exact drink’s label and container size.
What should I check before leaving drinks at a second home?
Check the best-before date against planned visits, along with the pack quantity, ingredients and caffeine information for each chosen drink. UK food-labelling guidance from the Department for Environment, Food & Rural Affairs and the Food Standards Agency identifies dates, ingredients and net quantity among the information required on pre-packed food.
Is an under-16 energy-drink sales ban in force across the UK?
Do not treat an England announcement as a UK-wide rule. On 16 July 2026, the Department of Health and Social Care announced an intended ban on sales of high-caffeine energy drinks to under-16s in England from April 2027, subject to Parliamentary approval. Check the applicable rules before supplying drinks to minors.
