What should you check before buying?
Start with the container you intend to serve, then compare the caffeine and sugar information for that exact drink rather than treating every can or bottle in a multipack as interchangeable.
| Priority | What to check | Your needs |
| Container size |
Check the listed volume of each bottle or can and distinguish a multipack’s combined volume from a single 2-litre bottle. Tesco Groceries and Sainsbury’s Groceries list individual cans and multipacks; Sainsbury’s also lists a 900ml Lucozade Energy bottle. |
I need to know whether guests will take separate drinks or pour from one bottle. If one 2-litre container is essential, I will check the exact product listing before planning around it. |
| Caffeine |
Read the caffeine amount and the volume it refers to on the exact variant. Monster Energy UK states 160mg per 500ml can for Original Green and Zero Sugar; Red Bull UK states 80mg per standard 250ml can. |
For an adult gathering, I want to identify what is in each container before offering it, rather than assuming a smaller or sugar-free drink contains less caffeine. |
| Sugar |
Compare sugar on the same per-container or per-100ml basis and check the variant name. Monster Energy UK states 55g per 500ml Original Green can and 0g per 500ml Zero Sugar can; both state 160mg caffeine. |
Sugar content matters to my choice, but I will check caffeine separately instead of using a zero-sugar label as a shortcut. |
| Guest access |
Check the pack warning. GOV.UK says drinks above 150mg caffeine per litre must warn that they are not suitable for children, pregnant women or people sensitive to caffeine. |
When guests of different ages share a drinks table, I want to keep energy drinks separate from drinks offered to everyone. |
Which brands offer relevant formats?
These brand examples help distinguish a bottle from individual cans; a brand’s other products may have different sizes and labels.
Lucozade Energy
Sainsbury’s Groceries lists a 900ml Original bottle, a single-container option for hosts who prefer to pour drinks.
- The listed 900ml bottle provides a format distinct from an individual can.
- 900ml is not the requested 2 litres; check the exact bottle label when planning servings.
Monster Energy
Tesco Groceries and Sainsbury’s Groceries list 500ml-can multipacks, including sugar-free variants.
- Monster Energy UK gives separate caffeine and sugar figures for its Original Green and Zero Sugar 500ml cans.
- Both variants state 160mg caffeine per 500ml can, so Zero Sugar is not a lower-caffeine choice on those figures.
Red Bull
The Tesco Groceries and Sainsbury’s Groceries listings include multipacks of 250ml cans.
- Red Bull UK states 80mg caffeine per standard 250ml can, making the stated amount for that product identifiable by can.
- A multipack supplies separate cans, not a 2-litre bottle; check other variants on their own labels.
Relentless
Tesco Groceries lists a 500ml Origin can, and Sainsbury’s Groceries lists an Origin 4 × 500ml multipack.
- The listed single-can and multipack formats give hosts separate-container options.
- Check the caffeine, sugar and ingredients on the exact Origin pack before comparing it with another drink.

Red Bull Sugarfree Energy Drink 12 × 250ml
This pack provides twelve separate 250ml cans rather than one bottle. If choosing it for the Sugarfree variant, check its own caffeine declaration as well as its sugar information; the standard Red Bull figure does not establish the amount in this variant.

Questions about size, labels and age
Do Tesco or Sainsbury’s list a 2-litre energy-drink bottle?
The Tesco Groceries and Sainsbury’s Groceries listings cited here show smaller energy-drink formats, including a 900ml Lucozade Energy bottle, rather than a confirmed 2-litre product. Check a current product page if a single 2-litre bottle is essential; those listings do not establish what every retailer sells.
Does sugar-free mean less caffeine?
No. Monster Energy UK states that both Original Green and Zero Sugar contain 160mg caffeine per 500ml can, while listing 55g sugar for Original Green and 0g for Zero Sugar. Compare the declarations for the exact variants you are considering.
Which warning should I check on an energy drink?
GOV.UK says drinks containing more than 150mg caffeine per litre must warn that they are not suitable for children, pregnant women or people sensitive to caffeine. Read the warning and caffeine declaration on the exact pack you plan to serve.
Can an under-16 buy a high-caffeine energy drink?
The answer depends on where and when the drink is bought, as well as the retailer’s policy. The Department of Health and Social Care announced an England-only ban on sales to under-16s starting in April 2027; do not treat that announcement as a UK-wide rule or as a ban already in force for this Bonfire Night.
