Shoppers wanting a smaller can
A 250ml multipack provides separately portioned cans for planned afternoon occasions. Can size does not settle the caffeine question, so read the warning and consider when you expect to sleep.
Who might choose each format?
Shoppers comparing sugar-free recipes
Compare sugars on the nutrition panel for the exact can size, then check caffeine separately. Sugar-free examples listed by Tesco and Sainsbury’s still contain caffeine.
Households planning several occasions
Check both the number of cans and the volume of each one against how the household intends to use the pack. Read product warnings and the retailer’s age policy where children might have access to the drinks.
What should you check before buying?
Start with the serving you actually want, then compare the recipe and warnings on that specific pack. A multipack count alone does not tell you how much is in each can.
| Priority | What to check | Your needs |
|---|---|---|
| Can size | Read the volume per can and the number of cans. Decide whether a 250ml or 500ml drink matches the occasion. | I would rather open a smaller can for one afternoon break than commit to a larger drink. |
| Sugars | Compare sugars per 100ml and per can where listed. Check the ingredients if you have a preference about sweeteners. | The recipe matters to me as much as the flavour: I want to distinguish a sugar-containing drink from a no-sugar one. |
| Caffeine and timing | Read the caffeine statement on the exact pack; do not use a sugar-free label as a caffeine check. Consider when you plan to drink it. | If bedtime is approaching, I need to decide whether a caffeinated drink belongs in my afternoon routine. Royal Papworth Hospital NHS Foundation Trust advises avoiding caffeinated drinks in the afternoon and evening in its sleep guidance. |
| Household access | Read the high-caffeine warning and check the retailer’s age-verification policy before ordering for a shared household. | I want to know who may access the multipack. Sainsbury’s states that it does not sell high-caffeine energy drinks to under-16s. |
Common buying mistakes
-
Choosing a pack without checking the can size
Four 500ml cans and several 250ml cans serve different plans, even though both are multipacks.
Choose the volume you intend to drink on one occasion before comparing pack counts.
-
Reading “zero sugar” as “caffeine-free”
Tesco’s Red Bull Sugar Free listing and Sainsbury’s Blue Bolt Zero listing both state that the drinks contain caffeine.
Check the sugars line and the caffeine information separately. If you want to avoid caffeine, choose a non-caffeinated drink rather than relying on a sugar-free label.
-
Overlooking who can access the multipack
A pack stored for several occasions may also be accessible to children. High-caffeine product warnings and retailer age policies matter when buying for a household.
Read the exact pack warning and check the retailer’s current age-verification policy before checkout.
-
Making caffeine the default afternoon choice
An afternoon drink may be too close to bedtime for someone concerned about sleep. Royal Papworth Hospital NHS Foundation Trust advises avoiding caffeinated drinks in the afternoon and evening.
If that timing is a concern, consider a non-caffeinated drink alongside your snack instead.
Brand and retailer references
These examples show why the exact pack and recipe matter; a brand name alone does not establish can size, sugars or caffeine content.
Red Bull
Tesco lists original and Sugar Free Red Bull multipacks in 12 x 250ml formats.
- The defined 250ml can size makes pack formats straightforward to compare.
- Tesco lists 11g sugars per 100ml for the original recipe and 0g per 100ml for Sugar Free; both listings state caffeine at 0.03%.
Monster Energy
Sainsbury’s lists Monster Energy Drink Ultra in a 4 x 500ml multipack.
- The 500ml can is a distinct option for someone deliberately choosing a larger drink.
- Check the warning and nutrition panel for the exact Monster variant rather than applying one recipe’s details to another.
Relentless
Sainsbury’s lists Relentless Origin as a 4 x 500ml can pack.
- The pack provides four separately canned 500ml drinks.
- A 500ml can may not fit a plan for a smaller afternoon portion; read the caffeine statement before choosing it.
Lucozade Energy
Sainsbury’s lists Lucozade Energy multipacks in several can sizes, including 380ml and 330ml formats.
- These formats offer a can size between the 250ml and 500ml examples.
- Check the exact variant’s nutrition and caffeine information before comparing it with another drink.
Sainsbury’s Blue Bolt
Sainsbury’s lists Blue Bolt and Blue Bolt Zero in 6 x 250ml packs.
- Its listings give per-can figures: Blue Bolt Zero has fewer than 0.5g sugars, while standard Blue Bolt has 11.1g.
- Both listed recipes state caffeine at 0.03%, so choosing Zero does not remove caffeine.
Tesco
Tesco is a retailer reference here: its Red Bull listings provide pack sizes, ingredients and nutrition for the named recipes.
- Its 12 x 250ml original and Sugar Free listings allow recipe details to be checked for the same can size.
- Check the product page for the particular pack you intend to buy rather than assuming its details apply to other variants.

Nine 500ml cans suit a plan for larger drinks across multiple occasions, not a search for a small single can. This is the original sugar-containing variant; compare its nutrition panel and caffeine warning with the alternatives.
Frequently asked questions
Is a sugar-free energy drink caffeine-free?
No. Tesco’s Red Bull Sugar Free listing and Sainsbury’s Blue Bolt Zero listing both state caffeine at 0.03%. Check caffeine information separately from the sugars line on the exact pack.
Should I choose 250ml or 500ml cans for an afternoon snack?
Choose 250ml if you want a smaller, separately portioned drink; consider 500ml if you intend to drink a larger can. In either case, read that product’s nutrition panel and caffeine warning rather than treating can size as a complete guide to its contents.
Could an afternoon energy drink affect sleep?
Caffeine timing matters if sleep is a concern. Royal Papworth Hospital NHS Foundation Trust advises avoiding caffeinated drinks in the afternoon and evening in its sleep guidance; a non-caffeinated drink is an alternative when bedtime is approaching.
What should I check when buying for a household with children?
Read the exact product warning and the retailer’s current age policy. Sainsbury’s states that it does not sell high-caffeine energy drinks to under-16s; that retailer policy should not be treated as a statement of the law across the UK.
What if someone is pregnant or breastfeeding?
Check the warning on the exact drink rather than assuming all recipes carry identical wording. Joybuy’s Red Bull Sugar Free 8 x 250ml listing states that the high-caffeine drink is not recommended for pregnant or breastfeeding women.
