Hosts buying for several adults
If you want around 2 litres of energy drink, Tesco lists four 500ml cans and eight 250ml Red Bull cans as different ways to reach that total. Neither pack is one sharing bottle.
Who is this for?
Shoppers comparing sugar options
A zero-sugar label does not mean a drink has no caffeine. Monster Energy states that a 500ml Monster Ultra can contains 0g sugar and 150mg caffeine; check the exact can when choosing a pack.
Hosts planning a mixed-age gathering in England
Keep the drinks for adult guests distinct from refreshments for children. The Department of Health and Social Care has announced an England sales restriction for qualifying high-caffeine drinks and under-16s from April 2027, subject to Parliamentary approval.
What should you check?
Decide whether you need one bottle or separate servings, then compare the volume and label of the exact pack.
| Priority | What to check | Your needs |
|---|---|---|
| Total volume | Check the number and size of containers. Tesco lists 4 × 500ml and 8 × 250ml energy-drink packs; each totals 2 litres but is not a 2-litre bottle. | I need around 2 litres for adult guests, but I can use a multipack if a single bottle is not essential. |
| Serving size | Compare 250ml and 500ml cans as individual portions. Red Bull states that its 250ml can contains 80mg caffeine; check caffeine per can for other products. | Smaller sealed servings may suit my gathering better than handing out 500ml cans. |
| Sugar and caffeine | Read both figures for the exact variant. Monster Energy states that its 500ml Monster Ultra has 0g sugar and 150mg caffeine; zero sugar does not mean caffeine-free. | Some adult guests may want a zero-sugar drink, while others may not want caffeine. |
| Mixed-age guests | Plan separate drink options for children. For England, the Department of Health and Social Care has announced an under-16 sales restriction from April 2027, subject to Parliamentary approval, for drinks other than tea or coffee containing more than 150mg caffeine per litre. | I need refreshments for younger guests as well as any energy drinks bought for adults. |
Common buying mistakes
-
Confusing a 2-litre multipack with one bottle
Four 500ml cans and eight 250ml cans both total 2 litres, but give guests different individual serving sizes.
Check the container count as well as the total volume before choosing a format.
-
Reading zero sugar as caffeine-free
Monster Energy states that its 500ml Monster Ultra contains 0g sugar and 150mg caffeine.
Check sugar and caffeine separately on the exact flavour and can size.
-
Overlooking younger guests
The Department of Health and Social Care has announced an England sales restriction from April 2027, subject to Parliamentary approval, for qualifying high-caffeine drinks sold to under-16s. The announced threshold is more than 150mg caffeine per litre, excluding tea and coffee.
Plan caffeine-free drinks for children and for guests who do not want an energy drink.
-
Assuming a named retailer has the exact pack
Relentless names Tesco and Sainsbury's as retailers, but that does not identify which flavours or pack sizes a particular shop has.
Check the exact product and pack size at the retailer you intend to use before planning BBQ quantities.
Brands and retailers to compare
Red Bull
Tesco lists an 8 × 250ml Red Bull pack, giving 2 litres in smaller individual cans.
- Eight separate 250ml servings.
- Red Bull states that each 250ml can contains 80mg caffeine; the pack is not one 2-litre bottle.
Monster
Tesco lists Monster Ultra in a 4 × 500ml pack for shoppers seeking 2 litres in separate cans.
- Monster Energy describes its 500ml Ultra can as containing 0g sugar.
- Monster Energy also states that the 500ml Ultra can contains 150mg caffeine; check the exact pack label.
Relentless
Tesco lists Relentless Origin in a 4 × 500ml pack, another 2-litre total in individual cans.
- Four separate 500ml cans.
- Relentless names Tesco and Sainsbury's as retailers, but confirm the exact pack at your chosen shop.
Lucozade
Tesco lists Lucozade Energy Orange in a 4 × 380ml pack. Lucozade also names Energy, Sport, Zero and Alert as distinct ranges.
- A listed Energy multipack for shoppers considering a different pack volume.
- Four 380ml bottles total 1.52 litres, not 2 litres; check that you have chosen the intended Lucozade range.
Tesco
Tesco's energy-drink listings provide pack counts and container sizes to compare before a BBQ shop.
- Its listed examples include Red Bull, Monster and Relentless multipacks.
- Check the current listing or local shop for the particular flavour and pack you want.

Questions about BBQ energy drinks
Can I count on finding a single 2-litre energy-drink bottle?
Do not rely on that format without checking your retailer. Tesco lists energy-drink multipacks such as 4 × 500ml and 8 × 250ml that total 2 litres, but neither is a single bottle; its listings do not establish what every UK retailer stocks.
Which multipack gives me about 2 litres for a BBQ?
Both four 500ml cans and eight 250ml cans total 2 litres. Choose by the individual serving size you want for adult guests; Tesco lists 4 × 500ml options and an 8 × 250ml Red Bull pack.
Does a zero-sugar energy drink have no caffeine?
No. Monster Energy states that its 500ml Monster Ultra can contains 0g sugar and 150mg caffeine. Check both details on the exact drink rather than using its sugar label to judge caffeine content.
What under-16 sales change has been announced for England?
The Department of Health and Social Care has announced a ban on selling qualifying high-caffeine energy drinks to under-16s in England from April 2027, subject to Parliamentary approval. Its stated scope is drinks other than tea or coffee containing more than 150mg caffeine per litre, including shop, vending-machine and online sales; the announcement should not be treated as a rule for the rest of the UK.
