Hosts serving mixed preferences
Offer a choice between sugar-containing and zero-sugar drinks, with a caffeine-free sparkling drink alongside them. Compare the size of each individual can or bottle, not just the number in a multipack.
Who is choosing the drinks?
A mixed brunch group may need more than one drink choice: a preferred flavour or sugar formulation does not settle whether its caffeine content suits every guest.
Adults looking for a zero-sugar option
Choose by both the sugar declaration and caffeine per whole can. Monster lists zero sugar for Ultra, but also lists 150mg caffeine in its 500ml can.
Hosts with guests who may avoid caffeine
Include a caffeine-free alternative rather than assuming an energy drink will suit children, pregnant guests or people sensitive to caffeine. Check the warning on each pack; NHS pregnancy guidance also counts caffeine from other food and drink towards its daily limit.
What should you check?
Start with the amount in one complete drink, then compare formulations and flavours. A multipack helps serve a group, but its individual cans or bottles still determine what each guest receives.
| Priority | What to check | Your needs |
|---|---|---|
| Caffeine per drink | Read the milligrams for the complete can or bottle, not just a concentration per litre. Red Bull lists 80mg per 250ml Original can; Monster lists 150mg per 500ml Ultra can. Include coffee, tea and other caffeine consumed that day. | I want guests to know how much caffeine is in the drink they actually open, especially if brunch includes coffee or tea. |
| Sugar formulation | Compare the sugar declaration for the exact variant and serving size. Monster describes Ultra as zero sugar, while Lucozade describes its sparkling Energy range as containing glucose; these are not interchangeable formulations. | Some guests want a zero-sugar drink, while others may prefer a conventional or glucose-containing option. I would rather make those choices clear than group them all together. |
| Serving size | Check whether each unit is a 250ml can, a 500ml can or another size. Use the caffeine and nutrition information for that complete unit when comparing options. | A smaller individual drink may fit the occasion better for some guests; others may specifically want a larger can. |
| Flavour and fizz | Choose the stated flavour and confirm carbonation on the exact product. Monster describes Ultra as light citrus-flavoured, while Lucozade describes its Energy range as sparkling and glucose-containing. | For a daytime gathering, I want guests to be able to choose a flavour they like rather than expecting one energy drink to suit the whole table. |
| Guest suitability | Read the pack warning before serving. GOV.UK says drinks with more than 150mg caffeine per litre require a warning about suitability for children, pregnant women and people sensitive to caffeine. NHS guidance limits caffeine in pregnancy to 200mg a day from all sources. | If children or guests avoiding caffeine are coming, I need a caffeine-free drink available without making them choose a caffeinated one. |
Common buying mistakes
-
Reading “zero sugar” as “low caffeine”
Sugar and caffeine are separate product details. Monster lists zero sugar for Ultra alongside 150mg caffeine in a 500ml can.
Compare caffeine for the entire can and take account of coffee, tea or other caffeine served at brunch.
-
Treating every can as the same serving
Red Bull lists 80mg caffeine in a 250ml Original can, whereas Monster lists 150mg in a 500ml Ultra can. Choosing by can count alone misses those differences.
Check volume and caffeine per individual drink before deciding how many and which sizes to put out.
-
Assuming all sparkling energy drinks have similar sugar content
Lucozade describes its Energy range as containing glucose, Monster describes Ultra as zero sugar, and Tesco lists 19g sugars per 500ml Relentless Origin can.
Separate sugar-containing and zero-sugar choices, then check the nutrition panel for the exact flavour and pack size purchased.
-
Making energy drinks the only sparkling choice
A caffeinated drink will not suit every guest. UK high-caffeine warnings identify children, pregnant women and people sensitive to caffeine; NHS pregnancy guidance counts caffeine from all sources.
Put out water and a caffeine-free sparkling drink as well as any energy drinks.
Brand and range references
These examples show why the exact variant matters. Range descriptions do not replace the nutrition panel and warnings on the drink you buy.
Red Bull
Its 250ml Original can is a smaller-format conventional energy-drink option for adults who want that style of sparkling drink.
- Red Bull lists 80mg caffeine per 250ml Original can.
- Original is not the zero-sugar variant. Check the exact can if choosing between Original, Sugarfree and Zero.
Monster
Monster Ultra is a light citrus-flavoured, zero-sugar option in a larger 500ml can.
- Monster lists zero sugar for its 500ml Ultra can.
- Monster also lists 150mg caffeine per 500ml Ultra can, so its sugar declaration should not stand in for a caffeine check.
Relentless
Tesco describes Relentless Origin as a carbonated 500ml energy drink containing both sugar and sweetener.
- Tesco lists 19g sugars per 500ml can of Relentless Origin, giving a specific figure to compare with the chosen pack.
- Other Relentless variants have different formulations; check the exact variant rather than applying Origin’s nutrition figure across the range.
Lucozade Energy
Lucozade describes its Energy range as sparkling and containing glucose, making it a distinct choice from a zero-sugar energy drink.
- The range offers a glucose-containing sparkling option for guests choosing that formulation and flavour.
- Read the exact bottle or can for its sugar and caffeine information before comparing it with another drink.

Questions about serving energy drinks
How do I compare caffeine when brunch includes coffee or tea?
Read the caffeine amount for the entire energy-drink can or bottle, then account for other caffeine consumed that day. Red Bull lists 80mg per 250ml Original can and Monster lists 150mg per 500ml Ultra can; those figures describe different drinks and serving sizes.
Should I offer an energy drink to a pregnant guest?
Offer a caffeine-free choice rather than making an energy drink the default. NHS guidance says caffeine in pregnancy should not exceed 200mg a day from all sources, including energy drinks, coffee and tea; the guest can check any drink’s label against what else they have consumed.
What does a high-caffeine warning on a drink mean?
GOV.UK says drinks containing more than 150mg caffeine per litre require a warning about suitability for children, pregnant women and people sensitive to caffeine. The threshold is expressed per litre, so also read the caffeine amount for the individual can or bottle.
Does zero sugar mean an energy drink has less caffeine?
No: sugar content does not tell you the caffeine amount. Monster describes its 500ml Ultra can as zero sugar and lists 150mg caffeine, so check both details on the exact drink you choose.
Is the under-16 energy-drink sales ban already in force?
No England-wide ban announced for April 2027 is in force as of October 2026. GOV.UK’s July 2026 announcement says England will ban sales of high-caffeine energy drinks to under-16s from April 2027; it does not establish the same rule for the rest of the UK. Regardless of a sales rule, provide a caffeine-free option when children attend brunch.
