Hosts offering an adult zero-sugar option
If guests specifically want an energy drink without sugar, compare the caffeine in a whole can as well as its sugar claim. A zero-sugar label does not mean the drink is caffeine-free.
Who needs which drinks?
Hosts serving a mixed guest list
Keep caffeine-free drinks separate and easy to identify for guests who avoid caffeine or do not want an energy drink. The NHS advises a daily caffeine limit of 200 mg during pregnancy, counting caffeine from all sources.
Hosts buying multipacks for self-service
Compare the number of cans, volume per can and caffeine per can before ordering. Check the exact variant and whether the order can arrive at the wedding location in time.
What should you check?
Choose the drinks you will offer separately from the pack size you will buy: first identify zero-sugar and caffeine-free options, then compare complete cans and the quantity needed for the buffet.
| Priority | What to check | Your needs |
|---|---|---|
| Zero-sugar status | Read the sugar information for the exact variant. Check caffeine separately; a sweetener in the ingredients does not establish that a drink has no sugar. | I want guests looking for a zero-sugar drink to recognise it without mistaking it for a caffeine-free choice. |
| Caffeine per can | Compare the stated amount for the complete can, not volume alone. Red Bull states 80 mg for Sugarfree 250 ml; Monster Energy UK states 150 mg for Ultra 500 ml and 160 mg for its reviewed Zero Sugar 500 ml. | A smaller single serving may suit an adult guest who wants an energy drink but is comparing how much caffeine is in each unopened can. |
| Caffeine-free choice | Identify a drink explicitly labelled caffeine-free and display it apart from energy drinks. The NHS advises no more than 200 mg caffeine a day during pregnancy, including caffeine from other drinks and foods. | Some of my guests may avoid caffeine, be sensitive to it or simply prefer a soft drink that is not an energy drink. |
| Buffet quantity | Check cans per pack and volume per can against the number you intend to serve. Confirm the exact variant, delivery location and arrival date before ordering. | I need enough clearly identifiable cans for self-service without assuming that everyone will choose an energy drink. |
What can go wrong?

Assuming zero sugar means caffeine-free
Red Bull Sugarfree and the reviewed Monster zero-sugar drinks all contain caffeine, according to their brands. A sugar label alone cannot tell guests whether a drink meets their caffeine preference.
Label energy drinks as containing caffeine and put caffeine-free drinks in a separate, visible place.
-
Treating 500 ml and 250 ml cans as equivalent servings
Monster Energy UK states 150 mg or 160 mg caffeine per reviewed 500 ml can, while Red Bull states 80 mg per 250 ml Sugarfree can. Guests choosing one whole can are choosing different caffeine amounts.
Show the can size and caffeine per can where guests make their selection; choose the larger format only if it suits the adult guests you are catering for.
-
Putting a sweetened drink in the zero-sugar section
Relentless Guava lists both sucrose and sucralose. The presence of a sweetener does not make that particular variant a zero-sugar drink.
Use the exact variant’s ingredients and nutrition information to decide where it belongs, rather than relying on its brand or flavour.
-
Leaving the order check until the event
A multipack’s stated can count does not establish that it can be delivered to your location by the required date.
Before placing the order, check the selected pack, delivery location and arrival date against the wedding schedule.
Relevant brand references
Brand ranges contain different variants, so use the information for the exact can rather than applying one product’s sugar or caffeine details to the whole range.
Red Bull
Sugarfree 250 ml is a smaller-can option for a clearly labelled adult energy-drink section.
- Red Bull states that Sugarfree contains no sugars and has 80 mg caffeine per 250 ml can.
- Sugarfree still contains caffeine; it does not replace a caffeine-free buffet option.
Monster Energy
The reviewed zero-sugar 500 ml variants provide a larger can, with caffeine amounts that differ by variant.
- Monster Energy UK states that Ultra has 0 g sugar and 150 mg caffeine per 500 ml can; its reviewed Zero Sugar product has 0 g sugar and 160 mg caffeine per 500 ml can.
- Check the particular variant and caffeine amount before using a 500 ml can as a self-service option.
Relentless
Relentless names Tesco and Sainsbury’s as retailers, but that does not establish which variants are currently available.
- Its published ingredients allow the Guava variant to be assessed separately from other Relentless drinks.
- Guava lists sucrose as well as sucralose, so do not place that variant in a zero-sugar section. Relentless also says Guava is not recommended for children, caffeine-sensitive people, pregnant women or women who are nursing.

Questions about serving energy drinks
Does zero sugar mean an energy drink is low in caffeine?
No. Red Bull states that a 250 ml Sugarfree can contains 80 mg caffeine, while Monster Energy UK states 150 mg for its reviewed 500 ml Ultra can and 160 mg for its reviewed 500 ml Zero Sugar can. Check caffeine per complete can independently of the sugar claim.
Should zero-sugar energy drinks be the option for pregnant guests?
Do not treat them as the default option. The NHS advises no more than 200 mg caffeine a day during pregnancy and identifies energy drinks as one source; caffeine from other foods and drinks counts too. Provide a clearly identifiable caffeine-free alternative.
Can a drink containing sweetener go in the zero-sugar section?
Only if the exact product’s sugar information supports that description. Relentless Guava lists both sucrose and sucralose, so the presence of a sweetener does not make that variant a zero-sugar choice.
How should the cans be displayed at a self-service buffet?
Keep caffeinated energy drinks apart from caffeine-free soft drinks and leave the product labels visible. Distinguish 250 ml from 500 ml cans and show caffeine per can so guests can identify what they are choosing.
Does a retailer listing confirm a zero-sugar variant will be available?
No. Relentless lists Tesco and Sainsbury’s as retailers, but that does not establish current stock of a particular variant. Check the exact product and the delivery arrangements before ordering for the wedding.
