Hosts serving adults with different preferences
A choice of can sizes, sugar statuses and flavours lets guests check what they are picking up. Keep non-caffeinated sparkling drinks available too.
Who is choosing the drinks?
Guests looking for sugar-free options
Red Bull Sugarfree and Monster Zero Sugar offer different can sizes. Their manufacturers state different caffeine amounts per can, so a sugar-free label is not enough to compare servings.
Hosts with children or guests avoiding caffeine
Check product warnings before setting drinks out. Relentless advises against its Guava drink for children, people sensitive to caffeine, and those who are pregnant or nursing; non-caffeinated choices give these guests another option.
What should you check?
Start with the caffeine in a whole can and who will be drinking it, then choose the sugar status, serving size and flavours that fit the gathering.
| Priority | What to check | Your needs |
|---|---|---|
| Caffeine and can size | Compare caffeine per whole can, not just can volume. Red Bull states 80 mg for a 250 ml Sugarfree can; Monster Energy states 160 mg for a 500 ml Zero Sugar can on its UK product page. | I want guests to see how much caffeine is in the serving they actually take, especially when choosing between smaller and larger cans. |
| Sugar and sweeteners | Read the sugar declaration and ingredient list on the exact variety. Monster Energy states 0 g sugar per 500 ml Zero Sugar can; Red Bull lists sucralose and acesulfame K in Sugarfree. | Some guests may prefer a sugar-free drink, while others may want a different formula. I would rather offer a choice than assume the labels mean the same thing. |
| Sparkling flavours | Check the stated flavour and carbonation of the exact drink. A fruit flavour does not establish its sugar or caffeine content; inspect the can before treating it as an alternative to a sugar-free option. | For an outdoor gathering, I want more than one flavour without overlooking the ingredients or caffeine warning on a fruit-flavoured can. |
| Guest suitability | Read the product warning and provide non-caffeinated drinks. Relentless advises against Guava for children, caffeine-sensitive people, and those who are pregnant or nursing. NHS pregnancy guidance says caffeine from all sources should total no more than 200 mg a day. | If children are attending or a guest is avoiding caffeine, I need a clearly separate sparkling option that is not an energy drink. |
Common buying mistakes
-
Assuming zero sugar means little caffeine
Monster Energy states that a 500 ml Zero Sugar can contains 160 mg caffeine, while Red Bull states 80 mg for a 250 ml Sugarfree can. Sugar status does not tell you the caffeine amount.
Compare the caffeine declaration for the whole can and choose can sizes deliberately.
-
Setting out only energy drinks for mixed-age guests
Relentless advises against its Guava drink for children and people sensitive to caffeine, as well as those who are pregnant or nursing. One drinks table may serve people for whom that product is not recommended.
Make non-caffeinated sparkling drinks easy to identify and keep energy drinks as an optional choice for adults.
-
Judging a fruit-flavoured drink by its flavour name
A guava or berry description tells guests about flavour, not whether the drink is sugar-free or how much caffeine a can contains.
Check the ingredients, nutrition panel and caffeine warning for the exact variety and can size you buy.
Brand and retailer references
Red Bull
Original and Sugarfree 250 ml cans provide a smaller-can route for a garden party.
- Red Bull states that both its original drink and Sugarfree contain 80 mg caffeine per 250 ml can.
- Sugarfree still contains caffeine; check whether the drink is appropriate for each guest rather than relying on the sugar-free label.
Monster Energy
Zero Sugar is a larger-can option for an adult who wants a 500 ml serving.
- Monster Energy’s UK Zero Sugar information states 0 g sugar and 160 mg caffeine per 500 ml can.
- That is more caffeine in one can than the 80 mg Red Bull states for its 250 ml Sugarfree can; the serving sizes also differ.
Relentless
Guava provides a fruit-flavoured sparkling energy-drink choice.
- The named guava variety adds a different flavour for adults who want one.
- Relentless says Guava is not recommended for children, people sensitive to caffeine, pregnant women or women who are nursing.
Lucozade Alert
Lucozade describes Alert as a sparkling, high-caffeine drinks range.
- It offers another branded flavour range to consider for adult guests.
- Compare the caffeine, sugar and ingredients on the particular pack you intend to serve.
Tesco
Tesco is a retailer, not an energy-drink manufacturer. Its online category lists products from several of the brands discussed here.
- Tesco’s category includes listings for Red Bull Sugar Free, Monster Zero Sugar and Relentless Origin.
- Check the current listing for the exact variety and pack size rather than treating a category listing as a product specification.

Questions about serving energy drinks
Should I put energy drinks out for children at a garden party?
Provide non-caffeinated drinks for children instead of treating energy drinks as a general party choice. Check each product warning: Relentless, for example, says its Guava drink is not recommended for children.
What if a guest is pregnant?
Offer a non-caffeinated alternative rather than assuming an energy drink is suitable. NHS guidance says caffeine during pregnancy should total no more than 200 mg a day from all sources, including drinks and food; a guest would need to account for what they have already consumed.
Does sugar-free mean lower caffeine?
No: sugar status does not establish caffeine content. Red Bull states that Sugarfree contains 80 mg caffeine per 250 ml can, while Monster Energy states 160 mg per 500 ml Zero Sugar can. Compare amounts for the whole cans, noting that their sizes differ.
How can guests check what they are drinking outdoors?
Keep the original cans available so guests can read the caffeine, ingredient and warning information for the exact drink. Set non-caffeinated sparkling options apart from energy drinks so the choice is clear.
