Hosts planning drinks for adult guests
Count the individually packaged drinks you want to offer, then compare pack counts and can sizes. If you are providing both regular and zero-sugar drinks, plan how many cans of each to have available.
Who is this for?
For an adult Christmas party, the useful starting point is how many sealed servings to provide and whether guests will want a choice of can sizes or sugar content.
Hosts choosing smaller servings
A 250ml can gives each guest a smaller single serving than a 500ml can. Can size alone does not tell you how much caffeine or sugar a particular drink contains, so read its label as well.
Hosts offering a zero-sugar choice
Look for a clearly labelled zero-sugar multipack for guests who want to avoid sugar. Check its caffeine declaration separately, and provide a non-caffeinated drink option too.
What to check before buying
Start with the number of individual cans, then check what each can contains. A larger pack and a larger can solve different hosting needs.
| Priority | What to check | Your needs |
|---|---|---|
| Servings | Count the cans and note their volume. Compare the number of sealed servings with the number of adult guests you expect. | I want enough individual drinks to offer guests without treating a large can as several separate servings. |
| Caffeine per can | Read the caffeine amount for the exact drink and can size. Red Bull states 80mg per 250ml Original can; Monster states 160mg per 500ml Original Green can. These figures describe those products, not every can of either size. | Some guests may want a smaller can or no caffeine. I need the product information available so they can choose for themselves. |
| Sugar choice | Check sugars per can on regular drinks and the exact label on zero-sugar variants. A zero-sugar label does not establish that the drink is caffeine-free. | I would like to offer both regular and zero-sugar choices without presenting either as suitable for everyone. |
| Guest suitability | Read the exact pack warnings before serving. The NHS identifies energy drinks as a caffeine source and advises pregnant people not to exceed 200mg of caffeine a day from all sources. | I want guests to be able to see what they are choosing, with non-caffeinated soft drinks available as another option. |
| Pack format | Confirm that the listing is for cans if that matters to your plans. Tesco and Sainsbury’s list Lucozade Energy multipacks in 380ml bottles, rather than cans. | Bottles would work for my party only if I do not specifically need canned servings. |
Common buying mistakes
-
Treating 250ml and 500ml cans as the same serving
Can size changes what one guest receives. For the cited Original drinks, Red Bull states 80mg caffeine and 27g sugars per 250ml can, while Monster states 160mg caffeine and 55g sugar per 500ml Original Green can.
Choose the serving size deliberately, check the figures for the exact variants you buy and keep their labels available to guests rather than decanting the drinks into unlabelled cups.
-
Assuming zero sugar means no caffeine
A sugar declaration does not describe caffeine content. Someone looking for a non-caffeinated drink needs a different choice from someone looking only to avoid sugar.
Check the caffeine declaration on the exact zero-sugar pack and offer non-caffeinated soft drinks as well.
-
Picking a bottled multipack when you need cans
The Lucozade Energy multipacks listed by Tesco and Sainsbury’s use 380ml bottles, so they do not provide the canned servings considered here.
Include them only if bottles work for the party; otherwise confirm the packaging format before ordering.
Brand and format references
These examples help distinguish can sizes and packaging formats; check the exact variant rather than applying one product’s label to a whole brand.
Red Bull
Tesco and Sainsbury’s list 250ml Red Bull multipacks in regular and sugar-free variants.
- The 250ml format offers a smaller individual can. Red Bull states that its Original contains 80mg caffeine and 27g sugars per can.
- The Original figures do not describe Sugar Free or Zero; check the label of the variant you choose.
Monster
Tesco and Sainsbury’s list 500ml Monster multipacks, including Ultra zero-sugar variants.
- The 500ml format gives a guest a larger single serving. Monster states that Original Green contains 160mg caffeine and 55g sugar per can.
- Original Green figures should not be applied to an Ultra variant; check the exact can’s caffeine and nutrition information.
Relentless
Tesco and Sainsbury’s list Relentless Origin in a 4 x 500ml canned multipack.
- Four individually packaged 500ml cans offer a smaller pack count for guests who want that can size.
- Relentless’ published caffeine declaration and suitability warning cited here concern Guava, not Origin. Read the Origin pack’s own label.
Lucozade
Tesco and Sainsbury’s list Lucozade Energy multipacks in 380ml bottles.
- A bottled format gives hosts another individually packaged option if cans are not essential.
- These listed bottle multipacks do not meet a requirement for cans; check the exact product label for its contents.
Sainsbury’s Blue Bolt
Sainsbury’s lists regular and Zero Blue Bolt options in 6 x 250ml cans.
- The six-can, 250ml format is another smaller-can option at that retailer.
- Check the exact regular or Zero pack for its caffeine declaration, nutrition information and warnings.

Questions about party multipacks
Are energy drinks suitable for every party guest?
No. Offer a non-caffeinated option and let guests see the exact drink’s label. The NHS identifies energy drinks as a caffeine source and advises pregnant people not to exceed 200mg of caffeine a day from all sources. Product warnings can differ by variant.
How does can size affect the caffeine decision?
Compare caffeine per can, not size alone. Red Bull states 80mg caffeine in a 250ml Original can, while Monster states 160mg in a 500ml Original Green can. Check other variants individually rather than applying those figures to every 250ml or 500ml drink.
Does zero sugar mean caffeine-free?
No. Zero sugar describes sugar content, not caffeine content. Read the caffeine declaration on the exact zero-sugar multipack if a guest wants to avoid caffeine.
Will England restrict sales of energy drinks to under-16s?
The Department of Health and Social Care announced a ban on sales of high-caffeine energy drinks to under-16s in England from April 2027. That is a future England-specific rule, not a statement of the current legal position across the whole UK. Check the applicable rules and the retailer’s policy when buying.
