For an adult Sunday brunch, 250 ml cans make it easier to offer a smaller individual serving: Red Bull states that its Original contains 80 mg caffeine and 27 g sugars per can. Larger cans may suit adults who want that serving size, but Monster states that its Zero Sugar 500 ml can contains 160 mg caffeine. Keep a caffeine-free drink available for children and guests avoiding caffeine, and check the exact variant before serving.
If guests want their own cans, compare the number of cans with the number of adults who actually want an energy drink. Tesco lists Red Bull 8 × 250 ml multipacks alongside larger-can Monster multipacks; pack count alone does not describe the serving size.
Check the exact variant rather than relying on the brand name. Tesco lists Red Bull Sugar Free and Monster zero-sugar multipacks, while Monster states that its Zero Sugar 500 ml can contains 0 g sugar and 160 mg caffeine.
Plan a separate caffeine-free drink rather than assuming an energy-drink multipack will suit everyone. Relentless advises that its products are not recommended for children, pregnant or nursing women, or people sensitive to caffeine; the NHS also advises a daily caffeine limit during pregnancy.
Choose the serving size and the guests it is intended for before comparing flavours or pack counts. Read caffeine and sugar information for the exact variant, particularly when switching between 250 ml and 500 ml cans.
| Priority | What to check | Your needs |
|---|---|---|
| Caffeine per can | Compare the amount per can, not just per 100 ml. Red Bull states 80 mg per 250 ml Original can; Monster states 160 mg per 500 ml Zero Sugar can. The NHS says caffeine during pregnancy should not exceed 200 mg a day from all sources. | I want guests to be able to judge a whole can alongside any coffee, tea or cola they may also have at brunch. |
| Sugar and variant | Read the sugar declaration on the exact pack. Red Bull states 27 g sugars per 250 ml Original can; Monster states 0 g sugar per 500 ml Zero Sugar can. Do not treat a sugar-free name as a caffeine declaration. | Some adults may want a drink without sugar, while others may specifically want the Original Red Bull variant. |
| Guests and warnings | Check the pack warning and any retailer age-verification requirements. Relentless says its products are not recommended for children, pregnant or nursing women, or people sensitive to caffeine. | There will be guests for whom I should offer a caffeine-free drink instead of assuming the multipack suits the whole table. |
| Can and pack size | Check both the number of cans and the volume of each one. Tesco lists Red Bull 8 × 250 ml packs and Monster 4 × 500 ml packs; the same total volume can be divided into different-sized servings. | If several adults want one smaller can each, individual portions matter more to me than choosing by the pack’s total volume. |
An 8 × 250 ml pack and a 4 × 500 ml pack each contain 2 litres, but they divide that volume into different servings. Red Bull states 80 mg caffeine per 250 ml Original can, while Monster states 160 mg per 500 ml Zero Sugar can.
Decide whether guests want smaller or larger individual cans, then compare caffeine per can on the exact variant.
Sugar and caffeine are separate label details: Monster states that its Zero Sugar 500 ml can has 0 g sugar and 160 mg caffeine.
Check both declarations, and offer a caffeine-free drink to anyone who does not want caffeine.
In its July 2026 announcement, the Department of Health and Social Care and Department for Education described an England sales ban planned for April 2027 for under-16s, covering drinks other than tea or coffee with more than 150 mg caffeine per litre. That announcement does not establish a current rule across every UK nation.
For a purchase now, check the retailer’s age-verification requirements. Keep children’s drinks separate from high-caffeine energy drinks, and recheck the applicable rules for later purchases.
These examples help distinguish can formats and formulations; they do not mean that every product from a brand has the same ingredients or caffeine content.
Tesco lists Original and Sugar Free 8 × 250 ml multipacks, providing two small-can variants to distinguish when shopping for adults.

Tesco lists a Relentless Origin 4 × 500 ml multipack, another format for adults considering larger cans.

Do not treat high-caffeine energy drinks as children’s drinks; provide a separate option for them. In a July 2026 announcement, the Department of Health and Social Care and Department for Education said an England ban on sales to under-16s is planned for April 2027 for drinks other than tea or coffee containing more than 150 mg caffeine per litre. That is not a current UK-wide sales rule; check the retailer’s requirements when buying.
Red Bull states that its Original contains 80 mg caffeine per 250 ml can, while Monster states that its Zero Sugar contains 160 mg per 500 ml can. Read the label of the variant you buy rather than applying either figure to a different flavour or range.
No: sugar and caffeine are separate declarations. Monster states that its Zero Sugar 500 ml can contains 0 g sugar and 160 mg caffeine, so check both details on the exact pack.
The NHS advises no more than 200 mg caffeine a day during pregnancy, counting sources such as coffee, tea, cola, energy drinks, chocolate, guarana and some supplements. Check a drink’s caffeine declaration as part of that daily total.
The cited Joybuy listing for the Red Bull Energy Drink 8 × 250 ml pack says to store it in a cool, dry place and that it is best served chilled. Check the packaging of the pack you receive for its storage instructions and best-before date.
