For drinks taken into a festival, check whether drinks and their containers are allowed before choosing glass or a can: Victorious Festival’s prohibited-items page dated 21 August 2024 barred beverages other than an empty, non-glass water vessel. If your event permits canned drinks, compare caffeine and sugars per whole container; consider glass for an off-site setting only when the venue permits it and the exact product’s packaging is confirmed.
Check the named event’s current entry rules before choosing a container. Victorious Festival’s prohibited-items page dated 21 August 2024 excluded beverages apart from an empty, non-glass water vessel, so changing from glass to a can would not, by itself, make a drink admissible there.
If you want to serve an energy drink in glass, confirm both that your setting permits glass and that the exact product comes in a glass bottle. A listing that merely says “bottle” does not establish the material.
Look at the figures for the drink and container you intend to use. Red Bull states 80 mg caffeine per 250 ml can of Original, while Monster states 160 mg per 500 ml can of Absolutely Zero; those figures describe different products and serving sizes.
Start with the event’s rules for bringing in drinks, then check the exact pack and its label. A permitted container matters more for entry than how a drink will look alongside food.
| Priority | What to check | Your needs |
|---|---|---|
| Event and container rules | Check the current rules for beverages, glass, cans and any camping or vendor arrangements. Victorious Festival’s prohibited-items page dated 21 August 2024 allowed only an empty, non-glass water vessel as an exception to its beverage restriction; it does not set the rules for other events. | I want to know whether I can bring the drink in at all, not just whether its container is glass. For an off-site food display, I need the venue’s permission before choosing glass. |
| Caffeine per container | Read the caffeine figure and its stated basis: per 100 ml or per can. Red Bull states 80 mg per 250 ml can of Original; Monster states 160 mg per 500 ml can of Absolutely Zero. Check the exact variant’s warning as well. | A smaller can and a larger can do not represent the same amount to drink. I also want to account for any coffee, tea or other energy drinks I plan to have that day. |
| Sugars and variant | Compare sugars for the whole container on the exact product label. Red Bull states 27 g per 250 ml can of Original, while Monster states 0 g per 500 ml can of Absolutely Zero; a zero-sugar label does not mean caffeine-free. | If I am choosing between a regular and a zero-sugar drink, I want to compare their sugars without overlooking caffeine or confusing one variant with another. |
An attractive presentation does not override an organiser’s container policy. Some rules restrict drinks themselves as well as glass: Victorious Festival’s prohibited-items page dated 21 August 2024 did so.
Read the named event’s current prohibited-items information, including any separate camping or vendor terms, before buying drinks to take inside.
Container sizes and variants change the amount you are comparing. Red Bull states 80 mg caffeine in a 250 ml Original can; Monster states 160 mg in a 500 ml Absolutely Zero can.
Compare the caffeine in the full container, account for other caffeine you intend to have, and read the warning on the exact drink.
Monster lists 0 g sugar and 160 mg caffeine for a 500 ml can of Absolutely Zero. The two label details answer different questions.
If sugar is your reason for choosing a variant, check its caffeine separately and confirm that its packaging is permitted at your event.
A bottle-format listing does not establish the container material. Tesco lists Lucozade Energy drinks in several formats, but a format name alone is not proof of glass.
Confirm the material for the exact product before planning a glass-bottle food display.
These examples help distinguish container sizes and variants; a brand name does not establish that a particular drink is sold in glass or allowed into an event.
Red Bull describes Original as a 250 ml canned energy drink.
Monster describes Absolutely Zero as a zero-sugar drink in a 500 ml can.
Sainsbury’s lists Relentless Origin as a 500 ml energy drink.
Tesco lists Lucozade Energy and Lucozade Energy Zero as distinct options, including 380 ml and 500 ml formats.
These energy drinks are canned alternatives for a festival that permits you to bring in cans. Check the named event’s current drink and container rules before choosing one; these are not glass-bottled options.

If your event permits canned drinks, this Tropical Flavour pack provides 24 individual 250 ml servings rather than glass bottles. Check the exact label and event rules before taking any inside.
No image available
If cans are permitted and you want a zero-sugar variant, this pack contains four 500 ml servings. Check caffeine on the Ultra label rather than using figures for Monster Absolutely Zero, which is a different variant.

For an event that permits cans, this Sugarfree pack offers twelve 250 ml servings. Read the Sugarfree label for its caffeine and nutrition details rather than applying Red Bull Original’s sugar figure.
No image available
If the event allows canned drinks, this Original Green pack contains nine 500 ml servings. Compare its own caffeine and sugars per can; the figures for Monster Absolutely Zero do not describe Original Green.

For a setting that permits cans, this pack contains twenty-four 250 ml servings. Check the nutrition and caffeine information on the exact pack when comparing it with another variant or container size.
Check the named festival’s current rules before buying: permission is event-specific, not a rule shared by every UK festival. Victorious Festival’s prohibited-items page dated 21 August 2024 barred beverages other than an empty, non-glass water vessel, so switching to a can would not resolve that event’s beverage restriction.
Consider it for an off-site or controlled food-service setting only if glass is permitted there and the exact energy drink is confirmed to come in glass. A product described simply as a “bottle” does not answer the packaging question.
Compare the amount in the whole container, checking whether the label gives caffeine per 100 ml or per can. Red Bull states 80 mg in a 250 ml can of Original, Monster states 160 mg in a 500 ml can of Absolutely Zero, and Sainsbury’s lists Relentless Origin at 32 mg per 100 ml; also account for other caffeine you intend to have.
Check the exact variant’s ingredients, nutrition information, container size and caffeine warning, as well as its sugars and caffeine figures. For example, Sainsbury’s Relentless Origin listing says it is not recommended for children, pregnant or breastfeeding women, or people sensitive to caffeine.
