Shoppers choosing drinks for guests
Glass may appeal if presentation is the reason for buying. Crystal Cash & Carry lists Red Bull Glass in a pack of 24 × 250ml bottles, so consider whether you have a use and space for the whole pack.
Who is each format for?
Shoppers choosing an everyday drink
If you want fewer drinks at once, compare the pack counts and can sizes available to you. Tesco lists canned Red Bull, Monster and Relentless products, including some zero-sugar variants; the label on the exact drink matters more than its packaging material.
Shoppers checking caffeine carefully
If the drink is for someone who is pregnant, breastfeeding, sensitive to caffeine or young, check its caffeine statement and warnings before choosing it. NHS pregnancy guidance counts caffeine from other foods and drinks towards its daily limit.
What should you check before buying?
Start with how many drinks you will use, then compare the contents of the container you expect to finish.
| Priority | What to check | Your needs |
|---|---|---|
| Pack and format | Check the bottle or can size, pack count and space needed to store it. Crystal Cash & Carry lists Red Bull Glass as 24 × 250ml bottles; Tesco also lists individual canned drinks. | I only want a few drinks for now, or I need enough bottles to serve a group. |
| Caffeine | Read the amount per 100ml and work out the amount in the container. Sainsbury’s lists Relentless Origin at 32mg per 100ml, or 160mg in its 500ml can. | If I finish the whole can, I want to know how much caffeine that adds to what I have elsewhere. |
| Sugars | Compare sugars per 100ml and per bottle or can; check the exact variant when looking for a zero-sugar option. Crystal Cash & Carry lists 11g sugars per 100ml for Red Bull Glass, or 27.5g per 250ml bottle. | I want to compare drinks by what is in the amount I will consume, not assume glass changes the contents. |
| Who will drink it | Read high-caffeine warnings and check current rules where you shop. NHS guidance says pregnant people should not have more than 200mg of caffeine a day from all sources. | Before buying drinks for a shared shop, I need to know who they are for. |
What is easy to overlook?
-
Assuming glass means different nutrition
Packaging does not tell you how much sugar or caffeine a drink contains. Crystal Cash & Carry lists Red Bull Glass at 11g sugars per 100ml and states that it contains caffeine.
Compare the nutrition panel and caffeine statement on the exact bottle and can you are considering.
-
Comparing unlike container sizes
A per-100ml figure does not describe the amount in a whole container. Sainsbury’s lists Relentless Origin at 32mg caffeine and 3.7g sugars per 100ml: its 500ml can contains 160mg caffeine and 18.5g sugars.
Compare figures for the amount you intend to drink, particularly when weighing a 250ml bottle against a 500ml can.
-
Committing to a glass multipack for one drink
The Red Bull Glass listing from Crystal Cash & Carry is for 24 bottles, which need somewhere to be kept and care when carried.
Check the pack quantity, delivery terms and storage space before ordering. If you only want to try one drink, consider an individual container instead.
-
Buying for someone without checking the warning
Energy-drink labels can identify groups for whom the drink is not recommended. Sainsbury’s Relentless Origin listing warns against use by children, pregnant or breastfeeding women, and people sensitive to caffeine.
Check the label and who the drink is for; a non-caffeinated choice avoids adding caffeine to a shared shop.
Which brands are relevant?
These brand references illustrate formats and product lines to compare; they do not imply that every variant has the same ingredients or comes in glass.
Red Bull
Crystal Cash & Carry lists Red Bull Glass in 250ml bottles sold as a 24-pack. Tesco lists Red Bull canned products, including Sugar Free and Zero.
- The listed glass bottle provides a specific packaging choice.
- Its 24-bottle pack is a larger commitment than buying a single drink; check the exact variant’s label when comparing contents.
Monster
Tesco lists Monster canned products, including Ultra and Zero Sugar variants.
- The listed variants give shoppers canned choices to compare.
- Check caffeine and sugars on the particular can rather than treating all Monster variants as identical.
Relentless
Sainsbury’s lists Relentless Origin in 500ml cans sold as a four-pack.
- Sainsbury’s lists 32mg caffeine and 3.7g sugars per 100ml for this Origin product.
- Account for the full 500ml can when comparing it with a 250ml drink.
Lucozade
Tesco lists Lucozade Energy drinks in bottles alongside separately named Lucozade Sport products.
- The listed Energy products offer bottled alternatives to consider.
- Check whether you are looking at Energy or Sport, then read that product’s nutrition and caffeine information.

Questions about your first shop
Does a glass bottle change what is in an energy drink?
No conclusion about caffeine or sugars follows from the packaging alone. Crystal Cash & Carry lists Red Bull Glass at 11g sugars per 100ml and states that it contains caffeine; compare the exact bottle and can labels for the amount you would drink.
Is a glass-bottle energy drink practical for a first food shop?
It can make sense if you want the presentation and will use a multipack. The Red Bull Glass product listed by Crystal Cash & Carry contains 24 × 250ml bottles, so check whether you have enough use and storage space before ordering it.
Can an under-16 buy a high-caffeine energy drink?
There is no single UK-wide answer established here. In a July 2026 announcement, GOV.UK described a planned England ban from April 2027 on sales to under-16s of drinks other than tea or coffee containing more than 150mg caffeine per litre; check the current rules and retailer conditions where you shop.
What should a pregnant shopper check on an energy-drink label?
Check its caffeine content alongside caffeine from other foods and drinks. NHS guidance says pregnant people should not have more than 200mg of caffeine a day; Sainsbury’s Relentless Origin listing also states that the drink is not recommended for pregnant or breastfeeding women.
