For several lecture lunches, choose a can count you can store and use, then decide whether you want the original recipe, zero sugar or an explicitly caffeine-free drink. A regular cola may suit a preference for its original flavour, but check its sugar per can; zero-sugar cola is not necessarily caffeine-free, and caffeine-free versions need to be identified by their exact name.
The useful pack size depends on how often you take a can to lunch and where you will keep the remaining cans.
Individual cans are easy to set aside for lecture days. Compare the number of cans and their volume with the space available in your bag or shared fridge; a larger multipack is only practical if you can store and use it.
Compare the sugars figure for one can, not just the flavour name. Pepsi UK lists 15g sugars in a 330ml regular Pepsi can and 0g in a 330ml Pepsi Max can, so the exact variant makes a difference to sugar from the drink.
Look for an explicitly caffeine-free variant rather than relying on a zero-sugar label. Pepsi UK identifies Pepsi Max No Caffeine separately from standard Pepsi Max, while Coca-Cola Great Britain identifies Sprite Zero Sugar and Fanta Zero Sugar as caffeine-free.
Start with the drink you would actually take to lunch, then check its sugar, caffeine and ingredients before settling on a can count.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar per can | Read the sugars figure for the whole can; if the label uses per-100ml figures, account for the can’s volume. Pepsi UK lists 15g sugars per 330ml regular Pepsi can and 0g per 330ml Pepsi Max can. | I may take a fizzy drink to several lunches, so I want to know how much sugar each can contributes. The NHS advises keeping the amount and frequency of sugary drinks low. |
| Caffeine | Check the exact variant name and ingredients. Pepsi UK lists caffeine in standard Pepsi Max but identifies Pepsi Max No Caffeine as a separate product; Coca-Cola Great Britain identifies Sprite Zero Sugar and Fanta Zero Sugar as caffeine-free. | If I do not want caffeine at lunch, a zero-sugar label alone will not answer that question. |
| Ingredients | Read the label for the chosen flavour and variant, including its sweeteners and any phenylalanine statement. Do not transfer one version’s ingredient list to another. | A particular ingredient may matter to me, so I need to check the can I am buying rather than rely on the brand name. |
| Pack format | Check can volume, total can count and storage space. Tesco Groceries lists selected fizzy drinks in 8 x 330ml packs and selected zero-sugar colas in 24 x 330ml packs. | For occasional lecture lunches, I may prefer fewer cans to store; for more frequent use, I can consider a larger pack if there is room for it. |
Pepsi UK lists caffeine in standard Pepsi Max, while Pepsi Max No Caffeine is a separately named variant. A zero-sugar cola can therefore miss a caffeine-avoidance requirement.
Check the full variant name and ingredients, and choose one explicitly identified as caffeine-free when that matters.
Pepsi UK lists 15g sugars per 330ml regular Pepsi can. The NHS advises adults to keep the amount and frequency of sugary drinks low.
If you plan to take cans to several lunches each week, compare the regular and zero-sugar versions’ per-can labels before choosing.
Regular, zero-sugar and caffeine-free versions can have different ingredient lists. Pepsi UK, for example, lists sweeteners in Pepsi Max, while several named zero-sugar drinks carry a source-of-phenylalanine statement.
Check the exact flavour and variant on the current pack if a sweetener or ingredient statement affects your choice.
These ranges illustrate different flavours and variants; a brand name alone does not establish a particular can’s ingredients or caffeine status.
Coca-Cola Zero Sugar and Coca-Cola Zero Sugar Zero Caffeine are distinct cola variants. Tesco Groceries lists a 24 x 330ml Coca-Cola Zero Sugar multipack.
Pepsi Max and Pepsi Max No Caffeine offer two separately named zero-sugar cola choices. Tesco Groceries lists 24 x 330ml Pepsi Max multipacks.
Sprite Zero Sugar is a lemon-and-lime alternative to cola; Tesco Groceries lists an 8 x 330ml multipack.
Fanta offers a fruit-flavoured alternative to cola. Tesco Groceries lists Fanta Zero Orange in an 8 x 330ml multipack.
Dr Pepper is another flavour option; Tesco Groceries lists Dr Pepper Zero in an 8 x 330ml multipack.
Tesco Xero Cola is an own-label cola option listed by Tesco Groceries in an 8 x 330ml multipack.

A caffeine-free cola option in 24 individual 330ml cans for lunches spread across several weeks. Pepsi UK identifies its no-caffeine Pepsi Max variant as having no sugar. Check the pack’s sweeteners and source-of-phenylalanine statement if these matter to you.
No image available
This non-cola option contains eight 330ml cans, so it takes less storage space than a 24-can pack of the same can size. Check the exact label for caffeine, sweeteners and its source-of-phenylalanine statement if these affect your choice.
No image available
This caffeine-free cola comes as two packs of eight 330ml cans: 16 cans in total, rather than a single eight-can pack. Check the exact pack’s ingredients and source-of-phenylalanine statement if relevant to you.
No image available
The 24 individual 330ml cans suit someone with room to store a larger cola multipack. This is standard Coca-Cola Zero Sugar, which contains caffeine—not the separately named Zero Caffeine version. Check the exact label’s source-of-phenylalanine statement if it matters to you.
No image available
An apple-flavoured alternative to cola in 24 individual 330ml cans. If avoiding caffeine is important, check the caffeine information on the exact pack before choosing it; the sugar-free name does not answer that question.
No. A zero-sugar variant addresses sugar from the drink, but you still need to choose a flavour you want and check caffeine and ingredients. Pepsi UK, for example, lists caffeine in standard Pepsi Max but offers a separately named no-caffeine version.
Look for an explicitly caffeine-free variant. Pepsi UK identifies Pepsi Max No Caffeine, and Coca-Cola Great Britain identifies Coca-Cola Zero Sugar Zero Caffeine, Sprite Zero Sugar and Fanta Zero Sugar as caffeine-free. Check the exact pack name rather than assuming every drink from those brands is the same.
Choose according to how many lecture lunches you plan to pack and where the remaining cans will go. Tesco Groceries lists selected drinks in 8 x 330ml packs and selected zero-sugar colas in 24 x 330ml packs; compare the can count and volume before committing storage space.
Yes. Regular, zero-sugar, flavoured and caffeine-free versions can differ. Read the current label for the exact can, particularly if its sweeteners or a source-of-phenylalanine statement affect your choice.
