For a top-up shop, choose a pack you expect to use: a zero-sugar variant if you want to avoid listed sugar, or a regular recipe if that particular flavour is your preference. Check caffeine and sweeteners on the exact label. Individual cans keep servings separate, while a 2-litre bottle suits planned sharing but may lose its fizz after opening.
The useful starting point is how much drink you need and which recipe details matter to the people who will drink it.
If you want cola, lemonade or a fruit-flavoured fizzy drink without listed sugar, compare the exact variant rather than the brand or flavour alone. Coca-Cola GB and Pepsi UK list 0g sugars per 100ml for Coca-Cola Zero Sugar and Pepsi Max respectively; both brands also list ingredients worth checking if caffeine or sweeteners matter to you.
Think about the next few meals or the occasion you are buying for. Tesco Groceries lists individual cans, multipacks and 2-litre bottles, giving you a choice between separately sealed servings and a bottle to share. A large bottle is less useful if much of it will remain open and lose its fizz.
Check whether the exact drink is a regular sugar-sweetened recipe or a zero-sugar variant. Department of Health and Social Care and NHS England oral-health guidance, published in September 2025, says sugar-sweetened fizzy drinks have no place in a child’s daily diet.
Choose the recipe first, then check the ingredients and pick a pack size that fits the occasion.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar content | Compare sugars per 100ml on the exact label, then check the serving size. Pepsi UK lists 4.5g sugars per 100ml for regular Pepsi and 0g for Pepsi Max; Coca-Cola GB lists 0g for Coca-Cola Zero Sugar. These figures describe those specific recipes, not every drink from either brand. | I want to choose between regular and zero-sugar recipes using the nutrition panel, rather than assume a fruit flavour or familiar brand tells me how much sugar is in the drink. |
| Caffeine and ingredients | Read the ingredient list and the full variant name. Coca-Cola GB and Pepsi UK list caffeine in standard Coca-Cola Zero Sugar and Pepsi Max and identify separate caffeine-free variants. Their standard zero-sugar pages also carry a source-of-phenylalanine statement. | If I need to avoid caffeine, I want a specifically labelled caffeine-free drink; the words ‘zero sugar’ alone do not answer that question. |
| Pack size | Check the number of cans, each can’s volume and the total volume. Tesco Groceries lists can multipacks alongside 2-litre bottles. Consider whether an opened sharing bottle will be finished while it still tastes as you expect. | For separate servings, I would choose cans in a quantity we can use. For a planned meal or gathering, a larger bottle may fit better. |
Standard Coca-Cola Zero Sugar and Pepsi Max list caffeine in their ingredients, according to their UK brand pages. Choosing by the sugar claim alone could leave you with the wrong variant if caffeine matters to you.
Read the full product name and ingredients; look for a specifically labelled caffeine-free variant.
Regular and zero-sugar drinks can sit within the same flavour family. Tesco Groceries lists both regular and zero-sugar fruit-flavoured formats, so ‘orange’ or ‘lemonade’ does not establish the sugar content.
Compare sugars per 100ml and the ingredients on the precise product you intend to buy.
A 2-litre bottle can suit a planned shared meal, but drink left after opening may lose its fizz before it is used.
If you expect to drink it on separate occasions, consider individual cans or a smaller pack instead.

These entries retain their positions in Joybuy’s Softdrinks Bestsellers list, which Joybuy says is ordered using sales and views and updated daily. The table is an excerpt, not a ranking of every fizzy drink or a comparison of which recipe suits your household.
| Rank | SKU name | Main specifications | Recommendation reasons | Platform |
|---|---|---|---|---|
| 2 | Coca-Cola Original Taste 24 × 330ml | 24 × 330ml cans; Original Taste | Joybuy lists this at rank 2. Its 24-can format is worth considering only if the household expects to use that many individual servings. | Joybuy |
| 5 | Diet Coke 18 × 330ml | 18 × 330ml cans; Diet Coke | Joybuy lists this at rank 5. Check the exact recipe and whether an 18-can pack fits your top-up plans. | Joybuy |
| 6 | Coke Zero 8 × 330ml | 8 × 330ml cans; Coke Zero | Joybuy lists this at rank 6. Eight separate cans offer a smaller pack than the other multipacks shown in this excerpt. | Joybuy |
| 9 | Coca-Cola Zero Sugar 18 × 330ml | 18 × 330ml cans; Zero Sugar | Joybuy lists this at rank 9. The larger can count matters if you are choosing between a short top-up and a supply for several people. | Joybuy |
These can multipacks cover caffeine-free and standard zero-sugar cola, a sugar-free apple drink and regular cola. Choose by the exact recipe and the number of cans you expect to use; they are not a substitute for comparing a sharing bottle if that is the format you need.

An apple-flavoured alternative to the cola packs, with 24 individual cans. That is a substantial quantity for a small top-up, so consider whether it fits your plans. Check the exact pack label if caffeine avoidance matters.
No image available
A regular-recipe cola in 24 separate cans for a household expecting to use that quantity. Compare its sugars-per-100ml figure and ingredients with a zero-sugar variant before choosing. Department of Health and Social Care and NHS England guidance says sugar-sweetened fizzy drinks have no place in a child’s daily diet.
No. Coca-Cola GB and Pepsi UK list caffeine in standard Coca-Cola Zero Sugar and Pepsi Max, while naming separate caffeine-free zero-sugar variants. Check the full product name and ingredient list if caffeine matters to you.
Choose by when and with whom you expect to drink it. Cans keep individual servings sealed until needed; a 2-litre bottle suits planned sharing, but drink left after opening may lose its fizz. Check the number of cans and total volume before choosing a multipack.
Department of Health and Social Care and NHS England oral-health guidance, published in September 2025, says drinks sweetened with sugar, including fizzy drinks, have no place in a child’s daily diet. Check the exact drink’s nutrition panel to distinguish a sugar-sweetened recipe from a zero-sugar variant.
Follow the instructions on the exact pack. Joybuy’s Coca-Cola Zero Sugar 24 × 330ml listing advises cool, dry storage and says to keep the pressurised container away from odours, heat and freezing temperatures; instructions for another product may differ.
