Students stocking a shared flat
If several people will share a bottle, check its instructions for use after opening. Separately sealed cans can be more practical when everyone drinks cola at different times.
Who is choosing?
Students comparing sugar content
Compare sugars per 100 ml on the exact packs you are considering. A zero-sugar label tells you about sugar, not caffeine or which sweeteners the drink contains.
Students looking for caffeine-free cola
Look for an explicit caffeine-free label. Pepsi Max Caffeine-Free and Coca-Cola Zero Sugar Caffeine Free are examples; standard Pepsi Max contains caffeine, according to Pepsi UK.
What should you check?
Settle the recipe first, then choose a pack that fits how many people will drink it and when.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar | Compare sugars per 100 ml on the nutrition labels. The Coca-Cola Company lists 10.6 g for Original Taste and 0 g for Zero Sugar Caffeine Free; Pepsi UK lists 4.5 g for regular Pepsi and 0 g for Pepsi Max. | I want a regular sweetened recipe, or I would rather choose one labelled zero sugar. Comparing the same volume helps me distinguish them. |
| Caffeine | Check for an explicit caffeine-free label and read the ingredients. Pepsi UK lists caffeine in Pepsi Max, despite its 0 g sugars per 100 ml. | For drinks I plan to have in the evening, I want to know whether this particular cola contains caffeine. |
| Ingredients | Read the sweeteners and warning statement on the exact pack. The Coca-Cola Company and Pepsi UK list aspartame and a source-of-phenylalanine statement for their specified caffeine-free zero-sugar colas. | I need to check ingredient-specific requirements rather than assume that all zero-sugar recipes are interchangeable. |
| Pack format | Compare total volume, individual can size, storage space and any instructions after opening. Tesco Groceries says to consume its listed 2-litre Diet Cola and Caffeine Free Diet Cola within 3 days of opening. | Will several flatmates finish a bottle promptly, or would separately sealed cans suit how we drink cola? |
Common buying mistakes
-
Assuming zero sugar means no caffeine
Pepsi Max has 0 g sugars per 100 ml but contains caffeine, according to Pepsi UK. The sugar claim alone cannot answer the caffeine question.
Choose a pack explicitly labelled caffeine-free when that distinction matters, and check its ingredients.
-
Treating every zero-sugar recipe as the same
Sweeteners and warning statements can differ between products. Specified Coca-Cola and Pepsi zero-sugar colas containing aspartame carry a source-of-phenylalanine statement.
Read the ingredients and warning on the exact flavour and pack you intend to buy.
-
Choosing a large bottle without checking its opened life
Tesco Groceries instructs customers to consume its listed 2-litre diet colas within 3 days of opening. That period matters if only one person drinks from the bottle occasionally.
Check the bottle’s own instructions; consider separately sealed cans if the bottle is unlikely to be finished in time.
-
Overlooking sugar when choosing a regular recipe
The Coca-Cola Company lists 10.6 g sugars per 100 ml for Original Taste. A larger serving contains more sugar than the per-100 ml figure alone shows.
If sugar content affects your choice, compare both the per-100 ml figure and the amount you expect to drink.
Brand and product-line references
Brand names alone do not establish a recipe: check the exact regular, zero-sugar or caffeine-free product.
Coca-Cola
The Coca-Cola Company lists Original Taste and Zero Sugar Caffeine Free as distinct UK recipes.
- Original Taste lists 10.6 g sugars per 100 ml; Zero Sugar Caffeine Free lists 0 g and is labelled caffeine-free.
- The specified caffeine-free recipe contains aspartame and acesulfame K and carries a source-of-phenylalanine statement.
Pepsi
Pepsi UK distinguishes regular Pepsi, Pepsi Max and Pepsi Max Caffeine-Free.
- Regular Pepsi lists 4.5 g sugars per 100 ml; Pepsi Max and Pepsi Max Caffeine-Free each list 0 g.
- Standard Pepsi Max contains caffeine. The specified caffeine-free recipe contains aspartame and acesulfame K.
Tesco
Tesco Groceries lists own-label diet cola in cans and 2-litre bottles, including a caffeine-free 2-litre recipe.
- Its listed diet colas have less than 0.1 g sugars per 100 ml; the caffeine-free bottle is labelled accordingly.
- The listed 2-litre bottles should be consumed within 3 days once opened. Standard Tesco Diet Cola contains caffeine.
RC Cola
RC Cola International identifies RC Cola as part of its carbonated-drinks range.
- For a particular UK pack, compare its own nutrition, ingredients and caffeine information rather than applying another country’s recipe details.

Frequently asked questions
Does zero sugar mean caffeine-free?
No. Pepsi UK lists 0 g sugars per 100 ml for Pepsi Max but includes caffeine in its ingredients. If you want neither, look for an explicitly caffeine-free product such as Pepsi Max Caffeine-Free and check the exact pack.
What if I need to avoid phenylalanine?
Check the ingredients and warning on the exact cola. The specified Coca-Cola Zero Sugar Caffeine Free, Pepsi Max and Pepsi Max Caffeine-Free products contain aspartame and carry a source-of-phenylalanine statement; a zero-sugar label alone does not tell you which sweeteners are used.
How soon should a 2-litre cola bottle be finished?
Tesco Groceries instructs customers to consume its listed 2-litre Diet Cola and Caffeine Free Diet Cola within 3 days of opening. Check the instructions on any other bottle rather than assuming it has the same period.
Should a student flat buy cans or a large bottle?
A large bottle suits a group expecting to finish it within the pack’s stated opened-life period. Separately sealed cans suit people drinking at different times; compare the total volume and the space each format needs.
How much sugar is in regular cola?
It depends on the recipe. The Coca-Cola Company lists 10.6 g sugars per 100 ml for Original Taste, while Pepsi UK lists 4.5 g per 100 ml for regular Pepsi. Compare the exact label and the volume you intend to drink.
