Choose flavours the household will drink, then compare the sugar and ingredients on each 2-litre bottle rather than treating every regular or zero-sugar version alike. If caffeine or a phenylalanine notice matters to someone in the household, check the exact variant before stocking up; pack size and storage space also matter when buying several bottles.
If several share-size bottles are going into the trolley, compare the declared sugars per 100ml across the exact variants you want. A zero-sugar name does not answer separate questions about caffeine, sweeteners or label warnings.
When some people want cola and others prefer orange, lemon-and-lime or another fruit flavour, a mix of bottles may be more useful than several of one flavour. Compare the nutrition panel for each choice rather than assuming drinks of the same flavour have the same ingredients.
Settle on the flavours and number of bottles first, then compare nutrition and ingredients on the variants you are considering.
| Priority | What to check | Your needs |
|---|---|---|
| Flavour mix | Check the exact flavour and whether it is regular or zero sugar. Do not assume variants within one brand have the same ingredients. | Different people in my household prefer different drinks, so several bottles of one cola may not suit the whole shop. |
| Sugars | Compare sugars per 100ml, then check the stated serving size against the glass you expect to pour. Pepsi UK lists 0g per 100ml for Pepsi MAX and 4.5g per 100ml for regular Pepsi; Tesco lists 27g per 250ml for Coca-Cola Original Taste. | I want to tell the regular and zero-sugar bottles apart before buying enough for several servings. |
| Caffeine | Read the ingredients on the exact bottle. Pepsi MAX lists caffeine, whereas Pepsi has a separate MAX No Caffeine product line; confirm both the variant and bottle format. | Someone at home needs a drink selected without relying on the words ‘zero sugar’ to mean caffeine free. |
| Sweeteners and warnings | Check the sweeteners and any phenylalanine notice on the label. Pepsi UK lists sweeteners and a source of phenylalanine for Pepsi MAX. | If a label warning matters in our household, I need to check the specific flavour and variant, not just its brand. |
| Bottle quantity | Check both the 2-litre bottle size and the number of bottles in a pack. Plan where a multipack will be stored. | For a large shop, I want enough bottles for the occasion without buying a pack that is awkward to store. |
The figures differ across products: Pepsi UK lists 4.5g sugars per 100ml for regular Pepsi, while Tesco lists 27g per 250ml for Coca-Cola Original Taste. Bottle size alone does not show what is in a poured glass.
Compare sugars per 100ml on the exact bottles, then use the stated serving value or the size of the glass you plan to pour.
Pepsi MAX lists caffeine despite declaring 0g sugars per 100ml. Sweeteners and label warnings are separate checks too.
Read the ingredients and warnings for the chosen variant, particularly when caffeine or a phenylalanine notice matters to someone in the household.
Ingredients and nutrition information can change when a drink is reformulated. An earlier listing may therefore differ from the bottle delivered or picked up in store.
Check the bottle’s ingredients, nutrition table, warnings and best-before date when you receive it.
These examples show why the variant name and label matter; a brand name alone does not establish the sugar or caffeine content of every bottle in its range.
Original Taste and Zero Sugar are distinct cola choices.
The range includes regular Pepsi, Pepsi MAX and a separate Pepsi MAX No Caffeine line.

A six-bottle cola pack for a household choosing a zero-sugar variant. The stated nutrition is 0g sugars per 100ml; the product information also identifies caffeine, sweeteners and a phenylalanine warning. Check the bottles’ labels if those ingredients or warnings matter to your household.

This six-bottle cola pack declares 0g sugars per 100ml and lists sweeteners and a source of phenylalanine. Although the variant is named Caffeine Free, its product information contains conflicting caffeine statements. If avoiding caffeine matters, check the ingredients on the exact bottles before relying on the name.

An eight-bottle pack for a household choosing regular cola and able to store the bottles. Pepsi UK lists 4.5g sugars per 100ml for regular Pepsi; the product information also identifies caffeine and sweeteners. Check the bottle label and the portion you expect to serve.
A 2-litre bottle fills eight 250ml glasses. Tesco uses that serving guide for Coca-Cola Original Taste; the number of glasses will change if you pour different amounts.
No. Pepsi MAX lists caffeine despite declaring 0g sugars per 100ml, and Dr Pepper Zero also lists caffeine. Look for a specifically caffeine-free variant and check its ingredients; Pepsi MAX No Caffeine is a separate product line.
The notice appears on drinks containing aspartame. Pepsi UK lists a source of phenylalanine for Pepsi MAX. If that warning matters to someone in your household, check the label of the exact bottle before serving it.
Not necessarily: choose a mix that reflects the household’s flavour preferences and the portions you expect to pour. Compare sugars per 100ml on each regular and zero-sugar variant, and check caffeine, sweeteners and warnings separately.
Use it to compare options, then read the bottle when it arrives or is picked up. Ingredients and nutrition information can change with reformulation, so the label is the practical check for the drink you will serve.
