Choose the exact fizzy-drink variant by its sugar content, caffeine status and flavour, rather than assuming that a familiar brand name tells you all three. UK product information from Coca-Cola GB and Pepsi UK shows that some zero-sugar colas contain caffeine, while separately named caffeine-free variants offer a different choice. If a particular attribute or pack size matters, state what substitutions you would accept: Tesco says it tries to follow order notes but cannot guarantee the requested alternative.
If you want a fizzy drink but are comparing regular and zero-sugar versions, read the sugars figure per 100ml for the exact variant. Manufacturer figures differ even among drinks with similar flavours: Pepsi UK lists 4.5g per 100ml for regular Pepsi and 0g for Pepsi MAX.
A zero-sugar name does not settle the caffeine question. Coca-Cola GB lists caffeine flavouring for standard Coca-Cola Zero Sugar, and Pepsi UK lists caffeine for Pepsi MAX; both brands also identify separately named caffeine-free variants.
If regular instead of zero sugar, or caffeinated instead of caffeine-free, would be an unsuitable swap, set a substitution preference when ordering. Tesco says personal shoppers will try to follow notes, although the requested substitute may not be possible.
Start with the attributes you would not want a substitute to change, then choose a flavour and pack format that fit the order.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar | Compare sugars per 100ml on the exact variant, not the total sugar in differently sized packs. Pepsi UK lists 0g per 100ml for Pepsi MAX and 4.5g for regular Pepsi. | I want to distinguish a zero-sugar drink from its regular counterpart without relying on the flavour or brand name alone. |
| Caffeine | Read the variant name and ingredients. Coca-Cola GB and Pepsi UK list caffeine in their standard zero-sugar colas but identify separate caffeine-free versions. | If caffeine is a deciding factor for my household, I need the specifically caffeine-free variant, not just one labelled zero sugar. |
| Flavour | Check whether the drink is cola, lemon-and-lime or a named fruit flavour, then compare that variant’s nutrition. Coca-Cola GB lists 0g sugars per 100ml for Sprite Zero and 0.4g for Fanta Fruit Twist Zero. | Perhaps I want citrus or fruit flavour rather than cola, while still checking the sugar figure for the drink I choose. |
| Substitutions | Set a preference for the attributes that matter, including sugar, caffeine, flavour and pack size. Tesco says order notes may not always be fulfilled. | I would rather specify an acceptable alternative than receive a different variant that does not meet my requirements. |
| Delivery fit | Check the available service and slot for your address, and whether the can count suits your wider grocery order. Tesco describes Whoosh as available only in selected areas. | For a household multipack, I need a delivery option that works for my address and a quantity I can use. |
Standard Coca-Cola Zero Sugar and Pepsi MAX list caffeine, according to their UK product information. A zero-sugar substitution could therefore miss a caffeine-free requirement.
Specify a caffeine-free variant in the order note when that distinction matters, and check the label on any substituted drink.
Regular and zero-sugar versions can have different sugars figures even when their names and flavours are similar. Pepsi UK, for example, lists 4.5g sugars per 100ml for regular Pepsi and 0g for Pepsi MAX.
Make the required sugar status clear in your substitution preference, alongside any flavour or pack-size requirement.
