Households choosing an everyday cola
If cola will be kept on hand regularly, compare the sugars per 100ml of the exact sweetened, diet and zero-sugar variants rather than assuming they have similar formulations.
Who is stocking the pantry?
Homes looking for a caffeine-free option
A zero-sugar label does not establish that a cola is caffeine-free. Pepsi UK lists Pepsi Max No Caffeine, and Tesco Groceries lists Caffeine Free Diet Cola, as options that address both requirements.
Shoppers considering larger bottles
A 2L bottle may suit shared servings, but check how quickly it will be finished. The Tesco and Sainsbury’s 2L examples specify use within three days of opening; compare the current price per litre with the cans you would otherwise buy.
What should you check before buying?
Decide on sugar and caffeine first, then choose a pack size that fits how the household will use and store the cola.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar and energy | Compare sugars and energy per 100ml on the exact variant; check the serving size if comparing cans with a multi-serve bottle. Coca-Cola GB lists Original Taste at 10.6g sugars and 42 kcal per 100ml, while Pepsi UK lists Pepsi Classic at 4.5g sugars and 18 kcal per 100ml. | I want to know whether I am buying a conventional sweetened cola or a zero-sugar version, rather than judging by the brand or bottle size. |
| Caffeine and sweeteners | Read the caffeine and sweetener declarations on each pack. Pepsi UK lists caffeine in Pepsi Max but offers Pepsi Max No Caffeine; its Pepsi Max ingredient information also includes a phenylalanine statement. | Some people drinking the pantry supply want to avoid caffeine, so a zero-sugar label alone will not settle the choice. |
| Pack format | Check the number and size of servings, plus opened-pack storage. Tesco Groceries and Sainsbury’s specify use within three days of opening for the cited 2L colas; Sainsbury’s also instructs refrigeration after opening. | Will we finish a large bottle within the time stated on its label, or would individual cans fit how we serve cola at home? |
| Own-label options | Compare the exact variant’s sugars per 100ml and ingredients, then check the current price per litre for the pack size. Sainsbury’s lists 4.3g sugars per 100ml for its Cola and less than 0.5g for its Cola Zero. | I am open to a supermarket cola, but I do not want to assume its standard and zero-sugar bottles contain the same ingredients. |
What is easy to overlook?
-
Assuming every 2L cola is low in sugar
Sainsbury’s lists 4.3g sugars per 100ml for its standard Cola, compared with less than 0.5g per 100ml for Cola Zero. Bottle size does not identify the formulation.
Check sugars per 100ml and the ingredients of the exact variant before buying several bottles.
-
Buying a bottle that will stay open too long
The cited Tesco and Sainsbury’s 2L colas instruct shoppers to use the bottle within three days of opening.
If the household is unlikely to finish it within the time on the pack, consider individual cans or a smaller bottle.
-
Treating zero sugar as a complete suitability check
Pepsi Max contains caffeine, while Pepsi Max No Caffeine is a separate variant. Sweeteners and phenylalanine statements also need checking on the relevant pack.
Read the sugar, caffeine and ingredient information for the precise cola that household members will drink.
Which brand ranges are relevant?
These ranges illustrate different formulations and pack choices; a brand name alone does not establish the ingredients of a particular variant.
Coca-Cola
Coca-Cola GB lists Original Taste alongside Zero Sugar and Zero Sugar Zero Caffeine variants.
- Coca-Cola GB lists Original Taste at 10.6g sugars and 42 kcal per 100ml.
- Check the variant label: its sugar and caffeine information differs across the range.
Pepsi
Pepsi UK lists Classic, Max and Max No Caffeine as distinct cola options.
- Pepsi UK lists 4.5g sugars per 100ml for Classic and 0g per 100ml for Max and Max No Caffeine.
- Pepsi Max contains caffeine; choose the specifically labelled No Caffeine variant if that distinction matters.
Tesco
Tesco Groceries lists 2L Diet Cola and Caffeine Free Diet Cola as separate own-label variants.
- Both cited bottles list less than 0.1g sugars per 100ml; the caffeine-free version is identified separately.
- Both cited bottles instruct use within three days of opening.
Sainsbury’s
Sainsbury’s lists standard Cola and Cola Zero in 2L bottles.
- The cited Cola lists 4.3g sugars per 100ml; Cola Zero lists less than 0.5g per 100ml.
- Both cited variants contain caffeine and instruct refrigeration and use within three days after opening.

Frequently asked questions
Does zero-sugar cola also mean caffeine-free?
No. Pepsi UK lists caffeine in Pepsi Max, while Pepsi Max No Caffeine is a separate zero-sugar variant. Tesco Groceries likewise distinguishes its Diet Cola from Caffeine Free Diet Cola. Check the exact pack’s ingredients.
How long can a 2L cola bottle be kept after opening?
Tesco Groceries and Sainsbury’s instruct shoppers to use the cited 2L colas within three days of opening; Sainsbury’s also specifies refrigeration after opening. Follow the instructions on the bottle you buy.
Is a retailer listing enough to check ingredients?
Use the listing to compare products while shopping, then read the physical pack’s ingredients and relevant statements before consuming. Check the precise variant, particularly when caffeine, sweeteners or a phenylalanine statement matter to your choice.
