Occasional second-home visitors
If the property sits empty between visits, check how to store unopened cola and whether a large bottle is likely to be finished after opening.
Who is this for?
Cola drinkers checking sugar content
If you want to replace regular cola, compare the sugars value on the nutrition panel as well as wording such as no added sugar or zero sugar.
Households stocking for guests who avoid caffeine
Choose a product explicitly labelled caffeine-free. A standard zero-sugar cola may still contain caffeine.
What should you check before buying?
Start with the sugar and caffeine requirements, then choose a pack size that fits how often the property is occupied. Check the exact pack before storing or serving it.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars | Read “of which sugars” per 100ml on the exact pack; compare it with any no-added-sugar or zero-sugar wording. ASDA Groceries lists 0g sugars per 100ml for standard Coca-Cola Zero Sugar and Pepsi Max. | I want the nutrition value to meet my household’s requirement, rather than relying on the front-of-pack wording alone. |
| Caffeine | Look for an explicit caffeine-free label. ASDA Groceries lists Coca-Cola Zero Sugar Zero Caffeine as caffeine-free, while its standard Coca-Cola Zero Sugar and Pepsi Max listings contain caffeine. | If guests avoid caffeine, I need a bottle or can that clearly says it is caffeine-free. |
| Storage and pack size | Check the best-before date and unopened storage directions. For opened 2-litre bottles, follow the product’s refrigeration and use-by-opening instructions; Tesco Groceries and Sainsbury’s each specify use within three days for their listed own-label colas. | For short visits, I would rather leave portions sealed than open a large bottle just before the property becomes vacant. |
| Sweeteners | Read the current ingredient list and any phenylalanine warning. The selected branded and own-label recipes list different sweeteners, so do not assume their ingredients match. | When stocking for several people, I want to check the ingredients of the particular cola they will drink. |
Common stocking mistakes
-
Equating “no added sugar” with a particular sugars value
The claim wording does not tell you the exact sugars figure for that product.
Read “of which sugars” on the nutrition panel if you require a specific value.
-
Assuming zero-sugar cola is caffeine-free
The standard Coca-Cola Zero Sugar and Pepsi Max products listed by ASDA Groceries contain caffeine.
Choose a pack explicitly labelled caffeine-free, and distinguish it from caffeinated bottles if you stock both.
-
Opening a 2-litre bottle before leaving
Tesco Groceries and Sainsbury’s instruct shoppers to refrigerate their listed own-label colas after opening and use them within three days.
Leave a large bottle sealed until it is likely to be used, or consider smaller portions for a brief visit.
An unfinished open bottle may be wasted when the property is left vacant.
-
Assuming every no-sugar cola uses the same sweeteners
The selected branded examples list aspartame and carry phenylalanine warnings; the selected Tesco, Sainsbury’s and ASDA own-label examples list acesulfame K and sucralose.
Check the ingredients and warnings on the pack you buy, particularly when stocking for someone with an ingredient restriction.
Cola brands and own-label options
These examples show why the exact variant matters: a zero-sugar name alone does not settle caffeine content, sweeteners or opened-bottle storage.
Coca-Cola
ASDA Groceries lists both standard Coca-Cola Zero Sugar and a separate Zero Sugar Zero Caffeine 2-litre bottle.
- The listed standard Zero Sugar product reports 0g sugars per 100ml; the Zero Caffeine variant is labelled zero-sugar and caffeine-free.
- Check the exact variant and its ingredients: the selected products list sweeteners including aspartame and carry a phenylalanine warning.
Pepsi
The selected standard Pepsi Max 2-litre listing offers a branded no-sugar option when caffeine is acceptable.
- ASDA Groceries lists 0g sugars per 100ml for the selected standard Pepsi Max bottle.
- That bottle contains caffeine and carries a phenylalanine warning. Check the label of any caffeine-free variant separately.
Tesco
Tesco Diet Cola is an own-label no-added-sugar option in a 2-litre bottle.
- Tesco Groceries lists less than 0.1g sugars per 100ml and instructs shoppers to use the cola within three days of opening.
- The listed recipe contains caffeine and the sweeteners acesulfame K and sucralose.
Sainsbury’s
Sainsbury’s Cola Zero is another own-label 2-litre option to compare for occasional visits.
- Sainsbury’s lists less than 0.5g sugars per 100ml and says to refrigerate after opening and use within three days.
- The listed ingredients include caffeine, acesulfame K and sucralose.
ASDA
ASDA Cola Zero provides an own-label 2-litre bottle for comparing ingredients and nutrition values.
- ASDA Groceries lists less than 0.5g sugars per 100ml for the selected Cola Zero bottle.
- Its listed recipe contains caffeine, acesulfame K and sucralose; choose an explicitly caffeine-free product if that is required.

Frequently asked questions
Does “no added sugar” mean a cola contains no sugar?
Not necessarily: check “of which sugars” on the product’s nutrition panel. Tesco Groceries labels its Diet Cola no added sugar and lists less than 0.1g sugars per 100ml, while ASDA Groceries lists 0g sugars per 100ml for its selected standard Coca-Cola Zero Sugar and Pepsi Max bottles.
What should I stock for visitors who avoid caffeine?
Choose a cola explicitly labelled caffeine-free. ASDA Groceries lists Coca-Cola Zero Sugar Zero Caffeine as a zero-sugar, caffeine-free 2-litre option; its selected standard Coca-Cola Zero Sugar and Pepsi Max products contain caffeine, as do the listed Tesco, Sainsbury’s and ASDA own-label examples.
How should I store unopened cola at a second home?
Follow the directions on the exact bottle and check its best-before date. The selected Coca-Cola Zero Sugar listing calls for cool, dry storage away from direct sunlight, while Tesco’s Diet Cola directions say to keep it cool and out of sunlight.
Will an opened 2-litre bottle suit a short visit?
Check its post-opening instructions before choosing the pack size. Tesco Groceries and Sainsbury’s say to refrigerate their listed own-label colas after opening and use them within three days; individual cans avoid opening a shared bottle when only a few portions are needed.
What if someone needs to check aspartame or phenylalanine labelling?
Read the ingredients and warnings on the exact pack. The selected standard Coca-Cola Zero Sugar and Pepsi Max examples list aspartame and carry phenylalanine warnings, whereas the selected Tesco, Sainsbury’s and ASDA own-label examples list acesulfame K and sucralose. Recheck the pack rather than assuming a recipe has stayed the same.
