Four pints is 2.272L, as shown on Tesco Groceries’ four-pint milk listing; a 1L soya-drink carton is not an exact substitute. For a summer holiday, three 1L cartons provide 3L if that extra volume is useful, but check the sugar content, fortification and storage instructions on the cartons you choose.
If you need soya drink for breakfasts, hot drinks or cooking, plan the total volume and how many cartons you will open at once. The 1L cartons listed by the retailers discussed here are smaller than a four-pint container.
If sugar content matters to your choice, compare the nutrition panels rather than relying on carton colour or a dairy-free label. Tesco Groceries lists different sugars per 100ml for its sweetened and unsweetened 1L drinks.
If a child cannot consume dairy, check the exact drink’s fortification and age guidance. Kingston and Richmond NHS Foundation Trust highlights calcium and iodine fortification, while Sainsbury’s and Waitrose warn that their listed ordinary soya drinks are not suitable as a main milk-drink alternative for children under two.
Start with the amount you need, then compare labels and decide how you will store each carton during the holiday.
| Priority | What to check | Your needs |
|---|---|---|
| Pack volume | Check net contents in litres and the number of cartons. Tesco Groceries labels a four-pint milk pack as 2.272L; three 1L cartons total 3L, not four pints. | I need to know whether the amount must be exactly four pints or whether extra unopened cartons would be useful during the holiday. |
| Sugars and flavour | Compare sugars per 100ml and read the ingredients. Tesco Groceries lists 0.5g per 100ml for its Longlife Unsweetened soya drink and 2.5g per 100ml for its Longlife Sweetened version. | For cereal, drinks or cooking, I want a flavour I will use, with a sugar value that matches what I intended to buy. |
| Fortification and age | Read the exact pack for calcium, iodine and vitamins, then check any age warning. Kingston and Richmond NHS Foundation Trust advises checking calcium and iodine fortification when a child cannot consume dairy. | If this will regularly replace dairy for a child, I need to check the particular drink’s fortification and whether it is suitable for that child’s age. |
| Storage after opening | Check whether the unopened pack permits cupboard storage and follow its refrigeration and use-within instructions after opening. Listed retailer examples specify either three or five days after opening, depending on the product. | Will I have room to refrigerate an opened carton, and can we finish it within its own labelled period? |
| Soya allergen | Check the current ingredients and allergen statement for soya. The Food Standards Agency identifies soybeans among the allergens that UK food businesses must declare when present as an ingredient. | If someone drinking it has a soya allergy, I need a different drink rather than assuming that dairy-free means suitable. |
Tesco Groceries labels its four-pint milk pack as 2.272L. Two 1L cartons fall short of that volume; three provide 3L.
Check net contents and decide whether you need an exact amount or enough unopened cartons to cover several days.
Sweetened and unsweetened versions can have different listed sugars: Tesco Groceries gives 2.5g and 0.5g per 100ml respectively for its two Longlife soya drinks.
Compare the nutrition panel and ingredients on the exact version you intend to buy.
The listed Tesco, Sainsbury’s, M&S and Waitrose examples require refrigeration after opening, with product-specific use-within periods. The Food Standards Agency also advises keeping picnic foods that normally need refrigeration cool.
Arrange chilled storage for an opened carton and follow its own label, particularly during travel or a day out.
An opened carton you cannot keep chilled or finish within its labelled period may go unused.
Sainsbury’s and Waitrose warn that their listed ordinary soya drinks are not suitable as a main milk-drink alternative for children under two. Soya is also an allergen for some people.
Check age guidance and the current allergen statement on the exact pack. For a child who cannot consume dairy, follow appropriate professional dietary advice rather than relying on the dairy-free label alone.
These examples show label details worth comparing; a brand’s inclusion here does not mean every product in its range has the same contents or instructions.
Sainsbury’s lists Alpro Soya Original as a 1L UHT drink.
Tesco Groceries lists 1L Longlife Sweetened and Unsweetened soya drinks.
Sainsbury’s lists an own-brand Unsweetened Soya Drink in a 1L carton.
Marks & Spencer lists a Plant Kitchen Unsweetened Soya Drink in a 1L carton.
Waitrose lists Essential Unsweetened Soya Drink as a 1L UHT option.
These Alpro options are cartons to consider when planning holiday supplies, not single four-pint containers. Check the quantity on the product page before deciding how much to order.

For a holiday stock-up, the named 8 x 1L pack totals 8L, considerably more than the 2.272L four-pint target.
Check whether you can store and use that quantity, and follow the current pack’s instructions after opening.

If you are planning the holiday’s total volume, the title identifies a 1L size, not a single four-pint container.
Confirm the number of cartons and total net volume on the listing before treating the leading “6” in the product title as a pack quantity.
No. Tesco Groceries labels a four-pint milk pack as 2.272L, so two 1L cartons are 0.272L short and three total 3L. Check a soya drink’s own net contents rather than treating its format as an exact four-pint replacement.
It can be convenient to take unopened if its label permits cupboard storage. Once opened, follow that carton’s refrigeration and use-within instructions: the Tesco, Sainsbury’s, M&S and Waitrose examples give different periods.
Keep it cool in a cool bag or box with ice or frozen gel packs if its label requires refrigeration after opening. Food Standards Agency picnic guidance says foods normally kept in the fridge should stay cool and warns that the risk from bacteria increases after four hours or more at 8°C and above.
Do not assume it is suitable for a child under two: Sainsbury’s and Waitrose give warnings for their listed drinks. For a child who cannot consume dairy, Kingston and Richmond NHS Foundation Trust highlights calcium and iodine fortification; check the exact product and seek appropriate dietary advice.
No, a soya drink is not an alternative for someone with a soya allergy. Check the current ingredients and allergen statement when choosing another product; the Food Standards Agency identifies soybeans as an allergen that UK food businesses must declare when present as an ingredient.
