For a picnic needing at least four pints of soya drink, plan in litres rather than assuming a four-pint pack: Tesco’s four-pint milk label gives 2.272L, so two 1-litre cartons fall short and three provide more than you need. Unopened long-life cartons offer a way to transport the drink before serving, but chilled or opened cartons need cooling. Check the exact pack for storage instructions, ingredients and allergens.
If your serving plan calls for roughly four pints, the number of cartons matters more than finding that wording on a soya-drink pack. Tesco’s four-pint milk label gives 2.272L; the Sainsbury’s, M&S, Waitrose and Alpro soya examples here are 1-litre cartons.
If soya drink will also be a regular dairy alternative, compare sugar values and the stated calcium, iodine, vitamin D and vitamin B12 fortification on the particular carton. Variants need not have the same ingredients or nutrition values.
Check who will drink it before packing. The Food Standards Agency identifies soya as an allergen, while age statements differ between the Sainsbury’s and Waitrose products described here.
Decide how much drink will be served, then match the pack’s unopened and after-opening storage instructions to the journey and picnic.
| Priority | What to check | Your needs |
|---|---|---|
| Quantity | Check the volume on each pack and estimate servings. Tesco labels four pints as 2.272L; two 1-litre cartons give 2L and three give 3L. | Will I serve at least four pints, or would fewer cartons cover the guests without opening more than necessary? |
| Storage | Read the instructions for unopened and opened cartons separately. The Food Standards Agency advises keeping foods normally stored in a fridge cool at a picnic, using a cool bag or box with ice or frozen gel packs. | If the drink is already chilled or opened, I need a way to keep it cool until serving. |
| Ingredients and nutrition | Compare sugar values on the same per-100ml basis and check the listed fortification. The NHS advises fortified dairy alternatives and lower-sugar options for people following a vegan diet. | I’d like an unsweetened option, and I want to know which nutrients are added to the carton I choose. |
| Guest suitability | Read the current allergen declaration and any age guidance on the exact pack. The Food Standards Agency identifies soya as an allergen; Sainsbury’s and Waitrose give product-specific guidance for children under two. | Before I serve it, I need to know whether any guest has a relevant allergy and whether the product is suitable for the children attending. |
The 1-litre soya cartons described by Sainsbury’s, M&S, Waitrose and Alpro do not individually match the 2.272L shown on Tesco’s four-pint milk label. Two cartons would leave a four-pint serving plan short.
Estimate the servings before buying. Choose three 1-litre cartons if you need at least 2.272L and can use or store the remainder according to its pack instructions.
Long-life storage instructions apply before opening. The Sainsbury’s, M&S and Waitrose examples require refrigeration and use within three days after opening; the Alpro example specifies refrigeration and use within five days.
Open cartons as needed, return any opened carton to a cool bag or box promptly, and follow its own temperature and consumption instructions.
Sweetened and unsweetened variants differ, and a dairy-free description alone does not identify the nutrients added to a drink.
For regular use as a dairy alternative, compare the nutrition panel and ingredients on the exact carton. The NHS advises choosing fortified dairy alternatives and lower-sugar options for a vegan diet.
Soya remains an allergen, as identified by the Food Standards Agency. An allergy to dairy and an allergy to soya are different considerations.
Ask guests about allergies and check the current pack’s ingredient and allergen statements before serving.
These retailer listings illustrate pack and storage details to compare; check the particular variant you intend to bring.
Waitrose lists Alpro Soya No Sugars Long Life Drink in a 1-litre UHT carton.
Sainsbury’s lists an unsweetened long-life soya drink in a 1-litre carton.
M&S lists a Plant Kitchen unsweetened soya drink in a 1-litre long-life carton.
Waitrose lists Essential Unsweetened Soya Drink as a 1-litre UHT carton.
This long-life soya-drink bundle suits planning for a larger group or for using unopened cartons later. Its eight 1-litre cartons total 8L, well above Tesco’s 2.272L four-pint reference.

The unopened long-life cartons offer flexibility for a picnic, but this 8L bundle is substantially more than a four-pint serving plan. The product description lists 0.0g sugars per 100ml and added calcium and vitamins B2, B12 and D. After opening, refrigerate at +1°C to +7°C and use within five days; check the current pack for allergen and age information before serving.
Follow the carton’s unopened storage instructions: the listed UHT examples can be stored ambient before opening. An already opened carton needs refrigeration, so pack it in a cool bag or box with ice or frozen gel packs, in line with Food Standards Agency picnic guidance.
Three cartons provide 3L, exceeding the 2.272L shown on Tesco’s four-pint milk label by 728ml. Two cartons provide 2L and fall short by 272ml. Consider how much will actually be served before opening a third carton.
Compare the sugar value per 100ml, the ingredients and any stated fortification on the exact variant. The Sainsbury’s, M&S and Waitrose unsweetened products described here list added calcium, iodine, vitamin D and vitamin B12, but their storage and age instructions are not interchangeable.
No: the Food Standards Agency identifies soya as an allergen. Check guests’ allergies and the current pack before serving; if young children will drink it, check the product’s age statement too, as the listed Sainsbury’s and Waitrose cartons carry specific under-two guidance.
Keep drinks that require refrigeration cool in a cool bag or box with ice or frozen gel packs. The Food Standards Agency’s picnic guidance says that, in extremely hot weather, food that has been out of the fridge should be used within two hours; take items out only when needed.
