Choose sealed long-life soya cartons if you want to buy drinks ahead of a family picnic and the pack permits ambient storage before opening. Several smaller cartons can be easier to portion than one large opened container, but every opened carton needs to be handled according to its own storage instructions. For children aged 1+, NHS guidance refers specifically to unsweetened, calcium-fortified milk alternatives as part of a balanced diet; check the exact drink and never serve soya to someone with a soya allergy.
Sealed, long-life cartons can be bought ahead when their labels permit ambient storage. Think about how many people will share each carton: once it is opened, follow its refrigeration instructions. The Food Standards Agency says picnic foods normally kept in the fridge also need to stay cool.
The NHS says children can have unsweetened, calcium-fortified milk alternatives, including soya drinks, from age 1 as part of a balanced diet. If dairy is excluded regularly, compare the exact carton’s fortification and follow any individual allergy or dietary advice.
Unsweetened, no-sugars and sweetened soya drinks are different recipes. Read the ingredients and the ‘of which sugars’ figure per 100ml on the carton you intend to take, rather than relying on a general plant-based description.
Start with how the cartons will be stored and served, then compare the recipe and allergen label for everyone who will drink them.
| Priority | What to check | Your needs |
|---|---|---|
| Storage | Look for a long-life or UHT carton whose label permits ambient storage before opening. Read its separate refrigeration and use instructions for after opening. | I want to buy the drinks ahead without using cool-bag space for unopened cartons. Any carton we open will need somewhere suitable to be kept afterwards. |
| Carton size | Count servings as well as cartons. Decide whether a shared 1L carton or individual portions fit the group, and open only what you expect to use. | For a group lunch, I may want several sealed cartons rather than opening more drink than we can serve or refrigerate. |
| Fortification | For regular use as a dairy alternative, compare calcium and iodine declarations on the exact pack, alongside any listed vitamins. The NHS specifies unsweetened, calcium-fortified alternatives for children from age 1; recipes vary. | If a child aged 1+ or a dairy-free family member drinks soya regularly, I need to check the actual recipe rather than assume every carton has the same added nutrients. |
| Sugar and flavour | Compare unsweetened and sweetened recipes using ingredients and ‘of which sugars’ per 100ml. Check flavoured drinks separately. | We may prefer a particular flavour, but if limiting sugar matters to us, I want to compare the figures before choosing. |
| Allergens | Check the current ingredient and allergen statement for every carton, including any ‘may contain’ warning. The Food Standards Agency identifies soya as an allergen. | Everyone being served needs a suitable drink. I would not offer a soya drink to a guest with a soya allergy. |
Ambient storage applies to an unopened carton when its label says so. ASDA’s Just Essentials soya drink, for example, instructs shoppers to refrigerate it after opening and use it within four days.
Plan how many cartons to open at the picnic, and read the storage instructions before deciding what to do with any remainder.
An opened remainder needs refrigerated storage and may otherwise go to waste.
Added nutrients differ between products. Tesco Groceries lists calcium, potassium iodide and vitamins in its unsweetened long-life soya drink; that ingredient list does not describe every soya carton.
If the drink will be a regular dairy alternative, compare the exact pack’s calcium, iodine and vitamin declarations. For children aged 1+, keep the NHS guidance on unsweetened, calcium-fortified alternatives in mind.
Sweetened and no-sugars drinks are separate recipes. A plant-based or dairy-free label does not tell you the sugar quantity.
Compare ‘of which sugars’ per 100ml and the ingredients on the particular flavour and pack size you are buying.
Soya drinks contain soya, and some products carry additional warnings: ASDA’s Plant Based Soya Unsweetened listing says it may contain nuts.
Check the current carton before serving, keep its allergen information available and serve an appropriate alternative to anyone who cannot have soya.
Compare specific cartons rather than assuming that every recipe from one brand has the same storage instructions or added nutrients.
Alpro has long-life soya drinks in standard and Organic No Sugars versions, as well as a separately labelled growing-up drink.
Tesco Groceries lists unsweetened and sweetened long-life soya drinks in 1L cartons.
Sainsbury's lists unsweetened and sweetened long-life soya drinks, alongside a separately labelled 1+ Years product.
ASDA lists both an ambient Just Essentials Unsweetened Soya Drink and a separate Plant Based Soya Unsweetened product.
M&S describes its Plant Kitchen Soya Drink as sweetened and also lists a separate unsweetened soya drink.
These options include a multi-carton long-life drink and soya drinks in individual portions. Compare the stated pack sizes with the number of people you are serving, and check each carton’s storage, nutrition and allergen label before relying on it for the picnic.

Eight separate 1L cartons offer a supply that can stay sealed until needed. Follow the pack’s instructions for storage before and after opening, and check its nutrient label if this will be a regular dairy alternative. Contains soya.
No image available
Six individual cartons suit a picnic where drinks will be handed out separately. This malted recipe contains soya and barley; check the sugar figure and the pack’s instructions for storage before and after opening.
No image available
The individually sized cartons suit a larger group or more than one outing, provided the storage instructions fit your plans. Contains soya; compare the pack’s sugar and calcium information if either affects your choice.
No image available
Six individual cartons provide separate servings without opening a shared 1L carton. This is an original sweetened recipe containing soya; read its sugar figure, storage directions and nutrient label for the exact pack.
No image available
Three individual cartons may fit a smaller group without opening a large shared drink. Contains soya; check the exact pack for its sugar, nutrient and storage details rather than assuming they match another Vitasoy pack.
Yes, if the carton’s own label permits ambient storage before opening. Once opened, follow its refrigeration instructions. The Food Standards Agency says foods you would normally keep in the fridge still need to be kept cool at a picnic.
The NHS says children can have unsweetened, calcium-fortified milk alternatives, including soya drinks, from age 1 as part of a balanced diet. Check product-specific age wording too: Sainsbury's says its unsweetened soya drink is not suitable as a main milk-drink alternative for children under 2.
An organic label does not establish the nutrient content. Compare calcium, iodine and vitamin declarations on the exact carton rather than assuming an Alpro Organic No Sugars drink matches the separately listed Alpro No Sugars recipe.
No. Soya drink contains soya, which the Food Standards Agency identifies as an allergen. Check every carton’s current allergen statement for other warnings as well; ASDA’s Plant Based Soya Unsweetened listing, for example, says it may contain nuts.
Keep foods normally stored in the fridge cool until they are ready to eat, as the Food Standards Agency advises for picnics. Food Standards Scotland advises eating ready-to-eat foods within four hours of taking them from the fridge; that advice concerns chilled foods, not unopened ambient cartons.
