Picnic planners packing unopened cartons
A long-life carton can be packed before departure when its label permits ambient storage before opening. You will still need to follow its refrigeration instructions once it is opened.
Who is this for?
Shoppers comparing sugar formulations
Original, unsweetened and no-sugars soya drinks need not have the same nutrition information. Compare the current labels rather than relying on the product names alone.
Hosts serving guests with allergies
Vegan suitability and allergen suitability are separate questions. Check the ingredients and precautionary statements for each guest’s relevant allergens; soya itself is an allergen.
What should you check?
Start with the carton’s vegan and storage information, then compare formulations and any allergen requirements for the people you are serving.
| Priority | What to check | Your needs |
|---|---|---|
| Vegan suitability | Check the exact carton’s vegan statement, ingredients and any Vegan Trademark logo. The Vegan Society says its trademark is neither an allergen nor an environmental certification. | I want a clear basis for choosing a drink for a vegan lunch, without assuming that a plant-based description answers every other label question. |
| Picnic storage | Confirm whether the unopened carton may be stored ambient. Read its separate refrigeration and use-within instructions for after opening; these differ between the Alpro and M&S products described by Waitrose & Partners and Marks & Spencer. | If the carton will be opened at the picnic, I need a plan for chilling any remainder rather than leaving it in the picnic bag. |
| Sugars and added nutrients | Compare sugars on the same per-100 ml or per-100 g label basis. Check the exact formulation for added calcium, iodine and vitamins rather than treating all soya drinks as interchangeable. | I may prefer a no-sugars formulation, or I may want to compare what the original and unsweetened cartons actually list. |
| Organic sourcing | Check whether the particular variant states that its soya is organically grown. Organic wording does not answer the separate vegan, allergen or storage questions. | If organic ingredients matter to me, I can compare that variant without assuming it meets an unrelated requirement. |
| Allergens | Check the current ingredients, highlighted allergens, precautionary statements and any claim concerning the specific allergen at issue. GOV.UK identifies soya beans as an allergen that must be declared when used as an ingredient in prepacked food. | I need to check each guest’s relevant allergens, not use a vegan label as an allergy guarantee. In a Food Standards Agency online survey conducted in December 2023 among adults aged 16–75 in England, Wales and Northern Ireland, 53% of respondents with a food hypersensitivity and 50% of those shopping for someone with one were already aware that vegan products might be unsuitable because of cross-contamination. Those figures measure awareness, not picnic buying preferences. |
Picnic packing mistakes to avoid
-
Treating “vegan” as an allergy guarantee
GOV.UK warns that a vegan label does not guarantee the absence of animal-origin ingredients introduced through cross-contamination. Soya drink also contains soya, which may be the allergen a guest needs to avoid.
Read the current ingredients and precautionary statements for the relevant allergens. Look for a claim concerning a particular allergen when that assurance is needed; do not substitute vegan wording for it.
-
Leaving an opened long-life carton unchilled
Long-life storage instructions for an unopened carton do not apply after opening. The Alpro cartons described by Waitrose & Partners specify refrigeration and use within five days; the M&S products described by Marks & Spencer specify refrigeration and use within three days.
Pack an unopened carton where possible. If you open it, follow that carton’s temperature and use-within instructions for any remainder.
-
Assuming “unsweetened” settles the nutrition comparison
Waitrose & Partners lists 0 g sugars per 100 ml for Alpro No Sugars, while Marks & Spencer lists 0.4 g sugars per 100 g for its unsweetened soya drink. The figures use different stated label bases.
Read each current nutrition panel and compare like-for-like units before choosing a formulation.
-
Reading a vegan logo as a sustainability rating
The Vegan Society states that its Vegan Trademark is not an environmental or eco certification.
If environmental credentials affect your choice, assess them separately rather than inferring them from the vegan logo or an organic product name.
Brand and retailer references
These examples help identify formulations to compare; a brand’s inclusion does not establish what is stocked at a particular shop.
Alpro
Waitrose & Partners lists original, no-sugars and organic Alpro long-life soya drinks, giving shoppers distinct formulations to compare.
- The listed No Sugars and Organic No Sugar variants each state 0 g sugars and 3.3 g protein per 100 ml.

Frequently asked questions
Can I take a long-life soya drink to a picnic?
Yes, if the unopened carton’s instructions permit ambient storage. Once it is opened, follow that product’s refrigeration directions: the Alpro long-life cartons described by Waitrose & Partners specify use within five days, while the M&S cartons described by Marks & Spencer specify three days.
Does a vegan label mean the drink is safe for someone with a milk allergy?
No. GOV.UK says vegan labelling does not guarantee that animal-origin ingredients are absent through cross-contamination. For someone with an allergy, check the current ingredients, precautionary statements and any claim concerning that specific allergen.
Does a UK soya drink label have to identify soya as an ingredient allergen?
Yes. GOV.UK lists soya beans among the allergens that must be clearly identified in a prepacked product’s ingredients list when used as an ingredient. Do not serve a soya drink to someone who needs to avoid soya.
What does the Vegan Trademark tell me?
Where the logo appears on the exact product, it identifies certification under The Vegan Society’s standards concerning animal-derived ingredients. The Society states that the mark is not an allergen or environmental certification, so those questions require separate checks.
Should I buy original, no-sugars or organic soya drink?
Choose according to the distinction that matters to you: compare original with no-sugars formulations on their current nutrition panels, and consider an organic variant if its ingredient sourcing is a priority. For a picnic, whichever you choose must also have suitable unopened storage instructions, and its vegan and allergen information must meet the needs of those drinking it.
