Who is this choice for?

Certification-first vegan buyers

If a third party’s vegan checks are essential, look for the Vegan Society Trademark on the current carton rather than relying on the word “soya” or a general plant-based description.

Unsweetened packed-lunch buyers

If you want soya drink for cereal, tea or coffee as well as drinking on its own, compare sugars per 100ml and check whether an opened carton can be kept in a fridge at work.

Own-brand shoppers

If you are considering a supermarket carton, check its storage instructions, fortification and exact-pack vegan labelling separately. An own-brand or unsweetened description does not establish third-party certification.

What should you check before buying?

Start with how the carton will be stored at work, then check the level of vegan assurance you require and the label details that matter for your lunch.

Priority What to check Your needs
Vegan assurance Look for the Vegan Society Trademark on the current pack if you require its third-party checks of ingredients and manufacturing. The Vegan Society says not every vegan-friendly product carries its Trademark. I want confirmation beyond a plant-based description, so I’ll check the exact carton before buying.
Storage at work Check that the unopened carton permits ambient storage. Read its instructions for refrigeration and the use-within period after opening; Sainsbury’s specifies refrigeration and use within three days for its Unsweetened Long Life Soya Drink. My lunch may sit away from a fridge before I open it. If I plan to keep a larger carton for later, I’ll need somewhere to refrigerate it.
Sugars and flavour Compare “of which sugars” per 100ml on the exact cartons, alongside whether they are unsweetened or flavoured. Sainsbury’s lists less than 0.5g sugars per 100ml for its Unsweetened Long Life Soya Drink. For tea or cereal, I may prefer an unsweetened carton; for a drink on its own, I’ll choose the flavour I want after reading the nutrition panel.
Fortification and allergens Read the carton for added nutrients and the ingredient and allergen declaration. Sainsbury’s lists calcium, iodine, vitamin D and B12 for its Unsweetened Long Life Soya Drink. The Food Standards Agency identifies soya as an allergen. I want to know what has been added to the drink. If I have a soya allergy, a vegan or dairy-free label does not make a soya drink suitable for me.

What can catch you out?

  • Assuming every soya drink is third-party vegan-certified

    The Vegan Society distinguishes vegan-friendly products from products carrying its Trademark, which indicates that its team has checked ingredients and manufacturing processes.

    If that certification is a condition of your purchase, look for the Trademark on the current pack rather than treating “soya” or “plant-based” as equivalent.

  • Choosing by flavour without checking sugars

    An unsweetened and a flavoured soya drink may not fit the same intended use; the flavour name alone does not tell you the sugars per 100ml.

    Compare the nutrition panels on the same per-100ml basis, then decide whether the carton is for tea, cereal or drinking on its own.

  • Leaving an opened long-life carton on the desk

    Long-life storage instructions for an unopened carton do not apply indefinitely after opening. Sainsbury’s instructs buyers to refrigerate its Unsweetened Long Life Soya Drink and use it within three days of opening.

    Check your carton’s instructions and whether you have fridge access before opening a large pack at work.

  • Overlooking the soya allergen

    The Food Standards Agency identifies soya as a possible risk for people with a soya allergy. Vegan suitability does not change the drink’s soya content.

    If you have a soya allergy, avoid soya drinks and check the ingredients and allergen information when choosing an alternative.

Brand and retailer references

These examples show why it matters to check the particular carton: vegan labelling, fortification and storage instructions are product-specific.

Alpro

Its long-life soya range includes a No Sugars option for buyers considering an unopened UHT carton for work.

  • Sainsbury’s describes Alpro Soya No Sugar Long Life as UHT, suitable for vegans and made with added calcium, iodine and vitamins B2, B12 and D2.
  • A retailer’s vegan-suitability statement is not the same as confirming a Vegan Society Trademark on the particular carton you buy.

ASDA

Its named chilled and long-life soya milks provide own-brand options for buyers checking Vegan Society Trademark status.

  • The Vegan Society named ASDA Sweetened and Unsweetened Chilled and Long Life soya milks among its Trademark products in July 2026.
  • Check the current pack for the mark, nutrition details and the storage instructions of the variant you choose.

Sainsbury's

Its Unsweetened Long Life Soya Drink is an own-brand UHT option with stated fortification.

  • Sainsbury’s lists calcium, iodine, vitamin D and B12, less than 0.5g sugars per 100ml, and refrigeration with use within three days after opening.
  • If Vegan Society Trademark certification is essential, check the current carton rather than inferring it from the product description.

Tesco

Tesco Groceries lists own-label sweetened and unsweetened long-life soya drinks alongside other brands.

  • The category listing provides more than one long-life formulation to inspect for your preferred flavour and label details.
  • A category listing does not establish third-party vegan certification for each carton; check the exact product label.

Waitrose

Its vegan dairy-alternatives listing includes Essential Unsweetened Soya Drink and Alpro Soya Long Life No Sugar.

  • Waitrose describes the listed Alpro No Sugar drink as UHT and suitable for vegans.
  • Check the selected carton’s certification and storage instructions rather than applying one listing’s details to another product.

Frequently asked questions

Can I put a long-life soya drink in an office packed lunch?

Yes, if the particular carton permits ambient storage while unopened. Once you open it, follow its refrigeration and use-within instructions; Sainsbury’s specifies refrigeration and use within three days for its Unsweetened Long Life Soya Drink.

Does “plant-based” mean a soya drink is vegan-certified?

No. The Vegan Society says its Trademark indicates that its team has checked the product’s ingredients and manufacturing process, while not all vegan-friendly products carry that mark. Check the current carton if this certification is required.

How do I choose between unsweetened and flavoured soya drink?

Choose according to how you will use it, then compare “of which sugars” per 100ml on the cartons rather than relying on their flavour names. For a specific reference point, Sainsbury’s lists less than 0.5g sugars per 100ml for its Unsweetened Long Life Soya Drink.

Is vegan soya drink suitable for someone with a soya allergy?

No. The Food Standards Agency identifies soya as an allergen and a possible risk for people allergic to it. Vegan or dairy-free labelling does not remove the soya allergen.
