Who is this choice for?

The key distinction is whether the person drinking the soya milk needs gluten-free reassurance, particular nutrition-label information, or a carton size that fits how often they use it.

People following a gluten-free diet

If gluten avoidance is necessary, choose by the exact carton, not the fact that the drink is soya-based. Coeliac UK advises checking the ingredients and precautionary allergen wording when a product has no gluten-free claim.

Family members and household shoppers

When buying for someone else, confirm their gluten and soya requirements before choosing a variant. Check whether the household can refrigerate an opened carton and finish it within the period on its label.

Shoppers comparing unsweetened drinks

A no-sugars or unsweetened label answers a different question from a gluten-free claim. Check both statements on the exact variant if both matter to the person who will drink it.

What should you check?

Check gluten-related wording on the exact carton first. Then compare nutrition and storage details that matter to the household, without treating one label claim as proof of another.

Priority What to check Your needs
Gluten-free claim Look for the words “gluten free” on the specific carton. Coeliac UK explains that the claim applies to food containing no more than 20 parts per million of gluten. I need clear gluten-free wording on the drink I am actually buying, rather than an assumption based on soya as an ingredient.
Ingredients and warnings Read the highlighted allergens and any precautionary statement. Coeliac UK advises checking for precautionary allergen labelling when soya milk has no gluten-free claim. If my usual carton has changed, I want to check its current label before buying it again for someone who avoids gluten.
Sugars Compare sugars on the nutrition panels using the same per-100 ml basis. Check a gluten-free claim separately from “no sugars” or “unsweetened”. I may want an unsweetened drink, but that wording alone does not settle my gluten-free choice.
Nutrients If using the drink as a regular dairy alternative, compare the exact variants’ listed protein and added calcium, vitamin D, vitamin B12 and iodine. Ingredients and fortification differ between products. When choosing a repeat household purchase, I want to compare the nutrients shown on the cartons rather than assume all soya drinks have the same recipe.
Storage Distinguish chilled from UHT cartons before opening, then follow each product’s refrigeration and use-within instructions after opening. The checked Alpro No Sugar chilled listing says five days; Waitrose Essential and M&S unsweetened listings say three days. If only a little soya drink is used each day, I need a quantity the household can finish within the opened carton’s labelled period.
Soya allergen Check the soya allergen declaration independently of any gluten-free statement. When shopping for another person, I need to confirm that soya itself is suitable for them.

Common buying mistakes

  • Treating “plant-based” or “unsweetened” as a gluten-free claim

    Those descriptions do not answer whether the finished drink meets a gluten-free requirement.

    Look for gluten-free wording on the specific carton. If it has no claim, follow Coeliac UK’s advice to inspect the ingredients and precautionary allergen labelling.

  • Choosing an own-label carton by price alone

    The checked Waitrose Essential and M&S online listings describe unsweetened soya drinks, but do not display an explicit gluten-free claim. A comparison of other product details cannot establish that claim.

    Check the current pack for gluten-related wording before comparing its sugars, nutrients or storage instructions with another variant.

  • Overlooking the period after opening

    A long-life carton’s storage instructions before opening do not tell you how long to keep it once opened. The checked product listings give different post-opening periods.

    Read the use-within instruction and choose a carton quantity the household can realistically finish in that time.

  • Forgetting that gluten and soya are different allergens

    A gluten-free claim does not remove soya from a soya drink.

    When buying for another person, check their soya requirements as well as the carton’s gluten-related information.

Brand and retailer references

The label evidence here concerns particular drinks and retailer information, not every product sold under each name. Check the variant and current carton when making a repeat purchase.

Alpro

Alpro UK and the checked retailer listings state “gluten free” for specific Soya Original, No Sugar chilled and Organic long-life variants.

  • These named variants offer an explicit claim to look for when gluten-free wording is the first selection criterion.
  • The claim for one variant does not establish the status of every Alpro drink; check the carton being purchased.

Waitrose Essential

Waitrose lists an unsweetened UHT soya drink with added calcium, vitamin D, vitamin B12, vitamin B2 and iodine.

  • Its listing provides fortification and post-opening storage details for comparing the exact product.
  • The checked online listing does not display an explicit gluten-free claim; inspect the current carton for gluten-related wording.

M&S Plant Kitchen

M&S lists an unsweetened soya drink with added calcium, iodine, vitamin D and vitamin B12.

  • The product listing gives ingredients and storage information to check against household needs.
  • The checked online page does not state that this drink is gluten free; check the physical carton.

Tesco

Tesco’s checked Alpro Organic long-life product listing states “gluten free” and “suitable for coeliacs”.

  • The specific Alpro listing gives shoppers an explicit claim to compare with the current carton.
  • A gluten-free browse category does not establish the status of every Tesco own-label soya drink.

Sainsbury's

Sainsbury's provides allergen information for its own-brand products and advises shoppers to check packaging because ingredients can change.

  • Its packaging advice is useful when checking a repeat household purchase.
  • Do not treat general allergen guidance as a gluten-free claim for a particular own-label soya drink.

Alpro Plant Protein 1L soya drink

Alpro Plant Protein 1L

Alpro Soya Drink OG 1L

The product description describes this OG variant as a UHT soya drink with a gluten-free claim and no sugars listed; check the current carton. It identifies a 1L quantity, but the number of cartons in the order needs confirming before purchase. Contains soya.

Frequently asked questions

Is soya milk automatically gluten free?

No. Coeliac UK includes soya milk among products to check. Look for a gluten-free claim on the specific carton; if there is none, inspect its ingredients and precautionary allergen wording.

What does a “gluten free” statement tell me?

Coeliac UK explains that food labelled “gluten free” must contain no more than 20 parts per million of gluten. The statement does not, by itself, tell you that the carton carries a separate certification logo.

How do I check an own-label drink without an online gluten-free claim?

Read the current physical carton. Check for a gluten-free claim, highlighted cereals containing gluten in the ingredients, and any “may contain” or similar precautionary statement. Coeliac UK specifically advises checking precautionary allergen labelling when soya milk has no gluten-free claim.

How long can a soya-drink carton be kept after opening?

Follow the exact carton’s instructions because periods differ. The checked Alpro No Sugar chilled listing says to use it within five days of opening; the Waitrose Essential and M&S unsweetened listings say three days. Refrigerate opened cartons as their labels direct.

Does a gluten-free claim make soya milk suitable for someone with a soya allergy?

No. A gluten-free claim concerns gluten, not soya. Soya drinks contain soya, so check the allergen declaration and the intended drinker’s requirements separately.
