Gluten-free Christmas bakers
Anyone making cakes, buns or desserts for a gluten-free diet needs to check the drink and every other ingredient, rather than relying on a plant-based label.
Who is this for?
Bakers controlling recipe sweetness
If a recipe measures its sugar separately or includes dried fruit and chocolate, the drink’s sugar content is another quantity worth checking.
People planning several bakes
Long-life cartons can fit advance shopping plans. Check the pack size and the carton’s refrigeration and use instructions for the days after opening.
What should you check?
Start with the gluten-free claim, then compare the drink’s sugar content and pack instructions with your recipe and baking schedule.
| Priority | What to check | Your needs |
|---|---|---|
| Gluten-free status | Look for an explicit gluten-free claim on the current carton. UK Food Standards Agency guidance, revised in March 2025, sets the threshold for that label at no more than 20 mg/kg of gluten in the food as sold. Check other recipe ingredients separately. | I’m baking for someone who needs a gluten-free cake, so a dairy-free or plant-based claim on the drink is not enough. |
| Recipe sweetness | Compare sugars per 100 ml with the recipe. Asda Groceries lists 0 g for Alpro Organic Soya No Sugars Long Life and Alpro Soya No Sugar Chilled, versus 2.5 g for Alpro High Protein Soya Original. | When sugar, fruit or chocolate is already measured into my bake, I want to know whether the drink adds sugars too. |
| Recipe fit | Check whether the recipe calls for a dairy-free milk alternative and how much liquid it uses. Alpro describes its soya drinks as suitable for cooking and baking; that is manufacturer guidance, not a comparison of finished bakes. | I’d rather follow a recipe that already allows a dairy-free alternative than assume a substitution will give the same result. |
| Pack and storage | Check the pack quantity and instructions before and after opening. Sainsbury’s lists three days after opening for its Unsweetened Long Life Soya Drink; Asda Groceries lists five days for Alpro Organic Soya No Sugars Long Life. Both specify refrigeration once opened. | If I’m baking on different days, I need a carton size and opening date that fit the plan. |
| Other allergens | Read the specific pack’s allergen statement and warnings. Gluten-free labelling does not remove soya or establish suitability for a different allergy. | I need to account for every guest’s relevant allergens, not just gluten. |
Common buying mistakes
-
Equating plant-based with gluten free
Plant-based and dairy-free labels answer different questions from a gluten-free claim. Under UK Food Standards Agency guidance, a food labelled gluten free must contain no more than 20 mg/kg of gluten as sold.
For a strict gluten-free bake, check the current drink carton for that claim and check every other ingredient separately.
-
Overlooking sugars in the drink
Asda Groceries lists 0 g sugars per 100 ml for its Alpro no-sugars products, but 2.5 g per 100 ml for Alpro High Protein Soya Original. They are not interchangeable if the recipe calls for a particular sweetness.
Compare the drink’s label with the measured sugar and other sweet ingredients before choosing.
-
Planning from the unopened storage format alone
A long-life carton still has a refrigerated use period after opening. Sainsbury’s specifies three days for its Unsweetened Long Life Soya Drink, while Asda Groceries specifies five days for Alpro Organic Soya No Sugars Long Life.
Follow the specific carton’s instructions and note when you opened it.
-
Treating gluten free as free from all allergens
Soya remains relevant to someone with a soya allergy. Marks & Spencer also warns that its Plant Kitchen Soya Drink is unsuitable for people with nut or peanut allergies.
Read the allergen statement and warnings on the product you intend to use before serving it.
Brand and retailer references
These examples show why the claim and instructions on a specific product matter more than the retailer or brand name alone.
Alpro
Asda Groceries lists gluten-free claims for specific Alpro no-sugars and high-protein soya drinks.
- Its listed Organic Soya No Sugars Long Life and Soya No Sugar Chilled drinks have 0 g sugars per 100 ml; High Protein Soya Original has 5.0 g protein and 2.5 g sugars per 100 ml.
- Alpro’s cooking and baking guidance does not establish how these drinks compare in the texture or rise of a Christmas bake. Check the current carton for the variant you buy.
Tesco
Tesco places its own-label sweetened and unsweetened long-life soya drinks in a gluten-free dairy-alternative drinks browse category.
- The range offers a choice between sweetened and unsweetened drinks.
- Check the individual carton for an explicit gluten-free claim and its ingredients before using it for a strict gluten-free bake.
Sainsbury’s
Its Unsweetened Long Life Soya Drink is listed as fortified with calcium, iodine and vitamins D and B12.
- Sainsbury’s instructs customers to refrigerate this drink after opening and use it within three days.
- Check the current carton for a gluten-free claim before selecting it for a strict gluten-free bake.
Asda
Asda Groceries provides gluten-free claims on its product pages for several specific Alpro soya drinks.
- Its listings distinguish no-sugars, chilled and high-protein Alpro variants.
- Those branded product claims do not establish the status of an Asda own-label drink or another Alpro variant.
M&S
The Plant Kitchen Soya Drink listing includes nut and peanut allergy warnings.
- Check both the current gluten-free claim and allergen warnings for the precise drink before using it for guests with dietary restrictions.
Waitrose
Waitrose describes Essential Unsweetened Soya Drink as a fortified UHT drink.
- Its product information identifies an unsweetened long-life format.
- Check the current carton for an explicit gluten-free claim; an ingredient list alone does not establish that labelling status.

Questions about Christmas baking
What does “gluten free” mean on a UK soya drink?
UK Food Standards Agency guidance, revised in March 2025, says food labelled gluten free must contain no more than 20 mg/kg of gluten as sold. Look for the explicit claim on the current carton rather than assuming every soya drink qualifies.
Does gluten-free soya drink make a Christmas cake gluten free?
No—the other ingredients need checking too. Good Food’s gluten-free adaptation of a vegan cake calls for both gluten-free self-raising flour and a gluten-free milk alternative; check baking powder, chocolate and decorations in your own recipe as well.
Should I choose a no-sugars soya drink for baking?
A no-sugars drink is useful when you want the recipe’s measured ingredients to determine sweetness. Asda Groceries lists 0 g sugars per 100 ml for Alpro Organic Soya No Sugars Long Life and Alpro Soya No Sugar Chilled, compared with 2.5 g per 100 ml for Alpro High Protein Soya Original. Check the precise drink you buy.
How long can I keep long-life soya drink after opening?
Follow the instructions on the specific carton and refrigerate it when directed. Sainsbury’s says to use its Unsweetened Long Life Soya Drink within three days of opening; Asda Groceries gives five days for Alpro Organic Soya No Sugars Long Life.
Is a gluten-free soya drink suitable for someone with a soya allergy?
No. A gluten-free claim does not remove soya from a soya drink. Check the product’s allergen statement and use a different ingredient for someone with a soya allergy.
