For third-party confirmation of vegan status, look for the Vegan Trademark on the current carton; ASDA Plant Based Soya Unsweetened is listed with the Vegan Society logo. For gravy, mash or a savoury sauce, compare unsweetened drinks and their listed sugars, then follow the pack’s heating instructions because soya drink can separate in hot recipes. A “suitable for vegans” declaration is useful, but it is not the same as a named third-party certification.
The right carton depends on whether certification, savoury cooking or particular label details matter most for your roast dinner.
If a general vegan declaration is not enough for your meal, check the exact carton for the Vegan Trademark. The Vegan Society says its scheme checks ingredients and the manufacturing process against its standards.
Compare unsweetened cartons when you do not want to add sweetness to a savoury recipe. Check the heating directions too: Tesco and Waitrose caution that soya drink can curdle or separate in hot preparations.
If fortification is part of your choice, compare the current cartons for calcium, iodine and vitamins D and B12 rather than assuming every soya drink has the same formulation.
Start with the vegan status required for your meal, then check the formulation and instructions against the dish you are making.
| Priority | What to check | Your needs |
|---|---|---|
| Vegan status | Look for the Vegan Trademark on the exact carton if you require third-party certification. The Vegan Society says it checks ingredients and manufacturing against its standards; a “suitable for vegans” statement does not itself establish registration with that scheme. | I want independent confirmation for every ingredient in the roast dinner, rather than relying on a plant-based description. |
| Sweetness | Compare the ingredients and sugars per 100 ml. Tesco Unsweetened lists 0.4 g, Waitrose Essential Unsweetened 0.0 g and ASDA Plant Based Unsweetened less than 0.5 g; Alpro Soya Original lists sugar as an ingredient and 2.5 g sugars per 100 ml. | For my gravy or mash, I would rather start with an unsweetened drink and adjust the recipe’s flavour myself. |
| Heating | Read the carton’s hot-use directions. Waitrose advises gentle heating and removing its soya drink from the heat before boiling; Tesco says not to mix its unsweetened drink with boiling water. | My sauce needs to stay together as I warm it, so the preparation instructions matter as much as the label on the front. |
| Allergens | Check the current allergen statement, including precautionary wording. The Food Standards Agency identifies soya as a risk for people with a soya allergy; ASDA Plant Based Soya Unsweetened also states that it may contain nuts. | If someone eating the roast must avoid soya or nuts, a vegan label alone does not answer that requirement. |
| Fortification | Compare each carton’s ingredient and nutrition information for the added nutrients you want. Listed nutrients differ between products and variants; Sainsbury’s Unsweetened Soya Drink, for example, lists calcium, iodine and vitamins D and B12. | I want to compare added nutrients as well as whether the drink works for my recipe. |
A product description and the Vegan Trademark provide different kinds of assurance. The Vegan Society describes defined standards for its mark and renews registration yearly.
If third-party certification matters for the meal, check for the mark on the exact carton you intend to use.
Listed sugars differ: Alpro Soya Original contains sugar and lists 2.5 g sugars per 100 ml, while the cited Tesco, ASDA and Waitrose unsweetened drinks each list less than 0.5 g per 100 ml.
For a savoury gravy or sauce, start by comparing unsweetened cartons, then season the finished dish to suit the recipe.
Waitrose warns that soya alternatives can curdle or separate easily when used in cooking.
Heat gently and remove from the heat before boiling, following the directions for your chosen carton and recipe.
Vegan suitability does not remove soya or precautionary nut statements. ASDA Plant Based Soya Unsweetened declares soya and states that it may contain nuts.
Read the current label for everyone eating the meal; do not use soya drink for a person who needs to avoid soya.
These details concern the named drinks, not every product made by each brand; check the carton of the variant you choose.

Look for the Vegan Trademark on the exact carton. The Vegan Society says it checks ingredients and the manufacturing process against its standards; a “plant-based” or “suitable for vegans” label does not, by itself, confirm registration with that scheme.
An unsweetened drink is a starting point when you do not want to add sweetness. Tesco, ASDA and Waitrose list 0.4 g, less than 0.5 g and 0.0 g sugars per 100 ml respectively for their named unsweetened drinks; Alpro Soya Original lists sugar as an ingredient and 2.5 g sugars per 100 ml. The final flavour will still depend on your recipe.
Follow your carton’s instructions and avoid boiling where directed. Waitrose advises heating its soya drink gently and removing it from the heat before it boils; Tesco says not to mix its unsweetened drink with boiling water.
No. The Food Standards Agency identifies soya as a possible risk for people with a soya allergy. Read the current allergen statement for any additional warnings: ASDA Plant Based Soya Unsweetened, for example, also states that it may contain nuts.
Follow the storage and use-by-after-opening directions on that particular carton. Instructions can differ between drinks and formats, so check them before opening a carton for roast-dinner preparation.
