What to check before buying
Decide which taste the household wants, compare nutrition on a per-100ml basis, then check where unopened cartons can be kept and what happens after opening.

What to check |
Your needs |
| Sugar and taste |
Compare sugars per 100ml on the exact variant. Tesco Groceries lists 0.5g for Tesco Longlife Unsweetened; Waitrose & Partners lists 0g for Essential Unsweetened; Sainsbury’s lists 2.3g for its Sweetened Soya Drink. |
I want an unsweetened drink for cereal or savoury cooking, or a sweeter one because that is what my household prefers. |
| Fortification |
Look for added calcium, iodine, vitamin D and vitamin B12 on the carton. Tesco Longlife Unsweetened and Waitrose Essential Unsweetened list all four; check the formulation of any other variant separately. |
If soya drink regularly replaces dairy milk at breakfast, I want to know which nutrients the particular carton contains. For a child aged 1 or over, NHS North West Knowledge Now’s allergy guidance makes this check especially relevant. |
| Protein |
Compare grams per 100ml, using the same basis for each drink. Tesco Groceries lists 3.4g for its Longlife Unsweetened drink; Sainsbury’s lists 2.0g for its Sweetened Soya Drink. |
Protein content matters to my choice of a drink for cereal or smoothies, so I want the figure for the carton I am buying rather than an assumption about soya drinks generally. |
| Storage and heating |
Check whether the unopened carton is long-life or chilled, then read its opened-life instructions. Waitrose & Partners says to keep Essential Unsweetened below 5°C after opening and use it within 3 days; its guidance advises gentle heating to reduce separation. |
I may keep unopened cartons for several weekends, but need space in the fridge and a plan to use each carton once opened. For hot drinks or cooking, I also want to know how the drink behaves when heated. |
| Soya allergen |
Read the ingredients and allergen statement on every carton. GOV.UK allergen guidance identifies soybeans as an allergen that food businesses must declare when present as an ingredient. |
Someone using this drink must avoid soya; a dairy-free label does not make a soya drink suitable for them. |

Questions about soya drinks
What should I check for cereal and porridge?
Compare sugars per 100ml according to the taste you want, then check protein and added nutrients on the exact carton. Tesco Longlife Unsweetened and Waitrose Essential Unsweetened list added calcium, iodine and vitamins D and B12; do not assume another variant has the same formulation.
Is sweetened soya drink an option for breakfast?
Yes, if your household prefers its taste. Compare the nutrition panels: Sainsbury’s lists 2.3g sugars per 100ml for its Sweetened Soya Drink, while Waitrose & Partners lists 0g per 100ml for Essential Unsweetened. Those figures describe the named products, not all sweetened or unsweetened drinks.
Can I keep several long-life cartons for future weekends?
A long-life carton can be kept unopened according to its pack instructions and best-before date. Opening changes the storage requirement: Waitrose & Partners says to refrigerate Essential Unsweetened below 5°C and use it within 3 days. Check the instructions on each product before deciding how many cartons to open.
What if soya drink separates in a hot drink?
Follow the heating directions for the particular carton. Waitrose & Partners advises heating its Essential Unsweetened drink gently for cooking and allowing boiling water to cool slightly before adding the drink, to reduce separation.
Does dairy-free mean suitable for someone with a soya allergy?
No. A soya drink is not suitable for someone who must avoid soya. GOV.UK allergen guidance identifies soybeans as an allergen that food businesses must declare when present as an ingredient, so check the ingredients and allergen statement on the exact pack.
