Tea drinkers who prefer less sweetness
If you add soya drink to a bedtime tea, compare the carton’s ‘of which sugars’ value rather than assuming every original or unsweetened recipe tastes or measures the same.
Who might use this guide?
Households working through a carton
A 1-litre carton may be convenient for regular drinks, but its instructions for refrigeration and use after opening matter whether it was sold chilled or long-life.
People comparing dairy alternatives
If the drink regularly takes the place of dairy milk, check its calcium, vitamin D, vitamin B12 and iodine information. The UK Office for Health Improvement and Disparities says nutrient content varies considerably between plant-based drinks.
What should you check?
Start with the flavour and carton size you will use, then compare the label and preparation instructions on those specific drinks.
| Priority | What to check | Your needs |
|---|---|---|
| Sweetness | Compare ‘of which sugars’ on like-for-like labels, noting whether the value is per 100 ml or per 100 g. M&S lists 0.4 g per 100 g for its unsweetened drink and 2.0 g per 100 g for its sweetened Plant Kitchen drink. | I would rather choose the sweetness of my bedtime drink than rely on the word ‘original’ or ‘unsweetened’ alone. |
| Fortification | Look for calcium, vitamin D, vitamin B12 and iodine on the individual carton. The UK Office for Health Improvement and Disparities notes that plant-based drinks vary considerably in nutrient content. | If I use soya drink regularly instead of dairy milk, I want to know which nutrients this particular carton lists. |
| Hot-drink use | Read the serving and heating directions. Sainsbury’s advises letting hot water cool slightly before adding its unsweetened soya drink; Waitrose advises gentle heating rather than boiling its drink. | A smooth texture in tea matters to me, so I can follow the preparation directions for the carton I buy. |
| Storage | Distinguish storage before opening from instructions after opening. Waitrose says to refrigerate its Essential Unsweetened carton and use it within 3 days of opening; the Alpro No Sugar carton listed by Waitrose says to use it within 5 days. | Will I finish a 1-litre carton within its stated period after opening, even if I only use a little each evening? |
| Allergens | Read the current ingredients and allergen information for the intended drinker. GOV.UK lists soybeans among the allergens for which food businesses must provide information. | Before serving it to someone else, I need to check that soya and any other declared allergens are suitable for them. |

Assuming plant-based cartons have the same added nutrients
The UK Office for Health Improvement and Disparities says their nutrient content varies considerably and notes that UK organic plant-based drinks cannot be fortified with nutrients.
If fortification matters to your choice, compare calcium, vitamin D, vitamin B12 and iodine on the specific carton rather than relying on ‘plant-based’ or ‘organic’.
-
Choosing an original drink when you want an unsweetened one
Recipes differ: M&S lists 2.0 g sugars per 100 g for its sweetened Plant Kitchen drink and 0.4 g per 100 g for its unsweetened drink.
Compare the ‘of which sugars’ values on the cartons you are considering, alongside the flavour you prefer.
-
Overlooking hot-drink directions
Sainsbury’s warns that its unsweetened soya drink can separate when added to very hot water, while Waitrose advises gentle heating for its soya drink.
Let the water cool slightly before adding the Sainsbury’s drink, and follow the heating instructions on whichever carton you use.
-
Treating long-life as a post-opening instruction
Long-life cartons still have instructions for after opening. Waitrose specifies 3 days for its Essential Unsweetened drink; the Alpro No Sugar carton listed by Waitrose specifies 5 days.
Choose a carton size you can use within its own stated period and follow its refrigeration instructions.
Brand and retailer references
These examples show why it is worth comparing individual cartons rather than treating a brand’s whole soya-drink range as one recipe.
Alpro
Alpro has original and no-sugars long-life soya drinks in the cited UK retailer listings.
- The No Sugar carton listed by Waitrose has added calcium, iodine and vitamins B2, B12 and D2, and lists 0 g sugars per 100 ml.
- That listing says to refrigerate after opening and use within 5 days; check the instructions on the carton you purchase.
Tesco
Tesco’s own-label range is another place to compare soya-drink cartons.
- Use the current carton to compare sugars, fortification, allergens and storage instructions with other drinks.
Sainsbury's
Sainsbury’s Unsweetened Soya Drink is a chilled 1-litre option.
- Sainsbury’s lists added calcium, iodine, vitamin D and vitamin B12, with less than 0.5 g sugars per 100 ml.
- Its hot-drink directions advise allowing water to cool slightly before adding the soya drink to avoid separation.
Asda
Asda’s own-label soya drinks offer another carton-label comparison.
- Check the specific pack for ingredients, nutrition, fortification and instructions before comparing it with another brand.
M&S
M&S lists both unsweetened and sweetened Plant Kitchen soya drinks.
- Its cited unsweetened drink lists 0.4 g sugars per 100 g; the sweetened Plant Kitchen drink lists 2.0 g per 100 g.
- Check which recipe you have picked rather than assuming the two cartons have the same sugar value.
Waitrose
Waitrose Essential Unsweetened is a long-life 1-litre soya drink.
- Waitrose lists added calcium, vitamin D, B12, B2 and iodine, with 0.0 g sugars per 100 ml.

Common questions
Is unsweetened soya drink always the right choice for bedtime?
No: choose it if you prefer less sweetness, but compare the exact recipes. M&S lists 0.4 g sugars per 100 g for its unsweetened drink and 2.0 g per 100 g for its sweetened Plant Kitchen drink; flavour and the carton’s other label details still matter.
Can I add soya drink to hot tea?
Yes, but follow the directions for your carton. Sainsbury’s advises letting hot water cool slightly before adding its unsweetened soya drink to avoid separation, while Waitrose advises heating its drink gently rather than boiling it.
Do all soya drinks list the same added nutrients?
No. The UK Office for Health Improvement and Disparities says plant-based drinks vary considerably in nutrient content. If fortification matters to your purchase, check the individual carton for calcium, vitamin D, vitamin B12 and iodine.
What if someone drinking it has a soya allergy?
Do not serve a soya drink to someone who needs to avoid soya. GOV.UK lists soybeans among the allergens for which food businesses must provide information; read the current product label for soya and any other declared allergens.
